There are several ways to identify good ass hide glue

The identification methods of good ass hide glue mainly include observing the appearance, smelling the smell, tasting the taste, testing the solubility and checking the packaging logo.

I. Appearance

High quality ass hide glue usually presents uniform brown black or black, with smooth and flat surface and neat edges without defects. Under light, it appears semi transparent, with a hard but moderately brittle texture, and produces a crisp sound when struck. Poor ass hide glue may have uneven color, rough surface or obvious bubbles and impurities.

II. Smell the smell

Authentic ass hide glue has a unique flavor, which is pure and not pungent. ass hide glue processed with yellow rice wine will have a light wine flavor. If you smell a fishy, rancid, or other unpleasant odor, it may be due to impure raw materials or improper storage leading to spoilage. Some low-quality products will add essence to cover up the odor, which is too strong and unnatural.

3. Taste

Put a small amount of ass hide glue in your mouth. High quality ass hide glue tastes slightly sweet at the first taste, then bitter. After melting, it tastes fine without sand. Fake and inferior products may have obvious sweetness, astringency, or saltiness, and there may be residual impurities after melting. The traditional ass hide glue has a slight sense of colloid, but it should not stick to the teeth.

IV. Test the solubility

Take a small piece of ass hide glue and put it into hot water. The authentic product will gradually dissolve into a clear solution, which can be re coagulated into a frozen state after cooling. Poor quality products may experience incomplete dissolution, cloudy solution, or inability to re solidify. The dissolution rate is too fast, and auxiliary materials such as gelatin may have been added.

V. Check the package identification

The package of regular ass hide glue products should include the drug approval number, manufacturer, production date and other information. High quality ass hide glue mostly uses donkey hide as raw material, and the source of raw material will be clearly marked. Pay attention to checking whether the anti-counterfeiting label is complete and avoid purchasing products with three no labels. Some time-honored brands may have traditional craftsmanship certification marks.

When purchasing ass hide glue, it is recommended to choose a regular drugstore or brand store. After purchase, it should be sealed and stored away from light. Before taking it, you can consult a traditional Chinese medicine practitioner for diagnosis and treatment. For those with a hot constitution, the dosage should be controlled. Ass hide glue can be used with black sesame, walnut and other ingredients to make Tonic Diet, but it should be stopped during cold and fever. The surface of ass hide glue preserved for a long time may appear slight hoarfrost, which is normal and does not affect the quality.
