water activity - Opis:
- Lactic acid bacteria have shown positive health effects and are widely distributed as dry products. They are widespread applied in functional dairy products, dietary supplements and as pharmaceutical products. Freeze-drying is a process of removing water by sublimation and is one of the most effective preservation technology. The aim of the present study was to establish impact of oxygen and humidity on freeze-dried Lactobacillus gasseri during the preparation of the powder and storage time. Lyophilisate was rubbed in aerobic and anaerobic condition with low humidity. Survival test and water activity was investigated after freeze-drying and storage in two different temperatures. The preservation of bacteria was improved when after freeze-drying process lyophilisate have not contact with oxygen and humidity. Survival rates of bacteria was the highest during storage at anaerobic condition both at 4-6 °C and 25 °C. The results shown that it is sufficient to crush of freeze-dried and packaged under anaerobic conditions to achieve higher survival of bacteria.
