Effects of modified atmosphere and sugar immersion on physiology and quality of fresh-cut ‘Braeburn’ apples was written by Rux, G.;Bohne, K.;Huyskens-Keil, S.;Ulrichs, Ch.;Hassenberg, K.;Herppich, W. B.. And the article was included in Food Packaging and Shelf Life in 2021.Safety of Methyl2-methylbutyrate This article mentions the following:
Fresh-cut fruits are highly perishable and show a short shelf life. Therefore, storage in sugar syrup is com. used to delay undesirable metabolic changes and to prevent browning. Investigations on the effects of syrup application on volatile organic compounds (VOCs), important for the consumers’ acceptance, are rare. It is, however, known that low O2 availability, as found in fruit slices after immersion, may result in the formation of unwanted off-odor. This neg. affects the sensory quality of fresh-cuts. In the present study, fresh-cut ‘Braeburn’ apples were comparatively stored in air, in three modified atmospheres (O2: 10, 5 and approx. 0%; CO2: 10, 15 and 20%) or in sugar syrup (20% sugar content). Relevant quality, physiol. and microbiol. parameters were evaluated on days 3, 6 and 10 of storage. Particular focus was laid on the evaluation of VOC emission to indicate biosynthetic responses that affect aroma-relevant VOCs. Atm. storage of apple slices, among others, increased the emission of Et acetate, which may create off-odor and neg. affects the customers’ acceptance. In contrast, syrup-immersion of apple slices resulted in a pronounced loss of aroma but prevented the occurrence of off-odor. The results indicated metabolic changes, which were independent of O2 availability. High CO2 or VOCs concentrations in the fruit tissue may inhibit esterification or may induce a feedback inhibition of VOC synthesis. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Safety of Methyl2-methylbutyrate).
Methyl2-methylbutyrate (cas: 868-57-5) 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. Polyesters are important plastics, with monomers linked by ester moieties. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Safety of Methyl2-methylbutyrate
