摘要:
In accordance with the method of the present invention for manufacture of Swiss cheese from milk, the fat level of milk is standardized to about 3.5%. The milk is subjected to membrane processing by ultrafiltration and diafiltration to provide a retentate with particular characteristics. The retentate is then fermented with a particular blend of a coccus culture and a high level of a rod culture. The usual propionic acid-forming micro-organism, such as Propionibacterium shermannii, is used. The fermentation is desirably carried out at high temperatures to achieve the results of the invention. The fermented retentate is then evaporated to a solids level desired in the finished Swiss cheese, which is generally in the range of 35% to 41% moisture. The fermented and evaporated product is suitable for packing into containers to be cured and to provide Swiss cheese without further manipulation or treatment. The particular conditions are necessary to provide the desired Swiss cheese.

The present invention relates to novel strains of Lactobacillus as well as preparations and compositions, such as fermentation broths, protective cultures, final food or feed product with Lactobacillus alone or in combination with bacteria of the genus Propionibacterium. The present invention further relates to methods for the controlling of growth of a contaminant, such as a bacteria, yeast or mould by using these novel strains of Lactobacillus.
摘要:
Swiss-type cheese flavor compositions are provided which can be used in food products for flavor addition, flavor enhancement, and as a substitute for natural Swiss cheese ingredients. It also relates to processes for rapid direct production of such cheese flavor compositions that do not require whey separation, block formation, curing or aging steps. The flavor compositions are manufactured by forming a mixture comprising a cultured milk concentrate prepared by treating milk concentrate with a lactic acid culture at a temperature of about 22 to about 45° C. for about 10 to about 240 hours, and propionic acid or an edible salt thereof. The Swiss-type cheese flavor develops after addition of propionic acid or edible salt thereof.

Pressed curd opened-body cheeses are prepared with lactic ferments including lactobacilli of the species Lactobacillus fermentum which are utilized for producing openings in the body of the cheeses. Small wheels of the cheeses may be prepared by, prior to ripening, coating the cheeses with a plastic film which is substantially impermeable to gases, alone or together with a coating layer of paraffin, or the small wheels may be prepared by ripening the cheeses in a chamber having a pressure in excess of atmospheric pressure for preventing gas loss from the cheeses.

The invention relates to a process for the recovery of whey proteins and their utilization in cheese making. Whey separated from cheese curd during normal processing is first pasteurized and then subjected to ultrafiltration to provide a whey protein concentrate, the concentrate is mixed with milk and the thus enriched milk is subjected to further ultrafiltration after which it is treated in the usual manner to form a curd.Cheese-making includes fermentation of the enriched curd product of the above process. According an alternate embodiment, the cheese-making comprises the steps of (a) curdling of the mixture of milk and whey protein concentrate and (b) ultrafiltration of the coagulum, in which case the desired cheese is directly obtained after said ultrafiltration.
摘要:
A process is provided for the manufacture of cheese and cheese like products from an edible protein-fat-salts composition which is substantially free of fermentable sugars and in which the protein and salts are capable of forming a stable matrix for the fat. Milk protein is treated with a protease to hydrolyze the protein and to develop cheese flavor components and precursors therefor. The hydrolyzed milk protein is mixed with the protein fat-salts composition and the product is made into curd which is cured in an unusually short period of time to provide cheese or cheese-like products. Butter fat may also be treated with a lipase to hydrolyze the butter fat and to develop cheese flavor components and precursors therefor. The hydrolyzed butter fat is also mixed with the protein-fat-salts composition prior to making curd.
