Description
Technical field
The present invention relates to a kind of preparation method of Crassostrea rivularis nutrient solution, and the Crassostrea rivularis nutrient solution adopting the method to obtain.
Background technology
Crassostrea rivularis, has another name called large oyster, and be one of large famous and precious marine products of Guangxi Qinzhou four, meat can be eaten raw, also can be processed into dried oyster, oyster sauce.Large oyster oyster meat is high protein, the aquatic products with very high nutrition and health care function of low fat, delicious flavour, and oyster meat protein content is more than 45%, nutritious, delicious flavour, have the title of " marine milk ", also can be used as medicine simultaneously.Large oyster meat is rich in taurine, can promote human brain development.
In west, oyster is called as " milk in sea ", " sea fruit ", and oyster meat was once thought in ancient times " among extra large race your person ", and this has affirmed fully the nutritive value of oyster.Oyster contains rich in protein, amino acid, also contains abundant vitamin as VA, VB
1, VB
2, VB
3, VB
12, VC, VD
2, VH etc., containing inorganic salts and trace element in oyster meat, have important physiological action to human body.Large oyster contains the amino acid that 19 kinds are needed by human, and taurine is the peculiar composition of oyster sauce, and is rich in 20 various trace elements such as zinc, is strong kidney tonic nutrient product and health food that the male sex is desirable
Along with improving constantly of living standard, the change of people's diet structure, pursues the food of nutrition height and health care, has become people people's fashion.Such as Chinese patent CN102697043A, disclose a kind of method extracting amino-acid nutrition liquid from the male whetstone meat that the little oyster of extra large reef is sharpened, sharpen as primary raw material with the little oyster of extra large reef, make through pre-treatment, immersion, homogenate, enzymolysis, centrifugal, allotment, filling, sterilizing, packaging.Large oyster aquatic products are deeply by the welcome of consumers in general, and market prospects are huge.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of Crassostrea rivularis nutrient solution, and the Crassostrea rivularis nutrient solution adopting the method to obtain.
A preparation method for Crassostrea rivularis nutrient solution, comprises the steps:
1) pre-treatment: choose the good Crassostrea rivularis of freshness, with injection seawer washing, is placed in flowing seawater after filtering Crassostrea rivularis, soaks and tell sand;
2) meat is got: insert until closed flesh in shell from oyster shell trailing edge with blade, the blade that swings is cut and made it open shell from its closed flesh; Cut the closed flesh from being attached in another shell pieces again according to this method, oyster meat just entirely departs from oyster shell, cut from the closed flesh top sticked to oyster shell in operation from, oyster meat is temporarily stored in and has added in the frozen water of trash ice;
3) high pressure microjet ultramicro grinding process: isolated Crassostrea rivularis shell is pulverized, pure water is added according to the weight ratio of 1:8-10, with high-speed shearing emulsion machine process 10-20min, rotating speed is 8000-12000r/min, then process in 25 DEG C with high pressure microjet Ultra-Micro Grinding Equipment, processing pressure is 80-120MPa, and number of processes is 2-4 time, obtains paste serous material;
4) soak: oyster meat is taken out from frozen water, is immersed in and soaks 15-20min containing in 1.5-2.0% sodium chloride, 0.2-0.3% polymeric phosphate and 0.15% lemon aqueous acid;
5) homogenate: the oyster meat after soaking is dropped into washes clean in pure water, after clean oyster meat and pure water being pressed the mixing of 1:0.5-1.0 weight ratio, smash homogenate to pieces with bruisher, the rotating speed of homogenate is 10000-12000r/min, and the time is 8-15min;
6) fermenting: by step 5) homogenate that obtains is through ultra high temperature short time sterilization, then adjust pH6.5-8.0, by volume percentage is that ripe lactic acid bacteria liquid spawn is cultivated in 10-15% access, puts into fermentation cylinder for fermentation, fermentation temperature at 35-37 DEG C, fermentation time 8-10h;
7) post processing: by step 3) and step 6) slurries that obtain and zymotic fluid mixing, centrifugal, supernatant ultra high temperature short time sterilization, sterile filling obtains finished product.
Oyster meat of the present invention refers to the software part of Crassostrea rivularis, i.e. the smart ovum part of Crassostrea rivularis.
Soaking the time of telling sand in described pre-treatment step is 18-20 hour.
In described pre-treatment step, the temperature of frozen water maintains 8-12 DEG C, and the temporary time is 10-15min.
The preferred lactobacillus bulgaricus of described lactic acid bacteria, lactobacillus acidophilus, streptococcus thermophilus, streptococcus cremoris, bifidobacterium bifidum, bifidobacterium infantis, bifidobacterium longum.
Described is centrifugal, and rotating speed is 4500-5000r/min, and the time is 8-15 minute, step 2) and step 5) slurries that obtain and zymotic fluid mixing can form supersaturated solution, precipitated and unstable material by centrifugal segregation.
The invention still further relates to the Crassostrea rivularis nutrient solution adopting preparation method of the present invention to obtain, the Crassostrea rivularis nutrient solution that the present invention obtains can also coordinate with the auxiliary material such as sweetener, acid, to obtain better mouthfeel.
The Crassostrea rivularis nutrient solution that the present invention obtains, can supplement calcium, amino acid and trace element comprehensively, and to exploitation children's intelligence, increasing height has remarkable effect, has intelligence development, digesting and appetizing, increases, the effect of develop immunitypty.
Compared to the prior art, the invention has the advantages that:
1, the present invention is by using high pressure microjet superfine communication technique process Crassostrea rivularis shell, high pressure microjet Ultra-Micro Grinding Equipment is utilized to produce extruding force, shearing force, impulsive force, through liquid-liquid, liquid-solid between high-speed impact, high shear, cavitation etc., the molecular structure of material is changed.High pressure microjet Ultra-Micro Grinding Equipment can accomplish nano-dispersed, thinning effect can reach 0.lum even below, pressure is up to 100-200MPa, the calcium powder particle size distribution obtained is even, have simple to operate, pollution-free, can online cleaning-sterilizing, high efficiency can carry out the plurality of advantages such as breaking-wall cell.
2, in prior art, the shell due to oyster is comparatively hard general not as directly edible material, is carrying out usually removing in the process of processing.Preparation Crassostrea rivularis nutrient solution, the Crassostrea rivularis oyster meat that general employing is fresh, does not use shell.The present invention, by the process to Crassostrea rivularis shell, adds the nutritional labelings such as the calcium of Crassostrea rivularis nutrient solution, magnesium, and content improves more than twice than prior art, and is more easy to absorb.
3, the process of prior art to Crassostrea rivularis oyster meat is generally adopt enzymolysis, enzymolysis can only process albumen, and the present invention is processed by lactic acid bacteria, there is the decomposition promoting protein, monose, and promote the absorption of the nutriment such as calcium, magnesium, produce a large amount of benefit materials such as vitamin B complex, intestinal beneficial flora can also be increased, improve human gastrointestinal tract function, recover colony balance in human body intestinal canal, form antibacterial biological barrier, suppress cholesterol absorption, reducing blood lipid, hypotensive activity, immunoregulation effect, strengthens the effect such as body immunity and resistance.
