| Abstract | This research aimed to use etherification to extract carboxymethyl cellulose (CMC) from the rind of durian fruits to coat mango fruits (Mangifera indica Linn.) cv. Namdokmai Sri Tong and maintain their quality. The process involved extracting cellulose in a base and using hydrogen peroxide for bleaching. Monochloroacetic acid (MCA) was used to react with the extracted cellulose. The results found that the suitable conditions for preparing CMC were 20.0 percent sodium hydroxide (NaOH) and 10.0 grams of MCA. The substitution degree (DS) was 0.12.The characteristic analysis of the extracted CMC was identified using a Fourier transform infrared spectroscopy. It was found that the functional group, importantly, corresponds to commercial CMC. The obtained CMC sheet can completely degrade using soil embedding methods within 60 hours. The water vapor permeability (WVP) test results showed that CMC and glycerol affected the film properties. Increasing CMC content, water vapor permeability (WVP) of the film decreased. While increasing the amount of glycerol will cause increased water vapor permeability because glycerol has the property of being a moisture absorbent. The appropriate ratio of CMC and glycerol was 3 %w/v of CMC and the glycerol content was 0.25 %w/v. The prepared CMC can be applied as the mango fruits (Mangifera indica Linn.) cv. Namdokmai Sri Tong coating film to extend the shelf life. |
