The present invention provides beverage preservative systems for use in high acid beverage products, and beverage products comprising the beverage preservative systems. The beverage preservative system prevents spoilage by microorganisms in a beverage within a sealed container for a period of at least 16 weeks. The present invention reduces or eliminates the use of conventional preservatives that pose health and/or environmental concerns. The components that make up the beverage preservative system of invention work together in a synergistic manner to reduce the amount of preservative required and so improve the inventive beverage's sensory impact over beverages having conventional preservatives.

A beverage comprising a collagen hydrolysate is disclosed. Absorption of the collagen hydrolysate in the intestinal tract can be modulated depending on the molecular weight of the collagen peptides and the presence of certain additives. The optimal concentration of 10,000 dalton collagen hydrolysate for intestinal absorption is about 8.4 g/l which does not appreciably increase even if the collagen concentration is increased to 20, 30 or even 40 g/l in the presence or absence of whey protein. In contrast, the absorption of a 2,000 Dalton collagen hydrolysate composition that does not contain additional proteins is shown to be enhanced by the addition of supplements including vitamins and/or CO.sub.2. The absorption is shown to increase with collagen concentration up to an optimal concentration of about 20 g/l. At collagen concentrations greater then about 20 g/l, the absorption of the collagen peptides remains constant, thus the percentage of collagen hydrolysate that is absorbed declines.

The combination of EGCG and a derivative of a basic amino acid has been found to be an effective anti-yeast agent in acidic food. The present invention relates to a method for controlling or preventing the growth of yeast in acidic food (i.e. with a pH between 2 and 6) comprising adding to said food a) epigallocatechin gallate (EGCG) and b) a derivative of a basic amino acid, and/or a salt thereof, as an anti-yeast agent. The present invention further relates to a composition for addition to food and to an acidic food comprising said composition.

Provided herein is a liquid concentrate composition having steviol glycosides, a stabiliser including xanthan and/or iota-carrageenan, and water. The steviol glycosides include rebaudioside M in an amount of about 800 ppm or more by total weight of the liquid concentrate composition. The pH of the liquid concentrate composition is less than about 7. Also provided herein is a method of providing a food product, a food product obtainable from the method, and a method of providing a liquid concentrate composition.
