Abstract: The invention provides a process for the preparation of an edible emulsion having a reduced oxidative metal content which comprises an oil phase and an aqueous phase, the process comprising the steps of (a) providing a starting material containing a protein material; (b) removing metal from the starting material; and (c) using the product of step (b) to form an edible emulsion. An edible emulsion obtainable by such a process and a food product comprising such an edible emulsion are also provided.

Abstract: The invention relates to a process for the preparation of a food product comprising the steps of: (a) preparing a mixture comprising protein and water; (b) adjusting the pH of the mixture to a value within the range of 2.0-11.0; (c) pre-incubating the mixture; (d) subjecting the mixture to a sonication treatment or a high shear mixing treatment; (e) optionally, separating the product of step (d) in a fraction rich in gas microbubbles and a fraction poor in gas microbubbles; (f) drying the mixture and/or fraction comprising protein coated gas microbubbles until dried protein coated gas microbubbles are obtained; (g) using the dried protein coated gas microbubbles in part or in whole as a food ingredient and (h) finishing the preparation of the food product.

Abstract: A food product is described comprising an aqueous phase and gas microbubbles substantially dispersed in the aqueous phase which gas microbubbles have coating and a mean diameter size distribution with a maximum below 10 &mgr;m, wherein the coating substantially consists of protein, wherein the pH of the aqueous phase is from 2.5 to 6.0.

Abstract: A method of inducing the formation of color determining compounds in a tea-based food product, characterized in that the tea leaves are treated with an exogenous laccase, polyphenol oxidase or peroxidase, in combination with a pretreatment with a tannase. Also, a treatment with a fungal laccase form a Pleurotus species can be performed to enhance the color of a tea-based product.
