What Are Gelatin Capsules Made Of

Some medicines (powders or granules) are irritating to the esophagus and gastric mucosa, and some are medicines that have a bad taste, are easy to volatilize, are easily broken down by saliva in the mouth, and are easily inhaled into the trachea. These medicines are packed in capsules, which not only protects the properties of the medicines from being destroyed, but also protects the digestive organs and respiratory tract. The most common one is gelatin capsules, which are edible. So, what are gelatin capsules made of? 　　 Gelatin capsules are made of gelatin. Gelatin is partially degraded from the collagen in the connective tissues of animal skin, bone, muscle membrane, muscle charm, etc. into white or light yellow, translucent, slightly shiny flakes or powder. 　　The water and inorganic salts in gelatin account for about 16%, and the protein content accounts for more than 82%. Similar to maternal collagen, gelatin is also composed of 18 kinds of amino acids, of which the content of imino acids Pro and Hyp is higher. The triple helix-like structure in gelatin gel is mainly maintained by intramolecular hydrogen bonds and hydrogen bond hydration. Pro's -NH and Hyp's -OH can form hydrogen bonds with other amino acid side chain groups and water molecules, which is beneficial to the triple helix-like structure. Structural stability. 　　 Gelatin solution can form a gel with a certain hardness and not flowing. When the gelatin gel is stimulated by the environment, it will respond accordingly, that is, when the composition of the solution, pH value, ionic strength and temperature, light intensity, electric field and other stimulation signals change, or when it is stimulated by specific chemical substances, it will gel. The glue will mutate and show phase transition behavior. 　　Gelatin is divided into edible gelatin, medicinal gelatin, industrial gelatin, photographic gelatin, skin glue, and bone glue according to different production materials, production methods, product quality, and product usage. Among the industrial glues, people are used to call the protein gelatin used to extract hydrolyzed animal protein protein gelatin, the feed glue dedicated to feed additives is called feed gelatin, and the match glue used in the match industry is called match gelatin. The hot-melt gelatin used for packaging and other products is called hot sol powder, and the gelatin that is dried by natural air is called soil gel.
