Heat-treated, shelf-stable liquid nutritional compositions comprising whey protein and non-whey protein, and methods of producing and using these compositions. The compositions have a pH of from about 6.0 to about 8.0, a total protein content of at least about 6 g per 100 mL of the composition. The whey protein comprises or is provided by an ingredient that comprises heat-denaturable protein of which at least about 55% is present in a denatured state, and the non-whey protein comprises or consists of casein, or one or more non-dairy proteins, or casein and one or more non-dairy proteins.

Provided are a beverage composition comprising: chlorophyll-deficient Chlorella; a specific gum as a stabilizer; and an aqueous liquid medium and a process for preparing the same, wherein the beverage composition exhibits excellent dispersion stability without precipitation, and prevent the browning phenomenon occurring in a sterilization process.

A heat-sterilized packaged beverage containing ascorbic acid in an amount of 6 mg/100 ml or more and having a ratio of the amount of ascorbic acid to the amount of a medium-chain fatty acid triglyceride (ascorbic acid/medium-chain fatty acid triglyceride) of 0.0003-0.1340 inclusive, to which 1 mg/100 ml or more of catechins (the total amount of catechin, catechin gallate, epicatechin, epicatechin gallate, galocatechin, galocatechin gallate, epigalocatechin and epigalocatechingalate) are added. Thus, an unpleasant smell like deteriorated rice bran, said smell being generated during the storage of the heat-sterilized packaged beverage that contains ascorbic acid and the medium-chain fatty acid triglyceride within the range as specified above, is reduced.

The group of inventions relates to the food industry, namely, to a method and device for processing brewer's spent grains. The invention makes it possible to obtain a gluten-free protein drink with a protein content of at least 10.0 wt. % dry weight. The principle of the invention is based on the technology of preparing brewer's spent grains for the extraction of nutrients and their extraction by mechanical processing on the proposed industrial line. The essence of the method lies in the fact that brewer's spent grains are loosened on a vibrating screen, crushed in a colloid mill, with the addition of water in a ratio of 0.5:1 to 1:1 with respect to the grains, to obtain a paste-like homogeneous mass, and then this mass is processed in a screw extractor for further grinding and separation into 2 fractions, namely: a suspension with a water content of 90-95%, which all nutrients remain in, including the proteins of the brewer's spent grains, and crushed husks of the brewer's spent grains with a water content of 60-75% suitable for further industrial use. Then, the suspension is subjected to removing suspended particles to obtain the final product—vegetable milk (protein drink), which is pumped into a storage tank.

Aseptic beverage products are prepared by mixing beverage ingredients together. The beverage ingredients include a protein source, such as a milk protein concentrate, and at least one buffering agent, with the at least one buffering agent including baking soda. Preferably, the at least one buffering agent further includes lemon juice concentrate. The pH of the beverage ingredients is adjusted to a level between 6.7 and 7.0 using the at least one buffering agent. The beverage ingredients are then heated to at least 139° C., and the at least one buffering agent prevents precipitation of the protein source during heating. Afterwards, the beverage ingredients are packaged as a plurality of aseptic beverage products.
