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.
