Abstract

The invention provides a method for softening kelp and belongs to the technical field of marine food product processing. According to the method, dried kelp is rehydrated to be placed into a mixed solution containing 0.01-0.1% of sodium carbonate and 0.01-0.05% of sodium bicarbonate to be soaked, the soaked kelp is taken out to flush away sodium carbonate and sodium bicarbonate, and then the finished softened dried kelp is obtained through drying. The method has the advantages that softening time is short, softening efficiency is high, and the fishy smell removing effect of the kelp is remarkable; the softened kelp is jade green, full of gloss, crisp and tender without viscosity and full of elasticity, the fishy smell is reduced, the hardness of the kelp can be substantially reduced, the softening efficiency of the kelp can be improved, the time for softening the kelp can be shortened, and the method is suitable for processing and treating the kelp on a large scale and further has the advantages that the cost is lowered, edibility of the kelp is improved, and the flavor is adjusted.

Description

A kind of method of softening sea-tangle
Technical field
The present invention relates to marine products processing technical field, relate to a kind of method of softening sea-tangle particularly.
Background technology
Laminaria guiding principle, Laminariaceae.Be the vegetables that a kind of nutritive value is very high, there is certain medical value simultaneously.Containing mineral matter elements such as abundant iodine.Sea-tangle heat content is low, protein content is medium, mineral matter is abundant, research finds, sea-tangle has reducing blood lipid, hypoglycemic, immunity moderation, anticoagulation, antitumor, lead discharging removing toxic substances and the multiple biological function such as anti-oxidant, its potential source biomolecule activity is subject to people and pays much attention to, and is also one of focus of marine drug research.Sea-tangle quality is hard can affect the mouthfeel of sea-tangle when edible, and not easily completely digested in the gastrointestinal tract, causes sea-tangle Middle nutrition active material not easily absorbed by the body, thus reduces sea-tangle active material absorbing in human body.
And how to carry out softening to sea-tangle be key in the preliminary working of kelp product.The bating effect to sea-tangle of different softening method is different.Disclose a kind of method utilizing sodium carbonate to soften sea-tangle in the article " the different softening method of sea-tangle and the impact on iodine thereof " that 6th phase in 2010 " Chinese food and nutrition " periodical is published, its final result determines that optimum soft condition is that the ratio of sea-tangle 1:20 soaks 15min under normal temperature in 0.3% sodium carbonate liquor.With this softening method process sea-tangle, bating effect is poor, and the processing time is long, sea-tangle soften efficiency low and not easily cleaned up after the sodium carbonate process sea-tangle of higher concentration easily occur residual; Sea-tangle fishy smell after softening is large, and product color is poor, have impact on the quality of sea-tangle.
Summary of the invention
Poor for overcoming sea-tangle bating effect in prior art, the processing time is long, and softening efficiency is low, and softening reagent easily remains; Sea-tangle fishy smell after softening is large; the deficiency of product color difference; the invention provides a kind of operation reasonable, operation is reliable, the sea-tangle softening method of easily accomplishing scale production; adopt the method soften after sea-tangle color emerald green, be rich in gloss; tender and crisp not sticky, high resilience, fishy smell reduces, and both can significantly reduce sea-tangle hardness; sea-tangle can be improved again and soften efficiency, shorten sea-tangle and soften required time.
The present invention solves the technical method that its technical problem adopts: a main laminaria softening method, and it is characterized in that, it is through following process steps:
(1) dry product sea-tangle rehydration;
(2) sodium carbonate and sodium acid carbonate mixed solution soak the sea-tangle after rehydration;
(3) sodium carbonate on sea-tangle and sodium acid carbonate mixed solution is cleaned;
(4) dry sea-tangle.
In the method step (1) of softening sea-tangle of the present invention, dry product sea-tangle rehydration is by dry product kelp soaking about 0.5-3 hour in water, no longer increases to sea-tangle weight.And rehydration completely sea-tangle bright color there is full talent for swimming.
Dry product sea-tangle of the present invention refers to the sea-tangle of fresh salvaging, the dried product obtained after natural drying.
In step (1), cutting is carried out to the sea-tangle after rehydration, to increase the contact area of sea-tangle and sodium carbonate and sodium acid carbonate mixed solution.In an embodiment of the present invention, select by rehydration completely sea-tangle be cut into the consistent Shredded kelp of width.
In step (2), in mixed solution, sodium carbonate mass concentration is 0.01%-0.1%, and the molten mass concentration of sodium acid carbonate is 0.01%-0.05%.
Preferably, in step (2), in mixed solution, sodium carbonate mass concentration is 0.06%-0.08%, and sodium acid carbonate mass concentration is 0.03%-0.05%.
More preferably, in step (2), in mixed solution, sodium carbonate mass concentration is 0.07%, and sodium acid carbonate mass concentration is 0.04%.
In the step (2) of the inventive method, the mass volume ratio of the sea-tangle after rehydration and sodium carbonate, sodium acid carbonate mixed solution is 1:30-100.
Preferably, the mass volume ratio of the sea-tangle after rehydration and sodium carbonate, sodium acid carbonate mixed solution is 1:50.
In step (2), soaking conditions is 60-90 DEG C and soaks 1-5min.
Preferably, in step (2), soaking conditions is 75 DEG C and soaks 2.5min.
In the inventive method, the temperature of step (4) dry sea-tangle is 60-85 DEG C.Temperature is too low, then increase sea-tangle drying time and along with the putrid and deteriorated appearance of sea-tangle, temperature is too high, and sea-tangle is at high temperature easily melted, and affects sea-tangle quality.
The invention provides the application of method in tang food processing field of above-mentioned softening sea-tangle.
The method that the present invention softens sea-tangle has following excellent effect, and (1) softening required time is short, and the softening efficiency high time of softening in above method operates only needs 2.5min, substantially reduces sea-tangle and softens the time; (2) the sea-tangle color after softening is emerald green, is rich in gloss; (3) sea-tangle after softening is tender and crisp does not glue, and high resilience is neither too hard, nor too soft, and fishy smell reduces, good mouthfeel.
