How long is the shelf life of donkey-hide gelatin?

Not only is donkey-hide gelatin edible, it also has good medicinal effects. Although it has a shelf life, the older the donkey-hide gelatin is, the better. Strictly speaking, donkey-hide gelatin has no shelf life. As long as there is no mold or odor on the surface, it can be eaten. Experiments have shown that if genuine donkey-hide gelatin is properly preserved, its efficacy will remain unchanged for hundreds of years.

The reason why a shelf life is added is because the country later stipulated that all medicines must have a shelf life limit, so the shelf life is 5 years. Store in a cool and dry place. As long as it is not weathered, the longer the donkey-hide gelatin is stored, the better. The dryness in it will also be eliminated, and you will not get a sore throat after eating it.

The shelf life of donkey-hide gelatin is generally 5 years, but if it is stored properly in a cool and dry place, it can generally be stored for a longer time. As long as it does not appear deformed, has a slightly fishy smell, and has a smooth and translucent surface, there is generally no problem.

How to preserve donkey-hide gelatin

Experts suggest that donkey-hide gelatin can be stored in a wooden box or a sealed box, with a little ash or other desiccant at the bottom. This can prevent the donkey-hide gelatin from becoming swollen and forming urine due to moisture. The container for storing donkey-hide gelatin also needs to be placed in a cool and dry place.

In addition, donkey-hide gelatin softens easily when exposed to heat and moisture, and easily breaks in dry and cold places, so it should be wrapped in oil paper and stored in a sealed manner to isolate it from external moisture and thus play a protective role. In summer, it can also be stored in sealed quicklime jars. Only by storing it in the correct way can its efficacy be guaranteed.

How to choose pure donkey-hide gelatin

1. Observe its color.

The genuine donkey-hide gelatin blocks are flat, with neat edges and corners, a shiny brown or black surface, and translucent edges. Fake products often have films of different sizes and thicknesses, pores of uneven sizes, a darker color, and a rough and dull surface.

2. Smell it.

Authentic donkey-hide gelatin has no skin odor and does not become soggy even in summer. After crushing it, put it in a cup, add appropriate amount of boiling water, cover the cup and let it sit for 1-2 minutes. When you open it again, the glue aroma will be strong. Or remove the outer packaging of the film, wrap it with a hot and damp towel for 1-2 minutes, and there will be a glue fragrance after opening it. The fake product has no glue fragrance, but has a fishy smell. When heated in water, there will be a layer of "oil" on the surface of the liquid and it will have the smell of pork skin soup.

3. Break it with your hands.

The genuine product is brittle and hard in texture. It will not bend when bent and is easy to break. There are no pores on the cross section. If you hit it hard, it will break into several pieces, that is, it is "hard and brittle". The fake ones are tough, not easy to break, and may even bend.
