摘要:
Process for manufacturing cheeses and other dairy products, and the resulting products, in which lactobionic acid is added, or generated in situ, in combination with a dairy component in the course of the process. The lactobionic acid can be used as the sole acidulent for direct acidification of the cheese, or in conjunction with reduced amounts of lactic acid culture. When the lactobionic acid is generated in situ during cheese manufacture according to the invention, a lactose oxidase is used in one embodiment to convert lactose intrinsically present in the dairy liquid ingredient(s) into lactobionic acid. The organoleptic attributes of the cheeses made using lactobionic acid as an ingredient are satisfactory and fully suitable. The process can be applied to the production of a wide variety of cheeses, including, for example, cream cheeses, hard cheeses such as cheddar, UF cheeses, process cheeses, cheddar cheeses, and so forth.
摘要:
The present invention relates to a method of producing a cheese-like dairy product, characterized by adding at least 10 wt %, relative to the starting material milk, of water containing Paenibacillus sp. bacteria or water that has been treated with immobilized cells of Paenibacillus sp. Bacteria into starting material milk, followed by maintaining at a prescribed temperature, separating off the curd thus formed, and performing productization with or without further maturing; a cheese-like dairy product thus produced; and a water purifier packed with a support having Paenibacillus sp. bacteria immobilized thereon and a filter medium as a packing material.

摘要:
The present invention provides a cheese curd that contains protein products originating from a dairy liquid containing casein and whey protein. In order to obtain the cheese curd, the dairy liquid is acted upon by a transglutaminase and a non-rennet protease, resulting in a substantial proportion of whey protein products being retained in the cheese curd. The invention also discloses a method of making the cheese curd that retains a substantial proportion of whey protein products. This invention further provides a cheese product, such as a soft cheese, a semi-soft cheese, or a hard cheese, that contains protein products originating from a dairy liquid containing casein and whey protein, and a method of making the cheese product.
摘要:
A process is provided for decreasing the thermal stability of Mucor microbial rennet without substantially reducing its milk-clotting activity by contacting an aqueous solution thereof with a methionine-oxidizing means under conditions effective substantially to decrease the thermal stability of the microbial rennet. The resultant treated microbial rennet is dramatically less heat stable than untreated microbial rennet and can serve as replacement for calf rennet in traditional cheese-making processes. The preferred methionine-oxidizing means is hydrogen peroxide or dye-sensitized photooxidation.
摘要:
The production of a rennin of high milk coagulating activity and low proteolytic acitivity from a selected strain of Mucor miehei which is useful in cheese making.
摘要:
A milk-clotting enzyme having proteolytic activity similar to rennin and having the ability to cleave the phenylalaninemethionine bond of a kappa-casein polypeptide chain is produced by culturing a species of Physarum polycephalum in a culture medium until a substantial quantity of milk-clotting enzyme is accumulated extracellularly in the medium, and separating the enzyme from the culture medium.
摘要:
A stabilized microbial rennet from Mucor miehei is prepared by admixing the solid enzyme product recovered from the fermentation broth with 2-3 percent of fatty acid monoesters of polyoxyethylene sorbitan.
