Technical field

The present invention relates to a kind of preparation method of Radix Astragali preserved fruit, particularly utilize the Radix Astragali to make the method with enhanced machine body immunity function preserved fruit, belong to health food processing technique field.

Background technology

The history of medicinal existing more than 2000 year so far of the Radix Astragali, have enhanced machine body immunity function, protect the liver, diuresis, anti-ageing, resisting stress, step-down and antibacterial action more widely.The Radix Astragali, based on qi-restoratives, is usually used in that with the passing of time body declines, speech is low, small and weak pulse person.Some people is easy to catch cold once meeting Changes in weather, and the traditional Chinese medical science is called " table is not solid ", and admittedly can show with the Radix Astragali, the informal dress Radix Astragali can avoid regular flu.The Radix Astragali can not only coronary artery dilator, improves myocardial blood supply, improves immunologic function, and can delaying cell aging.

Astragalus root is cylinder bar shaped, surperficial light brown yellow or filbert, has vertical wrinkle or longitudinal furrow and horizontal hole skin, the spot that visible part surface comes off, and often coarse have reticulate pattern.Matter is tough and tensile, not frangibility, cross-section fiber shape, and aobvious mealiness, skin zone's yellow-white, more loose, most radial bending crack, xylem is faint yellow, has radial texture and longitudinal crack like radial striations.Taste is slightly sweet chew have beany flavor, cell membrane principal structural component is cellulose, lignin, hemicellulose.

The Radix Astragali belongs to legume, and be the root of Radix Astragali drying, slightly warm in nature, taste is sweet.Return lung, the spleen channel.Tonifying Qi and lifting yang, strengthening exterior and reducing sweat, promoting pus discharge and tissue regeneration, inducing diuresis for removing edema.Effect of useful gas qi-restoratives, strong taste, is applicable to deficiency-weakness of spleen-QI, lassitude hypodynamia, anorexia and loose stool person.Modern study shows, the Radix Astragali, containing multiple antimicrobial component, can strengthen immunologic function, the generation kept off infection.The Ministry of Public Health is defined as the Radix Astragali article that can be used for health food, but not only the Radix Astragali is edible to be needed through blanching, decocts complex operation and bothers but also time-consuming.Radix Astragali mouthfeel edible after processing is also poor, and market does not also have a kind of Radix Astragali edible health food easy to make.

Oligosaccharides is also known as compound sugar, it is the product of a few sugared cyclopolymerization, the saccharide compound of the straight or branched that oligosaccharides is made up of 2 ~ 10 monosaccharide molecule, the sugariness of oligosaccharides is the 20-70% of sucrose, mouthfeel and sucrose similar, oligosaccharides by the stomach acids destroy of human body, also cannot can not decompose by digested ferment.But it can be utilized by the bacterial fermentation in intestines, converts SCFA and lactic acid to.Oligosaccharides it integrate nutrition, health care, dietotherapy, be widely used in the fields such as food, health products, beverage, medicine, feed addictive.It is the new type functional sugar source of alternative sucrose, is Twenty-First Century " future type " functional food of new generation.

Summary of the invention

The invention provides a kind of method utilizing the Radix Astragali to make enhanced machine body immunity function preserved fruit, the method adopts steam explosion technology, cleaning is cut into chunks in the Radix Astragali feeding steam blasting tank of shape, utilize high-temperature high-pressure steam to process the lignocellulosic of the Radix Astragali, high-pressure hot steam enters in Radix Astragali fiber, penetrate into the space of fibrous inside, then produce " explosion " effect by moment pressure release.Radix Astragali fiber surface and cell membrane are subject to destruction in various degree, and are torn by material as fiber fines, produce " puffed rice " sample effect phenomenon, and material area increases, hole increases, and realize separation and the structure change of material.

HTHP makes the softening of the lignin in the Radix Astragali, and the explosion of cellulose crystals and fibre bundle, makes lignin be separated with cellulose, breaks the natural tight structure of hemicellulose and lignin.Vapour is quick-fried makes material major part cellulose, hemicellulose degradation, and cellulosic crystalline texture is destroyed, and lignin regroups and decomposed.The quick-fried material cell membrane that makes of vapour is destroyed, and tears material into fiber fines.Archaeocyte is destructurized, and institute's product institutional framework that obtains is soft, and eucaryotic cell structure is loosened, and fibre crystallinity reduces, and easily digestedly improves nutritive value.

Radix Astragali material is in Steam explosion treatment process, and the beany flavor in the Radix Astragali is added in steam by high temperature and high pressure steam, and along with the beany flavor in high steam pressure release burst of steam is pulled away, the beany flavor in the Radix Astragali is eliminated and makes the taste of product purer.

Adopt Vacuum infusion techniques that the Radix Astragali is put into vacuum impregnation tank, make material inside and outside produce permeable pressure head, impel natural antiseptic agent and sweetener to penetrate in the tissue of Radix Astragali material, thus improve pickling efficiency greatly.Vacuum impregnation temperature is low, speed fast, both saves time, more difficult destruction Radix Astragali Middle nutrition composition, vitamin and various bioactivators.Because whole dipping process is all carry out under air-tight state, reach requirement that is energy-efficient, safety and sanitation.

Beneficial effect of the present invention is, the later half cellulose decomposition of Steam explosion treatment becomes to be immediately used by the body, there is the oligosaccharides of Nutrition and health function, this part cellulose and hemicellulose oligosaccharides are as the carbon source of human body intestinal canal beneficial bacterium Bifidobacterium and lactic acid bacteria and growth factor, the propagation of human body intestinal canal beneficial bacterium can be promoted, stop the field planting of pathogen, immune response stimulating strengthens human immunologic function.The stripping of oligosaccharides adds the sugariness of preserved fruit, reduces the consumption of sugar, reduces the cost making preserved fruit.

Steam blasting pretreatment is considered to a kind of preconditioning technique with application prospect, particularly lignocellulosic material is after the quick-fried process of vapour, break the natural tight structure of material hemicellulose and lignin, major part cellulose, hemicellulose degradation, cellulosic crystalline texture is destroyed, thus realizes Component seperation and the structure change of material.The callus making quality compact becomes loose.Any catalyst is not added in steam blasting pretreatment, and the processing time is short, and active nutritional material damage is few, maintains the original color and luster of the Radix Astragali and local flavor.Steam explosion treatment is a kind of economy, method effectively and reasonably, and Steam explosion treatment latter made Radix Astragali preserved fruit soft taste, is particularly suitable for old man, children and weakness of the spleen and the stomach, that resistance is poor edible for patients.
