Gelatin is a multifunctional ingredient that is used in foods, pharmaceuticals, cosmetics, and photographic films as a gelling agent, stabilizer, thickener, emulsifier, as well as film former.6

As a thermoreversible hydrocolloid with a small gap between its melting and gelling temperatures, gelatin provides unique advantages over carbohydrate-based gelling agents. Gelatin is mainly produced from porcine skin, and cattle hides and bones.6

Some alternative raw substances have recently garnered attention from both researchers and the industry not only because they overcome religious concerns shared by both Jews and Muslims but also because they may provide scientific advantages over gelatins from mammal origins.21

Fish skins from a number of fish species a type of substance that has been comprehensively studied as a source for gelatin production. Fish skins have a significant potential for the production of high-quality gelatin with different melting and gelling temperatures over a much larger range than mammalian gelatins but have a sufficiently high level of gel strength and viscosity.6

Interestingly, horse gelatin has been studied and it was found that in the horse, gelatin influences the homeostasis of the amino acids required for cartilage synthesis 8. An increasing number of novel applications have been found for collagen and gelatin.2

Gelatin is generally recognized as safe (GRAS) by the FDA to be a non-hazardous food or food ingredient.12 The FDA withdrew its approval for the use of all intravenous drug products containing gelatin. Gelatin continues to be approved for other routes of administration.24

Gelatin is used for weight loss and for treating osteoarthritis, rheumatoid arthritis, and brittle bones (osteoporosis). Some people also use it for strengthening bones, joints, and fingernails. Gelatin is also used for improving hair condition and to shorten the recovery after exercise and sports-related injury 15. Gelatin is used in preparations of foods, cosmetics, and medicine 15.

Plasma volume expander in hypovolaemic shock 16. Haemostatic 16.

Gelatin-based hydrogels are being used in drug delivery and tissue engineering because they are able to promote cell adhesion and proliferation. In addition, these hydrogels can be used as wound dressings because of their attractive fluid absorbance properties. Manufacturing technologies such as ultraviolet stereolithography and two-photon polymerization can be used to prepare structures containing photosensitive gelatin-based hydrogels 13.

Gelatin contains collagen, which is one of the materials that make up cartilage and bone 15.

In addition to their well-established value as a nutritional protein source, collagen and collagen-derived products may exhibit various potential biological activities on cells and the extracellular matrix through the corresponding food-derived peptides post-ingestion. This could justify their applications in dietary supplements and pharmaceutical agents 2.

Gelatin is a protein that is used as a hemostatic in surgical procedures. It is also used as a plasma volume expander in hypovolemic shock. Gelatin rods structures may also be used to temporarily block tear outflow in cases of dry eye 16.

Mechanism of action

It works as a hemostatic by providing a physical framework within which clotting may occur 16.

As a volume expander, gelatin remains in the vascular space. When used in the treatment of hypovolaemia gelatin can produce a significant increase in blood volume, cardiac output, stroke volume, blood pressure, urinary output and oxygen delivery, increasing volume and pressure 18.

For intravascular volume expansion, the majority or gelatins produce an effect which is almost equivalent to of which are mild, although severe reactions albumin, with a duration of action of 3 to 4 hours to have been reported 19.

Gelatin or collagen chains suspended in solution can be covalently cross-linked to form matrices that are able to swell in the presence of aqueous solutions, forming what are called gelatin hydrogels. Hydrogels, characterized by their hydrophilicity and insolubility in water, have the capability of swelling into an equilibrium volume while maintaining their shape. The chemical cross-linkers used may be either small bifunctional molecules or polyfunctional macromolecules, for example, glutaraldehyde 22.


The bioavailability of gelatin was indirectly studied by the determining the bioavailability of total hydroxyproline in gelatin using a pharmacokinetic method after oral ingestion in rats.

The relative and absolute bioavailability of gelatin were 74.12% and 85.97%, respectively. The amino acid profile of plasma showed that 41.91% of the digested gelatin was absorbed from the intestine in the peptide form, and there was a linear correlation between the absorbed amount of an amino acid and its content in gelatin (R(2) = 0.9566). Furthermore, 17 types of collagen peptide were purified by multi-step chromatography and identified with ultra-performance liquid chromatography-electrospray ionisation-mass spectrometry 9.

LD50 Rat >3750 mg/kg 23.

Gelatin solutions have shown to increase the risk of anaphylaxis and may be harmful by increasing mortality, renal failure, and bleeding likely due to extravascular uptake and impairment of coagulation. 4.

Gelatin can cause an unpleasant taste, a sensation of abdominal heaviness, bloating, heartburn, as well as belching 15.

Using gelatin as a plasma expander appears to have no significant advantages over crystalloids or isotonic albumin on mortality and may have a slightly higher risk of requiring allogeneic blood transfusion in perioperative and critically ill patients.

A meta-analysis found that using gelatin as a volume expander in vivo has no significant advantages over currently used volume expanders such as isotonic albumin or crystalloids and may slightly increase the risk of requiring a blood transfusion 20.
