What's the main roles and applications of Vanillin ?
The chemical name of vanillin is 4-hydroxy-3-methoxybenzaldehyde, also known as methyl protocatechualdehyde and vanillin. One of them, with sweet bean and powder aroma, can be used as fixative, coordinating agent and flavoring agent, widely used in food, beverage, cosmetics, daily chemicals and medicine and other industries. The proportions used in downstream industries are about 50% for food additives, 20% for pharmaceutical intermediates, 20% for feed additives, and about 10% for other uses.
Vanillin is currently one of the most used food flavoring agents in the world, and has the reputation of "the king of food flavors". It is mainly used as a flavor enhancer in the food industry and is used in cakes, ice cream, soft drinks, chocolate, baked candy And alcohol, the added amount is 0.01%-0.04% in cakes and biscuits, 0.02%-0.08% in candy, the maximum amount of baked goods is 220mg·kg-1, and the maximum amount of chocolate is 970mg·kg- 1. It can also be used as a food preservative additive in various foods and seasonings.
In the cosmetics industry, it can be used as a flavoring agent in perfumes and face creams; in the daily chemical industry, it can be used to modify the aroma in daily chemical products; in the chemical industry, it can be used as a defoaming agent, vulcanizing agent and chemical precursor; It can also be used in analytical testing, such as testing amino compounds and certain acids; in the pharmaceutical industry, as a medicament to shield odors.
Because vanillin itself has a bacteriostatic effect, it can be used as a pharmaceutical intermediate in the pharmaceutical industry, including in the treatment of skin diseases. Vanillin has certain antioxidant and cancer prevention effects, and can participate in the signal transmission between bacterial cells. In the future, these potential application fields will promote the rapid growth of the market demand for vanillin. By 2019, the global market for vanillin will be The annual consumption is about 20,000 tons.
Food preservatives are divided into two categories: natural preservatives and chemical preservatives, which are used in food production, circulation, storage and other processes to maintain food sensory properties, improve edible value, and prolong storage time. Compared with chemical preservatives, natural preservatives have the advantages of being harmless to the environment, low production cost, good biocompatibility, and good preservation effect.
Vanillin in food can be accurately detected by conventional methods such as UV-Vis spectrophotometry, chromatography, electrophoresis, etc. It is a kind of food preservative with high safety. The application of vanillin in food storage and preservation can be divided into bacteriostasis, anti-oxidation, stabilization of other components in food and inhibition of respiration rate.
The main roles of vanillin:
Vanillin is a natural bacteriostatic agent, which is often combined with other antibacterial methods in the food field, and the antibacterial effect of vanillin on different bacterial species is different. The bacteriostatic effect of vanillin is related to its concentration and pH value. Higher vanillin concentration and lower pH value are both beneficial to improve the bacteriostatic effect of vanillin. The bacteriostatic effect of vanillin on different bacterial species Different, compared with other strains, vanillin has better bacteriostatic effect on Escherichia coli.
Vanillin has an inhibitory effect on a variety of yeasts, and a high concentration of vanillin is beneficial to improve its bacteriostatic effect, but a high concentration of vanillin cannot kill yeast instantly. Compound fresh-keeping realizes the synergistic effect between fresh-keeping agents (or fresh-keeping methods), and is a generally accepted method for fresh-keeping of fruits and vegetables.
For example, for the prevention of Aspergillus niger contamination, the effective bactericidal dose of vanillin alone is 0.5% (mass fraction, the same below), and the mixture of 0.05% vanillin and 0.0025% cinnamaldehyde can play a bactericidal effect.
Vanillin also plays an important role in assisting bacteriostasis and bactericidal. In the current production process, heat sterilization is still the most common sterilization method in fruit juice processing, and its treatment methods are generally pasteurization and high temperature instantaneous sterilization. Traditional sterilization methods often lead to the destruction of nutrients in juice and browning of products.
The mechanism of action of antioxidants with similar structures is different. Vanillin mainly accelerates the scavenging of free radicals by oxidizing the product vanillic acid. The antioxidant effect of vanillin can significantly prolong the shelf life of oily food and has a negative effect on its rancidity. cover up. The isomer of vanillin, o-vanillin (2-hydroxy-3-methoxybenzaldehyde), has been shown to scavenge peroxynitrite anions, but is not a good free radical scavenger agent.
Other ingredients in stabilized food
Studies have shown that the reaction product of vanillin helps to stabilize other ingredients in food: Resveratrol is a natural functional ingredient. In order to improve its stability and give full play to its functional role, the reaction between vanillin and chitosan The resulting reticulated chitosan microspheres are coated with resveratrol, which helps to control the release of resveratrol; the condensation product of vanillin and amino group has a good ability to complex with metal ions, which can effectively improve the release of resveratrol. Stability of Included Substances.
