Special Issue Information

Dear Colleagues,

It is well known that lipids are multifunctional components that influence chemical-physical and organoleptic properties, such as the nutritive and healthy value of foods. Due to the heterogeneity of compounds and the multiplicity of molecular species of acyl constituents, lipid analysis has always been a challenge for food chemists. Analytical methodologies have greatly evolved over the past decades, moving towards techniques that are able to study at a molecular level the composition of food lipids. This approach allows one to define specific fingerprints, which are valuable to assess the nutritional and healthy properties, as well as the authenticity, of foods. Knowledge about the structural characteristics of lipids may allow the development of tailor-made products designed for a particular function or application. To this end, dietary lipids are the subject of ongoing research in relation to chemical and enzymatic processes for obtaining specific lipid compounds.

This Special Issue encourages the submission of original research or reviews of scientific literature addressing recent advances in analytical methodologies to measure lipid properties and in processing methods to obtain high-quality lipids.

Papers should focus on (a) the development of new analytical approaches to characterize food lipids, (b) the evaluation of their quality and functional properties, (c) innovative approaches to improve the quality and nutritional value of foods lipids, and (d) the development of new functional foods or nutraceuticals.

Hemp seed oil (HSO) has received considerable attention for its health properties, especially due to unsaturated fatty acid (UFA) content. In this work, the triacylglycerol (TAG) fraction of Italian and Extra-European HSO was characterized by applying an enzymatic approach, based on the use of pancreatic lipase and sn-1,2-diacylglycerol kinase. This procedure allows determination of the intrapositional FA% composition of TAG. The results of the stereospecific analysis are useful for deepening knowledge on HSO nutritional aspects. The high percentage of UFA (88.3–89.9%), in particular essential FA (74.4–85.9%), of HSO samples in sn-2 position is important for long-term health effects, but also to enhance the use of this oil as a functional ingredient in food, cosmetic and nutraceutical fields. Furthermore, the results of total and intrapositional FA % compositions, subjected to principal component analysis, were able to differentiate HSO Italian samples from Extra-European ones. Based on the obtained results, it can be stated that the stereospecific analysis represents a potent analytical tool providing the fingerprint of TAG fraction, useful to highlight possible chemical descriptors for HSO authenticity and traceability purposes.

A wheat bran oily extract obtained with supercritical carbon dioxide at 25.0 ± 0.1 MPa and 40 ± 2 °C has been analyzed in order to determine some valuable bioactive compounds as alkylresorcinols, α-linolenic acid, steryl ferulates, tocopherols and phenolic compounds, which levels were around 47, 37, 18, 7 and 0.025 mg/g oily extract, respectively. To our knowledge, this is the first time that the presence of steryl ferulates has been observed in a supercritical fluid extract of wheat bran and that γ-tocopherol has been described in wheat bran oily extracts. Other common quality parameters, directly correlated with oxidative degradation, were also evaluated. Acidity values around 15% oleic acid were detected, while low levels of hydroperoxides (around 2.4 meq O2/kg) and very low levels of hexanal (0.21 ppb) were found. Composition of the wheat bran oily extract was stable during 155 days of storage at 21 °C and darkness, and only a slight decrease in alkylresorcinols and tocopherols contents (13% and 20%, respectively) was observed. These results indicated an attractive potential of the obtained oily extract for industrial applications as food ingredients, nutraceuticals, and others. Full article
