Durian fruit is well-known for its strong aroma due to the presence of esters and sulfur compounds Although the usage of durian husk as a deodorizing agent of durian aroma has been a known practice, there is a lack of scientific evidence. Here, we investigated the effect of using durian stalk extract to deodorize durian aroma. Static-headspace gas chromatog.-mass spectrometry technique is used to semi-quant. track the variation of 13 esters and sulfur compounds found in durian. Durian stalk extract reduced the amount of esters and sulfur compounds in headspace up to 45 and 55%, resp. NaCl, CaCl2, and Na2SO4 provided a similar effect on sulfur compounds In addition, lemon and ginger extracts were evaluated and the latter performed as well as durian stalk extract This study has implications for the application of durian husk as a biomass feedstock for the development of plant-based deodorizers. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Category: esters-buliding-blocks).
Methyl2-methylbutyrate (cas: 868-57-5) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Category: esters-buliding-blocks
