What is oleoresin

On June 22, 2006, "Oleoresin" led the new trend of spices, which are essential and important auxiliary materials in the food industry and catering industry. Powdered spice is the most used one in the food industry in my country. In the processing of traditional rough processing spices, whether it is crushed by hammer type, roll type, or disc type, it will generate heat during the crushing process, which will cause the volatilization and oxidative deterioration of the active ingredients in the raw materials. Although the powdered spices are easy to process and easy to use, they have irreparable quality defects. Such as: aroma intensity and aroma quality are unstable; aroma and aroma are easy to lose and deteriorate during storage; aroma distribution in flavored products is uneven; affects the appearance of flavored products, often black or brown, brown spots; self-contained The enzyme system will produce enzyme browning; it is large in size, which will affect packaging, storage, and transportation; it is easy to contaminate and mix with impurities, dust, and even artificial adulteration. For example, bran impregnated with red pigment is mixed with chili powder, and loess is mixed with pepper powder. Adulteration has become an inevitable phenomenon after vicious price competition.

Essential oils, also known as volatile oils, are extracted from the flowers, stems, fruits and other parts of aromatic plants by steam distillation or supercritical extraction. They are mostly colorless or slightly yellowish transparent liquids. The main ingredients include terpenoids, aliphatic and aromatic compounds and other small molecules and volatile compounds, which are miscible with vegetable oils, insoluble in water, and have antibacterial effects.

Oleoresin refers to a thick resin product containing essential oils by extracting the aroma and taste components from the spice raw materials as much as possible by using an appropriate solvent, and then distilling and recovering the solvent. The main ingredients are: essential oils, spicy ingredients, pigments, resins and some non-volatile oils and polysaccharide compounds. Compared with essential oils, oleoresin has a richer aroma, a fuller taste, and has antibacterial and anti-oxidant functions. Oleoresin can greatly improve the utilization rate of effective ingredients in perfume plants. For example, when cinnamon is directly used for cooking, only 25% of the effective ingredients can be used, and it can reach more than 95% when made into oleoresin. It can be seen that essential oils and oleoresins have become important development directions for spices.
