ESL – longer shelf life

ESL stands for extended shelf life. Suitable processes enable a longer shelf life while maintaining continuous refrigeration. The specific technical treatment used cannot be fully determined from the three letters alone.

When shopping, it is helpful to compare specific products rather than general buzzwords. Ingredients, processing, storage and composition each answer different questions. Individual health restrictions cannot be assessed generally from this information.

03 / DEEP DIVE

UHT milk – shelf-stable when unopened

Ultra-high temperature treatment and aseptic filling make UHT milk shelf-stable at room temperature when unopened. Once opened, it must also be refrigerated. Heat can alter the taste and individual ingredients.

When shopping, it is helpful to compare specific products rather than general buzzwords. Ingredients, processing, storage and composition each answer different questions. Individual health restrictions cannot be assessed generally from this information.

04 / DEEP DIVE

Shelf life is not a taste ranking

The choice depends on storage, refrigerator space, use and personal preferences. The storage instructions on the packaging take precedence over general rules of thumb.

Where does raw donkey milk stand?

Raw milk is not pasteurized fresh milk. It may contain pathogens and must be heated safely in accordance with official recommendations. Pregnant women, children, older people and immunocompromised individuals must exercise particular caution.

DON DONKEY’S® PERSPECTIVE

Making informed choices about special foods

In our interactions with customers, we experience that people explore their diet for various reasons – sometimes also during physically demanding phases of life. Such personal motivations are not scientific evidence of health effects. DON DONKEY’S® considers donkey milk a special food, not a medicine or medical food.

For raw milk, the official recommendations for safe heating are particularly important. Particular caution is required for at-risk groups. Please follow the product information and seek professional advice for medical conditions.

Frequently Asked Questions

What should I check on the packaging?

Product name, ingredients, nutritional values, processing, shelf life and storage. This information is more informative than a single marketing term.

Is donkey milk automatically easier to tolerate?

No. A generally better tolerance has not been proven. Donkey milk contains lactose and milk proteins; if you have an intolerance or allergy, an individual assessment is necessary.

Can raw milk be used without concern?

No. Raw milk may contain pathogens and should be heated safely in accordance with official recommendations.
