Abstract

The present invention discloses a production method for honeybee sea buckthorn fruit juice drink. The "bentonite - gelatin - silica sol" mode flocculation method is not suitable for producing sea buckthorn clear juice for two general reasons. One reason is that the adding "order" of bentonite and gelatin should be discussed. In the fruit juice, bentonite shows a negative charge and the gelatin shows a positive charge, but the pectin widely existed in sea buckthorn fruit juice mostly shows negative charge. Therefore, adding bentonite first is unfavourable to the flocculation of the pectin with a negative charge, especially when the pectin content in raw sea buckthorn juice is high. Thus adding coagulating agent with a positive charge first should be considered. According to the present invention, the sea buckthorn fruit juice drink has advantages of clarity, transparence, brightness, good stability, almost unchanged transmittance after high temperature or freezing processing, simple and practical method, easy operation, low investment in equipment, low operating costs, and realization of producing clear juice using ordinary template equipment.

Description

The production method of honeybee sea-buchthorn juice beverage

Technical field

The present invention relates to a kind of sea-buchthorn juice beverage, relate in particular to a kind of production method of honeybee sea-buchthorn juice beverage.

Background technology

Commodity Juice divides two classes, i.e. magma type Juice and clarification type Juice, it two by fruit and vegetable materials through making beating, squeezing, filter make.Juice is " brown stain " easily, must prevent brown stain, and Normal juice and magma type fruit juice keeps necessity of suspension system stability in addition at storage period in production.Therefore from fruit and vegetable juice, isolate the material and the bulky grain insoluble matter that cause brown stain, make clarification type fruit juice and be necessary within the scope of clarification type fruit juice, on market, existing apple clear juice and grape juice, do not see city but clarification type sea buckthorn juice is sea-buckthorn clear juice.

Sand-fixation plant sea-buckthorn is a kind of species of mystery, and in China, they grow in the extremely frigid zones including the Inner Mongol, and fructus hippophae/fruit juice has good physiological effect.Compared with other Normal juice, Hippophae (rhamnoides) original juice has three large features: the one, contain the necessary nutriments of human body such as a large amount of natural organic acids, vitamin, Hippophate flavone, vegetable protein, B carrotene.Hippophae (rhamnoides) original juice also contains the materials such as more insoluble fruit flesh component, macromolecular colloid, protein, Polyphenols.These materials particularly phenols component and protein, the pectin etc. such as gallic acid, caffeic acid, catechin are the principal elements that causes that juice browning, muddiness and precipitation form.So just make sea buckthorn juice that precipitation and brown stain very easily occur, the shelf-life is short, stores very difficultly, affects the outward appearance of product and consumer's appetite, has also seriously limited the application of sea buckthorn juice and the development of industry.Rejecting can cause the main matter that sea buckthorn juice brown stain, muddiness and precipitation form, and produces sea-buckthorn clear juice, and to improve the shelf-life of sea buckthorn juice, convenient storage and application are necessary.

The feature two of Hippophae Rhamnoides L. juice is that acidity wants high more than other fruit juice (pH value approximately 4), and pH value reaches below 2.8.At present, the production of clarification type Juice both at home and abroad all adopts the membrane filtration technique of " ultrafiltration ".Film separates and also cries micro porous filtration, is a kind of separation method of the selection permeability that uses pellicle, can only make solvent and micromolecular solute pass through, and can filter the solid particle of 0.1～10um, produces as clear as crystal clarification type Juice.And current membrane filtration technique extensively adopts PS membrane in producing, perishable under its high acidity condition below PH2.8, although processing film, the ceramic membrane of existing acid and alkali-resistance or pottery occur, because expensive being difficult to accepted.Because Hippophae (rhamnoides) original juice acidity is high, can not adopt the membrane filtration technique of " ultrafiltration " to realize production.Final employing flame filter press of the present invention filters, and produces clarification type sea buckthorn juice.Directly can not produce satisfactory clarification type Juice with flame filter press, the fruit juice (clear juice) that the fruit juice that filters out with flame filter press (clear juice) mass ratio filters out with membrane filtration technique ropy a lot, its leading indicator light transmittance does not reach more than 85% requirement at all.

The production of current China sea-buckthorn clear juice is by the original precipitation method, is put into natural sedimentation in large pond by Hippophae (rhamnoides) original juice, after one month, the grease on top, pond is skimmed, and the fruit juice in the middle of extracting out is exactly clear juice.Owing to depositing under field conditions (factors) for a long time, can there are various biochemical reactions, exist the amount reproduction of microorganism and a large amount of losses of nutritional labeling.The light transmittance of sea buckthorn juice and product quality are all very low, also do not produce at present the precedent of sea-buckthorn clear juice by scientific method.Domestic in other fruit-vegetable clear juices are produced, the current macromolecular compound flocculence that generally adopts " bentonite, gelatin, Ludox " pattern.Show but put into practice, due to sea buckthorn juice complicated component, each components compatibility is peculiar, and suspension and pectin content want high more than other fruit juice, and therefore this pattern is not suitable for production sea-buckthorn clear juice, and product light transmittance is inadequate, and has rear research of chaotic phenomenon.Therefore creating a kind of advanced person, science, practicality, modern production sea-buckthorn clear juice production method, is the common need of society, consumer and production.Key point of the present invention is exactly to process sea buckthorn juice by the comprehensive flocculence of macromolecular compound, produces high-quality sea-buckthorn clear juice product with common, common flame filter press.

Summary of the invention

The object of this invention is to provide a kind of production method of honeybee sea-buchthorn juice beverage, inexpensive, the high-quality of its production.

To achieve these goals, the technical solution adopted in the present invention is: the production method of honeybee sea-buchthorn juice beverage: the reason that " bentonite-gelatin-Ludox " pattern flocculence is not suitable for production sea-buckthorn clear juice roughly has two: one, and the priority of bentonite and gelatin adds " order " to inquire into, bentonite is aobvious elecrtonegativity in fruit juice, gelatin shows electropositive, and ubiquitous pectin majority is elecrtonegativity in sea buckthorn juice, so first add bentonite unfavorable to the coacervation of elecrtonegativity pectin, particularly in the many Hippophae (rhamnoides) original juice occasions of gum level, should consider first to add for this reason and be electropositive flocculating agent.Though the gelatin of being made up of animal skeleton is electropositive, " rabid ox disease " example showing when hidden in recent years time, makes the present invention determine not adopt gelatin, uses same aobvious shell electropositive, that gelling exceedes gelatin instead solidifying sugared, and first it added to Hippophae (rhamnoides) original juice.The solidifying sugar of shell adding is food stage, and the solidifying sugar of food stage shell takes off egg by shrimp and crab shells through soda boiling; In vain, calcium is removed in acidleach ' soda boiling is deacetylated etc., and technique makes; by B. (1; 4) the large molecule of the copolymer group of the amino one 2 deoxidation one B-D-glucose units (GleN) of a 2-and B. (Isosorbide-5-Nitrae) .2. acetamido one 2 one deoxidation one B-D mono-glucose unit (GlcNAc) compositions.On its strand, exist GleNAc-GlcNAc, GlcN? the different glycosidic bonds such as Ac-GIcN, GleN.GlcNA, GlcN-GleN, after dissolving, form the floccule of thickness under acid condition, with positive charge, have very strong Selective adsorption.The phenols components such as gallic acid in fruit juice, caffeic acid, catechin and pectin, protein are the principal elements that causes that juice browning, muddiness and precipitation form.In shitosan clarifying process, these phenolic compounds are oxidized to quinones substance generation condensation reaction and protein bound forms precipitation.Meanwhile, due to shitosan in solution with positive charge, and polyphenols and part pectin is with negative electrical charge, and its electric charge power of different aldehydes matters is different.The phenols components such as gallic acid, caffeic acid, catechin are electrically stronger, can be directly and shitosan effect be flocculated precipitation.This is flocculate the selectively reason of aldehydes matter of shitosan namely.After clarifying by shitosan, the total phenol in sea buckthorn juice has reduced 17.2%. major part juice browning, muddiness and the little aldehydes matter of precipitation impact is retained.So in clarifying process, the nutritional labeling of fruit juice is not produced to large impact.From the analysis to flocculate, wherein contain total phenol of shitosan, protein, pectin and 0.475%.The HPI that clarifies aldehydes matter in 5 front and back fruit juice analyzes and shows to cause that the phenols component such as gallic acid, caffeic acid, catechin and part pectin, the protein of juice browning, muddiness and precipitation formation are really flocculated and have precipitated.

But during by shitosan clarification fructus hippophae Normal juice, residual if any shitosan, also can cause after fruit juice muddyly, affect product quality.We use again silica gel (30%) for this reason, allow and fully react with the silica gel of strong negative electrical charge and positively charged shitosan, continue flocculation sediment, to reach the object that ensures sea-buckthorn clear juice quality.

Pectin in sea buckthorn juice is also the principal element that causes that juice browning, muddiness and precipitation form. because part pectin is with positive charge, although therefore shitosan has certain removing effect to electronegative pectin, remove pectin effect insufficient.For further improving fruit juice product quality, the flocculation component finally adding is selected atlapulgite.Atlapulgite not only plays the effect of filter aid in this technique, and is a kind of clarification adsorbent, at the silica gel roars of laughter same-action of course of reaction neutral zone negative electrical charge, in adsorption precipitation fruit juice with shitosan, the pectin of positive charge.Protein and small flocculation sediment thereof.And can improve the weight of insoluble matter, the speed of quickening clarifying reaction, reduces clarifying reaction time and production cost, enhances productivity, stability and the limpid degree of product.Clarification process is as follows: fructus hippophae Normal juice-survey day shitosan-reaction leaves standstill 4h---and surveying Ludox (30%) consumption described in a mouthful Ludox _ add atlapulgite _ get supernatant _ board and frame machine filtration _ sea-buckthorn clear juice is: shitosan/Ludox=1/ (0.8～1.2), generally get 1/1, atlapulgite consumption is 1～3%, chitosan dosage is 0.05～0.5% (all relatively fruit juice).

Feature of the present invention is the macromolecular compound flocculence that adopts " shitosan, Ludox, atlapulgite " pattern, and application flame filter press is produced clear juice.From electrically analyzing, each flocculant component of the present invention adds order not identical with prior art, and first adding is electropositive shitosan, so be the macromolecular compound flocculence of another kind of pattern.From with equipment, the present invention uses common board and frame machine to filter just can produce sea-buckthorn clear juice, and prior art is could produce clear juice by membrane filtration technique, is the clear juice production of another kind of pattern.It is specially adapted to produce sea-buckthorn clear juice.

Advantage of the present invention: the sea-buckthorn clear juice of 1, producing by the present invention: light transmittance >=85%; As clear as crystal, beautiful; Good stability, after high temperature, freezing processing, light transmittance does not almost change; Sea-buckthorn clear juice quality better, can be widely used in the fields such as beverage, food, fermentation.2, method is simple, feasible, processing ease, and equipment investment is lower, operating cost is low, uses common sheet frame equipment just can realize the production of clear juice.3, clear juice productive rate is higher, reaches 80%, and production cost is lower; Flocculate and clarify agent is cheap to be easy to get.4, solve sea-buckthorn clear juice and be not suitable for a difficult problem of producing with ultrafiltration apparatus.5, sea-buckthorn clear juice is stable, easily stores, and the sea buckthorn juice that has solved long-term puzzlement sea-buckthorn industry stores difficult problem.

Detailed description of the invention

A kind of production method of honeybee sea-buchthorn juice beverage, flocculant one shitosan is dissolved in clear water, fully stirring to make it to dissolve completely and then will dissolve flocculant completely. chitosan aqueous solution joins in proportion and in fructus hippophae Normal juice, advises the fashionable stirring of mouth 5 minutes, leave standstill reaction 4 hours, add in proportion again Ludox (30%) and atlapulgite, after stirring, leave standstill half an hour, take out supernatant from reaction settling tank top, clear liquid filters through diatomite flame filter press, can obtain sea-buckthorn clear juice.
