Teach you how to recognize collagen

Collagen is an essential substance for skin beauty. So how can we visually identify the quality of collagen without any high-precision instrument? Let's take a look.

Nose discrimination: (smell smell)

1. Put the collagen powder into a pre-prepared plastic ziplock bag, fill it in half the volume of the ziplock bag, seal the sealing strip, then shake the ziplock bag up and down about 10 times, then unpack the ziplock bag. Seal, immediately smell the self-sealing bag mouth, the smaller the odor, the better the quality of the collagen peptide. 2. Dissolve the collagen powder at a concentration of 10% (10 g of collagen dissolved in 90 ml of water), apply a little to the back of the hand, wait Immediately after drying (about 10 minutes or so), smell the back of the hand. Poor quality collagen can smell a pungent smell or astringency.

Tongue discrimination: (taste dissolve)

1. With your tongue, good collagen will make you feel like it is “hot”. This is a way to distinguish the purity of collagen. High-purity collagen will release heat when it is hydrolyzed.
2. Use the tongue to identify the rate of collagen melting. The faster the dissolution, the easier it is to absorb the collagen.

Eye discrimination: (see color)

1. Pour a small amount of collagen powder on a piece of white paper to compare the color of white paper and collagen. The closer the collagen color is to the white paper color, the better the quality of the collagen you buy. Good quality collagen powder should be white or nearly white. On the contrary, the low-quality collagen powder is yellow, gray, grayish yellow or slightly reddish-brown and has a dull color and no luster.

2. In a glass with good transparency, dissolve 5 grams of collagen peptide in 95 ml of water. Normal temperature is enough. When the collagen is completely dissolved, pour 100 ml of water into another cup to compare the liquid in the two cups. colour. The closer the solution is to the clear water, the purer the quality of the collagen peptide. The color of the low-quality collagen solution is much more pronounced, generally yellow, and the darker the color, the worse the quality. Everyone's eyes have to be brightened.
