Abstract
The invention discloses a method for extracting jerusalem artichoke synanthrin and nanometer dietary fiber with ultrahigh pressure, belonging to the field of food processing. The method comprises the following steps of: taking fresh jerusalem artichoke as raw material, mixing the jerusalem artichoke with water and pulping, extracting under high pressure, filtering, centrifuging or filtering in a pumping way to obtain extracting liquid; decolorizing the extracting liquid with active cable, concentrating by means of pressure reduction and spray drying to obtain solid synanthrin powder; and processing the residual after exacting the synanthrin by means of wet type ultramicro smashing and nanometer milling smashing to obtain nanometer level dietary fiber. The method has the benefit effects of having the characteristics of short time, low energy consumption and high extraction rate when extracting the synanthrin. The active ingredients of the extracted residual can be better remained and can be further processed to be the dietary fiber with oxidation resistance. The method can simultaneously obtain two products with high additional values, does not discharge the solid waste, can sufficiently use the jerusalem artichoke, and finds a use pathway for the comprehensive exploitation of the deep processing of subsidiary agricultural products.
Description
Technical field
The present invention relates to a kind of method of from jerusalem artichoke, extracting synanthrin and preparing food fibre, belong to field of food.Utilize superhighpressure technology to extract the method for synanthrin in the jerusalem artichoke, and remaining residue prepare nano-dietary fiber after utilizing the extraction synanthrin.
Background technology
Jerusalem artichoke (Jerusa lemartickoke L.) another name Jerusalem artichoke, Jerusalem artichoke, ginger, be composite family Helianthus annual herb plant.Its underground stem tuber is fine and closely woven, clear and melodious, both can stir-fry and eat, and can pickledly eat again, also can dry to wear into powder and replace general plant amylum.Contain abundant synanthrin in the jerusalem artichoke, can pass through products such as separation and Extraction synanthrin, oligofructose.Synanthrin mainly is to be a kind of Polylevulosan that glycosidic link is formed by connecting by β-(2 → 1) fructosyl-fructose, and its fructosyl unit (is the polymerization degree, DP) does not wait from 2 to 70.Synanthrin has the effect of superpower propagation human body bifidus bacillus, it is functional substance to the human body beneficial, for regulating organism balance, recover gastrointestinal function, enhance metabolism, prevent various diseases, safeguarding that HUMAN HEALTH has very important effect, and synanthrin is as the edible polysaccharide of a kind of natural function, physiological function with water-soluble dietary fibre and biological activity precursor can be applied in low in calories, low sugar, the low fat food.
At present, pay much attention to the extraction and the application of functional food additives synanthrin both at home and abroad, the extraction of synanthrin is reported that mainly based on the water extraction technology ultrasonic wave and microwave auxiliary extraction technology are also arranged.The applying high voltage technology is extracted the existing report of effective constituent in the crude substance, but does not see the report that adopts pressure technique to extract Girasole synanthrin.
Jerusalem artichoke residue behind the extraction synanthrin contains rich dietary fiber, mineral element and polyphenols, and the protein that contains, fat and starch are seldom, are fit to further be processed as the food fibre with oxidation-resistance.But the jerusalem artichoke residue that extracts at present behind the synanthrin goes out of use usually, causes a large amount of wastes of resource.On the other hand, adopt the activeconstituents of thermo-sensitivity such as Polyphenols in the residue behind the water extraction synanthrin to be destroyed, lost the physiological active functions that much should have by high temperature.And ultra-high voltage low temperature can be avoided the loss and the destruction of some heat-sensitive substances (as phenolic compound), preferably some physiological active functions of retaining food product.
Summary of the invention
The method that the purpose of this invention is to provide synanthrin in a kind of ultra-high voltage rapid extraction jerusalem artichoke, and utilize the residue behind the extraction synanthrin to prepare nano level anti-oxidant food fibre.
The present invention adopts following technical scheme to realize: a kind of method of utilizing ultra-high voltage to extract Girasole synanthrin and nano-dietary fiber, with fresh jerusalem artichoke is raw material, mix making beating with water after, be transferred in the high-pressure reactor, add a certain amount of water according to solid-liquid ratio, after soaking certain hour under the room temperature, under certain pressure, keep certain hour, release, after filtration, centrifugal or suction filtration obtains extracting solution, and repetitive operation merges the extracting solution that twice filtrate promptly obtains synanthrin, adopt decolorizing with activated carbon, obtain solid synanthrin powder through concentrating under reduced pressure and spraying drying then.
Carry out wet type micronizing and nano ball grinding respectively and pulverize extracting residue behind the synanthrin, obtain nano-grade dietary fibers after spray-dried.
The concrete operations step is as follows:
A, with bright jerusalem artichoke and water by weight making beating in 1: 2, transfer to then in the high-pressure reactor, adding water to solid-liquid ratio is 1: 10-1: 20 the jerusalem artichoke slurries;
B, will leave standstill 15-20 minute under the jerusalem artichoke slurries room temperature, plus-pressure keeps release after 3-10 minute to 200MPa-600MPa then;
C, the extract slag that obtains after autoclaving slurry separated obtain synanthrin extracting solution and residue;
D, with residue and water with mass ratio 1: 5-1: 10 mix, and b and c repeat to extract once set by step in high-pressure reactor;
E, merging extracted twice liquid; In extracting solution, add the activated carbon decolorizing of fresh jerusalem artichoke quality 0.5%-0.8%, cross leaching filtrate;
F, filtrate is made the synanthrin concentrated solution at 50-60 ℃ of following concentrating under reduced pressure, decompression pressure 0.01MPa-0.09MPa;
G, with the synanthrin concentrated solution 120-200 ℃ of spraying drying, make solid synanthrin powder product;
H, the residue that will extract behind the synanthrin carry out the wet type micronizing with colloidal mill, and operate continuously 2-5 time obtains the micron order material;
M, press mass ratio adds 0.3%-1% in the micron order material sucrose ester or sorbitol monostearate, adopt nanon ball-mill to pulverize 5-12 hour, obtain nano-grade dietary fibers after the spraying drying.
The present invention has expanded the Application Areas of ultra-high voltage, and a kind of novel method of extracting synanthrin and preparation nano-dietary fiber of uniting is provided.It is higher to have yield, and cost is low, and the advantage of breed bacteria not can solve traditional water and extract extraction temperature height, extraction time is long and water consumption is big problem.The synanthrin that the present invention extracts can directly apply to functional foodstuff and medicine field after making with extra care.Extra-high tension unit all has sale on market, do not have technical bottleneck, realizes industrialization easily.Ultra-high voltage extracts and has not only improved the yield of synanthrin, and can keep the physiologically active of original composition.Therefore the food fibre of the jerusalem artichoke residue preparation behind the utilization extraction synanthrin has higher anti-oxidant activity.Whole technological process environmental friendliness, no unnecessary solid waste is discharged, and can make full use of existing agricultural resource.
The invention has the beneficial effects as follows: adopt superhighpressure technology lixiviate synanthrin at normal temperatures, can cut down the consumption of energy on the one hand, shorten extraction time, reduce the consumption of lixiviate number of times and water, help the further processing of extracting solution, reduce discharge of wastewater simultaneously; Ultra-high voltage also has sterilization functions in addition, can simplify production technique, reduces production costs.Avoid the loss and the destruction of some heat-sensitive substances (as phenolic compound), preferably some physiological active functions of retaining food product.
