Identification of ginger oleoresin

Because of its remarkable effect, ginger oil has made rapid progress in the beverage industry, massage industry and seasoning industry in recent years However, there are all kinds of ginger oil on the market, which makes many consumers confused about what kind of ginger oil is suitable for them Xi'an Lvtian Biotechnology Co., Ltd summarizes the following three points based on its long-term production and sales experience, and invites friends in and out of the industry to learn from them and put forward valuable suggestions 1 The sensory evaluation method of ginger oleoresin the most simple and direct method is to determine the quality of ginger oleoresin by sensory evaluation Now I will share the specific identification methods for your reference 1 Look at the color 2 Look at the hanging wall 3 Take 1-3 drops of ginger oleoresin from the smell and apply it on the back of the hand evenly After 3-7 minutes, smell the smell You can smell the smell with ginger characteristics without any other strange smell 4 Taste 5 According to the feeling 2 The experimental judgment method of the quality of raw ginger oil resin We take ginger oleoresin of our company as the reference material, and make a detailed comparison of ginger oleoresin of other companies provided by our customers through the experimental method I will share the comparison results here This method is also applicable to other oil products I hope that friends who see this article can identify oil products through some simple methods 1 Oil solubility test 2 Water solubility test the above pictures are from please indicate the copyright for forwarding, thank you 3、 The scientific detection method is essential in the identification of ginger oleoresin It can directly reflect the quality of ginger oleoresin However, due to the high cost of testing, most customers do not test it, which is a reflection of their own irresponsibility to consumers So which aspects of the test can be used to distinguish the advantages and disadvantages of ginger oleoresin? In my opinion, it mainly includes the following four kinds of routine data detection: 1 The content of gingerols in ginger oleoresins is detected by HPLC (liquid chromatography), and the content of gingerols in ginger oleoresins should be between 20% and 30 There are two possibilities when the content of gingerols is less than 20%: 1 The content of gingerols is decreased due to improper storage for a long time; 2 The agricultural residues of gingerols are scanned by the method of combination of liquid and gas Ginger, as a kind of agricultural products, its pesticide residues can not be completely avoided, so it is necessary for manufacturers to select strict requirements in raw materials to ensure that ginger oleoresin extracted by ginger meets national standards, or even EU standards 3 The ginger oleoresin extracted by supercritical carbon dioxide is easy to control in the aspect of heavy metals, but as a routine test standard, it still needs to be tested 4 The microbial ginger oleoresin itself has a strong bactericidal effect We have tested the data for many times and all of them meet the national standards But for a long time, the index of mould and yeast will increase slightly As a routine detection index, it is very necessary to detect it The above three judgment methods (sensory judgment, experimental judgment and detection judgment) can effectively determine the quality of ginger oleoresin, and it also has certain reference significance for the judgment of other oil products If you have a better way to judge the quality of this product, please do not hesitate to give advice.
