Abstract
The invention discloses a preparation method of clam juice pure powder, which comprises the following steps: firstly filtering clam juice, removing impurities, then performing concentration treatment through a reverse osmosis membrane, further performing vacuum concentration treatment, then performing spray-drying and finally getting the clam juice pure powder. In the preparation method, the reverse osmosis concentration is adopted for retaining nutritional ingredients and aromatic ingredients of the clam juice; furthermore, the energy consumption is low, and the separation efficiency is high; the vacuum concentration enables the quality change of the clam juice to be small; and the spray-drying enables the clam juice pure powder to be uniform in texture, good in dissolution performance and long in storage time, and can also be directly used for forming tablets, granules and capsules.
Description
Technical field
The present invention relates to the preparation method of the pure powder of a kind of clam juice.Belong to field of processing of aquatic products.
Background technology
Clam claims clam again, and many kinds such as colored clam, clam, Coelomactra antiquata are arranged.Fujian Province is the main product ground of clam class, in Liaanjiang county, all there is breed coastal counties and cities such as Fuqing, thinkling sound's fork, Zhangpu, sky, permanently happy, Pingtan, and the output height.Clam class processing at present mainly is in the roughing stage, and converted products mainly is freezing or the clam meat dry product.The boiling stage of clam meat raw material processing procedure has a large amount of juice to flow out, juice fails to be utilized well, and be wasted, the protein that contains about 8%-10% in these clam juice, also contain abundant enhancing immunity, important functional material such as anti-ageing, anti-oxidant, will cause the huge wasting of resources as not recycling.
Publication number is the Chinese invention patent " concentrated clam extract " of CN1088752, introduced a kind of variegated clam Normal juice of utilizing, through the refining senior aquatic products flavouring concentrated clam extract that processes of scientific methods, its main component and content are protein 15-20%, ammoniacal nitrogen 0.8-3%, reduced sugar 2-6%, residue is salt and water, the color milky, the fragrant delicate flavour of taste, concentration 60%.Publication number is the Chinese invention patent " concentrated clam extract " of CN 201356043, has introduced a kind of clam juice separator, has cylinder, rotating shaft is installed in the cylinder, be connected with spiral blade in the rotating shaft, an end of cylinder is provided with charging aperture and juice opening, and the other end is provided with discharging opening; The outside of cylinder is connected with the steam pipeline that is communicated with thorax in the cylinder.
Above-mentioned prior art preferably resolves the problem of clam juice waste, and still, there are some defectives in above-mentioned prior art, and as the energy consumption height, clam meal nutritional labeling and fragrance ingredient detract to some extent, and the clam meal quality is inhomogeneous, solubility property difference etc.
Summary of the invention
Technical problem to be solved by this invention provides the preparation method of the pure powder of a kind of clam juice.This method adopts reverse osmosis concentration to make that clam juice nutritional labeling and fragrant ingredient are kept, and energy consumption is low, the separative efficiency height; Vacuum concentrates and makes the variation of clam juice quality little; Spray-drying make the pure opaque of clam juice ground evenly, solubility property is good, the resting period is long, can also direct feed agent, the moulding of granule, capsule.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
The preparation method of the pure powder of a kind of clam juice, this method comprises the steps:
(1) clam juice is filtered, remove impurity;
(2) the clam juice that utilizes reverse osmosis membrane concentration step (1) to obtain;
(3) the clam juice that obtains through vacuum concentration step (2);
(4) the clam juice that step (3) is obtained carries out spray-drying or vacuum freeze drying, obtains the pure powder of clam juice.
Described clam juice is the juice that is flowed out in the boiling stage of clam meat raw material processing procedure, is called the clam meat liquid of precooking again.
Further, in the described step (2), after the reverse osmosis membrane concentration, clam juice is concentrated into 7-8 ° of Bx, in the described step (3), after the vacuum concentration, clam juice is concentrated into 16-17 ° of Bx.
In the above-mentioned steps, the condition of described reverse osmosis membrane concentration is: initiation pressure is 14-15kgf/cm
2, pressure is 28-30kgf/cm in the concentration process
2, material flow is 7-8L/min, operating temperature is 35-38 ℃.
Described reverse osmosis membrane is a kind of in CAM, acetylbutyrylcellulose film, aromatic polyamide membrane, the aromatic polyamides hydrazides film.
In the above-mentioned steps, the condition of described vacuum concentration is: vacuum is 0.85-0.90MPa, and thickening temperature is 50-55 ℃.
In the above-mentioned steps, described spray-dired condition is: inlet temperature is 113-115 ℃, and outlet temperature is 68-70 ℃, and hot blast rate is 1.1-1.5m
3/ min.
At last, this method also comprises the pure powder of dried clam juice is packed immediately, more helps the preservation of the pure powder of clam juice.
Method of the present invention can also be applied to the soup juice drying of products such as shellfish, shrimps, and the pure opaque ground of preparation evenly, solubility property is good, the resting period is long.
The invention has the advantages that:
1, the present invention is used for clam juice with counter-infiltration and concentrates, and make that clam juice nutritional labeling and fragrant ingredient are kept, and energy consumption is low, the separative efficiency height;
2, the present invention adopts vacuum to concentrate and further handles clam juice, reduces clam juice boiling temperature, the evaporation rate height, and evaporating temperature is low, and it is little that clam juice quality is changed;
3, the present invention adopts spray-drying that clam juice is carried out the drying processing, the automaticity height, and energy consumption is low, the production efficiency height.And even by the pure opaque of the clam juice ground that spray-drying is produced, solubility property is good, and the resting period is long, the moulding of directly feed agent, granule, capsule.
