Broken rice is an underutilized by-product of milling. Proteins prepared from broken rice by treatments with alkaline protease and papain have been characterized with regard to nutritional and functional properties. The protein content and the protein recovery were 56.45 and 75.45 % for alkaline protease treatment, and 65.45 and 46.32 % for papain treatment, respectively. Protease treatment inc...

This paper describes a study in which the emulsifying properties of cocoa material with and without its lipid fraction were explored. This study was motivated by the commercial interest in naturally-occurring particulate emulsifiers as opposed to the chemically modified emulsifying particles presently available for commercial use. The hypothesis was that endogenous lipids from cocoa were respon...

Introduction of the extension region of beta-conglycinin alpha' subunit at the C-terminus of proglycinin A1aB1b results in the improvement of its emulsifying properties. To understand the basic for such improvement, we introduced the alpha' and alpha extension regions to the A2B1a C-terminus, and the alpha extension and A5A4B3 hypervariable regions, and an oligopeptide composed of 20 negatively...

Composting of oiled bleaching earth with waste sludge and corn straw was carried out to investigate the ability of microorganisms to synthesize biosurfactants that might decrease the surface tension of composts. Analytical results and changes in the surface tension suggest that biodegradation of fatty by-products was the consequence of emulsifying properties of higher fatty acids. The surface t...

Three sources of food proteins were treated with microbial transglutaminase (EC 2.3.2.13) in order to assess changes in the physicochemical properties of reactivity, solubility, emulsification, and free amino groups of the formed polymers. Samples of lactic casein (LC), isolated soy protein (ISP), and hydrolysed animal protein (HAP), were incubated with the enzyme for one or two hours. LC and I...

The aim of the current study was the development of a new pellet based self-emulsifying (SE) drug delivery system for the oral delivery of poorly soluble drugs. Furthermore, we wanted to investigate the influence of physiological dilution media and enzymatic digestion on the solubilization capacity of the formulation for the model drug Progesterone. Lipid mixtures composed of Solutol HS 15 and ...

ferula gumosa  boiss is one of the natural plants of iran whose exudates (barijeh) can be used in food industry. in the present study the properties of the gum extracted from tubers of ferula gumosa were examined. for this purpose, gum was extracted from crude exudates by alcoholic extraction with 90% (v/v) ethanol. the purity of gum was relatively high, and it was composed mostly of polysaccha...
