The use of lignocellulosic biomass as a raw material for the production of lipids has gained increasing attention, especially in recent years when the use of food in the production of biofuels has become a current technology. Thus, the competition for raw materials for both uses has brought the need to create technological alternatives to reduce this competition that could generate a reduction in the volume of food offered and a consequent commercial increase in the value of food. Furthermore, the use of microbial oils has been studied in many industrial branches, from the generation of renewable energy to the obtainment of several value-added products in the pharmaceutical and food industries.

The fermented beverage showed an increase in the content of phenolics, flavonoids, and antioxidant potential. The culture showed antagonistic activity against pathogens, but this result was not observed when the juice was tested.

Structured lipids (SL) containing behenic acid have been produced in order to obtain low-calorie lipids for foods; however, the development of a high nutritional value and a stable nanoemulsion carrier system for these SL is an interesting breakthrough for this field of research, improving technologic and biological potential for food application. In this sense, the aim of this study was to evaluate the stability of a nanoemulsion containing SL NeSL (produced with olive oil, soybean oil and fully hydrogenated crambe oil), the behavior during in vitro digestion and the effects on biomarkers involved in the obesity in cell models. The samples showed good stability throughout storage (30 days) under refrigeration and room temperature and after the gastric digestion phase compared to the controls (nanoemulsion of olive and soybean oil).

Brazil is the major producer of citrus, a low-cost source of hesperidin, which is a polyphenol recognized for its capacity to inhibit AGEs formation. This is the first work to evaluate the effects of a polyphenolic fraction derived from citrus wastes on the antiglycation and on the inhibition properties of digestive enzymes on the possibility to process these wastes in high value-added products.

No scientific report proves the action of the phytochemicals from the mangrove tree in the treatment of diabetes. The aim of this work is to evaluate the effects of the acetonic extract of barks (AERM) on type 2 diabetes. The main chemical constituents of the extract were analyzed by high-performance liquid chromatography (HPLC) and flow injection analysis electrospray-iontrap mass spectrometry (FIA-ESI-IT-MS/MS).

Among other blends (OC 90:10 w/w and SC 90:10 w/w), OSC (45:45:10, w/w), presented the most nutritionally interesting amounts of mono- and polyunsaturated fatty acids, as well as behenic acid.

The objective of this work was to study the anti-obesity effects of structured lipids (SL) obtained by enzymatic interesterification, based on olive oil, soy oil and fully hydrogenated crambe oil. Twenty-four C57Bl/6 mice were distributed into four experimental groups according to the diet consumed: Control Diet (CD), Structured Lipids Diet (SLD), High-fat Control Diet (HCD), High-fat Structured Lipids Diet (HSLD).
