Problems solved by technology

However, the harvest and use period of fresh kelp is only from April to July, which severely limits the production time of manufacturers.
In order to prolong the service life of fresh kelp and bring higher benefits to enterprises, antiseptic preservation of chemical fresh kelp is an urgent problem to be solved, but there is no research report on this aspect so far

Embodiment 1

[0019] Select about 2 tons of kelp at the mature stage in mid-July, put it in a kimchi pool and add 6 tons of water to soak for 1.5 hours, take it out by a crane to control the water, weigh about 2.2 tons, and place it in a 6m 3 In the white sealed storage tank, 2.3 tons of water, 45kg of sodium carbonate, and 40L of 37% industrial formaldehyde are required after calculation. Sodium carbonate and industrial formaldehyde are dissolved in water to make soaking solution. Pour the soaking liquid into the sealing device to immerse the fresh kelp, seal it and store it at room temperature, and take 20kg of samples regularly according to the number of storage days of 15 days, 30 days, 60 days, 3 months, 4 months and 6 months. Steps such as soaking and color fixing do not need to add sodium carbonate, add 20kg of water to directly digest and extract sodium alginate, and measure the viscosity of sodium alginate. See the following table 1 for the viscosity tracking data of sodium alginat...

Embodiment 2

[0024] Select about 12 tons of kelp in the mature stage in mid-July, put it in a kimchi pool and add 35 tons of water to soak for 2 hours, take it out by a crane to control the water and weigh it, about 13 tons, place it at 30m 3 In the white sealed storage tank, about 19 tons of water, 300kg of sodium carbonate, and 350L of 37% industrial formaldehyde are needed after calculation. Sodium carbonate and industrial formaldehyde are dissolved in water to make a fresh-keeping soaking solution. Pour the fresh-keeping soaking liquid into the sealing device to immerse the fresh kelp, and store it at room temperature after sealing. According to the storage days of 15 days, 30 days, 60 days, 3 months, 4 months and 6 months, 20kg of samples are taken regularly. After soaking, color fixation and other steps, there is no need to add sodium carbonate, add 20kg of water to directly digest and extract sodium alginate, and measure the viscosity of sodium alginate. See Table 2 below for the vi...

Abstract

The invention discloses a method for preserving fresh seaweed by using aldin complex, which comprises the following steps of: selecting the seaweed in the mature period, weighing the seaweed and then adding water to soak the seaweed; preparing fresh soak solution; after the seaweed is sampled and soaked, placing the seaweed into a sealed storage device, then pouring the prepared fresh soak solution into the sealed storage device, and preserving the seaweed airtightly at normal temperature; and taking 20kg of seaweed sample periodically, monitoring and measuring the viscosity of sodium alginate in the preserved seaweed and judging the quality of the preserved seaweed. The fresh seaweed for the chemical industry is preserved by a simple method; and the viscosity of the sodium alginate in the preserved fresh seaweed is high and is over 2,000 mPa.s, and the preservation time is long and is over 6 months.

Description

Technical field: [0001] The invention belongs to brown algae chemical anti-corrosion and fresh-keeping technology, and relates to a method for storing chemical fresh kelp with aldehyde-alkali compound fresh-keeping. Background technique: [0002] Alginate is an important branch of seaweed chemical industry. my country's annual output of alginate is about 30,000 tons, ranking first in the world. As an important product of alginate, sodium alginate is widely used in textile printing and dyeing, medical and health, biotechnology, food, wastewater treatment and other industries. In the brown algae chemical industry, the extraction of sodium alginate from kelp generally takes steps such as soaking, cutting, color fixing, digestion, diluting, foaming, floating, calcification, pickling, washing, neutralization, drying, granulation, and crushing. Then get sodium alginate product. [0003] At present, domestic manufacturers mainly use sun-dried kelp as raw material to extract sodiu...
