摘要:
This invention relates to novel mutant filamentous fungi which are deficient in the gene for the corresponding aspartic proteinase. These organisms are useful production hosts in the production of heterologous polypeptides such as chymosin.
摘要:
Cheese is made continuously by flowing milk through a spiral flow path of a reactor containing an immobilized enzyme such as rennet which coagulates the milk. The spiral flow path is formed by a spirally wound microporous sheet containing the immobilized enzyme. Adjacent surfaces of the sheet are spaced apart with a spacer which can be a plurality of microporous ribs or a sheet in open net form.
摘要:
Aging of cheese is accelerated by adding during cheesemaking a composition containing preserved, partially disrupted L. casei and/or L. lactis, and a dried lipase similar to kid or calf pre-gastric lipase. The L. casei or L. lactis has been preserved by freezing, freeze drying, spray drying or fluidized bed drying. Preferably, the L. casei is ATCC 39539 and the L. lactis is ATCC 39538. The composition may optionally contain a similarly preserved and partially disrupted L. plantarum, and/or a microbial neutral protease. The composition may be added to cheese milk before adding coagulant to coagulate the milk or to curd with salt before pressing.
摘要:
An improved method for preparing a high quality cheese curd utilizing highly active proteolytic enzymes which produce an unstable coagulum if used in conventional methods of cheese making. The highly active proteolytic enzyme is added to milk and is inactivated after the protein casein has been altered sufficiently to produce a stable coagulum but before excessive hydrolysis occurs. Then a bacterial culture is incorporated therein to promote a desirable flavor and texture. Thereafter, the mixture is coagulated and the coagulum is processed in the conventional manner of preparing a finished high quality cheese product.
摘要:
Food products and systems and methods for their production involve subjecting pasteurized milk to a concentration process thereby forming liquid concentrated milk, then fermenting the liquid concentrated milk to form a fermented concentrated milk product. The fermented concentrated milk product is combined with a liquid emulsifying agent, thereby forming a food product. The food product is formed without the fermented concentrated milk product and the food product reaching a temperature of 145° F.
摘要:
Provided in the present disclosure are a milk coagulant, a method for obtaining asclepain of Asclepias Linn. and cysteine protease B of Calotropis R. Br., as well as a method of producing cheese. The milk coagulant includes at least one of the asclepain of Asclepias Linn. and the cysteine protease B of Calotropis R. Br.
摘要:
The present invention relates to a method for producing a cheese. The cheese has one or more flavour characteristics of a sheep cheese and/or a goat cheese. The method most preferably comprises mixing a milk with a coagulant, a starter culture, a strain of Yarrowia lipolytica and a strain of Kluyveromyces lactis, and wherein the milk comprises or consists of bovine milk having a milk fat content.
摘要:
The present invention is directed to a cheese product having a blue cheese flavor and appearance a method of making the same. The method includes generating a coagulum comprising whey and curd from a pasteurized milk product, cutting and stirring the coagulum to release the whey from the curd, draining the whey from the curd, forming an emulsifier, adding the emulsifier to the curd, and pressing the curd into blocks. The emulsifier is preferably formed by blending oil and a paste and heating the oil and the paste. The paste preferably includes, among other ingredients, inert Penicillium roqueforti. A preferred version of the method further includes adding black pepper and ash to the curd. The resulting cheese product, unlike blue cheese, is elastic, does not crumble, and can be sliced and shredded.
摘要:
The present invention provides a process for the preparation of a cheese, the process comprising the steps of (i) providing milk; (ii) acidifying the milk, wherein the milk is acidified with carbon dioxide to a pH of 6.2 to 6.6 when measured at a temperature of 29 to 38° C. to provide an acidified milk; (iii) inoculating the acidified milk with a starter culture, wherein the inoculation is a direct vat inoculation, to provide an inoculated acidified milk and making the cheese therefrom; wherein the inoculated acidified milk contains a coagulant, wherein the coagulant comprises at least a microbial protease coagulating agent.
