If the shelf life is not over, it will not affect the normal use. The capsule part of the soft capsule is composed of gelatin and edible additives. More than 80% of the gelatin is protein and contains less than 15% of water. Due to its physical properties, it is heated and dissolved into a liquid, and then cooled to become jelly. It is widely used in the pharmaceutical and health care industry as a capsule material for soft capsules. Because gelatin has the above characteristics, soft capsules will appear softer in the summer as the temperature rises (easy to stick), and winter will harden as the temperature drops. In addition to the influence of temperature, the soft and hard of gelatin also has a positive correlation. When the water content is high, it is soft. When the water content is low, it becomes hard. After the soft capsule is made, the moisture content in the soft capsule shell is contained in the air. The effect of water quantity, the result of its competition will affect its hardness. Because the water content in the winter air is generally low, the moisture in the soft capsule shell is hardened by the air, and on the contrary it becomes soft.
