Disclosed herein is a method for producing prune juice concentrate. By the such method of the invention, a production of prune juice concentrate with low acidity and low cost is achieved by using sweet plum varieties such as President, Stanley, Sugar, and Uryani with high purity.

This invention relates to a process of preparing a concentrated liquid foodstuff comprising treating a sugar solution or a concentrate or an extract having a Brix of more than 20, with carbohydrate oxidase and catalase without adjusting the pH before or during the treatment by addition of buffering substances or basic substances, to obtain a concentrated liquid foodstuff, wherein the final pH is lower than 3.

An oat based vegetable health drink comprises or substantially consists of carbohydrate of high glycemic index (GI) from oats, inherent oat protein, -glucan, potato protein or other protein of vegetable origin of a composition similar to that of potato protein, and water but does not contain any of: protein of animal origin, trimethylglycine, hydrocolloid other than -glucan. Also disclosed is a method of promoting muscle glycogen recovery upon physical exertion by administration of a glycogen recovery efficient amount of the health drink in close timely proximity of the exertion.

The present invention relates to the use of a cysteine endoprotease or a malt extract to prevent or reduce the cloudiness of a cereal-based beverage, fermented or not.

The present invention provides a method to convert the intrinsic sugar of a juice into indigestible oligosaccharides (such as, low-polymerization fructose and sorbitol). The present method comprises using a Zymomonas mobilis biomass and fructosyltransferase as well as pressure treatment. Taking advantage of the present method, the drawbacks of drinking juices, such as too many sugar and calorie intake can be obviated, and thereby the present invention can offer healthier option to the consumers.
