Analysis of physicochemical variables and bioactive compounds in baked sweet potato snacks.

Sweet potatoes have been the focus of study due to their nutritional content, as they are considered a food that can help reduce malnutrition owing to their energy contribution. In addition, they serve as a source of other compounds with biological activity that can offer health benefits. The objective of this research was to evaluate the effect of baking temperature on the physicochemical properties and bioactive compounds of sweet potato snacks and to analyze the kinetics for these variables during the process as a function of temperature and time.

Analysis by UPLC-DAD-ESI-MS of Phenolic Compounds and HPLC-DAD-Based Determination of Carotenoids in Noni ( Morinda citrifolia L.) Bagasse.

Noni bagasse is usually wasted after the noni juice extraction process. The purpose of this study was to investigate the phytochemical composition of noni bagasse (with and without seeds) obtained after a 1 week period of a short-term juice drip-extraction process from over-ripe noni fruit. Totals of free phenolics, flavonoids, condensed tannins, carotenoids, and most of the minerals were higher in bagasse without seeds (NSB) than in bagasse with seeds (WSB), whereas bound phenolics and total and insoluble dietary fiber were higher in WSB than in NSB.

Mechanical, physical and microstructural properties of acetylated starch-based biocomposites reinforced with acetylated sugarcane fiber.

Fiber-reinforced starch-based biocomposites provide an environmentally friendly alternative to replace petroleum-based plastics. Nevertheless, these materials present structural stability problems owing to their hydrophilicity. Therefore, a chemical modification is usually necessary.

Physicochemical and nutritional characteristics of the fruit of Zizyphus sonorensis S. Wats (Rhamnaceae).

The nanche de la costa (Zizyphus sonorensis) fruit was partially characterized by physicochemical and nutritional analyses. This fruit has a homogenous size and color and low moisture content (47 g/100 g). The content of tannins and nickel of the edible portion might limit its use.
