Abstract
The invention relates to a preparation method of stachyose and belongs to the field of food additives and a preparation method thereof. The preparation method of stachyose comprises the following steps: adding water and soaking a dry stachys sieboldii product for 1 hour; then, after deactivating enzyme at 100 DEG C for 3 minutes, grinding stachys sieboldii; adding water which is 10-15 times of stachys sieboldii in volume; extracting for 1-2 hours at 30-50 DEG C; centrifugally collecting supernate; adding the supernate into newly prepared lime milk; adjusting the pH to 9.0; stirring and preserving heat for 30 minutes at 70 DEG C; filtering; after neutralizing the filtrate by phosphoric acid, centrifugalizing to obtain supernate; then, adding 2% of active carbon powder in volume into the supernate; heating to 80 DEG C and maintaining constant temperature for 40 minutes, filtering and centrifugalizing; and concentrating the supernate; and spraying and drying to obtain powder which is stachyose. According to the method of preparing stachyose from stachys sieboldii provided by the invention, the product yield is 10.86%, the content of total sugar is 98.9%, the content of stachyose is 91.5%, and the method is simple in process, strong in operability and suitable for industrial production and has the characteristics of being high in product quality and high in recovery rate and the like.
Description
Technical field
The present invention relates to a kind of preparation method of stachyose, belong to foodstuff additive and preparation method thereof field.
Background technology
Stachyose is the tetrose be made up of semi-lactosi-semi-lactosi-Glucose-Fructose, belongs to raffinose and belongs to galactosides irreducibility functional oligose.It can significantly promote that bifidus bacillus breeds, and is therefore described as again " super bifidobacterium "; In addition, stachyose can also promote the increase of short chain fatty acid in intestines, and reduce intestinal pH, relax bowel, it also has immunity moderation, hypoglycemic and reducing blood-fat (cholesterol) function concurrently, and can promote that enteron aisle is to the absorption of the trace element such as calcium, magnesium.Because stachyose has good physico-chemical property and physiological function, and confirm through toxicological experiment, it is safe and reliable, can be widely used in the food such as beverage, milk-product, candy, cake, ice-creams, thus can develop the several functions food of suitable different human consumer's needs.
Stachyose is more extensively present in natural phant, especially contains more rich stachyose in betony Rhizome of Bear's-foot Fern.Rhizome of Bear's-foot Fern, has another name called Chinese artichoke, artichoke betony, gestumor etc., and there are this traditional vegetables on the ground such as China Jiangsu, Hebei, Inner Mongol, Shaanxi and Ningxia.This type of plant is starch-containing hardly, and its main component is moisture content 78%, wherein containing about 12% ~ 15% oligose based on stachyose, is the very good material of processing stachyose and goods thereof.
Therefore, study a kind of technique simple, workable, be applicable to suitability for industrialized production and quality product is high, the method preparing stachyose from Rhizome of Bear's-foot Fern that the rate of recovery is high has good prospect.
Summary of the invention
It is simple, workable that the present invention aims to provide a kind of technique, is applicable to suitability for industrialized production and quality product is high, the method preparing stachyose from Rhizome of Bear's-foot Fern that the rate of recovery is high.
The preparation method of stachyose of the present invention, comprises the following steps:
Rhizome of Bear's-foot Fern dry product is soaked 1h, then after going out enzyme 3min at 100 DEG C, by Rhizome of Bear's-foot Fern defibrination, add the water of Rhizome of Bear's-foot Fern weight 10-15 times volume, lixiviate 1-2h at 30-50 DEG C, collected by centrifugation supernatant liquor, adds in brand-new milk of lime by supernatant liquor, adjust pH9.0,70 DEG C stir insulation 30min, filter, filtrate with in phosphoric acid and after, centrifugal supernatant liquor, in the supernatant liquor of gained, add the active carbon powder of volume 2% weight again, after being heated to 80 DEG C of constant temperature 40min, filter, centrifugal, by supernatant concentration, spraying dry obtains powder and stachyose.
Preferably, amount of water of the present invention is Rhizome of Bear's-foot Fern weight 14 times of volumes, and extraction temperature is 40 DEG C, and extraction time is 1h.
Preferred, Rhizome of Bear's-foot Fern dry product preparation method of the present invention, after being cleaned by fresh Rhizome of Bear's-foot Fern, dries 3h in 70-75 DEG C, continues baking about 30h, obtain the Rhizome of Bear's-foot Fern dry product of yellowish brown at then maintaining 50-55 DEG C.
Preparation method of the present invention, in stachyose leaching process, Extracting temperature, time, the impact of solid-to-liquid ratio on total reducing sugar, stachyose yield are larger.The primary and secondary order of each factor on total reducing sugar and the impact of stachyose yield is solid-to-liquid ratio > extraction time > Extracting temperature, under the extraction conditions of optimum of the present invention, total reducing sugar yield can reach 65.48%, and stachyose yield reaches 46.02%.
In method of the present invention, further crude extract is refined, first adopt milk of lime process, because the composition of crude extract contains a large amount of non-principal components, wherein also be mingled with the impurity such as protein, resinous material, colloid substances and pigment in addition to sugars, so need to carry out clarifying treatment before decolouring.Then adopt activated carbon decolorizing process, utilize the absorption property of gac, removing non-ionic type coloring matter, percent of decolourization reaches 83.8%, and after activated carbon decolorizing, extracting solution becomes light yellow from brown color, again through concentrated, spraying dry, finally obtain pulverous stachyose product.
The method preparing stachyose from Rhizome of Bear's-foot Fern of the present invention, product yield is 10.86%, and total sugar content is 98.9%, stachyose content is 91.5%, there is technique simple, workable, be applicable to suitability for industrialized production and quality product is high, rate of recovery high.
