Fatty acid profile of biscuits and salty snacks consumed by Brazilian college students.

High levels of biscuit and salty snack consumption have an effect on human health. This aim of this study was to determine the fatty acid (FA) composition of 19 different biscuits and 10 types of salty snacks by gas chromatography. Palmitic acid was predominant in 79% of biscuits and represented more than 55% of the total saturated fatty acids (SFAs) in salty snacks.

High hydrostatic pressure processing of tropical fruits.

Interest in the nonthermal method of high hydrostatic pressure (HHP) for food preservation has increased recently due to the possibility of inactivating microorganisms and enzymes while maintaining product sensorial and nutritional properties. This work deals with HHP use for the preservation of tropical fruit products. HHP is shown to be a practical approach to obtaining high-quality tropical fruit products that are both nutritive and safe.

Effect of high hydrostatic pressure on cashew apple (Anacardium occidentale L.) juice preservation.

High hydrostatic pressure is an alternative to thermal processing to inactivate spoilage and pathogenic microorganisms. Cashew apple juice has a pleasant flavor and is rich in vitamin C. Studies to determine the effect of high pressure on microorganisms in cashew apple juice are still lacking.

Crystal structures of bovine beta-lactoglobulin in the orthorhombic space group C222(1). Structural differences between genetic variants A and B and features of the Tanford transition.

The crystal structures of beta-lactoglobulin genetic variants A and B have been determined in the orthorhombic space group C222(1) (lattice Y) by X-ray diffraction at 2.0 A and 1.95 A resolution, respectively.

Pressure denaturation of beta-lactoglobulin. Different stabilities of isoforms A and B, and an investigation of the Tanford transition.

Beta-lactoglobulin, the main whey protein in bovine milk, exists in several isoforms of which the most abundant are isoforms A and B. We have previously reported the denaturation of beta-lactoglobulin A by hydrostatic pressure [Valente-Mesquita, V.L.
