The recent growing concern driven by consumer interest in the safety and quality of seafood, has boosted the search for healthy and functional aquafeeds. The current study represents the first approach to assess the potential of volatile composition of the wine industry by products (e.g., grape pomace, grape stems, lees), as additives for improving the quality of fish feeds in terms of organoleptic characteristics (e.g., aroma and flavor) and health benefits. Headspace solid-phase microextraction followed by gas chromatog.-mass spectrometry (HS-SPME/GC-MS) was used to establish the volatile profile of wine industry byproducts. A total of 153 volatile organic compounds (VOCs), which belong to different chem. families, comprising 36 esters, 31 carbonyl compound, 20 alcs., 18 terpenoids, 17 acids, 11 furanic compounds, four volatile phenols, two lactones, and 14 miscellaneous, were identified. Esters and terpenoids showed a pos. contribution to the aquafeeds aroma with fruity, sweet, green, fresh, and berry notes, whereas some acids (e.g., hexanoic acid) and terpenoids (e.g., limonene) could be used as antimicrobial, antioxidant and antiproliferative agents. Our findings confirmed the potential of wine industry byproducts as a rich source of essential compounds to enhance the quality of aquafeeds towards the valorization of winery waste based on the concept of circular economy. Further investigation on the extraction, isolation and purification of VOCs from a natural bio-source will guarantee the safety of the aquafeed and compliance with the requirements of the animal feed industry. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Quality Control of Isopentyl hexanoate).
Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Quality Control of Isopentyl hexanoate
