Pharmaceutical Health Industry
In the pharmaceutical health industry, gelatin is used to make the shells of hard and soft capsules, tablets, granulation, suppositories, plasma substitute for medicines, dietary/health supplements, syrups, etc. It is highly digestible and serves as a natural protective coating for medicines.

Photography
The first account of its use in photography is in the British Journal of Photography for September 1871, when Dr. Richard Leach Maddox suggested that the sensitizing chemicals could be coated on a glass plate in a gelatin rather than a collodion emulsion (usage silver chloride which only valid for 10 minutes before the plate dry).

Nutraceuticals
The use of gelatin in the nutraceutical industry is widespread. Gelatin not only serves as a excipient (drug transport; important to keep other drugs from being released too early in the assimilation process), but also is an excellent and economical source of multiple amino acids. Gelatin is the foundation of many nutritional and arthritis/joint care formulas. It is also widely used for nutritional bars and protein drinks.

Cosmeceuticals
Gelatin has been used for many years in the cosmetics industry as “hydrolyzed animal protein” in shampoos, conditioners, lipsticks, and fingernail formulas. Recently additional uses for gelatin are being found as a collagen source in topical creams and other value added cosmetic products. (other examples: bath oils, moisturizing lotion, skin creams)

-silk fibroin fibers with exceptionally lustrous/fine appearance, soft-to-touch texture, ease of dyeing, superior mechanical properties, good biocompatibility and impressive moisture-absorption abilities. 

-fashion apparel, luxury clothing and furnishings. 

MEDICAL APPLICATIONS
1. Surgical Suture (a stitch that is used to sew a wound together)

-Silk fibroin has high strength, low bacterial adherence and good handling/tying characteristics.
-Silk is typically braided when used as suture, rendering it susceptible to inducing inflammatory reactions.

2. Tissue Engineering

The construction of fibroin into different matrices/morphologies for tissue regeneration including ligament, tendon, cartilage, bone, skin, liver, trachea, nerve, cornea, eardrum, bladder, etc.

3. Non-woven and woven silk scaffolds

-Silk fibroin fibers can be fabricated into non-woven or woven matrices for use as tissue engineering scaffolds. 

1. Silk sericin membranes are good bandage materials and the film has adequate flexibility and tensile strength. Due to its good biocompatibility and infection resistant nature, it is a novel wound coagulant material. Its flexibility and water absorption properties promote smooth cure for defects in the skin and do not cause any peeling of the skin under regeneration when detached from the skin.

2. Intake of sericin containing food relieves constipation, suppresses development of bowel cancer and accelerates the absorption of minerals. 

Silk sericin or in combination with silk fibroin has bee used in skin, hair and nail cosmestics. It is used in the form of lotion, cream and ointment which increase skin elasticity, antiwrinkle and antiaging. 

- As the skin ages, it loses some of its elasticity, resulting in wrinkles. Therefore, collagen is an important component for cosmetic formulation, where it is an effective natural humectant with high substantivity.  It is the most abundant protein in mammals, making up about 25% to 35% of the whole-body protein content. Collagen products are used in medicine and dentistry for many purposes, including wound dressings and as matrices for tissue growth. It has been used as implantable carriers for bone inducing proteins and is used as a bone void filler and substiture due to its ability to encourage bone growth. Collagen sponges are used for bone-related protein carriers.As the chief structural protein of the body, the properties of collagen that make it suitable for use in dentistry are dependent upon characteristics of amino acid composition and sequence.
