Polyhydroxyalkanoates are microbial polyesters with different functions in nature. Due to their prosperous properties, they are also produced via different synthetic procedures and find applications in, for example, commodities, packaging, and medicine.

Cell size analysis correlates with traditional lipid extractions to give an accurate and reliable high-throughput method of lipid estimation in oleaginous yeast. Data presented shows the same strain grown in low (Condition 1, clear circles) and high (Condition 2, filled circles) nitrogen concentrations. A correlation is not seen between Nile red and lipid extractions due to issues of stain permeation.

The introduction of oleogels as saturated fat replacers in pork patties are shown to be a very promising approach to implement the tailoring of fatty acid profile of hamburgers. This is an encouraging outcome toward the tackling of obesity and cardiovascular diseases which are among the most worrying health problems worldwide.

Varietal or origins effects on composition and properties are of great commercial interest as product differentiation and for their relationship to global quality and added value of the virgin nut oils.

The optimized method for fatty acid analysis (solid arrows) in cattle hair increases the throughput compared to the existing method (dotted arrows). The higher speed and sensitivity improve the application of the hair fatty acid profile as a biomarker for energy availability in cows.

Optimal harvesting time for Grossa di Gerace, Ottobratica and Sinopolese olive cultivars and ripening index at the months of September (Sep), October (Oct) and November (Nov).

Ultrasound-assisted extraction with green solvent from canola seeds pretreated with microwaves is studied. The process is optimized using response surface with a Doehlert design and the results show a high yield of canola oil and tocopherol content, and reduction of extraction time.

Casimiroa edulis and Crataegus pubescens aqueous extracts (2%) decrease cardiac frequency, hypertrophy, and steatosis in obese rats. C. pubescens modulates cardiac fatty acid, diacylglyceride, and ceramide profile, whereas C. edulis improves the lipotoxic profile via the down-regulation of lipid synthesis genes and the up-regulation of -oxidation genes. These beneficial effects are associated with their polyphenol, saponin, alkaloid, and phytosterol profiles.

The expiration dates for fortified infant flours (FI) commercialized in low-income countries should be shortened from 36 to 12 months so as to guarantee the nutritional quality of these functional foods and to abide by the fortified infant flour legislation. The use of high barrier packaging materials must be generalized, although it is a necessary criterion but not sufficient to ensure the long-term stability of FI.

The corrosion behavior of bitter almond oil (BAO) that occurs in oil press during BAO production is studied. Crude bitter almond oil (CBAO), refined bitter almond oil (RBAO), and rapeseed oil are selected to determine the cause of corrosion and immersion tests and simulation corrosion tests are carried out. Hydrocyanic acid in CBAO is the main cause of screw oil expeller corrosion in BAO processing, and benzoic acid is a secondary cause.

A green technology is developed to produce a biolubricant, dimer fatty acid ester (DFAE) derived from C₃₆ dimer acid without the need for catalyst and organic solvent. The synthesized DFAE exhibits excellent cold flow properties (pour point and cloud point) and high viscosity index suitable for operation at extremely low temperature conditions.

This study aims at obtaining bio-based cross-linked polymers. One-pot polyesterification of methyl ricinoleate and methyl 12-hydroxystearate has been performed leading to polyesters known as estolides, which have been successfully cross-linked. The so-formed bio-based elastomers exhibit promising properties and show high thermal stability, tailored physico-mechanical properties, and good tensile strength.

Microbial cell count, water content, water activity, and degree of turbidity are determined to understand the role of turbidity and microorganisms in veiled extra virgin olive oil. Confocal laser scanning microscopy experiments permit the observation of the morphology of the solid particles dispersed inside the organic matrix and the distribution of water inside the oil samples.
