Yeast Extract [Yeast Extract] fresh Yeast (Yeast Extract) is used as raw material, the Yeast autolyzed, isolation, filtration, concentration and enzyme solution to get a tan to brown paste. Yeast natural fragrance, soluble in water, aqueous solution with pale yellow to light brown, a clarification. Yeast extract is rich in protein, amino acids, peptides, nucleotides, B vitamins, trace elements. Main effect is added nitrogen source and provide the microbial growth of all kinds of vitamins and amino acids and growth factors. General dosage is 0.2% ~ 0.5%.
Water soluble extract yeast, pale yellow or brown powder. Have a special smell, but no corruption. A contain a variety of vitamins and bacteria growth factor protein nutrition agent. Easy deliquescence. Soluble in water into a light yellow to yellow transparent solution, in weak acid reaction, pH6.6. Biochemical research, biological medium. ,
Modern food work, also have begun to use add to waste beer yeast cell wall broken, enzymatic production of yeast extract sauce. Add lysozyme can significantly accelerate the yeast hydrolysate, conditions for temperature 50 ℃, the substrate concentration (12), pH7.0, 11 h, hydrolysis time and dosage of enzyme 15 ~ 20 u/g (by dry yeast); Add malt root nuclease can improve the flavor nucleotide content, conditions for temperature 50 ℃, pH 7.5, to extract the dosage of 5.0 ﹪ of malt root soaking liquid, heat preservation 4 h. The production of edible yeast extract can be used in meat products, household seasoning, health food, snack food, instant noodles as increase fresh agent, flavor ingredients and nutrition enhancer.
