“…In terms of the nutritional value of cereal lipids, the importance is well recognized of the relative high content of polyunsaturated fatty acids (PUFA) with different chain lengths, present in free form (free fatty acids) and the acylated forms of triacylglycerols (TAG), diacylglycerols (DAG) and, in relative minor amounts, the monoacylglycerols (MAG). As DAG and MAG, the presence of polyunsaturated sterol esters (SE), as well as sterols and stanols, reveals the high nutritional value of cereals [12,[14][15][16][17][18][19][20]. The extraction methods employed affect the quality of the resulting oil.…”

Cereals have been one of the major food resources for human diets and animal feed for thousands of years, and a large quantity of by-products is generated throughout the entire processing food chain, from farm to fork. These by-products mostly consist of the germ and outer layers (bran) derived from dry and wet milling of the grains, of the brewers’ spent grain generated in the brewing industry, or comprise other types obtained from the breadmaking and starch production industries. Cereal processing by-products are an excellent low-cost source of various compounds such as dietary fibres, proteins, carbohydrates and sugars, minerals and antioxidants (such as polyphenols and vitamins), among others. Often, they are downgraded and end up as waste or, in the best case, are used as animal feed or fertilizers. With the increase in world population coupled with the growing awareness about environmental sustainability and healthy life-styles and well-being, the interest of the industry and the global market to provide novel, sustainable and innovative solutions for the management of cereal-based by-products is also growing rapidly. In that respect, these promising materials can be valorised by applying various biotechnological techniques, thus leading to numerous economic and environmental advantages as well as important opportunities towards new product development (NPD) in the food and feed industry and other types such as chemical, packaging, nutraceutical (dietary supplements and food additives), cosmetic and pharmaceutical industries. This review aims at giving a scientific overview of the potential and the latest advances on the valorisation of cereal-based by-products and wastes. We intended it to be a reference document for scientists, technicians and all those chasing new research topics and opportunities to explore cereal-based by-products through a circular economy approach.

“…However, information on GC‐MS analysis of VOCs in pearl millet is scanty (Khan, 2017). Previous studies indicate the execution of GC‐MS analysis along with multivariate data analytical techniques, such as principal component analysis (PCA) and partial least square discriminant analysis (PLS‐DA), for the classification of VOCs in various cereal grains (Gao et al, 2021; Olsson et al, 2002; Pastor et al, 2020). Furthermore, assessing the VOCs by identifying the functional group also helps us know the extent of degradation in the stored products.…”

Background and ObjectivesVolatile organic compounds (VOCs) are considered biomarkers for the metabolic activities of biological entities. This work analyzed the impact of storage period and temperature (5°C, 25°C, and 45°C) on the VOC profile of pearl millet grains stored for 120 days through headspace gas analysis using solid‐phase microextraction–gas chromatography–mass spectroscopy (SPME‐GC‐MS).FindingsThe major groups identified in the pearl millet grains belonged to acid, alcohol, aldehyde, alkane, and ester groups. VOC data were analyzed using principal component analysis, partial least square discriminant analysis (PLS‐DA), cluster heat map, and network analysis of metabolite–metabolite interactions. The PLS‐DA could distinctly classify the VOCs generated with respect to different storage conditions. The VOCs generated during storage indicated the four most significant metabolic pathways, that is, fatty acid biosynthesis, cutin, suberine and wax biosynthesis, arginine biosynthesis, and arginine and proline metabolism.ConclusionsThe SPME‐GC‐MS protocol developed for mapping VOC through this study and the classification protocol developed can be used for developing quality monitoring systems in pearl millet grains.Significance and NoveltyIdentification of VOCs at a particular period will be helpful for the recommendation of appropriate remedial measures at the right time to avoid the spoilage of grains.
