Description

A kind of production line of richness polyphenol nigecose

Technical field

This utility model is related to sugar refining technology field, specifically a kind of production line of richness polyphenol nigecose.

Background technology

Sugar Industry is Guangxi mainstay of the national economy industry, is the comprehensive industry being related to secondary and tertiary industries, near in area The productive life of half population is closely bound up with Sugarcane Industry, Shi Wo area's fiscal revenues and minority area, border area agriculture The main support that people's employment increases income.In recent years, due to being affected by international sugar valency, sugared valency constantly drops.In addition production cost is high, Agriculture as the foundation of the economy is weaker, mechanization degree is low, and the varities of industrial products single, lack the market competitiveness the problems such as, make Guangxi Sugar industry has gone to life-and-death crossroad.Having put into effect a series of policies for this Guangxi district government promotes Chinese Sugar Industry transition to rise Level,《With regard to promoting the overall plan of Chinese Sugar Industry starting new undertaking》, clearly propose " with Caulis Sacchari sinensis multiformity industry as handgrip, to accelerate The development non-sugar product of Caulis Sacchari sinensis, strengthens the industry ability to ward off risks ", conscientiously improve the Chinese Sugar Industry capability of sustainable development and international competition Power.

It is the deeper brown sugar of color in nigecose original idea, due to the approximate black of color, thus nigecose is referred to as by Japan and Taiwan, China's Mainland claims brown sugar.Nigecose is not through highly refined, decolouring sucrose.In addition to heat energy is provided, also contain many on a small quantity Aldehydes matter and multiple essential amino acid, growth in humans develops indispensable malic acid, riboflavin, carotene, nicotinic acid And trace element, such as calcium, potassium, ferrum, magnesium and Folic Acid and other mineral etc., there is very high nutritive value, and be conducive to Acid-base balance in human body.

After traditional nigecose production method is mainly sugar cane crushing, to seething with excitement, now impurity can be with bubble for heating sugarcane juice Produce and float, skim upper strata scum silica frost, and carry out stepped evaporation concentration, after being concentrated to certain brix, cooling down and stirring stimulates Crystalline substance, forms lamellar sugar or powdered sugar.But traditional nigecose production technology is because clarifying efficiency is relatively low, and leads to the impurity of nigecose product Content is higher, turbid phenomenon after being dissolved in the water；And this conventionally produced less efficient it is difficult to realize industrial metaplasia Produce.

Polyphenol compound, refers to the general name having the plant component of several phenolic hydroxyl group in molecular structure, including phenol Acid and flavone compound.Polyphenol compound has certain oxidation resistance, has listed Natural antioxidant category in, is excellent Good hydrogen or the donor of electronics, lead to peroxidation can be produced 26S Proteasome Structure and Function damage superoxide anion and hydroxyl from Obvious scavenging action is had by free radicals such as bases.Oxidative damage is to lead to many chronic diseases, such as cardiovascular diseasess, cancer and old and feeble Major reason.The anti-oxidation function of polyphenol can play preventive effect to these chronic diseases.A large amount of pigment things are contained in Caulis Sacchari sinensis Matter, these materials belong to polyphenol compound and flavonoidss, and the content of polyphenols is compared with many fruit or vegetable Go even farther.Polyphenols extract in Caulis Sacchari sinensis has stronger removing free radical, antioxidant activity, the battalion to the mankind Foster, healthy and diseases prevention and treatment are significant.There are some researches show, the polyphenols containing in Caulis Sacchari sinensis, belong to water colo(u)r, Carbon skeleton for C6-C3-C6, all has plural hydroxyl on phenyl ring simultaneously, common are 3 classes：I.e. anthocyanidin, spend Huang Plain (flavonoid), catechin.Research according to Haier's base Ovshinsky and Clarke measures：Polyphenol compound in Caulis Sacchari sinensis focuses mostly on Sugarcane taper near growing point divides.The high molecular polyphenol compound of molecular weight more than 5000 is in the distribution of full bar Caulis Sacchari sinensis For：Sugarcane leaf accounts for 33%, the sugarcane tip (0～11 section) and accounts for 37%, though the sugarcane stem after topping only accounts for 30% it is seen that the sugarcane tip is only the little of sugarcane stem Part, but Polyphenols thing then ratio more than sugarcane stem, and Relatively centralized.Caulis Sacchari sinensis in juice-extracting process, these water-soluble polyphenols compounds Major part enters in Caulis Sacchari sinensis juice.

Therefore, when to carry belt leaf Caulis Sacchari sinensis as raw material, after squeezing the juice, it is used for producing nigecose product, process is using efficient The peace and quiet sugarcane juice of membrane separation technique, can effectively improve the quality of nigecose；Multistage Membranes parallel processing sugarcane juice is enriched with polyphenols Produce nigecose technique, can effectively improve nutritive value and the functional importance of nigecose.Meet modern people to feature Nutraceutical demand；Also comply with diversified, the high-valued requirement of development cane products simultaneously, be that developing Sugarcane Industry develops new road The embodiment in footpath.
