Abstract:
Insoluble, denatured, heat-stable protein particles are used in food and beverage products. The particles are easily dispersible in aqueous solutions and take the form of substantially non-aggregated macro-colloids. In a hydrated state the preferred mean diameter particle size distribution of the insoluble, denatured, heat-stable particles ranges from about 0.1 microns to about 3.0 microns, with less than about 5 percent of the total number of particles exceeding about 3.0 microns in diameter. The majority of the particles are substantially spheroidal in shape and have a substantially smooth, emulsion-like organoleptic character similar to that of high-calorie fats and oils. Additionally, these particles have a degree of protein insolubility of at least about 80%, which provides processing advantages during heat treatment.

Abstract:
A whey protein with a phosphorus content reduced to 0.15 mg or less per gram of the protein, a process for the production thereof, a hydrolyzate of a highly purified low-phosphorus whey protein, and a process for the production thereof. The low-phosphorus whey protein is produced by adjusting the pH of a whey protein solution to 4 or below and bringing the solution into contact with a cation-exchange resin and an anion-exchange resin successively to thereby reduce the phosphorus content to 0.15 mg or less per gram of the protein. The hydrolyzate of the highly pure low-phosphorus whey protein is obtained by hydrolyzing the low-phosphorus whey protein with protease.
Abstract:
The present invention provides a method for the manufacture of a fat replacement material suitable for use in the manufacture of food products. The method comprises the steps of: a) providing a substantially homogeneous aqueous fluid containing albumin and at least one stabilizer selected from a sugar and salt; b) subjecting the fluid to a controlled heat treatment at a temperature and for a period of time not less and not greater than that sufficient for obtaining from 50 to 100% denaturation of the albumin; and c) spray drying of the heat treated fluid. The invention also provides a fat replacement material comprising a spray dried powder comprising an intimate admixture of 1 part by weight of from 50 to 100 % denatured albumin, and from 3 to 100 parts by weight of at least one stabilizer selected from a sugar and salt. The material of the invention has excellent emulsifying properties as well as improved heat stability and resistance to acid conditions.
Abstract:
The invention relates to a method for preparing a concentrate of denatured whey protein aggregate preferably having a mean aggregate size (median) of between 1 and 4 mu m. Said method consists of the following steps: a) an aqueous solution enriched to a maximum protein content of 4 % by weight, containing whey protein and having a pH of between 5.0 and 7.0 is thermally denatured to >/= 80 %, in relation to the protein content, under substantially non-shear conditions at a temperature of between 75 and 150 DEG C and by means of a holding period; and b) the resulting product is concentrated, preferably to a denatured whey protein concentration of between 5 and 20 %.
Abstract:
A method of producing a denatured pea protein solution comprises the steps of mixing pea protein with an alkali solvent to provide a 1-10% pea protein solution (w/v) having a pH of at least 10, resting the pea protein solution for at least 15 minutes, heating the pea protein solution under conditions sufficient to heat-denature the pea protein without causing gelation of the pea protein solution, and rapidly cooling the denatured pea protein solution to prevent gelation, wherein at least 90% of the pea protein in the denatured pea protein solution is soluble. Also described is a method of producing microparticles having a denatured pea protein matrix, the method comprising the steps of providing a denatured pea protein solution according to the invention, treating the denatured pea protein solution to form microdroplets; and cross-linking and chelating the droplets to form microparticles.
