What is capsicum oleoresin?
Oleoresin Paprika is a liquid or oil pigment additive that adds deep red color to food. It is a natural food pigment extracted from chili peppers and processed from liquid or fat. As a common food colorant, it is often used in the production of sausages, condiments and snack foods.
Capsicum oleoresin is also called capsicum extract, capsicum oil, and capsicum essential oil. It is a mixture containing many substances, mainly composed of capsicum pigments and spicy substances. Its representatives are capsanthin, capsorubin, capsanthin, zeaxanthin, violaxanthin, capsanthin diacetate, capsanthin palmitate, etc.; spicy substances include capsaicin , capsaicinol, dihydrocapsaicin, nordihydrocapsaicin, etc.
Chemical composition of capsicum oleoresin
Capsicum oleoresin is a mixture, including capsicum essential oil resin and capsicum red oleoresin. Capsicum essential oil resin is where the spiciness lies in capsicum oleoresin. Capsicum red oleoresin is not spicy and is blood red.
Pure capsanthin can be obtained by precipitating shiny needle-like crystals from petroleum ether, with a melting point of 181 to 182°C. The maximum absorbed light wave is 483nm, and the optical rotation [α]cd+36º (in chloroform). Soluble in acetone and chloroform; also easily soluble in methanol, ethanol, ether, and benzene; slightly soluble in petroleum ether and carbon disulfide; insoluble in water and glycerol but soluble in most non-volatile oils. Resistant to heat, acid and alkali. It can fade when exposed to Fe3+, Cu2+, Co2+, etc.; it can form a precipitate when exposed to Pb3+.
For example, as a crude product, it often contains about 50% capsanthin, about 8.3% capsorubin, about 14% zeaxanthin, about 13.9% β-carotene, about 5.5% cryptocapsaicin, etc. Its Scoville Heat units range from 100,000 to 2,000,000. Residual solvent ≤0.003%, heavy metal (calculated as Pb) ≤0.002%. Partially soluble in ethanol, but soluble in most non-volatile oils (or edible oils).
Material uses of chili oil
1. It can be used as seasoning, coloring, flavoring agent and fitness aid in the food industry. It can also be used as a raw material to make other complexes or single preparations. At present, pepper extract is also processed into water-dispersible preparations on the market to expand its application range.
2. The most common unique use is to add it to poultry feed to make egg yolks darker than their natural color. Because the pigments are extracted from natural foods, they do not need to be certified by the Food and Drug Administration in the United States. It is also treated loosely in the EU, grouped with similar colorants such as paprika and capsanthin.
The difference between capsicum oleoresin and capsicum red
Capsicum oleoresin: also known as capsicum extract, capsicum oil, capsicum essential oil. It is a mixture containing many substances, mainly composed of capsicum pigments and spicy substances. .
Capsicum red pigment: Also known as capsicum red, it is a tetraterpenoid orange-red pigment that exists in mature red pepper fruits and belongs to the carotenoid pigments. Among them, the more polar red components are capsanthin and capsorubin, accounting for 50% to 60% of the total, and the other is the less polar yellow component, whose main components are carotene and zea yellow. quality, they have vitamin A activity.
Capsicum red pigment not only has bright color, high color price, strong tinting power and good color retention effect, it is widely used in the coloring of aquatic products, meat, pastries, salads, cans, beverages and other types of food. It can also effectively prolong the life of simulated food. It has a long shelf life; it is also highly safe, has nutritional and health care functions, and has been proven by modern science to have anti-cancer, anti-radiation and other functions, and has good development prospects.
After reading the above article, do you have a new understanding of food safety? However, there are many additives on the market that replace natural chili peppers. Regular consumption will have certain effects on the body. You need to be careful when going out for food.
