Lactic Ferments and Kefir Inoculation Calculator

Calcolatore Inoculo Fermenti Lattici e Kefir

Stima la quantità di fermento da inoculare in base al volume di latte o bevanda vegetale, al tipo di fermento e al dosaggio desiderato.

The app Calcolatore Inoculo Fermenti Lattici e Kefir is a professional tool designed to accurately estimate the amount of cultures to inoculate in the processing of milk and plant-based beverages.
It is intended for artisan laboratories, farms, and producers of yogurt, kefir, skyr, and fermented plant-based alternatives who wish to manage fermentation in a controlled way, avoiding waste or incorrect dosages.

Main Features

  • Automatic calculation of the optimal amount of cultures in grams or milliliters.
  • Compatibility with various types of milk (cow, goat, sheep) and plant-based beverages (soy, oat, almond).
  • Customization of the dosing (%) based on fermentation conditions.
  • Technical indications on the most common culture strains for each product type.
  • “Copy Results” button to export or note laboratory data.

How It Works

  1. Enter the volume of milk or beverage to ferment (in liters).
  2. Select the type of milk or plant base.
  3. Choose the type of culture to use (yogurt, kefir, skyr, fermented plant-based beverage).
  4. Enter the desired dosing (%) relative to the total volume.
  5. Click on “Calculate Inoculation”: the app shows the required inoculation amount and a technical summary.

Practical Example

  • Volume: 50 L of cow’s milk
  • Culture: yogurt
  • Dosing: 1.5%
    → Required inoculation amount: 1.88 g/ml

This calculation can be easily adapted by changing the type of culture or dosing to optimize fermentation based on temperature, time, and fat content of the milk.

Benefits

  • Planning daily fermentations.
  • Precision in dosing cultures and controlling batches.
  • Optimization of fermentation times and product quality.
  • Usable also for experimental trials or technical training.

FAQ – Frequently Asked Questions

1. Can I input custom dosing values?
Yes, you can modify the inoculation percentage based on your recipe or the strength of the culture used.

2. Does the app handle both powder and liquid cultures?
Yes, the values are indicative in g/ml, adaptable to both forms.

3. Are the dosing coefficients modifiable?
Sure, they are set in the $standard array and can be customized.

4. Can I use the app for artisanal plant-based beverages (e.g., oat, rice, almond)?
Yes, just select “Fermented Plant Beverage.” The app takes into account higher average inoculation levels.

5. Is the app useful for laboratory trials as well?
Absolutely yes. It is ideal for assessing yields and fermentation speeds in small experimental batches.

6. Is it compatible with smartphones or tablets?
Yes, the layout is readable and optimized for direct use in laboratory or production environments.
