Abstract
The present invention is with the softening sea-tangle of natrium citricum, and it cooperates with sodium oxalate, sodium carbonate, to sea-tangle soften, digestion process, can make refining edible, medical, daily kelp extract, overall process is carried out mostly at normal temperatures.
The digestion of sea-tangle has two kinds of methods: 1. natrium citricum-sodium carbonate-citric acid method.2. sodium citrate-sodium oxalate-sodium carbonate.
With natrium citricum preliminary treatment sea-tangle, can save the digestion alkali charge, the digestive juice that makes, viscosity is big, and quality is good.It is a kind of up-and-coming seaweed industrial extracting method.
Description
The invention belongs to the seaweed industry extractive technique.
Sea-tangle is used for extracting products such as iodine, sweet mellow wine, sodium alginate industrial.Produce algin in the industrial production both at home and abroad, mostly digest sea-tangle with soda ash, alkali consumption is big.Tianjin Chinese system of weights iodine station-service normal temperature legal system is got algin new technology (in January, 1985 marine alga chemistry and seaweed industry data compilation) raw material digestion formaldehyde 3%, soda ash 15-20%.Haiyang Chemical Plant, Qingdao extracts sodium alginate (in January, 1985 marine alga chemistry and seaweed industry data compilation) with caustic soda.Foochow aquatic products processing station-service acetic acid is used 10% soda ash after handling again, digests (in January, 1985 marine alga chemistry and seaweed industry data compilation) under 55-60 ℃ of temperature.After steeping sea-tangle with sour calcium water logging, Qingdao Huanghai Sea aquatic products research institute survey report No. 238 (nineteen eighty-two) produces sodium alginate.External with the pretreatment procedure of acid soak as the marine alga glue, but adhesiveness descends.
Sea-tangle is except that having the important use industrial, and it still is that domestic and international people like the edible vegetable with nutritive value eaten, and up to the present, modal eating method is to clean to hot plate to cook to eat, but very difficult burning is mashed, edible back indigestibility.At present both at home and abroad edible kelp food mostly forms through machining, and as sea-tangle silk, powder, sauce, its nutritional labeling mainly is the alginic acid salt, and most of soluble nutrient is dissolved in the wash water in the process.
In order to overcome above-mentioned shortcoming, the present invention adopts a kind of new digestion sea-tangle method, make can be edible the sea-tangle digestive juice, it contains original a large amount of various nutritional labelings in the sea-tangle, is much higher than existing various kelp food as edible its nutritive value.In addition, because sea-tangle has carried out digestion process, the algin that insoluble difficulty is absorbed by human consumption is converted into the sodium alginate sylvite of solubility.Edible this extract can play the nutrition and health care effect to human body, and this is the edible important channel of sea-tangle, and this eating method is not also being seen at present.
Refining extract of the present invention can be made diet food additive, medicinal, commodity, kelp sauce can replace commercially available various kelp foods, also can be refined into dried sea-tangle powder, than the often edible sea-tangle powder nutrition height of states such as the present U.S., Japan, the Soviet Union, it is more being rich in nutrition also to make food additives than some materials that extract such as sodium alginate from sea-tangle.
Main points of the present invention are:
1. with natrium citricum (Na
3C
6H
5O
72H
2O) make pretreating agent, sea-tangle is softened, can economize on alkali number greatly like this, the digestive juice viscosity that makes is big, and quality is good.
2. generally produce with the normal temperature method, power consumption is few in the technical process.
3. do not produce waste water in the production technology of edible extract, waste residue can be done edible or make feed.
4. refining extract can be used in the diet product, medicine and commodity, and the kelp sauce that makes through digestion can replace commercially available kelp product, instant, nutrient inventory height.
5. be used the digestion sea-tangle with natrium citricum and sodium oxalate, sodium carbonate, can produce edible and the measured algin product of viscosity matter, and can economize on alkali number greatly.
Chemical reaction base reason of the present invention is:

Be embodiments of the invention below:
The extracting method of sea-tangle digestive juice and technical process
One, natrium citricum-sodium carbonate-citric acid method:
1. air-dry sea-tangle water flush away silt is cut into silk again, is soaked in water, and washes the immersion sedimentation and removes foul, and supernatant is sterilized after filtration, obtains extract for the first time.
2. will embathe back sea-tangle silk, and add the 4%-6% natrium citricum of raw material weight, and carry out 3-4 hour under normal temperature 20-30 ℃, winter, room temperature was 10 ℃, through 3-4 days, made sea-tangle softening, can crumb with hand, and a large amount of mucus strippings are arranged.
3. the sea-tangle silk thin up after softening, by the nylon wire coarse filtration, centrifugal the getting of filtrate made with extra care extract for the second time.
4. the filter residue after softening the processing carries out digestion under the normal temperature with sodium carbonate, and the consumption of sodium carbonate is the 1%-3% of raw material weight.
5. after digestion is finished, thin up, the citric acid that adds concentration again and be 3%-4% is neutralized to PH7, centrifugal then refined liquid for the third time.
Above-mentioned three refined liquid merge and get promptly that sea-tangle eats, medical extract.
Two, natrium citricum-sodium oxalate-sodium carbonate method.
Sea-tangle wash water, immersion water are used for industrial iodine, the sweet mellow wine carried, and the sea-tangle silk after the immersion adds natrium citricum and sodium oxalate digests, and perhaps adds natrium citricum, sodium oxalate and three kinds of reagent mix of sodium carbonate and digests.Reagent dosage is respectively the 2-4% of raw material weight; 0.5-2%; 0.5-2%.Digestive juice is used for making edible sodium alginate through centrifugal or make extract by existing commercial run.
Mandatory declaration be that its technical process of extracting method of the edible digestive juice of sea-tangle is softened mostly at room temperature, digestion process.Promptly 20-30 ℃ through 2-4 hour, winter, 10 ℃ of room temperatures were through 3-4 days.Carry out for adding fast response, can handle under 30-50 ℃ condition winter, keeps getting final product in 2-3 hour.
Figure of description 1 is a process flow diagram of the present invention, and its symbol description is as follows:
1. raw material is washed the softening cylinders 6. digestion cylinders of pond 2. vegetable-choppers, 3. sea-tangle silk fermentation vats, 4. vibrating-dewatering screens 5. 7. organic bases and is dissolved No. 15. 3 extracts of cylinder 8. soda ash digestion pot 9.10. centrifuge 11. coarse filtration sieve 12. husky filter disinfecting and sterilizing device No. 13. extracts 14. secondary raffinates 16. and soak water and carry iodine, sweet mellow wine 17. waste residues.
