Embodiment 1

[0042] The addition ratio of the raw material of a kind of thin instant kelp sheet is: fresh kelp: sodium alginate: sodium carboxymethyl cellulose: soybean protein isolate: starch: glycerol is 1:0.001:0.002:0.01:0.001, the addition of cellulase The amount is 80 μ / g.

[0043] A kind of concrete steps of the production technology of thin instant kelp sheet are:

[0044] 1) Cleaning: first wash the kelp with running water, and the surface of the kelp is required to be free of sediment and stains;

[0045] 2) Color protection, soaking to remove bitterness: soak fresh kelp in a copper sulfate solution with a mass concentration of 20ppm for 20 minutes, perform color protection treatment, wash, soak the washed kelp in water at room temperature for 12 hours to remove bitterness, and then cut into 1 -2mm wide spare.

[0046] 3) Deodorization and softening: Under normal temperature conditions, kelp shreds were soaked in 0.5% acetic acid solution for 20 minutes; after deodoriz...

Embodiment 2

[0056] The raw material addition ratio of a kind of thin instant kelp sheet is: fresh kelp: sodium alginate: sodium carboxymethyl cellulose: soybean protein isolate: starch: glycerol is 1:0.003:0.005:0.03:0.004, the addition amount of cellulase It is 130μ / g. In the specific production process, use 40ppm copper acetate to protect the color, soak in water for 48 hours to remove bitterness, soak the kelp shreds in an acetic acid solution with a mass concentration of 2% for 20 minutes, and soak the kelp treated in step (3) at 50°C 1. In the citric acid buffer solution of pH 5.5, the kelp shreds were treated with cellulase 130 μ / g for 2 hours; the enzymatic hydrolyzed kelp shreds were squeezed until the water content was 70%, and the oil was deoiled by centrifugation at 500 r / min for 2 minutes, and the rest of the steps were carried out in the same way example 1.

Embodiment 3

[0058] The raw material addition ratio of a kind of thin instant kelp sheet is: fresh kelp: sodium alginate: sodium carboxymethyl cellulose: soybean protein isolate: starch: glycerin is 1:0.002:0.004:0.02:0.003, the addition amount of cellulase 100μ / g. In the specific production process, use 30ppm copper acetate to protect the color, soak in water for 36 hours to remove bitterness, soak the kelp shreds in an acetic acid solution with a mass concentration of 1% for 20 minutes, and soak the kelp treated in step (3) at 40°C 1. In the citric acid buffer solution of pH5, process kelp shreds with 100 μ / g of cellulase for 2 h; extrude the enzymatic hydrolyzed kelp shreds until the water content is 60%, centrifuge at 400 r / min to deoil for 5 min, and the rest of the steps are the same as in Example 1 .

Abstract

The invention provides a thin instant kelp slice and a production technology thereof. The thin instant kelp slice comprises the following raw materials: fresh kelp, algin, cellulose, sodium carboxymethylcellulose, isolated soy protein, starch and glycerol. The specific processing steps are as follows: cleaning kelp, protecting color, dipping for debitterizing, cutting into filaments, deodorizing, softening, processing cellulose, extruding, mixing, tabletting for shaping, slicing, clamping and shaping by a metal net, vacuum frying, centrifugally deoiling, and packaging into the thin instant kelp slice product after cooled. The thin instant kelp slice processed by the invention has abundant nutrition and crisp taste, is convenient to eat and easy to be accepted by consumers, improves the additional value of the kelp product, has good market prospect and can create greater benefit space for enterprises. In addition, the invention has low requirement on equipment, easy control, strong operability, and low energy consumption and is suitable for the mass production of the thin instant kelp slice.

Description

technical field [0001] The invention belongs to the field of deep processing of kelp products, and more specifically relates to a thin instant kelp sheet and its production technology. Background technique [0002] Kelp is one of the seaweed plants. It is rich in nutrients and mainly grows naturally, but also artificially cultivated. my country's kelp culture has developed into a large-scale industry, and its output accounts for about 50% of the world's seaweed, ranking first in the world. With the development of modern science and technology, people have gradually discovered that kelp has more functions in health care, such as regulating blood lipids, lowering blood sugar, lowering blood pressure, anticoagulation, anti-tumor, anti-mutation and radiation protection, etc. In terms of food processing , the market potential is huge. At present, there are not many domestic products using kelp as the main raw material, mainly dry kelp and high-salt wet kelp. The added value of...
