2. Judging from the taste: the good quality green papaya powder has only the faint scent of green papaya, and it has a little bitter taste after washing with water, just like eating fresh papaya; If it has an off-flavor, unpleasant smell, especially the stale smell of prickly nose, it may be that the quality has deteriorated during production and storage, so the effect of this green papaya powder is much worse and it is quite painful to eat.
3. judging from the fineness, the finer the powder is, the more difficult it is to process, but the better it is to absorb, and the smaller the dosage, the faster it will take effect. The fineness of ordinary papaya powder is between 60-80 meshes, that is, 0.2-0.8mm, and that of good papaya powder is between 120-200 meshes, that is, 0.08-0.1mm.
4. Content of papain: The content of papain green papaya powder is the most important indicator of quality. The content of papain depends on the processing method of the product. The content in sun drying is the lowest, the content in low temperature drying is several times more, and the content in freeze drying is dozens of times that in sun drying. The quality of freeze drying is the best, but the cost is also the highest. Papain is very sensitive to temperature, and it will all fail when it exceeds 75 degrees, which is why papaya powder can't be washed with boiling water. People who don't know this don't know the quality of papaya powder at all. A simple way to judge the papain content of green papaya powder is to make it into paste with a small amount of warm water and apply it on the face or hands. The higher the content of tingling or fever, the higher the content of satiny after cleaning. The early breast dredging stage of papaya powder with low papain content will have a certain effect due to the efficacy of papaya, but it will have no effect in the next fat storage stage, and this breast enhancement effect is not good; Because of the low papain content, the effect of losing weight and whitening and rejuvenating skin is even worse.
5. When buying papaya powder, don't think that the quality of all papaya powder is similar. There are many processes from picking papaya to selling products, and the quality of products obtained by different processing methods, production equipment and quality management is very different. Pay attention to discrimination. Efficacy-oriented products mainly look at quality, not quantity. Eating a lot of poor quality things into your stomach doesn't have much effect.
