1. What is vegetal chitosan?

Chitosan is a natural biopolymer that is primarily derived from chitin, which is the second most abundant natural polysaccharide after cellulose. Chitin is commonly found in the exoskeletons of crustaceans like crabs, shrimps, and lobsters, as well as in the cell walls of certain fungi like mushroom, aspergillus niger.

Structure and Properties:

• Chemical Structure: Chitosan is obtained by deacetylating chitin. This process involves removing acetyl groups from chitin, resulting in a polymer that has free amine groups.
• Solubility: Unlike chitin, chitosan is soluble in acidic to neutral solutions, making it more versatile for various applications.
• Biocompatibility and Biodegradability: Chitosan is known for its excellent biocompatibility and biodegradability. It’s non-toxic and can be broken down by natural biological processes.

Chitosan, sometimes known as deacetylated chitin, is a natural polycationic linear polysaccharide derived from partial deacetylation of chitin. Chitin is the structural element in the exoskeleton of insects, crustaceans (mainly shrimps and crabs shell), and cell walls of fungi (oyster mushroom, agaricus bisprous and aspergillus niger), and also is the second most abundant natural polysaccharide after cellulose.

Chitosan, a natural polysaccharide prepared of fungal origin, is initially extracted and purified from reliable and abundant food or biotechnological fungal sources such as Agaricus bisporus or Aspergillus niger.

Chitosan is composed of glucosamine sugar units (deacetylated units) and N-acetyl-D-glucosamine units (acetylated units) interconnected by ß→(1.4) type linkages.

Uses and Applications:

1. Medical and Pharmaceutical Fields: Due to its biocompatibility and non-toxic nature, chitosan is used in wound healing, drug delivery systems, and as a biomaterial in tissue engineering.
2. Water Treatment: Its ability to bind with heavy metals and other contaminants makes it useful in water purification and treatment processes.
3. Agriculture: As a natural biostimulant and elicitor, chitosan is used to enhance plant growth and provide resistance against pathogens.
4. Food Industry: It’s used as a food additive for its antimicrobial properties, and as an edible film or coating to enhance the shelf life of perishable food products.
5. Cosmetics and Personal Care: In this realm, it finds use as a thickener, moisturizer, and film-forming agent, particularly in hair and skin care products.

Chitosan has been widely used in various fields, including wine, pharmaceuticals, dietary supplement, medicine, agriculture, and food industries, due to its biocompatibility, biodegradability, and non-toxicity. In recent years, researchers have investigated the use of vegetal chitosan, which is derived from fungal or plant sources, as a sustainable alternative for use in wine applications.

Variants:

• Traditional Chitosan: Traditionally sourced from marine crustaceans.
• Vegetal Chitosan: Derived from fungal sources, offering an alternative for those seeking non-animal derived products.

In summary, chitosan’s versatility, biodegradability, and non-toxic nature make it a valuable material across various industries, from healthcare to cosmetics. Its ability to be derived from non-animal sources also makes it an appealing option for vegetarian and vegan-friendly products.

2. What are the advantages of vegetal chitosan?

Vegetal chitosan, also known as fungal chitosan or mycelium chitosan, is a type of chitosan derived from the cell walls of fungi (mushroom and aspergillu niger). It has several advantages over traditional chitosan derived from shellfish, including:

• 1. Vegan and vegetarian-friendly: Vegetal chitosan is an excellent alternative for individuals who avoid animal-based products, such as those who follow a vegan or vegetarian lifestyle.
• 2. Allergen-free: Traditional chitosan is derived from shellfish, which can cause allergic reactions in some people. Vegetal chitosan does not contain any shellfish-derived ingredients, making it an allergen-free option.
• 3. Purer: Vegetal chitosan is often considered to be purer than traditional chitosan because it is derived from a single source, whereas traditional chitosan can be contaminated with other shellfish-related substances.
• 4. Better solubility: Vegetal chitosan is more soluble than traditional chitosan, which makes it easier to incorporate into various applications such as cosmetics, pharmaceuticals, wine and food.
• 5. Improved bioavailability: Some studies have suggested that vegetal chitosan has a higher bioavailability compared to traditional chitosan, which means that it can be absorbed and utilized more effectively by the body.

Overall, vegetal chitosan offers several advantages over traditional chitosan, making it an attractive alternative for individuals and industries looking for a vegan, allergen-free, and more effective chitosan source.

3. What are the benefits, functions and dosage of vegetal chitosan in pet?

Vegetal chitosan, derived from non-animal sources such as fungi, is increasingly being explored for use in pet, including cats, dogs. Its benefits, functions, and recommended dosages in this context vary based on the intended purpose and the type of animal.
