Disclosed herein is an extrudate comprising a yeast material wherein the yeast material constitutes between 35% and 100% by dry weight of the extrudate. Further, compositions and food products comprising same are disclosed. Further methods for improving the flavor of a yeast material, by adjusting its pH are also disclosed.

The subject invention provides improved methods for producing fatty acid esters using yeast not previously known to produce fatty acid esters. In particular, Meyerozyma spp. can be cultivated under specially-tailored conditions such that the yeast produces a variety of fatty acid esters. A yeast culture and fermentation compositions are also provided, comprising yeast cells, liquid growth medium, and a high concentration of growth by-products, such as fatty acid esters.

A traditional Chinese medicine polysaccharide extract freeze-drying protective agent, a direct-to-vat starter and preparation methods thereof are disclosed, which belong to the technical field of feed starter. The compound traditional Chinese medicine polysaccharide extract freeze-drying protective agent includes Poria cocos polysaccharide extract, Atractylodes macrocephala polysaccharide extract, Radix codonopsis polysaccharide extract, L-tyrosine, α-cyclodextrin and polyethyleneimine. Its application in the freeze-drying protection of direct-to-vat starter of aquatic fermentation feed can reduce the damage to the cells caused by freeze-drying, improve the survival rate of the cells in the starter after freeze-drying, effectively prolong the storage period of the starter, and ensure that the fermentation activity remains at a high level during storage.
