First, the visual resolution.
1, we should look with our eyes, mainly at the color of pine pollen. Normal pine pollen is light yellow or beige. If the color is khaki or other dark colors, it is an abnormal color. There are two reasons for this phenomenon, one is deteriorated pine pollen, and the other is tabletting technology.
2. At present, the common tabletting process is mixing-drying-granulating-tabletting-coating. Wherein the drying, granulating and coating processes are at least above 80 DEG C.. In this process, the color of pine pollen will become khaki or dark yellow, and a lot of nutrients will be lost.
3. The simplest experimental method is: use one or two spoonfuls of pine pollen and slowly heat it to 60-80 degrees in a pot for about 5 minutes. After taking it out, it was compared with unheated pine pollen, and the truth was immediately revealed. Remember, the surface color of coated pine pollen tablets is not the color of pine pollen, and you must break it to see the true face of Lushan Mountain.
Second, check the tip of the nose.
Smell it with your nose, mainly the smell of pine pollen. Normal pine pollen has the fragrance of pine trees. If there is a musty smell, or there is no fragrance at all, or the taste is weak, it is not normal. The best way is to smell the original powder of pine pollen first, or pick some powder from pine trees and smell it yourself, and then compare it with the products you bought, so that you can distinguish the true and false Li Kui jy.
Third, the test on the tip of the tongue
1, taste it with your tongue, that is, taste the pine pollen, and see if there are any impurities. Take a pine pollen and chew it slowly in your mouth. Normal pine pollen has bitter taste, and the bitter taste of broken pollen is aggravated. If there is no bitterness at all, it must be fake. If you feel impurities such as sand and dust, it means that the pollen is not dusty and unclean.
2. In addition, because it is difficult to tablet pine pollen, many enterprises use sugar to increase adhesion, so it is difficult to distinguish bitterness. Generally speaking, sugar-free pine pollen not only has advanced tabletting technology, but also avoids the taboo that many elderly friends cannot eat sugar. At present, few enterprises in China can do this.
Extended data:
Pay attention to four aspects when buying pine pollen:
1. Not all pine pollen can be eaten casually, and it must undergo a complete safety toxicology test. For example, the pollen of Pinus massoniana, a Pinaceae plant endemic to China, has passed the toxicological safety test in the third stage, and has been scientifically proved to be a product with homology of medicine and food.
2. The origin of raw materials has a great influence on the quality. At present, the better pine pollen producing areas in China are: Pinus massoniana forest area in Qiandao Lake, Zhejiang Province, and Pinus massoniana forest area in Yunnan Province.
3. It is best for the production enterprise to pass the certification of green food or organic food, and have the invention patent and GMP certification.
4. There is the approval number of the word "food" and the "little blue hat" sign recognized by the US Food and Drug Administration, and it is marked as suitable for people. The best pine pollen to buy is broken pine pollen, which is more conducive to human absorption.
