Comparison of the effects of novel processing technologies and conventional thermal pasteurisation on the nutritional quality and aroma of Mandarin (Citrus unshiu) juice was written by Cheng, Chuan-xiang;Jia, Meng;Gui, Yao;Ma, Yaqin. And the article was included in Innovative Food Science & Emerging Technologies in 2020.Category: esters-buliding-blocks The following contents are mentioned in the article:
Conventional thermal pasteurization (90°C and 30 s), high pressure processing (HPP: 600 MPa, 4°C and 300 s), ultrasound processing (US: 50°C, 750 W and 36 min) and microwave processing (MW: 800 W, 80°C and 70 s) were evaluated by examining their effects on the sensory and nutritional qualities of mandarin juice. The treated samples had < 2 log CFU/mL total aerobic bacteria, which is equivalent to microorganism inactivation. Sugar and acid components were almost constant for all the treated mandarin juices, and no differences between treatments were perceptible. However, the mandarin juice treated with novel technologies maintained better color (L*, a* and b*), nutritional value (ascorbic acid, total phenolic, total carotenoid content and phenolic components) and aroma than the thermally pasteurized one. This study showed that US, MW and HPP are good novel processing techniques to inactivate microorganisms and maintain the sensory and nutritional quality of mandarin juice. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Category: esters-buliding-blocks).
Octyl acetate (cas: 112-14-1) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Category: esters-buliding-blocks
