Apple slices (Pinova cv) dried at mild temperature (40°C), compared to 65°C dried slices, are enriched (up to about 50%) in polyphenols (e.g., catechin, epicatechin, quercetin 3-glucoside, quercetin derivatives). Chem. (dipping solutions) and phys. (packaging) treatments are key in controlling the enzymic browning of dried apple slices and maintain their nutritional content. In the present study we investigated the effects of dipping and packaging on the physicochem. properties of dried apple slices. Specifically, apple slices dried at 40°C were comparatively dipped in 1% calcium citrate (CC) or 1% citric acid (CA) and stored in active modified atm. (a-MA) or in passive (p-MA) for 100 days. A mild drying approach combined with dipping in CC and a-MA preservation, produced high quality dried apple slices, both in terms of sensory characteristics and color retention. Remarkably, upon this treatment, fruits exhibited an enhanced volatile profile that correlated with fresh and fruity apple notes. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Synthetic Route of C8H16O2).
Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. 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.Synthetic Route of C8H16O2
