There is no obvious odor, but in some cases, there may be a slight plastic odor. Has high hardness and can withstand significant pressure and friction. Insoluble in water, but partially soluble in certain organic solvents such as alcohols, ethers, esters, etc. It is an insulator that does not conduct electricity. It can have different levels of transparency, from completely transparent to semi transparent or opaque, depending on the additives and process conditions used in its manufacturing process. Has good mechanical properties, such as high strength, wear resistance, etc.
Xylan, a heterogeneous polysaccharide, serves as a crucial component of plant hemicellulose. It accounts for approximately 15% to 35% of the dry weight of plant cells, making it a significant contributor to plant cell walls. Xylan's main chain consists of β-D-xylopyranose units linked by 1-4 glycosidic bonds, often with short side chains attached at varying degrees. These side chains may include O-acetyl groups, α-L-arabinofuranose residues, α-D-glucuronopyranosyl units, and 4-O-methyl-α-D-glucuronopyranosyl groups.
Xylan is found in the cell walls of plants, interacting with other components of lignocellulosic materials to varying degrees. One such interaction is the covalent bond between xylan's arabinose residues and glucuronosyl groups with lignin, mediated by phenolic residues like ferulic and coumaric acids.
Xylan was produced by modern bioengineering technology and purified. The activity of the product was derived from the selected Trichoderma and obtained by genetic engineering transformation, fermentation and extraction. The range of action pH was 3.5 – 6.5, and the optimum pH was 5.0 ; the temperature range was 50 – 60 °C, and the optimal temperature was 55 °C. Specific optimum conditions should be determined according to the manufacturer ' s process. XYLAN has n-phenylpropane on the n-propyl side chain β On site binding of two molecules β,γ- The general term for substances with a diphenylmethylbutane backbone, therefore it has a basic skeleton composed of two C6-C3 units. This is the name proposed by R.D. Haworth (1936). The benzene ring can be replaced by hydroxide, methoxy, or methylenedioxy groups, and the side chains often have a cyclic structure. Widely distributed in flowering plants, it often exists in glycosides or free states in bark, fruit, wood, leaves, roots, and resin extracts. There are now over 50 known species, including highly toxic podophyllotoxin, Coriamy rutin from the family Moriaceae, and non-toxic dihydroguaiac acid, which can be used as a food oxidation preservative. It is the main hemicellulose component in plant cells, accounting for 35% of the dry weight of plant cells. It is a rich biomass resource and the most abundant polysaccharide in nature besides cellulose. However, a significant portion of xylan in nature is not effectively utilized, resulting in significant resource waste. The structure is a type of poly pentacarbon sugar, composed of β- D-1,4 xyloside bonds are linked together and carry multiple substituents. Partial degradation of xylan can form oligosaccharides, while complete degradation yields five carbon monosaccharides: xylose, ferulose, arabinose, etc., with xylose being the main component.
Xylan powder is the most abundant hemicellulose component in plant cell walls, accounting for over 35% of plant dry weight. It forms the main chain by connecting xylose units through β -1,4-xylose glycosidic bonds, and carries side chains such as arabinose and glucuronic acid. Its unique chemical structure endows it with extensive application value, covering food, medicine, industry, agriculture, feed, cosmetics, and emerging fields. The following elaborates on its purpose from multiple dimensions:
1. Dietary fiber reinforcement
Xylan, as a source of dietary fiber, can significantly enhance the nutritional value of food. For example, arabinoxylan (a type of xylan) is recognized by the FDA as dietary fiber, and the European Union allows its addition to food (recommended daily intake ≤ 15 grams). Its insoluble fiber properties promote digestive health and reduce the risk of constipation and diverticular disease by maintaining the balance of gut microbiota. A 2012 study in the British Journal of Nutrition showed that consuming 1000 milligrams of wheat bran rich in arabinoxylan per day significantly reduced the frequency and severity of constipation after three weeks.
2. Food additive
Stabilizers and thickeners: Xyloglycans increase food viscosity and improve texture through hydrogen bonding. For example, adding 0.5% -2% xylan to baked goods can enhance dough elasticity and make bread softer; Adding 0.1% -0.5% to beverages can improve stability and taste.
Leavening agent: Xylan decomposes and releases water during the baking process, delaying starch gelatinization, and is used as a sugar substitute to make low sugar, high fiber biscuits.
Moisturizing agent: Its high water retention can prevent food from drying out and extend shelf life, such as when used in meat processing to keep meat fresh and tender.
3. Functional food development
Blood glucose management: Xyloglycans reduce postprandial blood glucose fluctuations by delaying gastric emptying and inhibiting starch digestive enzyme activity. In 2016, the European Journal of Nutrition confirmed that patients with diabetes who ate arabinoxylan fortified bread before going to bed had significantly improved insulin sensitivity the next day.
Weight control: Xyloglycans increase satiety and reduce calorie intake. The 2011 PLoS One study showed that mice fed a high-fat diet supplemented with arabinoxylan had reduced body weight and adipose tissue, as well as decreased cholesterol and inflammation levels.
Probiotic effect: Xylan powder promotes the proliferation of beneficial bacteria such as bifidobacteria and improves the structure of gut microbiota. Its long-chain structure is degraded by specific enzymes at the back of the intestine to avoid discomfort such as bloating, and a daily intake of ≤ 15 grams is safe.
4.Food packaging
The low oxygen permeability and high light transmittance of xylan make it an environmentally friendly packaging material. For example, films based on xylan can isolate oxygen, extend food shelf life, and reduce plastic usage.
1. Drug delivery system
Xyloglycans are used as drug sustained-release carriers due to their strong hydrophilicity and high water retention capacity. For example, it can combine with drugs to form gel, control drug release rate and improve bioavailability. Research has shown that xylan nanoparticles can target the delivery of anticancer drugs and reduce damage to healthy tissues.
2. Bioactive ingredients
Antioxidant and anti-inflammatory: Xylan exerts a protective effect by clearing free radicals and inhibiting inflammatory factors such as IL-6 and TNF - α. For example, arabinoxylan derived from Indian millet has extremely strong free radical scavenging ability due to its presence of phenolic acids such as ferulic acid.
Immune regulation: Xyloglycans can stimulate NK cell activity and enhance immune defense. Preclinical studies have shown that it increases insulin sensitivity and triggers satiety hormone secretion by activating the GPR43 receptor signaling pathway.
3. Disease adjuvant therapy
Diabetes management: Xylan helps control blood sugar by delaying sugar absorption and improving glucose tolerance. For example, in patients with type 2 diabetes, after supplementation with arabinoxylan, insulin sensitivity increases and blood glucose fluctuation decreases.
Cardiovascular health: Xylan lowers cholesterol levels and reduces the risk of atherosclerosis. Animal experiments have shown that it can reduce the oxidation of low-density lipoprotein (LDL) and protect endothelial function.
1. Production of biofuels
Xylan, as a second-generation biofuel raw material, is converted into xylose through enzymatic hydrolysis and further fermented to produce ethanol or butanol. For example, overexpression of xylanase in transgenic poplar trees reduces wood resistance to degradation, increases saccharification efficiency by 210%, and significantly increases biofuel production.
2. Oil extraction
Xyloglycans, as drilling fluid additives, improve crude oil recovery through thickening and stabilizing effects. Its dosage is usually 0.05% -0.2%, which can withstand high temperature and high pressure environments and reduce formation damage.
3. Textile and Paper Manufacturing

The process of biosynthesis of xylan is a complex and delicate one, involving the involvement of a series of biological enzymes. Xylan is one of the main components of plant cell walls, providing the necessary energy and substances for many biosynthetic processes.
1
Plants absorb water and minerals from the soil and convert solar energy into chemical energy through photosynthesis, synthesizing glucose. This process involves the photosynthetic system and a series of enzyme reactions in chloroplasts.
2
Glucose is converted into xylose within plant cells. This process requires catalytic reactions from multiple enzymes, including hexokinase, a series of enzymes in the pentose phosphate pathway, and xylitol dehydrogenase. Xylose is one of the main monosaccharides of xylan, which plays a crucial role in the synthesis process.
3
Xylose further participates in the synthesis of xylan. This process is carried out in the plant cell wall and involves a series of biosynthetic enzymes, such as xylotransferase, xylosidase, etc. These enzymes are able to connect xylose in a specific way, forming the complex structure of xylan. During this process, plant cells will also add other components, such as arabinose, glucuronic acid, etc., to form a more complex plant cell wall structure.
In addition, the process of biosynthesis of xylan is also influenced by plant growth environment and gene expression. For example, when plants are subjected to environmental pressures such as drought, salinity, pests and diseases, they can alter the synthesis and composition of xylan to improve their adaptability and survival ability. Meanwhile, the gene expression of plants can also affect the synthesis of xylan. Through genetic engineering technology, the synthesis and composition of plant xylan can be changed, thereby creating plant materials with special properties.
The process of biosynthesis of xylan is a complex and delicate one, involving the involvement of multiple biological enzymes and the influence of plant growth environment and gene expression. By gaining a deeper understanding of this process, we can better understand the growth and development mechanisms of plants, and use this knowledge to create plant materials with special properties. Meanwhile, by studying and utilizing the process of biosynthesis of xylan, it is expected to provide new ideas and approaches for the production of biodegradable plastics and other environmentally friendly materials.
