Description

Sianchau nata

Technical field

The invention belongs to food processing technology field, be specifically related to a kind of sianchau nata with health-care efficacy, unique flavor.

Background technology

Celestial grass (Mesona Blume); Have another name called Mesona chinensis Benth, cool grass meal, firewood grass etc.; Be that the celestial grass of Labiatae belongs to the annual herb plant; Be the plant resources of the traditional medicine-food two-purpose of China, be rich in polysaccharide, pigment, ursolic acid, oleanolic acid, amyrin and flavones, pectin and phenols etc., and other trace element and vitamin.According to ancient medicine book " it is former that book on Chinese herbal medicine is asked " record, celestial grass has the effect of " clear hot summer weather, Xie Zangfu knot heat poison is controlled wine wind ", in " south of the Five Ridges gather medicinal herbs record ", puts down in writing, and celestial grass can be controlled colored willow poison to the marrow.The traditional Chinese medical science thinks, celestial grass is cool in nature cold, and slightly sweet flavor is puckery, and that chews has a colloidality, has clearing heat and promoting diuresis, cool blood relieving summer-heat, the effect of quench one's thirst Li Shui and heat extraction poison.The modern medicine assay determination thinks that ursolic acid in the celestial grass and oleanolic acid have cooling, calmness, hypoglycemic effect; Flavonoid substances has the effect that suppresses growth of cancer cells, brings high blood pressure down; Amyrin have calmness, refrigerant, quench one's thirst, the effect of Li Shui; Polysaccharose substance has the effect that strengthens and improve human body immune function; Trace element has the free radical of inhibition to form anti-ageing, anticancer effect; Support one's family to have and regulate and the enhancing physiological function.

The fine fruit of coconut palm is a kind ofly to be formed at the gel membranoid substance of liquid surface by microorganism through liquid state fermentation, and main component is a cellulose,, is commonly called as in south east asia " Natta " " coconut palm really " or " high fibrous coconut " in the trade name in continent and Taiwan.The large-scale production of bacteria cellulose mainly is to utilize nutritious natural substrates such as coconut water, pineapple juice as culture medium production at present, and the acetobacter that inoculation can be produced fiber obtains after fermenting, and the production cycle is generally about 7 days.Fine fruit is applied in the extensive various food as foodstuff base material or food additives coconut palm.The physiology mediation function of dietary cellulosic comprises in the fine fruit of at present known coconut palm: promote enterogastric peristalsis, prevent constipation, improve human consumption function etc.The research of Japan shows that the fine fruit of coconut palm has the function of beauty treatment, fat-reducing.Philippine university research personnel find that coconut palm really has protective effect on cancer risk, often eat and can reduce carcinogenic substance to chromosomal destruction, help carcinogenic people's anti-cancers such as those contact cigarettes, automobile exhaust gas especially; Also but prevention of cardiac makes the human immune system exempt from destruction, and antibiotic lipids is provided.Also have simultaneously research to show, the fine fruit of coconut palm also has positive effect as a kind of biological polyoses to preventing the human body angiocardiopathy.Because the plain gel characteristic of the fine fruit fiber of coconut palm, high water retention characteristic and fully not by the characteristic of human consumption make it to become a kind of foodstuff base material of very attractive.It is to find one of classic dietary fiber at present, and it can be used as as food forming agent, thickener, dispersant etc. in textured vegetable protein, artificial fish, sausage, the ham sausage; It can join in the ice cream the anti-melting that improves product, improve mouthfeel; It can be used as skeleton of casing and some food or the like.

The fine gel that really is white in color of coconut palm pure, not dehydration, high resilience, free from foreign meter, insipidness generally is referred to as " the fine plain fruit of coconut palm ".Because the fine fruit of coconut palm has unique cellulose network structure, this structure can be through physical absorption, with the material of giving the fine fruit of coconut palm local flavor by element fruit surface seepage in the cellulose network of inside, so just given coconut palm fine plain really various in riotous profusion colors and local flavor.This post-processing coir and fruits flavor gives way, mainly through the prime of fructose, dyeing, Flavorings, etc. Process implementation, such as literature, "the development of high-fiber coconut jelly" ("Food Industry" 2006 Part 2 period) discloses a casual healthy food as fruit jelly coconut fiber production process, is to coir and fruits through mashing, boiling gum obtained after treatment with a sweet and sour taste of the product.Yet the mode of this post processing, its mechanism mainly are through physical absorption, and the processing time is generally longer.In addition; Because adopt the mode of physical absorption; The fine fruit of reprocessed coconut palm exists under the situation in factor such as be heated, pH value changes, and permeates in the material of the plain network internal of the fine fruit fiber of coconut palm and desorb can take place and to external diffusion, the result has caused the unsettled situation generation of product performance.

Also useful fruit juice is produced the fine fruit of coconut palm as culture medium direct fermentation, obtains to have the fine fruit product of coconut palm of certain local flavor then.Be raw material as disclosing the concentrated kiwi-fruit juice of a kind of utilization in the document " development of Kiwi berry Natta " (" pesticide herd product exploitation " the 2nd phase in 2000); Leave standstill the method that cultivating and producing has gone out Kiwi berry " Natta " (being the fine fruit of Kiwi berry coconut palm) through acetic acid bacteria; Its finished product is a light green color; The gel thick film, the smooth delicacy of mouthfeel and flexible, and have the distinctive fragrance of Kiwi berry.Yet this mode of production receives than limitations: the one, and fresh Juice raw material is difficult to preserve, and easy pollution causes rotten, and the technology through sterilization can make again that trophic factors loses with flavour factor in a large number in the fruit juice, causes quality decline; The 2nd, with the production culture medium of fresh fruit of vegetables juice, might not be fit to produce the growth of cellulose bacterial classification, thereby cause fermentation period long as the fine fruit of coconut palm, increased production cost.Fermentation period like report in: the document " development of Kiwi berry Natta " reaches 10-15 days, about cellulose thickness 2cm, and adopt at present coconut water or pineapple water as the fermentation medium fermentation period only about 7 days, cellulose membrane thickness just can reach more than the 2cm; The 3rd, be raw material with fresh fruit of vegetables juice; Inserting acetobacter ferments; Flavor substance in the Juice is utilized by microorganism on the one hand and loses; Materials such as the small molecule aldehyde that metabolism produces in the sweat, volatile acid also can produce bad smell and shelter original flavor substance, thereby make the fine fruit of coconut palm after the fermentation be difficult to reach the expection local flavor.
