ONION CONCENTRATE - Uses and synthesis methods
introduction
Onion essential oil is a brown-yellow oil. The main component is sulfur-containing compounds. Among them, allyl-containing sulfides have good anti-cancer functions, and propylene-containing disulfide has anti-platelet aggregation effect. In addition, onion essential oil also has good hypoglycemic and hypolipidemic effects. However, onion essential oil is extremely irritating, and direct consumption is more irritating to the human body, which is difficult for most consumers to accept, and the essential oil is volatile, which is not conducive to storage, which limits its further application. Therefore, it is of great significance for the application of onion essential oil to mask the pungent smell of onion essential oil by adopting a suitable method.
Main Ingredients
onion contains a special odor, mainly S-propenyl-L-cysteine sulfur oxide and dipropenyl disulfide, dipropyl disulfide, dimethyl propyl disulfide, propylene disulfide and other sulfur compounds.
source
onion is a biennial or perennial herb of liliaceae and onion genus. it is native to west Asia and has a planting history of thousands of years. it was introduced into China in the 18th century. at present, China has become the main planting area of onion and is planted all over the country. Onion is a household name vegetable with unique flavor and rich nutrition. Fresh onions contain water 86.8%, carbohydrate 11.6%, protein 1.2%, fat 0.1%, calcium 0.2%, phosphorus 0.05%, and trace elements such as vitamins, niacin, potassium, zinc, and selenium. In addition, onion also contains about 0.03% of volatile oil, which is the main component of onion's special flavor and physiological function, and is also the main direction of onion health function research.
efficacy and action
1. Bacteriostasis, through the reaction of sulfur-containing compounds with certain amino acids on the cell wall of microorganisms, prevents the normal expression of proteins, thereby inhibiting bacterial reproduction. Onion essential oil can inhibit a variety of bacteria and fungi, including Staphylococcus, Streptococcus, Vibrio and Bacillus.
2. Reduce the "three highs". Sulfur-containing amino acids and disulfide in onions can consume NADPH and enzymes necessary for cholesterol and lipid synthesis, tissue insulin is destroyed, and nitrogen compound s-methyl Cysteine sulfoxide, etc. can stimulate the beta cells of the pancreas, thereby reducing the three highs.
3. Antioxidant effect. Onion essential oil can increase the activity of catalase and superoxide dismutase, thereby enhancing the body's antioxidant stress response.
4. Anti-cancer effect. Studies have pointed out that the sulfide contained in onion essential oil can inhibit gastric cancer and esophageal cancer by regulating the metabolic enzymes of cancer factors.
application areas
onion essential oil is an obvious high-quality functional product, but its application in the food industry is relatively limited. at present, it is mainly used in the flavor and fragrance industry, and there are still many deficiencies in functional food, among which extraction method and flavor treatment are the main influencing factors.
extraction process
onion essential oil extraction methods mainly include water vapor distillation extraction, solvent extraction and supercritical carbon dioxide extraction. The water vapor extraction method is the earliest extraction method, which is easy to operate and easy to industrial production. The disadvantage of this method is that the active substance is not completely preserved and the efficiency is low. The solvent extraction method has a greater improvement than the water vapor distillation method, the extraction rate of active ingredients has been improved, and many impurity removal processes have also been added, and the process steps are more complicated. Supercritical carbon dioxide extraction is an ideal method for extracting onion essential oil. The type, yield and effectiveness of active substances are significantly improved. The method has no solvent residue, the active ingredients are preserved intact, and the natural properties are high. Since 1992, a relatively complete onion essential oil was obtained by supercritical carbon dioxide extraction, this method has gradually been favored by the market.
onion extract
Onion Oil is obtained by steam distillation after grinding the bulbs of Allium cepa L., a lily plant, with an yield of about 0.02% (fresh raw material) or 0.05% (dry material). Vegetable aromatic oils with the aroma and smell of onions, containing volatile components, taste components and pigments, etc., are used as spice for food.

main extraction method
onion oil extraction methods include: steam distillation, solution extraction, simultaneous distillation extraction, vacuum microwave-assisted extraction, supercritical carbon dioxide extraction, etc. The general extraction process requires drying, crushing, and warm soaking of fresh onions.

production method
It is obtained by steam distillation after grinding the bulbs of Allium cepa, a Liliaceae herb. The yield is about 0.01% ~ 0.015% (fresh raw materials) or 0.05% (dry materials). It is produced everywhere in the world. Due to the low quantity and high price, it is often dissolved with solvent, emulsifiers such as gum arabic are added to emulsify, and then spray dried into powder before being used.

ONION CONCENTRATE - Introduction
FEMA 2817 is a commonly used edible condiment with special flavor and medicinal value. The following is a description of the nature, use, preparation and safety information of FEMA 2817:
Nature:
FEMA 2817 is obtained by soaking fresh onions in vegetable oil. It is pale yellow or light green in color, with a rich onion flavor and spicy taste. FEMA 2817 has antioxidant and antibacterial properties and also contains nutrients such as vitamin C and minerals.
Use:
FEMA 2817 is often used in cooking to add flavor and taste to food. It can be used in various cooking methods such as stir-frying, stewing, grilled fish, etc., and can be used to make soups, sauces and condiments. In addition, FEMA 2817 can also be used as condiments for cold dishes, such as mixing cold noodles and cucumbers.
Preparation Method:
The method of making FEMA 2817 is relatively simple. First, cut fresh onions into thin slices or small pieces, and then soak them in vegetable oil, such as cooking oil or olive oil, for a period of several hours to several days. Finally, the onion is filtered out to obtain the FEMA 2817.
