Molecular Formula | C4H5NS |

Physical and Chemical Properties | The child is spherical and very small. The 1000-grain weight of white mustard is about 6.5g; The 1000-grain weight of black mustard is only 1.3g, and the volume is 1/2 of that of white mustard. Both have a strong spicy and stimulating taste. It contains fat 25% ~ 35% and can be removed by pressing. White mustard seeds do not contain volatile oil, and its main component is white mustard glucosinolate (sinalbin). After encountering water, due to the action of enzymes, it produces strong pungent and spicy white mustard disulfide glucosinolate oil and other substances. The volatile essential oil in black mustard is 0.25% ~ 1.25%, and the main component is black mustard glycoside or black mustard glucosinolate potassium. After encountering water, it produces acrylic isothiocyanate and potassium bisulfate and other pungent and spicy substances. |

brief introduction | fish make fire and produce phlegm, radish and cabbage keep safe, restless abdominal flatulence, asking immortals and asking gods for peace, panacea money is not expensive, and carefully found it around. Today, Xiao U will introduce a panacea for exhaust gas-mustard oil. Mustard oil is actually a general term for isothiocyanate compounds, which has anti-cancer effects. It can not only prevent cancer, but also solve flatulence. Mustard oil contains sulfide, which generally has a spicy smell, so when we eat radish raw, we will feel a spicy taste. |
main ingredient | mustard oil is a mixture of various glucosinolates. According to the different side chains in the glucosinolate molecule, glucosinolate is divided into aliphatic glucosinolate (such as allyl glucosinolate), indole glucosinolate (such as indole -3-methyl glucosinolate) And aromatic glucosinolate (phenyl glucosinolate or benzyl glucosinolate). |
Source | Green mustard comes from Wasabi, a beehens plant in the cruciferous family. The isothiocyanate degradation products of mustard oil in horseradish are the source of the spicy taste of mustard, and the spicy taste of propyl isothiocyanate is the strongest. The spicy ingredients in mustard oil can kill parasites, so the combination of thin sashimi and mustard not only creates a special taste conflict, but also makes sashimi safer to eat. Mustard oil is not the exclusive substance of horseradish, it also exists in other cruciferous plants, such as horseradish, brassica mustard, radish white radish, and maca, etc., also contain mustard oil. |
efficacy and function | glucosinolate is an important defense substance for plants themselves. when plants are damaged, glucosinolate can be produced to defend against pathogenic bacteria, insects eating and other attacks. For the human body, glucosinolates also have many beneficial effects, such as relieving cough and resolving phlegm, dredging orifices and promoting blood circulation, nourishing qi, and promoting intestinal peristalsis. The reason why radish has the title of "little ginseng" has a lot to do with the rich content of glucosinolates in its epidermis. Studies have shown that glucosinolate and its degradation products have a preventive effect on a variety of neurodegenerative diseases (such as Parkinson's syndrome, Alzheimer's disease, amyotrophic lateral sclerosis, multiple sclerosis, etc.); benzyl glucosinolate and its degradation product benzyl isothiocyanic acid can effectively reduce the incidence of tumors in chemical carcinogenic animal models; another metabolite of glucosinolate, sulforaphane, it has been proved in in vitro experiments to have an inhibitory effect on cancers such as lung cancer, gastric cancer, colon cancer, breast cancer, bladder cancer, and prostate cancer. Its precursor 4-methylsulfinyl butyl (4MS) glucosinolates has been used as drugs for the prevention and treatment of cancer. It is marketed in the United States; glucosinolates and their degradation products in food can also reduce the risk of cardiovascular disease by reducing the level of cholesterol in the blood, and glucosinolate and its degradation products also have a certain inhibitory effect on diabetes. |
application field | mustard oil is a natural plant essential oil extracted from mustard seeds. it has a strong pungent volatile and spicy taste. Mustard oil is very spicy, can stimulate the secretion of gastric juice and saliva, and has the effect of appetizing, can enhance people's appetite; mustard has a strong detoxification effect, can relieve fish and crab accumulation of toxic substances, therefore, when eating raw salmon and other fresh food, people often with mustard. |
extraction process | process flow: mustard seed → soaking → crushing → acid adjustment → hydrolysis → distillation → separation → mustard essential oil → blending → filling → labeling → finished product. The main points of operation are as follows: 1) Raw materials: Mustard seeds with full grains, large grains and dark yellow color are selected as raw materials. 2) Soaking: Weigh mustard seeds, add 6-8 times of warm water at 37 ℃, and soak for 25-35h. 3) Crushing: The soaked mustard seeds are put into a grinder to grind, and the finer the grind, the better, to obtain mustard paste. 4) acid adjustment: adjust the pH of mustard paste to about 6 with white vinegar. 5) hydrolysis: put the mustard paste with adjusted pH into a hydrolysis container, place it in a constant temperature water bath, and hydrolyze at about 80 ℃ for 2~2.5h. 6) Distillation: Put the hydrolyzed mustard paste into a distillation device, and use steam distillation to evaporate the spicy substances. 7) Separation: The distillate after distillation is an oil-water mixture, which is separated by an oil-water separator to obtain mustard essential oil. 8) Mix mustard essential oil and vegetable oil according to the formula ratio and stir evenly, which is mustard oil. 9) Filling: The mustard oil is filled in a glass bottle that has been cleaned, disinfected and dried in advance, labeled and sealed, which is the finished product. |

usage limit | FEMA(mg/kg): black mustard: seasoning 5200; Meat products 2300. White mustard: soft drink 350; Baked food 20; Seasoning 8200; 1400 of meat products; Pickled products 2500~3800. |
use | spices. Widely used in various flavoring agents, such as preparing mustard powder and mustard sauce. The whole grain can be used for pickling or cooking with vegetables. The amount used depends on the need. Spices. For kimchi, canned food, sauce, seasoning, etc. |
production method | the seeds of annual cruciferous herbs mustard (nigra Brassica black mustard or B.Alba white mustard) are crushed, added to warm water, stirred, left for one day and night, and distilled in water. The yield is about 0.9%. Such as squeezing seeds by cold pressing. The resulting cake is of better quality with water and steam distillation. The powdery product is formed by squeezing mature seeds to remove most of the fat and then drying and crushing. |
