Fruits and vegetables contain a large number of volatile compounds, which constitute their unique odor and contribute to their flavor. However, there are only a few key aroma compounds that contribute to the special aroma. How to screen and identify key aroma compounds from many non-contributing and low-contributing compounds has always been the focus and difficulty of the research on the flavor quality of fruits and vegetables. However, it could be better solved via molecular sensory science technology. This review summarizes the application of molecular sensory science technology in fruits and vegetables flavor in recent years, and elaborates the analysis methods related to molecular sensory science, such as sensory evaluation, GC×GC-MS,GC-IMS, GC-O, OAV, omission test and recombination experiment. And some problems existing in current molecular sensory science technology are discussed and prospected.

Description of the subject. Current trends suggest an increasing future demand for conventional meats, which indicates a strong need to shift this dependency to other alternative protein sources such as insects. Literature. From a nutritional point of view, of all the insects consumed globally, grasshoppers are particularly important as a human food. Data from the literature regarding the nutrient composition, amino acid profile, fatty acid profile, mineral composition and vitamin content of grasshoppers as reviewed in this paper, suggest that a number of grasshopper species are a good source of nutrients. It also highlights some of the health related aspects that might arise from the consumption of grasshoppers, mostly linked to agricultural practices and the allergic response of sensitive individuals. The paper also summarizes some religious, social and economic factors that are associated with grasshopper consumption. Conclusions. The success of introducing grasshoppers as a novel food in western countries depends on changes in consumer attitudes. It would be interesting to develop food products derived from grasshoppers in a form acceptable to consumers. Furthermore, it is important to explore the food potential of some grasshopper species native to western countries and to develop their rearing methodologies to enhance availability.
