The invention discloses a novel preparation method of cis-6-nonenal, and relates to the technical field of preparation of flavors and fragrances. According to the method, leaf alcohol is used as a raw material, self-made 1-bromo-3-hexene is used as halogenated hydrocarbon to synthesize a Grignard reagent, then the Grignard reagent and 2-(2-bromoethyl)-1, 3-dioxolane are subjected to a Grignard coupling reaction, an intermediate cis-6-nonenal diethyl acetal is generated, and then the product cis-6-nonenal is obtained through hydrolysis. The method has the advantages of high synthesis yield, no isomer in the product, high purity, simple reaction conditions, simple process route and potential industrial application prospect.

The present application relates to a kind of mint base, it is characterized in that, by weight parts, including the following components: menthone 10-20 parts;cis-3-hexenal 0-5 parts;Leaf alcohol 0-5 parts;Acetic acid leaf alcohol ester 0-1 part;Carvone 0-10 parts;Menthol 0-20 acetic acid menthyl ester 0-1 part;Mint oil 0-5 parts;Mint extract 0-20 parts.The present application only needs 7 kinds of synthetic raw materials to prepare mint essence.Make the beverage, fruit juice, syrup, jam, fermented milk, flavored milk beverage etc. beverage and other food added with this mint essence enhance the natural mint aroma of its explosive, rich in taste.

The invention discloses a volatile substance with attraction activity on tomato leaf miners in tomatoes. The volatile substance comprises any one or a mixture of four of tomato volatile matters including cis-3-hexenol (leaf alcohol), beta-phellandrene, nonanal and 4-ethylbenzaldehyde. When the volatile substances are used as a mixture, cis-3-hexenol (leaf alcohol), beta-phellandrene, nonanal and 4-ethylbenzaldehyde are mixed according to the volume ratio of 3.5: 3.8: 1: 6.7, and the volatile substances have an attractive effect on adult tomato leaf miners. A Y-type olfactometer is used for determining behavior reactions of female and male adults of the tomato leaf miner to four EAD active compounds and mixtures thereof under different concentrations, and beta-phellandrene and the mixtures with the concentration reaching 10 mu g / mu l or above have a remarkable or extremely remarkable attraction effect on the female adults of the tomato leaf miner. The highest attraction rate of the leaf alcohol to female adult tomato leaf miners can reach 76.7% and 80%, the leaf alcohol with the concentration of 100 micrograms / microliter has a remarkable attraction effect on the female adult tomato leaf miners and the male adult tomato leaf miners, and the attraction rate of the leaf alcohol to the male adult tomato leaf miners can reach 70% and 73.3%.
