What is Alpha Chitin?

Chitin is a nitrogen-containing polysaccharide, in addition described as chitin, chitin, covering healthy and balanced protein, chitin, clear cutin, along with extra. It is the 2nd most abundant biopolymer in nature in addition to is thoroughly distributed. Especially the essential elements of the therapies of arthropods such as shrimps, crabs, pests, and so on. Shrimp therapies have about 15% to 30%, and in addition crab therapies consist of worrying 15% to 20%. It is furthermore an important part of the cell membrane layer of decreased plant fungis, as well as also additionally it is also contained in lichens, environmentally friendly algae, yeast, jellyfish in addition to furthermore squid. It is estimated that the annual biosynthesis quantity surpasses 1 billion numbers, which is a significant renewable energy. The look is white or yellow-colored clear body, which is a polymer of 2-acetylglucosamine. Its chemical structure appears like that of all-natural cellulose. Together with the hydroxyl group, the bit similarly includes acetamido along with additionally amino important groups, which can be taken advantage of for developing change. It has different teams in addition to has far more helpful structures than cellulose along with its by-products. It is insoluble in water, ethanol, ether, salts, thin down acids and likewise damages antacid; it can be liquified in acetic acid in addition to responded with concentrated caustic soda option to create a refined colloid. Soluble chitin (additionally called polyaminoglucose, chitosan, sugar liquid chitin, chitosan, and also extra), they can be made use of for: ① ion exchange material for washed water as well as on top of that extraction of uranium from salt water; ② gel chromatography column ③ preparation job of foods packaging motion picture or soluble in vivo clinical strings that can be broken down by biology or enzymes; ④ water retention representative for increasing plants or germs; ⑤ anti-shrinkage and also anti-wrinkle therapy of materials, straight color or sulfur color Strong color.

Alpha Chitin is insoluble alike acids together with bases, along with its chemical frameworks are truly protected, which is an essential factor that it has in fact not been created for an extended period of time. After deacetylation, chitosan is white to light yellow powder, although it is insoluble in water, alkali solution as well as additionally all-natural solvent, it is soluble in thin down acid choice, consisting of not natural thin down acid (hydrochloric acid, nitric acid, along with much more) In addition to likewise thin down natural acids (acetic acid, lactic acid, formic acid, ascorbic acid, malic acid, etc). In the liquid choice of polyvalent all-natural acids such as citric acid along with additionally tartaric acid, it liquifies when heated up at heat, along with additionally ends up being gel when the temperature degree decreases.

Alpha Chitin is the β( 1 → 4) Polymer, ie chitosan. Numbers 2-7 reveal the chemical frameworks of chitin, chitosan along with cellulose, which are equivalent in framework amongst the 3. Given that the existing modern growth can not completely deacetylate chitin right into 100% chitosan, in addition to it is tough to definitely split both, the existing chitosan items are usually a mix of chitin in addition to in addition chitosan, yet the chitosan web product is needed to be above 60%. Nonetheless, chitosan as a sensible food base needs a chitosan item of more than 85%.

Application of Alpha Chitin in Agriculture

Alpha Chitin fertilizer, commonly known as chitin fertilizer, has been widely used in agriculture and has been widely recognized by growers and consumers. Chitin fertilizer has the following characteristics:

1. Alpha Chitin can stimulate plant growth and increase the yield of crops and fruits and vegetables.

2. Alpha Chitin can effectively reduce pesticide residues. In the past, Chinese tea and Ningxia wolfberry were basically unable to be exported due to excessive pesticide residues. Through the use of chitosan oligosaccharides in Tieguanyin tea and Ningxia wolfberry, it was found that chitosan oligosaccharides can effectively decompose organophosphorus pesticides on tea and Ningxia wolfberry. Pesticide residues to meet export standards.

3. Alpha Chitin can increase the sweetness and reduce the acidity of the fruit. After using chitosan oligosaccharides in the growth process of apples, pears, grapes, etc., various indicators show that the acidity of apples, pears, grapes, and navel oranges has decreased, the sweetness has increased significantly, and the content of vitamins has increased by nearly 3-6 times.

4. In terms of green farming, while replacing antibiotics, Alpha Chitin can increase the high-density lipoprotein of animals, reduce its cholesterol and triglyceride content, and become a low-fat food, which is not only safe but also healthy. Chitosan oligosaccharide eggs not only greatly reduce cholesterol, do not contain antibiotics, and the content of lecithin is increased by 100%, and the antibacterial and antioxidant properties are enhanced, which prolongs the preservation period of eggs.

2. The application of chitosan oligosaccharides in biopesticides
Alpha Chitin, as a biological pesticide, namely amino oligosaccharin, was founded by researcher Wang Shikui in 1996. After nearly 20 years of development, amino-oligosaccharide fungicidal pesticides have been popularized and applied on a large scale in my country.

(1) Function
1. Induced fungicides
The antibacterial mechanism of amino oligosaccharin is: under acidic conditions, -NH+3 in the amino oligosaccharin molecule dissociates from the silicic acid and phospholipids contained in the bacterial cell wall to combine with anions, thereby hindering the proliferation of bacteria; then, the amino oligosaccharide Saccharin is further reduced in molecular weight and enters the microbial cells through the cell wall, hindering the transcription process of genetic factors from DNA to RNA, resulting in the complete inability of microorganisms to reproduce.

Therefore, amino oligosaccharins can inhibit the growth of some pathogens, affect the germination of fungal spores, induce changes in the morphology of mycelia, and changes in the biochemistry of the spores.

Amino oligosaccharins can be widely used to prevent diseases caused by viruses, bacteria and fungi of fruit trees, vegetables, underground rhizomes, tobacco, Chinese medicinal materials and grain and cotton crops, such as: mosaic disease, small leaf disease, spot disease, anthracnose, frost Mildew, blight, blight, yellow dwarf, rice blast, bacterial wilt, soft rot and other diseases.

2. Plant growth regulator
Amino oligosaccharins can be used as plant function regulators, which have the functions of activating plant cells, promoting plant growth, regulating the closing and opening of plant resistance groups, activating plant defense responses, and initiating the expression of disease resistance genes. Japan has made amino oligosaccharins into plant growth regulators to increase the yield of some crops. Experts have studied the promoting effect of amino oligosaccharins on cucumber growth, and the results show that cucumber plants treated with amino oligosaccharins not only have enhanced resistance to downy mildew, but also can advance the fruit harvest period by 3 to 5 days, and the yield Significantly improved.

3. Seed coating agent
As a plant growth regulator and antibacterial agent, amino oligosaccharin can induce plants to produce PR protein and phytoalexin. The new seed coating agent developed with amino oligosaccharin as the basic component has great production potential.

Research on the application effect of amino oligosaccharide rapeseed coating formulation, with chitosan oligosaccharide as the basic component, mixed with chemical fertilizers, trace elements and preservatives and other ingredients, prepared into a relatively stable colloid solution and then seed dressing, the effect on rapeseed Seed germination and emergence have no obvious effect, but it can promote the growth of rapeseed, increase the rate of strong seedlings, and increase the yield. The yield increase ranges from 4.33% to 9.67%. Amino-oligosaccharidin seed dressing can significantly inhibit the occurrence of Sclerotinia sclerotiorum, and the control rate of the three rapeseed varieties is 34.19%-44.1%.

4. Crop stress resistance agent
Amino oligosaccharins have good effects on crops’ cold resistance, high temperature resistance, drought and flood resistance, salt and alkali resistance, fertilizer damage resistance, air damage resistance, and nutritional imbalance resistance. This is because oligosaccharins have good effects on the crop itself and the soil environment in many aspects. For example, among the various resistant substances induced by oligosaccharins in crops, some have the ability to prevent, alleviate or repair the adverse effects on plant cells. Harmful effect; another amino oligosaccharin can promote the growth of crops robust, robust plants naturally have a strong ability to resist stress.

Studies have shown that amino oligosaccharins can induce the burst of reactive oxygen species in strawberry cells, and can also induce the increase in the activity of active oxygen scavenging enzymes. Therefore, treatment of strawberry cells with amino oligosaccharins can induce resistance reactions.

Agricultural technology experts have found in practice that: when crop seedlings are wilted due to low temperature and cold damage, the plants will quickly recover after timely application of amino oligosaccharides; Vigorous new roots; when the crops suffer from pesticide damage and the branches and leaves wither, the application of amino oligosaccharins can assist in detoxification and make them quickly pull out new branches and leaves.

Alpha Chitin Production Method

Approach 1. The manufacturing method using shrimp and also crab treatments as resources
Clean the treatments of shrimps and also crabs, completely dry them, crush them, respond with excess 2mol/L hydrochloric acid service (1:10) for 4-5h, filter, afterwards reward with 2mol/L hydrochloric acid at worrying 0 ° C for 12-20h, filter, Tidy to neutral.
Shrimp as well as likewise crab coverings [2mol/LHCl] → [0 ° C, 12-20h] stress solids
Use an added of 50-100g/ L (5% -10%) salt hydroxide or potassium hydroxide remedy (1:8) for alkaline treatment for 3-4h, and regulate the temperature level at 90-95 ° C. Acid as well as alkali treatment can be copied 1-2 times to remove calcium carbonate, phosphate, healthy protein and additionally pigment.
Solid [NaOH] → [3-4h, 90-95 ℃] get rid of the solid
[HCl] → solid [NaOH] → the solid was cleaned with an appropriate quantity of outright ethanol and also ether, as well as dried under decreased pressure to obtain chitin as a white strong. Business production can be washed with water as opposed to organic solvents. The yield is 20% for shrimp treatments and additionally pertaining to 15% for crab shells.
Strong [outright ethanol, ether] → chitin completed thing
Take chitin and also consist of 400-450g/ L (40% -45%) salt hydroxide solution (1:15 -20), react at a temperature level of concerning 110 ° C for 1h, filter, and also tidy with water until neutral. According to the needs of various degrees of deacetylation, repeat the treatment 1-2 times, and also completely dry under lowered stress to obtain completion item. The degree of deacetylation reaches 60% -99%. Throughout the deacetylation process, due to solvation, some glycoside bonds are hydrolyzed, creating a reduction in the liked one molecular weight. To avoid the devastation of macromolecules, methods such as including 10g/L (1%) salt borohydride (NaBH4) treatment or passing inert gas are tackled, such as putting chitin in 400g/L (40%) salt hydroxide choice, React at 110 ° C for 2.5-3h to acquire chitosan.
Chitin thing [NaOH] → [110 ℃,1 h, pH7] chitin
Method 2: Prep work with snail covering as resources
The snail coverings were cleaned up, dried, and additionally grated, and additionally sieved via an 80-mesh screen to get snail shell powder for later usage.
Take 400 g of snail powder, consist of 1 mol/L hydrochloric acid 10 times that of the raw item, stir at room temperature level for 1 day, filter, clean the deposit with water till neutral, dry, in addition to repeat the above procedure twice to obtain desalted snail powder (71.5 g). Take desalted snail shell powder and also add 8 times the amount of 2.5 mol/L salt hydroxide solution, mix for 24 hr, filter, along with entirely dry to obtain chitin (59.8 g). The return has to do with 15%. Liquify chitin in 50% salt hydroxide service, keep comfy at 130-140 ° C for 2 humans resources, filter, clean with water up until neutral, and also more deacetylate to get chitosan.
Technique 3, the preparation strategy taking the pupa covering as raw material
Take the pupal skin of the silkworm moth after advancement, completely dry it at 60 ° C, add an equivalent quantity of petroleum ether to fertilize and also degrease. Consist of 3 times the quantity of 3% hydrochloric acid to the defatted pupal skin, as well as decalcify at area temperature for 12 hrs. Include 30g/L (3%) sodium hydroxide solution to the decalcified pupal skin, boil for 3-5 humans resources, and afterwards remove the healthy protein to obtain beige chitin. Take chitin and also consist of 420g/L (42%) salt hydroxide remedy (include a percent of NaBH4), boil, filter every 2h, tidy with water, replace with brand-new lye once, proceed deacetylation up until 8h, filter, clean with water up until Neutral, dry naturally to get white chitosan. The return is 10%-13%, the level of deacetylation can get to 91%, the natural viscosity is 790-890ml/ g, as well as also the loved one molecular mass is 0.81 × 106-1.34 × 106.
The prep work of chitosan with low relative molecular mass handles hydrogen peroxide damage method, as well as the numerous focus of hydrogen peroxide as well as feedback time are managed to prepare chitosan with loved one molecular mass varying from 4.31 × 104 to 1.32 × 104. The operation is simple, takes much less time, as well as does not require special reagents in addition to tools.
