Abstract
The invention discloses plum blossom vinegar rich in gentian oligosaccharide and a fermentation preparation method and belongs to the field of food processing. By steam explosion, structures of bamboo shoot slag, apple pomace and tea residue are much looser. Then, by fermenting aspergillus oryzae while adding cellulose and beta-glucosidase, sweet mash rich in gentian oligosaccharide is obtained. The sweet mash rich in gentian oligosaccharide undergoes colloid mill to obtain plum blossom puree with fine quality. The plum blossom puree and sweet mash are uniformly stirred, and finally saccharomycetes and acetic acid bacteria are added to carry out fermentation so as to obtain original vinegar. According to the invention, residual nutritional value of plum blossom is greatly utilized, and the product also has strong health-care functions. Meanwhile, fruit and vegetable residues and tea residue are reasonably utilized. Thus, cost is reduced to some extent, and economic benefit is boosted.
Description
Technical field
The present invention relates to food processing field, be specifically related to a kind of Flos Mume vinegar rich in gentian oligose and fermentation preparation
Method.
Background technology
Fructus Mali pumilae is the fruit of rosaceous plant, and fruit is spherical, and taste is sweet, and mouthfeel is sharp and clear.Fructus Mali pumilae is kind of a food low in calories, Fructus Mali pumilae
Middle nutrition composition solubility is big, is easily absorbed by the body, is conducive to dissolving element sulphur, makes skin lubrication tender;Bamboo sprout, are that China passes
System delicacies, taste perfume (or spice) matter is crisp, vegetable protein in bamboo sprout, electrolytes and minerals content the highest, contribute to enhancing body
Immunologic function, improves disease resistance ability;Flos Mume has important ornamental value and medical value, and Flos Mume can be used as medicine, and can invigorate blood circulation
Removing toxic substances, profit lung reduces phlegm.
Gentian oligose is a class by glucose with β-1, and the new type functional oligosaccharide that 6 glycosidic bonds combine, including Radix Gentianae
Disaccharide, a small amount of trisaccharide and tetrose.As functional food ingredient, gentian oligose is except having dental caries low in calories, low, whole intestinal
Outside etc. physiological function, compared with other functional oligoses, it can also advantageously promote bacillus bifidus and lactic acid bacteria in human small intestine
Breeding, and heat-resisting, acidproof, can be applicable to some other oligosaccharide and be not suitable in the health food used.But Radix Gentianae is oligomeric
Sugar use cost is high, and current Enzymatic becomes the method reducing cost most effectively, and the glucose that can use high concentration is former
Material, turns glucosides and condensation, the more separated gentian oligose finished product being refining to obtain different size through β glucosidase.
The vinegar product of garden stuff processing is more in the market, and such as Chinese Patent Application No. 201510200178.5 is " a kind of
Apple vinegar beverage ", number of patent application 201310503902.2 " processing method of a kind of asparagus flavored cake ", but there is raw material list
One, and purpose is to improve the local flavor of food not increase the health care of vinegar.Therefore, the present invention from the direction of health food,
Utilizing the waste residue in food production, produce a kind of Flos Mume vinegar rich in gentian oligose, this vinegar not only unique flavor is tasty and refreshing, and
Beneficially people's is healthy.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, the present invention with bamboo sprout slag, pomace, tea grounds, Flos Mume as raw material, Jing Guofa
Ferment prepares a kind of Flos Mume vinegar rich in gentian oligose, and the Flos Mume vinegar using the method to prepare is nutritious, unique tasty and refreshing, favorably
Healthy in people.
A kind of Flos Mume vinegar rich in gentian oligose, this vinegar is by bamboo sprout slag, tea grounds, pomace, Flos Mume fermentation gained.

(5) in the swort of step (4), acetic acid mycopowder is inoculated, under the conditions of 30-33 DEG C by the weight 0.45 ‰-0.85 ‰ with swort
Use solid fermentation 58 days;
(6) filtering fermentation liquor, sterilizing step (5) obtained obtains clear liquor, is then diluted, packs, i.e. available richness
Flos Mume vinegar containing gentian oligose.
Preferably, the fermentation preparation of a kind of Flos Mume vinegar rich in gentian oligose, it is characterised in that:
The preparation method of the colour-keeping liquid of step (3) is: add NaCl, citric acid, CaCl in clear water2, ascorbic acid, sodium sulfite,
Its mass percentage concentration is made to be respectively 1.5%NaCl, 0.6% citric acid, 0.4%CaCl2, 0.10% ascorbic acid, 0.5% sulfurous acid
Sodium.
Compared with prior art, the present invention has a following obvious beneficial effect as can be known from the above technical solutions:
(1) soak, by diluted acid, the method that pomace, tea grounds, bamboo sprout slag and steam explosion combine, raw material can be sufficiently destroyed
The crystal region of middle cellulose so that the quality deliquescing of cellulose, molecular structure is less, and more conducively absorption of human body utilizes, the most sharp
Decomposed by enzyme in cellulose, promote fermentation, acid solution can not only softening fibre raw material, also can solution major part soluble saccharide;
Steam explosion technology can make the structure of raw material the most fluffy simultaneously so that the process of fermentation is the most thorough, completely.
(2) what cellulase hydrolysis obtained is converted into gentian oligose by glucose by β glucosidase, high concentration
Glucose simultaneously facilitates the activity of β glucosidase and cellulase, and therefore cellulase and β glucosidase play mutually association
The effect adjusted.
(3) the flavor precursor matter in fruit and vegerable, tea can be decomposed into and have strong natural flavour mountaineous perfume (or spice) by β glucosidase
Gas material, improves the local flavor of product.
(4) reasonably utilize fruit and vegerable slag, tea grounds, saved cost to a certain extent, and reduced various types of materials
Waste, improves economic benefit, protects environment the most to a certain extent.
(5) raw material adds Flos Mume so that product contains delicate fragrance and the unique oral sensations of Flos Mume.
