The application of lipids to food production is dependent on their physical, chemical, and nutritional properties. In this study, pracaxi oil, passion fruit oil, cupuassu fat, and palm stearin underwent physicochemical analyses and were combined at ratios of 40:60, 50:50, 60:40, and 70:30 to assess their potential applications in the food industry. Pracaxi oil, passion fruit oil, and cupuassu fat had interesting fatty acid profiles from a nutritional standpoint, displaying the lowest atherogenicity and thrombogenicity indices (0.02 and 0.14; 0.12 and 0.34; 0.16 and 0.65), respectively. Palm stearin had high thermal stability (7.23h). The primary applications of the blends obtained in this study are in table and functional margarine, particularly the pracaxi-stearin and passion fruit-stearin 40:60 and 50:50, pracaxi-cupuassu 60:40 and 70:30, and passion fruit-cupuassu 40:60 blends. The results suggest new industrial applications, especially for pracaxi and passion fruit oils, which are commonly applied in the cosmetic industry.
-This study evaluated the chemical composition of peeled and unpeeled green banana Cavendish (AAA) flour obtained by drying in spouted bed, aiming at adding nutritional value to food products. The bananas were sliced and crushed to obtain a paste and fed to the spouted bed dryer (12 cm height and T = 80 °C) in order to obtain flour. The flours obtained were subjected to analysis of moisture, protein, ash, carbohydrates, total starch, resistant starch, fiber. The green banana flours, mainly unpeeled, are good sources of fiber and resistant starch with an average of 21.91g/100g and 68.02g/100g respectively. The protein content was found in an average of 4.76g/100g, being classified as a low biological value protein with lysine as the first limiting amino acid. The results showed that unpeeled green banana flour obtained by spouted bed drying can be a valuable tool to add nutritional value to products in order to increase their non-digestible fraction.
The present study sought to develop lipid bases from blends between patawa oil and palm stearin. These blends were analyzed before and after the chemical interesterification process for their fatty acid and triacylglycerol composition, free fatty acid (FFA) content, peroxide index, thermal properties, melting point, consistency, and solid fat content (SFC). Blends with unsaturated fatty acid contents between 60 and 70% were obtained, with a good ratio between saturated and unsaturated fatty acids, which indicates a healthy content of fatty acids. Variations in the triacylglycerol contents and melting and crystallization thermograms evidenced the reaction. The blend with 50% stearin and 50% patawa oil showed the best results after the chemical interesterification reaction regarding the possible application in fatty products for its appropriate melting point, SFC similar to that of soft table margarines, plastic and spreadable consistency at refrigeration temperature, thus combining physical and nutritional properties desirable for the food industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
