How to extract essence

Introduction: in order to make the fragrance of the product more durable, many manufacturers add flavor to the products Then how do you extract the essence? Is it harmful to the food? About these two questions, you can listen to the introduction of Xiaobian Xiaobai safety net Food flavor is a kind of food additive which can emit aromatic flavor at room temperature and make special taste and taste It is a kind of food additive, which is made up of various flavors and artificial chemical additives Food flavors are based on natural food flavors, natural and natural equivalent spices, synthetic flavors carefully prepared into a variety of flavor flavor with natural flavor The dosage forms of food flavors include liquid, powder, microcapsule, slurry and so on How to extract essence? Xiaobian, Bai Bai, summarizes several methods of extracting essence by reading the data 1, distillation: when the plant material is placed in boiling water, the essential oil containing fragrance will escape with the steam, and when the steam condenses into water, the grease will float on the water surface, and then we can collect them This process may need to be repeated several times to obtain the highest possible purity of essential oil 2 Extract with volatile solvent: the perfume is put in a porous metal plate, then put into the extractor, let the volatile solvent (such as ether) pass through the extractor, then enter the distillation pot, where it becomes a semi solidified substance, called "freezing" "Freezing" includes essential oils and a waxy substance called Rose wax Using another technique that uses alcohol can separate the two The essence of this pure and high concentration essential oil is called essence 3 Oil absorption method: put flower heads in oil or fat to absorb their fragrance Spread flowers with special fat coated glass and extract essential oil with alcohol This method requires a lot of labor, and it is no longer used 4 Squeezing: this method is usually used to extract the essential oil from the peel of citrus fruits The peel is placed in the middle of the roller, and the sesame oil is separated under the centrifugal force In other words, it's the power of rotation that throws the oil out 5 "Vacuum refining technology" or "living flower technology": put a kind of fragrant substance, such as a flower, in a special container, and the container is vacuumized After a while, the fragrance of the flower will escape in the container About an hour and a half later, the released flavor channel will be pumped into a gas differentiator, which will accurately analyze the basic components of the escaping substance And measurement The above methods are the methods of extracting essence You can learn from them Is it harmful to food? Natural flavors are not mentioned Now we mainly talk about synthetic flavors It is harmless to use artificial flavors in the prescribed dosage standard As long as the chemical ingredients in synthetic flavors are permitted by the state However, if the synthetic flavors are used excessively or there are illegal chemical substances in the essence, it will have a great influence on the human body Therefore, when adding flavors in food, we should not only pay attention to the dosage, but also pay attention to the ingredients of synthetic flavors About the extraction method of essence, Xiaobian simply introduces several kinds, and there are many questions about essence You can pay more attention to food safety knowledge and learn more information For food safety, we can use food safety detector to detect whether there are harmful substances in food Editor in charge: he xianrob
