Introduction to Chitosan Extract

Chitosan extract is derived from chitosan, a natural biopolymer that is obtained from the shells of crustaceans such as shrimp, crab, and lobster. Chitosan itself is composed of chitin, a substance found in the exoskeletons of these arthropods. Chitosan extract is produced by chemically processing and purifying chitosan.

Application of Chitosan Extract

Seed Treatment Agent
Chitosan can be used as a treatment agent for many grain and vegetable crop seeds (such as seed soaking, seed dressing, coating, etc.) to stimulate seeds to germinate in advance, promote crop growth, and improve disease resistance, thereby increasing grain and vegetable yields. Chitosan forms a protective film on the surface of the seeds, which is conducive to keeping the water in the seeds for the crops. According to foreign reports, chitosan can make the taste of tea more mellow, the cold resistance of rice is stronger, the color of tomatoes can be beautiful and the sugar content can be increased.
Soil Conditioner
Using the antibacterial ability of chitosan and the effect of improving soil, chitosan and soluble protein (such as collagen) can be used to synthesize liquid soil conditioner. The organic fertilizer can be absorbed by crops, can inhibit the growth and reproduction of pathogenic bacteria in the soil, and can effectively improve the aggregate structure of the soil, so it is an ideal liquid soil conditioner. When in use, the liquid soil conditioner sprayed on the soil surface can form a film, so it also has the effect of retaining moisture. Fertilizers or pesticides can also be infiltrated into them to make them evenly dispersed and slow-released. Chitosan in the soil can promote plant growth.
Raw Materials of Foliar Fertilizer
Chitosan was originally reported as an inducer of plant responses, as it can induce the production of phytoalexins in pea pods, as well as the production of tomato plant protease inhibitors. The increase of chlorophyll content is one of the induced responses of chitosan, and the increase of chlorophyll content is usually closely related to the promotion of plant growth or the increase of net photosynthesis rate. Chitosan is a natural plant nutrition growth promoter - the raw material of foliar fertilizer. The foliar fertilizer compounded with chitosan can not only kill insects, resist diseases, play the role of fertilizer, but also Decompose animal and plant residues and trace metal elements in the soil, so as to convert them into nutrients for plants, enhance plant immunity, and promote plant health.
Anti-Pathogen Infection
Chitosan has an inhibitory effect on the spore germination and growth of plant pathogenic bacteria, and has an induction effect on the protective mechanism of pathogen infection. At 25℃, the antibacterial effect of chitosan was enhanced with the increase of the concentration of chitosan or the degree of deacetylation. For example, seed soaking treatment can reduce the incidence of wheat sheath blight by 30%-50%, and the incidence of soybean root rot by 42%.
Induce Disease Resistance
In recent years, there have been many reports on the induction of disease resistance of chitin. For example, the degradation products of chitosan can induce chitinase activity in isolated leaves and whole plants of cucumber seedlings, and this induction can be conducted. Plants do not contain chitin and chitosan, but they have chitinase. These enzymes can react with chitin in the outer skin of plant pathogens or pests and prevent them from invading plant tissues, thereby enhancing the ability of plants to fight enemies. harmful defensive capabilities.
Nematicides
Nematodes have caused great harm to fruits, vegetables and seeded crops in recent years. Mixing chitosan with an appropriate carrier material can make a very effective natural pesticide for nematodes. It is insoluble in water and will not Contaminate groundwater. Its insecticidal effect is different from that of chemical preparations. It does not directly kill pests, but prompts microorganisms in the soil to produce an enzyme that can kill nematodes and their eggs to achieve insecticidal purposes.

Extraction of Chitin and Chitosan from Shell

Shrimps are mostly exported in frozen conditions that have undergone a process of separation of the head and skin. The crude shrimp head and skin materials have a very low economic value and are treated as bio-waste or sold to animal feed manufacturers. This industry generates large amounts of shrimp bio-waste during processing, approximately 45-55% of the weight of raw shrimp. This bio-waste can be used to produce value-added products such as Chitin and Chitosan. Chitin is extracted from shrimp shells by demineralization and deproteinization procedures. Subjecting this further to the deacetylation process resulted in synthesis of Chitosan.
Demineralization
Demineralization of shrimp shells can be carried out using HCI (concentration 2-4%) at ambient temperature (28 ± 2°C) with a solid to solvent ratio 1:5 (w/v) for 16 hours. The residue obtained was washed and soaked in tap water until neutral pH.
Deproteinization
Deproteinization of the shrimp shell was done with 4% NaOH at ambient temperature (28 ± 2°C) with a solid to solvent ratio 1:5 (w/v) for 20 hours. The residue was washed and soaked in tap water until neutral pH. Then purified chitin was dried until it became crispy. Chitin flakes were grounded to small particles to facilitate deacetylation.
Deacetylation
Removal of acetyl groups from chitin was carried out using NaOH (concentration 30% – 60%) at 65°C temperature with a solid to solvent ratio 1:10 (w/v) for 20 hours. The residue was washed until neutral pH with tap water. The resulting chitosan was then dried at cabinet dryer for 4 hours at 65 ± 5° C and further characterised.
Other methods for chitin preparation include enzymatic reactions, and microbial fermentation. Conventional chemical extraction of chitin requires strong acids and alkali to eliminate minerals and proteins. But, using these harsh chemicals is detrimental to the environment. In addition, although enzymatic reactions and microbial fermentation methods avoid this drawback, the incomplete elimination of minerals and proteins limits the application of these methods.

Tips for Chitosan Extract

When using chitosan extract as a fertilizer, it is important to follow the manufacturer's instructions and consider the specific needs of your plants. However, here are some general guidelines for using chitosan extract fertilizer:

Dilution

Chitosan extract is typically provided in a concentrated form. Dilute the extract according to the manufacturer's instructions or recommended application rates. The dilution ratio will depend on the specific product and the intended application method.

Timing and Frequency

The application timing and frequency of chitosan extract will depend on the specific crop, growth stage, and desired effects. Generally, it is beneficial to apply chitosan extract early in the growing season or during critical growth stages such as flowering or fruiting. Follow the recommended application schedule provided by the manufacturer.

Compatibility

Chitosan extract is generally compatible with most fertilizers and pesticides. However, it is recommended to conduct a compatibility test before mixing it with other products. Avoid applying chitosan extract within a short time frame of chemical fungicides or bactericides, as they may interfere with its effectiveness.
