Rosin is also a common industrial raw material, but many people have noticed it is probably news of "rosy hair removal." The first is to say that "rosettes are very harmful to plucking" and are therefore banned. Then said that with a safe "edible rosin" can be used for plucking. Chickens, ducks, pig's heads, pig's feet and other foods have a lot of fluff, which is very troublesome to remove. If there is a kind of thing that is applied to the top and then torn off, the villi can be removed, which will undoubtedly greatly reduce the labor intensity. This kind of thing can be called "plucking agent." Asphalt can achieve this function. Put the feet of chickens and ducks or pigs' pigs into the molten bitumen and take out the bitumen to cool down to a solid. Because the binding force between asphalt and wool is much greater than the binding force between wool and skin, when the asphalt is torn off, the fluff on the meat is also removed. However, bitumen is an industrial waste with complex composition and no shortage of harmful substances. When attached to the skin, the pores of the skin expand, and harmful substances may be absorbed into the meat. No matter how good the function is, if there are doubts about security, it can only endure the pain. Therefore, bitumen picking has long been banned. Rosin, which can play a similar role, also enters people's field of vision. There are two types of commonly used rosin. One is the collection of pine oleoresin secreted from pine bark, followed by some refining and processing. "Gum Rosin". In China, gum rosin accounts for the majority of rosin. Another way is to cut the stumps of old pine trees into pieces, extract pine resin with a solvent, separate and refine them, and finally obtain “wood rosinâ€. In the United States, wood rosin accounts for a larger proportion. Rosin is a “natural product†from pine trees, which is mainly composed of various organic acids, which can account for 90% of the refined rosin. The remaining 10% is a neutral component that includes many organic acids that have been esterified. In Chinese traditional medicine, rosin is also used as a medicinal material. In this way, "natural products" plus "traditional Chinese medicine" are enough to convince many people that rosin picking is not a problem. However, rosin is also a complex mixture, which also contains harmful ingredients such as lead and other heavy metals. In addition, its composition is complex and uncontrollable, and it is also known to repeatedly heat and reuse the hair during plucking. Compared with asphalt, "Rosin Plucking" is only fifty steps and laughing hundred steps. Therefore, "Rosin Plucking" was also banned. In fact, what harm it has in the end is not "well known" as the media said. The real situation is "not clear." In the food field, "unclear" and "no safety data" are enough to prohibit its use. The purified rosin reacts with edible glycerin to obtain "rosin glyceride." Normal oil is lighter than water and cannot be miscible with water, so it will delaminate when dispersed in water. The rosin ester is heavier than water and can be mixed with oil. The density of the mixture is closer to that of water, so it is not easy to separate. In addition, rosin glycerides can also act as emulsifiers. In this way, in the beverage, it has a place of use, such as helping the citrus oil to stably exist in the beverage. With its use, it also has the motivation to study its safety. Doing a lot of research abroad, mainly for wood rosin glycerides. First, its chemical composition was determined and it contained no known toxic or harmful components. Secondly, toxicity tests were conducted on animals and it was found that they did not accumulate in animals and did not decompose, and animals did not show adverse reactions at a considerable dose. After using the safety factor to cover the differences between humans and mice, the International Food Additives Commission (JECFA), the U.S., and the European Union have all approved its use as a food additive. The safe intake limit is 25 mg per kilogram of body weight per day. In addition to the previously mentioned methods for helping citrus oils to be dispersed in beverages, they are also used in chewing gums as plasticizers, in food processing processes as auxiliaries and containers. The acquisition of gum rosin does not damage pine trees, and wood rosin is extracted from dead pine trees. Relatively speaking, gum rosin must be more "sustainable". In the U.S., there are beverage manufacturers who believe that the chemical composition of gum rosin and wood rosin esters is equivalent and that gum rosin esters are used instead of wood rosin esters. In 2002, they filed an application. However, the FDA's response at the end of the year did not consider that the evidence they submitted was insufficient to prove that this “composition is equivalent†and therefore did not approve it. The company was not discouraged and added evidence to apply again. The FDA published this application in 2003 and was questioned. It is questioned that the ester rosin ester and wood rosin ester have a big difference in the source of raw materials and the production process, and there are certain differences in the composition analysis of the product. Moreover, the analysis shows that "similar" does not necessarily mean that they are similar, but it may also be "cannot tell the difference." In 2005, the FDA issued a final ruling that the challenge was not established. For example, the composition of the two rosin glycerides is similar, and the difference is not enough to bring about safety concerns. The composition of rosin is related to the place of production and the growth condition of pine trees, and it also has an indicator range; the allegation of analytical methods There is no scientific literature support and so on. Finally, the FDA approved the manufacturer's application to allow the use of gum rosin esters instead of wood rosin esters. Later, JECFA also endorsed this conclusion. Similar applications have been made in Europe, but the European Food Safety Authority (EFSA) believes that the current data is not sufficient to confirm that the two are equivalent and therefore there is no approval. In China, both rosin glycerides have been approved. In addition to being used as a food additive, it has also been approved for plucking animal products. In general, such rosin glycerides are called "edible rosin." They are not only different from the "food grade" and "industrial grade" but also the chemical composition. The “rosin†used for plucking must be the rosin glyceride that is commonly known as “rosinâ€.
In terms of market, China's export market of plant extract
products is relatively stable, the United States, Japan, France, has been the
main market of plant extract products. In recent years, Mexico and India have
also imported a large number of Chinese herbal products, mainly pigment
products. Plant extracts export market in 2011, except Latin America slightly
tightened, other continents showed significant growth in exports and volume.
Asia, Europe and North America are still the main export regions of China's
plant extracts, and the export to these three regions accounted for 82.6% of
China's total export of plant extracts in 2011.
Asian market: China's export of plant extracts to Asia is $440
million, accounting for 39.4%, Japan, Southeast Asia and Western Europe are the
main export markets of Chinese plant extracts. The United States accounted for
13.91% of the total, mainly because dietary supplement use has become a habit
for most Americans, which has led to an increase in demand for plant extracts
in the world's largest dietary supplement market. In Japan and South Korea,
mulberry leaf extract and other cosmetic products are mainly used; As the
world's largest herbal medicine market in Europe, products with plant extracts
as raw materials are favored by local consumers
Southeast Asia, Middle East, Africa and other emerging markets of plant extracts. Shaanxi Kepler Biotech Co.,Ltd , https://www.keplerherb.com
