Papaya (Carica papaya L.) fruit are consumed worldwide, but they are highly perishable. The effects of the application of 1-methylcyclopropene (1-MCP) with and without ethylene on ‘Golden’ papaya ripening and production of volatile compounds responsible for aroma. Fruit were treated with 2.5 μl L-1 ethylene and/or 100 nL L-1 of 1-MCP for 12 h as follows: I) control, II) ethylene, III) 1-MCP, IV) ethylene + 1-MCP (simultaneous), V) ethylene followed by application of 1-MCP at a 12 h interval and VI) ethylene + 1-MCP without any interval. Pulp firmness, skin color, skin chlorophyll content, skin and pulp carotenoids, ethylene production, respiratory activity, internal ethylene concentration (IEC), pectin Me esterase (PME) activity, 1-carboxylic acid-1-aminocyclopropane oxidase (ACC oxidase) activity and volatile compounds were measured. Fruit were stored at 22 °C, with anal. of volatile compounds performed until day 8 and all others until day 6. Fruit treated with only 1-MCP developed rubberized pulp. Fruit treated simultaneously with ethylene and 1-MCP reached desirable firmness for consumption by day 6. Co-application of 1-MCP + ethylene promoted chlorophyll degradation A consistent increase in ethylene production in 1-MCP-treated fruit above those observed in control fruit and in fruit treated with ethylene only was observed In relation to volatile compounds, linalool and its oxides were affected less by 1-MCP treatment, with or without ethylene, on days 2 and 6, and did not affect fruit flavor. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Application of 106-73-0).
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. 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.Application of 106-73-0
