The effectiveness of acidity and supplementation with different concentration of sodium chloride salt on function properties for whey protein powder prepared from salted and unsalted whey were investigated. The resultant whey protein powder was in a denatured form and contained about 50% protein. Whey protein powder from salted whey was generally more water soluble at any particular pH values (...

In the current study, the relationships between functional properties and average molecular weight (AMW) of collagen hydrolysates from Spanish mackerel (Scomberomorous niphonius) skin were researched. Seven hydrolysate fractions (5.04 ≤ AMW ≤ 47.82 kDa) from collagen of Spanish mackerel skin were obtained through the processes of acid extraction, proteolysis, and fractionation using gel filtrat...

Lipid based drug delivery systems, and in particular self-emulsifying drug delivery systems (SEDDS), show great potential for enhancing oral bioavailability but have not been broadly applied, largely due to lack of general formulation guidance. To help understand how formulation design influences physicochemical emulsion properties and associated function in the gastrointestinal environment, a ...

Two Bacillus strains capable of emulsifying immiscible organophosphorus pesticides were isolated by enrichment methods. The emulsifying factor produced by Bacillus strain FE-2 has a high molecular weight, is Iysozyme sensitive and thermostable, and can be precipitated with trichloroacetic acid or ammonium sulfate; it may be a glycolipopeptide. It is specific for immiscible organophosphorus pest...

Emulsion type is often related to the preferential solubility of the emulsifying agent in one of the Phases (Bancroft rule). Recently, however, emulsion type has been interpreted quantitatively, though purely empirically, according to the hydrophilic-lipophilic balance (HLB) classification. The relation of HLB numbers to the solubility of the emulsifying agent in the oil or water phases is disc...

Efavirenz is a drug with an absorption window. Its oral bioavailability is 40-50%. The aim of this work was to formulate solid self-emulsifying drug delivery system to improve the solubility and bioavailability of efavirenz. Solubility of Efavirenz was determined in various vehicles like oils, surfactants and co surfactants. Which, upon dilution with aqueous media, spontaneously form fine oil i...
