(2) Organic pigments: azo pigments accounted for 59%, phthalocyanine pigments accounted for 24%, triarylmethane pigments accounted for 8%, special pigments accounted for 6%, polycyclic pigments accounted for 3%

29. Spices, flavors: natural spices, synthetic spices, edible spices, daily spices, other unclassified flavor;

(1) Natural flavor: animal flavor, plant flavor;

(2) Synthetic fragrances: mainly hydrocarbons, alcohols, ethers, acids, esters, lactones, aldehydes, ketones, acetals (ketones), nitriles, phenols, heterocyclic and other sulfur and nitrogen compounds;

(3) Food spices:

According to the composition of spices can be divided into monomer spices, blended spices;

According to the flavor form, it can be divided into water-soluble flavor (water flavor), but heat sensitive oil-soluble flavor (oil flavor), emulsified flavor, powder flavor;

The flavor type can be divided into citrus flavor, fruit flavor, mint flavor, bean flavor, spicy flavor, milk flavor, meat flavor, nut flavor, wine type, vegetable flavor, etc.

The composition of spices can be divided into natural spices and synthetic spices. Natural fragrances include essential oils, oleoresins, fragrance extracts, recycled fragrances, heated fragrances, fermented fragrances, and blended fragrances made from natural ingredients. Synthetic flavors refer to synthetic substances with the same chemical structure as natural ingredients, as well as aroma substances other than natural equivalents.
