A technique for improving heat resistance of a bacterium is provided. By mixing the bacterium with an oil or fat and an emulsifier, heat resistance of the bacterium can be improved.

The present disclosure relates to a method of producing lactic acid bacteria dual-coated with protein and polysaccharide by using a protein hydrolysate, and lactic acid bacteria having a dual coating, produced by the method. The lactic acid bacteria having a dual coating of protein and polysaccharide, produced according to the present disclosure, have very excellent dry-freezing viability, acid resistance and bile resistance. Accordingly, the lactic acid bacteria having a dual coating of protein and polysaccharide according to the present disclosure will be very useful for the production of fermented milk, processed milk, fermented soy products, processed foods, functional beverages, functional foods, common foods, etc.

The disclosure provides an oral composition for reducing serum cholesterol, serum lipids, body fat, or atherogenic index or for prophylaxis or treatment of atherosclerosis, cardiovascular or cerebrovascular diseases, comprising a highly bsh active bacteria, isolate or supernatant thereof; wherein the highly bsh active bacteria degrades >50 mol glycodeoxycholic acid (GDCA)/gram/hour and >2 mol taurodeoxycholic acid (TDCA)/gram/hour when measured over 1 hour and 5 hours, respectively, or degrades >65 mol GDCA/g/hr and >7 mol TDCA/g/hr when measured over 30 minutes.

It is provided a process for producing lactosucrose from a source of lactose such as whey permeate and a source of sucrose as well as a source of both lactose/sucrose such as chocolate milk to enzymatically generating in situ lactosucrose, and fructosylate phenolic compounds contained therein, the process comprising contacting the dairy starting material (containing sucrose) with a levansucrase (LS), which can be immobilized on a solid support, selected from Bacillus amyloliquefaciens (ATCC 23350), Gluconobacter oxydans (strain 621H) (LS1), Vibrio natriegens NBRC 15636 (LS2), Novosphingobium aromaticivorans (LS3), and Burkholderia graminis C4D1M (LS4), or a combination thereof.

The present invention relates to encapsulation of microbial cultures to improve the robustness and stability upon storage. In particular, the present invention relates to dry preparations of microbial cultures, such as lactic acid bacteria (LAB), coated by a fat-matrix that increase survivability and mitigate post-acidification upon storage at ambient temperature for extended periods of time.
