[Problems] The object of the invention is to provide a process for producing fermented milk having a satisfactory level of harness and smooth texture. [Means of solving the problems] It is found that fermented milk having a satisfactory level of hardness as well as extremely smooth texture can be produced by deoxidizing (deaerating) a yogurt mix, subjecting the deoxidized (deaerated) product to an UHT processing, and then fermenting the resulting product. Specifically disclosed is a process for producing a fermented milk, which comprises a first deoxygenating step for decreasing oxygen concentration in yogurt mix; a ultra high temperature sterilization step for heating the yogurt mix after the first deoxygenating step for longer than 1 second at higher than 110 degrees Celsius so as to sterilize the yogurt mix; and a fermentation step for fermenting the yogurt mix after the ultra high temperature sterilization step.

This invention provides a fermented whey preparation produced by carrying out of high-temperature sterilization of an aqueous whey protein solution having a solid content of 11 to 35% by weight and a pH value adjusted to 6.5 to 8.0, then subjecting the sterilized aqueous whey protein solution to lactic acid fermentation, and homogenizing the resultant fermentation liquor. In this case, lactose contained in the sterilized aqueous whey protein solution after the high-temperature sterilization is enzymatically degraded with lactase at a stage before the lactic acid fermentation, during the lactic acid fermentation and/or after the lactic acid fermentation to enhance sweetness. The fermented whey preparation of the present invention has a good flavor provided by imparting unique sourness produced by fermentation and natural sweetness and, at the same time, has a refreshed and invigorating flavor and further has a velvety texture. Further, the fermented whey preparation has excellent thermal stability and safety.

The present invention relates to a method for the improvement of the taste of non-perishable milk with simultaneously reduced fat content. In order for its taste to match that of pasteurized milk, it is proposed that the milk proteins found in the milk are microparticulated. The invention further relates to a method for the improvement of the taste of a protein-enriched non-perishable milk by adding a microparticulate.

A process that kills, or renders organically inactive, one-hundred percent of the bacteria and enzymes, as well as any other non-pathogenic microorganisms present in fresh squeezed citrus and non-citrus fruit juices and fruit juice blends, as well as fruit pulps, and dairy products. The process results in the aseptic packaging of one hundred percent natural juices and milk having a shelf life extending from two to three years without the need for refrigeration, and without the use of artificial preservatives of additives. The process also preserves the natural taste, colors, and odors typically found in fresh squeezed juices and juice blends, an citrus pulp. The invention additionally encompasses an industrial apparatus kills, or otherwise deactivates the enzymes, bacteria, and microorganisms that cause spoilage in perishables such as fruit juice, fruit juice blends, fruit pulp, wines, milk, chocolate milk, butter, yogurt, cultured milk products, beer, malt and oat beverages, soups, and soft drinks. The industrial apparatus is capable of large batch processes and continuous operation. The perishables treated by the industrial apparatus have shelf lives that extend from two to three years without refrigeration and preservatives. The device also preserves the original natural taste, color, odor, and flavor found in these perishables when fresh.
