Fermentation has transformed food for centuries. Planit focuses specifically on aerobic fermentation—the oxygen-dependent method used to make foods such as tempeh and koji—rather than fermentation performed in sealed vessels, brines or oxygen-free environments.

The Planit POD makes this traditionally hands-on process controlled, repeatable and practical by managing temperature, humidity, airflow and time. Because production takes place on-site, chefs maintain control over the ingredients and finished food—supporting fresh, minimally processed preparation without relying on artificial preservatives to create flavor or texture.

Fermentation can help make more of the food’s existing nutrition accessible. During the process, culture-produced enzymes act on naturally occurring compounds within legumes, grains and other plant-based ingredients.

This activity may reduce compounds such as phytates, which can limit the body’s absorption of certain minerals. The degree of change varies by ingredient and process, but the benefit is rooted in unlocking more value from nutritious whole-food ingredients—not adding isolated nutrients afterward.

Fermentation develops peptides and amino acids—including naturally occurring glutamates—that create richer, more rounded flavor. This deep savory quality is known as umami, the fifth taste associated with foods such as aged cheeses, mushrooms, miso and slow-cooked stocks.

Koji is particularly valuable because it produces enzymes that continue working in sauces, marinades and other applications. These enzymes can enhance proteins, deepen simple ingredients and build satisfying flavor with less dependence on added salt, fat or artificial flavor systems.

Fermentation partially transforms complex components of food before they reach the digestive system. In legumes and grains, this may include reducing some of the oligosaccharides associated with gas and digestive discomfort, while making proteins and carbohydrates easier to process.

Planit foods are pasteurized at the completion of their programmed cycle, so these benefits do not depend on consuming live probiotic cultures. They result from the transformation that has already taken place during fermentation.

Traditional tempeh begins with soybeans. Planit opens the format to a much broader range of ingredients, giving chefs a way to transform familiar legumes, grains, seeds and other compatible foods into fresh, cohesive cultured cakes.

Planit’s roasted chickpeas and ivory lentils are dependable, kitchen-ready starting points. They produce tempehs with visibly recognizable ingredients, firm texture and their own distinct flavor—but they are not intended to limit the chef. Other ingredients and combinations can be explored within validated preparation and food-safety parameters.

Culture selection provides another layer of control. Planit’s Traditional Tempeh Culture develops the familiar earthy aroma and velvety, cake-like character associated with Rhizopus fermentation. Planit's Universal Starter Culture produces a milder, more savory profile with less of the traditional mushroom character.

The chef controls the base ingredient, flavor direction and finished application. Planit tempeh can be sliced, seared, grilled, smoked, marinated, glazed, fried or crumbled—working as a center-of-plate protein, sandwich component, topping or ingredient within another dish.

Fresh koji is a whole new drawer in the chef’s fresh-flavor toolbox. It is not a finished dish, but an enzyme-rich ingredient that can be used to season, sweeten, age, tenderize and develop entirely new flavors.

The process begins by growing Planit’s Aspergillus oryzae culture on cooked rice inside the POD. As the culture develops, it produces enzymes that break proteins into savory amino acids and convert starches into natural sugars. The result is fresh koji that can become a flavor base, a seasoning system or the starting point for additional fermentation.

Four Signature Applications of Fresh Koji

The POD creates the fresh koji. From there, each application follows its own secondary process: amazake uses controlled warmth; koji aging takes place under refrigeration; and shio koji and miso mature separately in appropriate fermentation vessels.

These four applications are starting points—not the limits of the platform. Fresh koji can also support custom marinades, rubs, savory pastes, cultured condiments, flavor concentrates and signature ingredients unique to the kitchen.

Ground Protein gives chefs an alternative to relying solely on frozen, trucked-in plant-based products that arrive fully formulated, preserved and locked into someone else’s flavor system. Many conventional options are designed to imitate a specific meat product and may depend on long ingredient panels, added flavors and highly engineered textures.

Planit starts differently. A shelf-stable blend of plant-protein ingredients is hydrated and fermented with Universal Koji Culture inside the POD. During the programmed cycle, the culture develops throughout the mixture, helping create a cohesive texture and clean, savory flavor. The cycle concludes with automatic pasteurization, producing approximately 4.5 pounds of fresh Ground Protein in a single tray.

What happens next belongs to the chef. The protein can be seasoned before or after fermentation and shaped around the intended cuisine—not around a predetermined burger profile. It can become patties, meatballs, kebabs, kofta, dumpling fillings, crumbles, ragù, stuffed vegetables, sandwich fillings or composed center-of-plate dishes.

It can also be treated as an ingredient rather than a finished protein format: diced, crumbled, blended into a recipe or combined with vegetables, grains, aromatics and house seasoning. The result is clean, fresh and yours—made on-site with control over flavor, texture and final use.

The three platforms solve different culinary needs:

• Choose Reinvented Tempeh when you want a sliceable or crumble-ready whole-food protein with visible ingredients, a firm bite and a distinct fermented character.
• Choose Koji and Flavor Fermentation when the objective is flavor development—seasoning, sweetness, marinades, sauces, aging, tenderization or signature fermented ingredients.
• Choose Ground Protein when you need a cohesive, formable protein that can be customized for a particular cuisine, used as a center-of-plate item or incorporated into another recipe.

The platforms can also work together. Koji-based seasonings can flavor tempeh or Ground Protein, while all three can contribute different textures, flavors and functions to the same menu.

There is a difference between serving differentiated food and becoming a differentiated chef. The deeper opportunity is authorship: developing ingredients, flavors and techniques that reflect the chef’s own point of view—and that guests, peers and team members begin to associate with that chef or kitchen.

This follows the natural arc of the craftsman: curiosity leads to practice; practice develops control; control becomes a signature; and a signature creates recognition. Planit gives chefs another area in which to build that mastery—not simply by finishing a purchased product differently, but by participating in the creation of the food itself.

A fresh, whole-legume tempeh grown in-house is very different from adding chickpeas to a menu. It can be designed around the kitchen’s preferred ingredients, culture, flavor profile, texture and finishing technique—becoming a customized, signature expression of tempeh that cannot simply be ordered from the same distributor by another restaurant.

The emotional benefit is ownership. The chef can say, with substance, “We make this here.” That creates pride, strengthens the kitchen’s creative culture and gives guests something they can identify with the people and place behind the food.

Fermentation adds more than flavor—it gives chefs access to enzymes as culinary tools. These enzymes can continue transforming ingredients after the primary ferment is complete, creating effects that seasoning alone cannot fully reproduce.

A primary ferment happens inside the POD. The selected culture grows under controlled conditions, transforming the prepared ingredient into fresh tempeh, koji or Ground Protein. That process establishes the ingredient’s basic structure, aroma, flavor and functionality.

A secondary application begins after the POD has done its job. Fresh koji can become shio koji, miso or amazake, or it can be applied directly to other foods through marinades, pastes, rubs and aging techniques.

Koji’s protease enzymes act on proteins, helping create savory amino acids, tenderness and deeper umami. Its amylase enzymes act on starches, releasing natural sweetness and supporting better browning. That combination gives chefs several practical flavor-development tools:

• Marinades and shio koji can season more deeply while supporting tenderness, moisture retention and browning.
• Koji rubs and aging preparations can transform beef, pork, poultry, seafood and vegetables over a controlled period under refrigeration.
• Miso and fermented flavor bases can add concentrated savory depth to sauces, glazes, broths, dressings and compound butters.
• Amazake can provide natural sweetness, body and subtle fermented complexity in beverages, desserts, sauces and baking.

The result is not simply “more umami.” It is greater control over how flavor develops—through protein transformation, starch conversion, aging, fermentation and the interaction between the chef’s ingredients and technique.

Planit converts shelf-stable foods and cultures into fresh ingredients inside the kitchen. Instead of receiving every protein or flavor component in its finished form, the operation produces what it needs on-site and determines how that ingredient will be seasoned, finished and served.

House production creates practical transparency. The kitchen knows the source ingredients, production date, culture used and preparation method. It also creates a more meaningful story: the food was not simply unpacked and reheated—it was grown, transformed and finished by the kitchen.

Fresh production can also change how the chef approaches the menu. Tempeh can be made for a specific dish rather than adapted from a generic purchased format. Koji can be directed toward the sauces, proteins and flavor systems the kitchen actually uses. Ground Protein can be finished differently across multiple applications instead of arriving locked into one product identity.

Planit foods are pasteurized at the completion of their programmed cycle, so “fresh” does not mean live or probiotic. It means recently produced, minimally handled and under the kitchen’s control. Like other fresh prepared foods, it must be cooled, stored and managed according to proper food-safety procedures.

Everything that comes out of the POD belongs to the chef. The finished tempeh or Ground Protein can be sliced, marinated, seasoned, smoked, grilled, roasted, crumbled, ground, sauced, shaped or incorporated into another recipe. That is where much of the chef’s customization—and the real culinary opportunity—begins.

But customization should follow mastery of the proven process.

Planit strongly recommends that new users begin with the specified Planit foods, cultures, quantities, preparation methods, tray depths and POD programs. These methods have been developed to produce reliable growth, proper pasteurization and consistent finished results. Following them establishes a successful benchmark and allows the chef to understand what the system is designed to produce.

Once that benchmark has been achieved consistently, chefs can begin personalizing the culinary result. Start with post-POD seasoning, sauces, marinades, cooking methods, shapes and applications. When exploring changes to ingredients or fermentation variables, adjust one factor at a time and remain within validated food-safety guidance.

Unproven changes to hydration, ingredient composition, culture level, tray depth, temperature or fermentation time can produce inconsistent growth—and may create food-safety risks. The principle is simple:

Standardize the process first. Then customize the food.

That balance gives chefs both reliability and creative freedom. Planit handles the proven fermentation work; the chef takes ownership of what the finished ingredient becomes.

The economic advantage begins with finished yield—not simply the purchase price of the dry ingredients. The example below follows one Planit Ground Protein “burger” batch through ingredient cost, finished-food cost, competitive comparison and potential monthly contribution.

Economics Example

This is an ingredient-level example—not a promise of net profit. Labor, utilities, freight, waste, menu accompaniments, overhead and actual selling price must be included in each operator’s calculation. Even with those qualifications, the example demonstrates the underlying potential: converting shelf-stable inputs into fresh, differentiated food at a competitive finished cost and strong gross contribution.

Additional operational value can come from shelf-stable inventory, reduced dependence on frozen finished products, predictable production cycles and cross-utilization. One Ground Protein batch can support several menu applications, while one batch of fresh koji can contribute to sauces, marinades, seasonings, aging preparations and desserts.

The most useful measure is therefore not simply “What does a Planit package cost?” It is:

What does the finished food cost per usable pound and plated serving—and how much menu value can the kitchen create from it?

The Planit POD by Waring is the equipment at the center of the system—but it is not the complete system by itself. Its job is to create and maintain the controlled environment required for reliable aerobic fermentation.

Fermentation cultures are living organisms. Their performance depends on the relationship between temperature, humidity, airflow, time, food preparation and available oxygen. In an uncontrolled environment, small changes in any of these conditions can produce major differences in growth, flavor, texture and safety.

The POD manages the environmental variables through dedicated programs developed for Planit’s primary food platforms. Once the prepared and inoculated food is loaded correctly, the selected program controls the conditions required for fermentation and then transitions into a pasteurization stage at the end of the cycle.

Each program is built around a different biological and culinary objective:

• Tempeh supports the growth required to bind prepared legumes and other compatible ingredients into a cohesive cultured cake.
• Koji provides the longer controlled process needed for Aspergillus oryzae to grow on prepared rice and produce an enzyme-rich fresh koji.
• Planit Blends supports the fermentation and binding of Ground Protein into a cohesive, cookable tray.

The POD creates consistency, but it does not correct improper preparation. Accurate hydration, cooking, cooling, culture measurement, mixing, tray depth, sanitation and loading remain essential. It also does not replace proper cooling, refrigerated storage or final food preparation after the programmed cycle is complete.

The best way to understand the POD is as a precision production tool: it removes much of the environmental guesswork from fermentation so the kitchen can focus on preparation, finishing and culinary use.

Planit foods and cultures are not simply products that happen to be used in the POD. They have been selected, prepared, portioned and tested as functional parts of the system.

A fermentation substrate is the food on which the selected culture grows. Its size, moisture, density, surface condition and nutrient composition all affect how air moves through the food and how evenly the culture develops.

Planit’s roasted chickpeas and ivory lentils provide dependable starting points for Reinvented Tempeh. Their preparation reduces unnecessary kitchen steps while providing recognizable whole-legume ingredients with different flavors and textures.

Ground Protein Texture Mix is formulated differently. Its plant-protein ingredients hydrate into a mixture that allows Planit’s Aspergillus oryzae culture to develop throughout the tray and create a cohesive finished structure. Burger Spice Blend provides a tested savory profile for the burger application, while the fermented Ground Protein itself can support many other culinary directions.

Fresh rice koji begins with properly cooked rice—typically basmati or jasmine—prepared by the operator and inoculated with the appropriate Planit koji culture. Rice preparation matters: the grains must provide sufficient moisture for culture growth while remaining separate enough to allow airflow and even development.

These foods are reliable starting points, not statements that chefs can never explore other ingredients. They establish a proven baseline from which responsible experimentation can eventually begin.

Planit foods and cultures are not simply products that happen to be used in the POD. They have been selected, prepared, portioned and tested as functional parts of the system.

Starter culture is not simply a seasoning. It is the biological engine of the process. Culture identity, quality, viability, dosage and distribution all influence growth, flavor, texture and enzymatic activity.

Planit offers different cultures for different production and culinary objectives:

• Traditional Tempeh Starter Culture — Rhizopus oligosporus
  
  Recommended when the goal is the familiar white growth, earthy aroma and velvety cohesion associated with traditional tempeh.
• Universal Starter Culture — Aspergillus oryzae
  
  Our economical and versatile culture for routine production. We recommend Universal Starter Culture for Ground Protein Texture Mix, where it develops throughout the mixture and helps produce a cohesive, savory finished tray. It can also be used with Planit legumes to make a milder, less mushroom-forward style of Reinvented Tempeh.
  
  Universal Starter Culture can be used to produce rice koji as well. It is a practical option when cost efficiency or broad utility is the primary objective.
• Artisan Koji Starter Culture — Aspergillus oryzae
  
  Recommended when the primary objective is robust, dynamic fresh koji for culinary flavor development. It is our preferred culture for chefs planning to use fresh koji in shio koji, amazake, miso, marinades, aging preparations and other enzyme-driven applications.

The distinction is important: both Universal and Artisan cultures are Aspergillus oryzae, but they are offered for different use priorities. Universal provides economical versatility across Ground Protein, Reinvented Tempeh and koji. Artisan is the recommended choice when fresh koji itself—and its culinary and enzymatic potential—is the intended result.

Too little culture, uneven mixing or incorrect food temperature can lead to incomplete growth. Adding more culture than specified does not necessarily improve the result. Consistency comes from using the appropriate culture, in the specified amount, with the correct substrate, preparation method and POD program.

This is why Planit foods, cultures and preparation methods should initially be treated as one validated production framework—not as independent ingredients to be changed casually.

Successful fermentation depends on several coordinated parts, each with a specific job:

Planit food or properly prepared rice

• Provides the structure, moisture and nutrients on which the selected culture develops.

Planit starter culture

• Performs the biological transformation and produces the desired growth, cohesion or enzymatic activity.

Planit Preparation Guides (visit here)

• Defines the proper cooking or hydration, cooling temperature, culture dosage, mixing method, tray depth and other application-specific steps.

Planit POD programs

• Manages the temperature, humidity, airflow, time and end-of-cycle pasteurization required for the selected food platform.

Kitchen operator

• Maintains sanitation, follows the Preparation Guide, measures and mixes accurately, loads the POD correctly, cools and stores the finished food, and determines its final culinary use.

In practice, the system follows a clear production sequence:

1. Choose the food platform.
   
   Determine whether the objective is fresh tempeh, rice koji or Ground Protein, then select the corresponding Planit Preparation Guide.
2. Prepare the substrate according to the Preparation Guide.
   
   Cook or hydrate the specified food using the listed quantities and method. The correct moisture level and physical structure are essential to airflow and culture growth.
3. Cool and inoculate.
   
   Bring the food to the temperature specified in the Preparation Guide, measure the recommended culture accurately and distribute it evenly. Introducing culture while the food is too hot can damage it; uneven distribution can create inconsistent fermentation.
4. Load the POD correctly.
   
   Follow the Preparation Guide for tray selection, depth, density and loading. Overfilling, compacting or changing the specified depth can affect airflow, heat movement and growth.
5. Run the matched program.
   
   Select the POD program identified in the Preparation Guide. During the cycle, the culture grows, generates heat and transforms the food’s flavor, texture or enzymatic potential.
6. Complete pasteurization.
   
   The programmed cycle transitions to pasteurization, stopping active culture growth and completing an important food-safety step.
7. Cool, store and finish.
   
   Follow the Preparation Guide for removal, cooling and refrigerated storage. The chef can then apply the desired seasoning, cooking method, format or secondary application.

No single part produces the result alone. The POD cannot compensate for poorly prepared food. Premium culture cannot overcome incorrect temperature or hydration. A proven method cannot remain consistent without the controlled environment.

The Planit system works because the equipment, foods, cultures, Preparation Guides and operator each handle a different part of the process. Together, they turn fermentation from an unpredictable craft experiment into a repeatable culinary production capability.
