Description
Technical field
The present invention relates to food processing technology field, in particular to the preparation method of a kind of mulberry fruit capsule of nano and by it
The nutrient powder of composition.
Background technique
Anthocyanidin is also known as anthocyanidin, is a kind of natural pigment, belong to flavonoids, be widely present in all peonys,
In the tissue of plants such as purple or the vegetable and fruit, such as mulberry fruit, grape, blueberry, purple sweet potato, black (red) rice, semen sojae atricolor of blue.
Research has shown that anthocyanidin is that mankind nowadays find most effective antioxidant, has anti-aging, anti-mutation, prevention dynamic
Pulse atherosclerosis, protect liver, eyeshield and other effects.Anthocyanidin in clinical medicine report display blueberry, which can promote in retina cell, to be regarded
The regeneration of sclererythrin can prevent laser high myopia and detached retina, and can promote eyesight.Anthocyanidin can be improved in dim light
Under eyesight；It is helpful to watch people of screen etc. attentively for night motorist for a long time for this.Anthocyanidin is potent anti-oxidant
Agent can maintain normal cell linkages, the stabilization of blood vessel, enhancement fine vascular circulation, the flowing for improving capilary and vein, energy
The enzymatic activity for effectively inhibiting destruction ocular cell, to be beneficial to the health of eyes.
Anthocyanidin is 100% to the biological effectiveness of human body, can be detected in blood within 20 minutes after taking.But cyanine
There is also some defects for element, and if anthocyanidin is very sensitive to pH value, temperature, illumination, metal ion, stability is poor.However it is passing
System is extracted, is concentrated, evaporation and concentration common in purifying process, pH value change the degradation for all easily leading to anthocyanidin.In some plants
In, a small amount of acid can make all or part of hydrolysis of anthocyanin being acylated, to a variety of sides for extracting anthocyanidin from grape
Method compares test and proves, the anthocyanin part water being acylated can be made when the HCl in solvent reaches 0.12mol/L
Solution.
In addition, preparing Fructus Mori extract using existing universal preparation method, obtained anthocyanidin content is about the left side 100mg/g
The right side, the anthocyanidin content extracted is low, does not have good eyeshield eyesight-improving health care function function.
In recent years, capsule of nano technology has become a hot spot of food research and application field.It is micro- with nanometer
Capsule technique embeds active constituent, can not only reduce processing, in storage active constituent loss, but also can be effectively
Into the human body by active constituent conveying.The specific targeting of Nano capsule can make function factor change distribution and be concentrated on
Specific target tissue to achieve the purpose that reduce toxicity, improve curative effect, and improves its biology benefit by controlling the release function factor
With rate, while keeping the quality, structure and its sensory appeal of food.
Summary of the invention
For overcome the deficiencies in the prior art or defect, the purpose of the present invention is to provide a kind of mulberry fruit capsule of nano
Preparation method, the anthocyanidin content of the mulberry fruit capsule of nano obtained using the preparation method is high and anthocyanin absorption rate is high.
It is a further object of the present invention to provide the nutrient powders comprising above-mentioned mulberry fruit capsule of nano.
The present invention is achieved the object of the present invention using following technical scheme:
A kind of preparation method of mulberry fruit capsule of nano, comprising the following steps:
It uses percent by volume for the ethanol water of 45-50% raw material mulberry fruit, and is aided with ultrasonic wave extraction, obtain
Extracting solution obtains purifying concentrate through three-level UF membrane, and purifying concentrate instills pH and receives for what the heat treatment in advance of 6.5-6.9 was crossed
In rice carrier solution, vortex oscillation is embedded at being 20-25 DEG C in temperature, obtains encapsulating solution, the encapsulating solution is through being subcooled
Freeze to be spray-dried and mulberry fruit capsule of nano is made.
Wherein, the anthocyanidin content of the mulberry fruit capsule of nano is 200-300mg/g.
Wherein, the nanoparticle partial size of the mulberry fruit capsule of nano is 20-100 nm.
Wherein, the feed liquid mass volume ratio of the raw material mulberry fruit and ethanol water is 1:10-25；The ultrasonic wave extraction
Process conditions are as follows: ultrasonic power 410-450W, ultrasonic frequency 40-50KHz, ultrasonic treatment time 5-
9min。
Wherein, the film of the three-level UF membrane is selected from the combination of ultrafiltration membrane, three kinds of nanofiltration membrane, reverse osmosis membrane films, UF membrane
The concentration concentration for obtaining purifying concentrate is 2000-2500mg/L.
Wherein, the carrier in the nano-carrier solution of the heat treatment in advance be selected from beta lactoglobulin, Whey Protein Concentrate,
One or more of soybean lecithin, low methoxy pectin, gelatin, chitosan, glycolipid；The processing temperature of the heat treatment in advance
