Provided is a method for manufacturing a fermented milk product, including sequentially performing a first step of mixing raw material milk and lactic acid bacteria to obtain a mixed liquid, and a second step of fermenting the mixed liquid, characterized by performing a step of adding a Paenibacillus-derived protease to the raw material milk and/or the mixed liquid (protease addition step) before the second step is completed. According to this manufacturing method, the hardness of the fermented milk product can be adjusted to a desired value while original smoothness of the fermented milk product is maintained.

A dairy product comprising a sweetened dairy composition with a mass ratio of lactose to glucose equal to 1.0:2.7 to 2.6:1.5 and a mass ratio of lactose to galactose equal to 1.0:2.2 to 2.6:1.1. In a second aspect, a method comprises hydrolyzing lactose in the starting dairy composition in a lactase-catalyzed hydrolysis reaction and deactivating the reaction to provide a lactose percent conversion of 46 to 80 wt. %. In a third aspect, a dairy product comprises a fermented sweetened dairy composition comprising a lactose:glucose mass ratio of 0.01:2.4 to 1.0:1.0 and a lactose:galactose mass ratio of 0.01:2.7 to 1.0:1.0. In a fourth aspect, a method comprises hydrolyzing and fermenting lactose in a starting dairy composition, thereby providing a fermented sweetened dairy composition with a lactose percent conversion of 80 to 100 wt. %.

The present invention relates to a method for producing a cheese-flavored substance, including adding a bacterial cell disrupted product obtained by disrupting lactic acid bacteria and an enzyme to a milk raw material to cause a reaction. The present invention can provide a method for producing a cheese-flavored substance which can safely and efficiently produce a cheese-flavored substance having a more natural cheese flavor at low-cost with simple operation.

Methods of making a zero sugar dairy-based food product and a zero sugar dairy-based food product are provided. The dairy-based food product includes a protease, an acyl transferase, a lactase, a skim milk, at least one of an additional ingredient selected from a group consisting of a probiotic, an artificial flavoring, a natural flavoring, a cream, a vitamin, a pectin, an oil, and combinations thereof, and an amount of water. The dairy-based food product further includes a sugar content of between 0 wt % and 0.4 wt %.

The main purpose of this technique is to newly provide a technique whereby it becomes possible to shorten the time for anaerobic fermentation by reducing the concentration of oxygen contained in a raw material by a method other than an inert gas replacement method that requires the introduction of a facility. This technique provides a method for producing a fermented food or beverage, including a saccharide oxidase action step for allowing a saccharide oxidase to act on a portion or the whole of a saccharide in a raw material, and an anaerobic fermentation step for performing anaerobic fermentation. This technique also provides an oxygen concentration reducing agent for anaerobic fermentation use which contains a saccharide oxidase. This technique further provides an anaerobic fermentation method which includes a saccharide oxidase action step for allowing a saccharide oxidase to act on a portion or the whole of a saccharide in a raw material.

Acidified milk product, which has a pH of between 3.0 and 5.0 and a content of lactose of at least 1.5 mg/ml, wherein the product contains a lactase, which retains its activity at a pH of 5.0 and a temperature of 37? C. at a level of at least 5% as compared to its activity at the optimum pH of the lactase.

A method for producing a fermented food composition by fermenting a food having a class-2 food allergen, includes: adding lactic acid bacteria having leucine aminopeptidase activity of 75 or more and 720 or less units, to a food having a class-2 food allergen, and fermenting the food while adjusting a pH of a mixture including the food to 4.0 or more and less than 8.5; and enzymatically treating the resulting mixture with a metalloprotease.

The present invention relates to a method for manufacturing a strained fermented dairy product comprising the following successive steps: (a) providing a dairy product, (b) adding a lactase and a culture of bacteria comprising at least one strain of mesophilic lactic acid bacteria and at least one strain of thermophilic lactic acid bacteria and fermenting the dairy product to obtain a fermented dairy product, and (c) separating a liquid whey from the fermented dairy product to obtain a strained fermented dairy product. The present invention relates also to the use of a lactase for preventing the clogging of the separating device used in the preparation of a strained fermented dairy product.

The invention relates to a method for manufacturing a strained fermented dairy product comprising the following successive steps: (a) providing a dairy product, (b) adding a lactase and a culture of bacteria comprising at least one strain of thermophilic lactic acid bacteria, with the provision that that it does not comprise any strain of mesophilic lactic acid bacteria, and fermenting the dairy product to obtain a fermented dairy product, and (c) separating a liquid whey from the fermented dairy product to obtain a strained fermented dairy product.
