Abstract

The invention provides a selenium-enriched blueberry fruit powder product and a preparation technology thereof. The selenium-enriched blueberry fruit powder product is prepared from the following raw materials and components in parts by weight: 30-80 parts of blueberry fruit residue fermentation feed liquid, 10-30 parts of water, 10-15 parts of blueberry pigments, 10-30 parts of maltodextrin and 0.2-1 part of sodium carboxymethyl cellulose, and is prepared through the steps of performing mixing and performing spray drying. Inorganic selenium is transformed into organic selenium through microzymes, so that the content of the organic selenium in fruit powder is increased; the autolysis characteristic of yeast is utilized, so that the fruit powder contains a large quantity of small peptide substances; the stickiness of the blueberry fruit powder is reduced, the content of amino acids in the fruit powder is increased, and the mouth feel of the fruit powder is improved; substances with green and astringent taste are removed, the harm of microorganisms to anthocyanidin is reduced, and the content of blueberry anthocyanidin is furthest guaranteed.

Description

Selenium-rich blueberry powder product and preparation method thereof
Technical field
The present invention relates to a kind of selenium-rich blueberry powder product and preparation technology thereof, belong to food processing technology field.
Background technology
Blue berry has another name called blue berry, belongs to Ericaceae Vaccinium plant, and fruit is blueness, in addition to containing abundant nutrition material, also There is anthocyanin etc. can prevent cerebral neurastheria, cardiac function enhancing, improving eyesight and the unique activity material such as anticancer, the most international Food and agricultural organization is classified as one of big health food of the mankind five.China northeast, East China, Central China, South China start to plant on a large scale at present Planting suitable blue berry kind, Blueberry averagely weighs 0.5~2.5g, and maximum weight 5g, edible rate is 100%, sweet and sour palatability, and tool There is fragrant refreshing pleasant fragrance, for eating good merchantable brand raw.Blue berry contains multiple abundant aminoacid, trace element, anthocyanidin (main component For cyanidin-3-galactoside, paeonidin-3-galactoside, C3G) and anthocyanin with And the polyphenols such as catechuic acid, wherein vaccinium oxycoccus pigment non-oxidizability is very strong, has ophthalmology and cardiovascular and cerebrovascular disease preferably Curative effect, can play the multiple efficacies such as aesthetic health care;Vitamin content is general, but vitamin E and pyridoxol content are relatively high;Flavone Class material accounts for the 0.5% of dry weight, and this kind of material has blood pressure lowering, vessel softening, prevents arteriosclerosis, blood sugar lowering, minimizing cholesterol The effects such as accumulation, and fruit juice has capacity of decomposition for carcinogen nitrosamine;Leaf and fruit have the effect such as convergence, heat clearing away, Being used as medicine can invigorating the stomach and promoting digestion, only diarrhoea.Blue berry can be additionally used in treatment and drenches the diseases such as toxicity urethritis, cystitis, and it contains abundant Copper, ferrum, zinc, manganese, calcium, magnesium elements;Manganese element contributes to treating nephropathy, and the content of manganese element is higher than copper, and this helps In defying age;Zinc contributes to treating chronic nephropathy.
Owing to blue berry is perishable, it is not easy to storage and transport, limit the market sale cycle of blue berry, in order to meet The demand of people, market occurs in that blue berry fruit juice, fruit jam and solid beverage, can existing blue berry product many employings Technology in Pressing, Blue berry seed and blue berry peel are all eliminated, and blue berry rich in anthocyanidin most be exactly peel, the not only waste of blue berry resource, Also it is the loss of nutritional labeling.
The Chinese patent of Publication No. CN101579093 discloses the preparation method of a kind of blueberry activated freeze dried powder, blue berry Fruit is cleaned, pre-freeze, distillation, parsing-desiccation, pulverize, the technique such as packaging, obtain blueberry activated freeze dried powder.Wherein said distillation Drying condition is to carry out at-32~-35 DEG C, does not disclose heat supply temperature and drying time, if not having heat in sublimation process Amount supply, then dry rate can be very slow, can be extremely difficult for industrialized production.The most whole process does not has pollutant and micro- Biological preventing control measure, prepared dry powder has microorganism unavoidably and exceeds standard, and product will be caused to cannot be used for raw-food material.
The Chinese patent of Publication No. CN101518280 discloses a kind of side utilizing vacuum freezing technology drying blueberries Method, cleans blue berry, pulls an oar, and then stir prepared slurry;Slurry charging tray is put into vacuum freezing room be dried.But Owing to blue berry belongs to berry, sugary and abundant pectin substance, easily with dish tight adhesion, this method not only have impact on product Yield, dry run can produce dust and affect the work efficiency of dry corollary equipment simultaneously.
The Chinese patent of Publication No. CN102273598A discloses one and utilizes vacuum lyophilization to produce oral blue berry powder Technique, by Blueberry clean, drain after the most standby;Blueberry after draining is-20~-25 DEG C of pre-freezes, vacuum 10 ~30mTorr, keep constant temperature 2-20h;-20~-25 DEG C, carry out pulverizing and obtain rough blue berry lyophilized powder.It is dried because different Stage institute's calorific requirement is different, and drying efficiency can be poor at a temperature of-20~-25 DEG C for the method, and especially material is more In the case of effect can be worse, be not suitable for industrialized production.
The Chinese patent of Publication No. CN102696993A discloses a kind of blue berry dry powder and Freeze Drying Technique system The method of standby blue berry dry powder, through over cleaning, pulverizing, blue berry puree and maltodextrin solution are mixed in proportion, homogenizing, pre-freeze, The steps such as lyophilization prepare blue berry dry powder semi-finished product.This method can face the problems referred to above equally, and the method can not Obtain pure blue berry powder.
In general, all there is pulverizing and dry, pulverize material and stick to the pan or drying time is long, nutrition in above-mentioned prior art The problems such as physical deterioration is big, and energy consumption is high, product former fruity road difference.
Summary of the invention
At present blue berry is directly dried or is pulverized after lyophilizing, and because of fruit powder viscosity, to there will be the most by force this fruit powder dispersibility the poorest etc. Problem, or by blue berry through extracting, being spray-dried to obtain Blueberry pigment powder, owing to blue berry epidermis contains abundant pigment, cause blue berry The problems such as functional component loss is excessive, it is an object of the invention to solve shortcomings and deficiencies of the prior art, it is provided that Yi Zhongli Preparation method by high, the nutritious blueberry powder of rate.
