Abstract: Improved comestibles including foods and drugs are provided, incorporating parenchymal cell cellulose. Improved properties, including physicochemical, rheological and nutritional properties result from such incorporation. Stabilized dispersions, emulsions, foams and frozen materials can preferably be provided through employment of the preferred embodiments.

Abstract: Heat-gellable protein isolates are described which are capable of forming heat set gels of hardness values comparable to or exceeding that of egg white at the same dispersion concentration. The isolate is formed by manipulating the pH and ionic strength conditions of aqueous dispersion of a substantially undenatured vegetable protein isolate to provide an ionic strength greater than 0.2 and a pH up to about 6.0.

Abstract: A substantially undenatured protein isolate is formed from certain legumes and oil seeds, typically rapeseed (canola), by extracting protein from the source material with water and then diluting the resulting protein solution with more water. The dilution forms a dispersion of protein aggregates which are settled from the dispersion.

Abstract: A novel protein isolate is described. The isolate is substantially undenatured, has substantially no lysinoaniline content and substantially the same lysine content as the protein source material from which it is derived. The isolate has substantially no lipid content and takes the form of an amorphous, viscous, sticky, gluten-like protein mass, or a dried form of the mass. The amorphous protein mass is formed by settling an aqueous dispersion of protein micelles consisting of homogeneous amphiphilic protein moieties. The aqueous dispersion is formed from the source protein, usually a plant protein, preferably by a salting-in and dilution-out procedure. The protein isolate exhibits high functionality and may be used as an egg white or wheat gluten substitute in a variety of food products.

Abstract: Proteins of high functionality and in substantially undenatured form are isolated in high yield from protein sources by extraction of the protein from the source material using a food grade salt solution under controlled conditions, increasing the protein concentration of the resultant extract while maintaining the same salt concentration, and diluting the concentrated protein solution. Protein isolate in the form of protein micelles forms in the aqueous phase and settles to an amorphous sticky, gluten-like protein mass, which may be dried to powder form.

Abstract: Proteins from a wide variety of sources--typically, starchy legumes, starchy cereals, and oilseeds--are extracted and recovered with gentle aqueous conditions which do not employ extremes of alkali, acid, or temperature. The ionic environment of these proteins is manipulated to firstly produce high solubility (salting-in) followed secondly by ionic strength reduction to cause the proteins to precipitate by a hydrophobic-out mechanism. This process results in the formation of novel proteinaceous products, referred to as protein micelles. The protein micellation process offers a new method for preparing protein isolates with conventional and non-conventional functionalities.
