Advances in processing, encapsulation, and analysis of food flavor compounds

In recent years, the market for edible flavor has become larger and the demand for edible flavor has become more diverse. Customers are paying more attention to natural, healthy, and functional flavors. This article reviews some new technologies about flavors in recent years, including processing technology, encapsulation, and detection of flavors. The synthetic technologies of flavor include thermal reaction technology, enzymatic hydrolysis technology, and microbial fermentation technology. The encapsulation technology includes nano-emulsion and filled soluble hydrogel, as well as the new carrier materials used in packaging, such as & beta;-cyclodextrin, 2-acetyl-1-pyrroline (2AP), yeast cell, and jackfruit seed starch (JM) are also hot spots in recent years. Finally, the detection of flavor components and the monitoring of characteristic flavor substances and harmful flavor substances are very important for flavor quality control. There are many detection techniques, such as chromatographic analysis techniques, solid-phase microextraction, electronic nose and electronic tongue, sensor arrays, and fluorescence detection with DNA barcoding techniques and (quantitative) conformational relationships.
