Embodiment 1

[0024] Step A: Laver Extract Extraction

[0025] (1) Soak the selected seaweed in acetic acid solution, remove the seaweed and drain the water, and then steam it at 100°C, steam it away from the water for 8 minutes, take it out for later use, and dry the steamed seaweed until Moisture≤11-13%

[0026] (2) Carry out steam explosion treatment to the pretreated laver under pressure of 1.4MPa for 2.3min;

[0027] (3) Enzyme treatment: Then add low-temperature cellulase to the product obtained in step (2), and enzymolyze it in a water bath at 35°C for 24 hours,

[0028] (4) Add water 11 times (m / V, g / ml) relative to the dry weight of laver after enzymification, and use a tube centrifuge to centrifuge at a speed of 15000r / min to achieve laver digested residue and supernatant liquid separation;

[0029] (5) The laver digested residue after centrifugation is mainly laver fiber, which is bleached with 0.5% hydrogen peroxide that is 15 times (m / V, g / ml) relative to the dry weight of t...

Embodiment 2

[0035] Step A: Laver Extract Extraction

[0036] (1) Soak the selected seaweed in the acetic acid solution, remove the seaweed and drain the water, and then steam it at a temperature of 90°C, steam it away from the water for 7 minutes, take it out for later use, and dry the steamed seaweed until Moisture≤12%

[0037] (2) Carry out steam explosion treatment to the laver after pretreatment under 1.3MPa pressure maintenance pressure 2.3min;

[0038] (3) Enzyme treatment: then add low-temperature cellulase to the product obtained in step (2), and enzymolyze it in a water bath at 25°C for 48 hours,

[0039] (4) Add water 5 times (m / V, g / ml) relative to the dry weight of laver after enzymification, and use a tube centrifuge to centrifuge at a speed of 2000r / min to achieve laver digested residue and supernatant liquid separation;

[0040] (5) The laver digested residue after centrifugation is mainly laver fiber, which is bleached with 0.52% hydrogen peroxide that is 20 times (m / V, g...

Abstract

The invention relates to porphyra extract fibers, which can be used in the fields of medicine, food and biological degradation. The manufacturing method comprises the following steps: extracting a porphyra extract and manufacturing the fibers. By adopting the manufacturing method, the defects that the traditional sea product extract is low in spinning capacity and low in strength can be overcome, and the porphyra extract fibers with good strength and low swelling property can be rapidly prepared by virtue of the process.

Description

technical field [0001] The invention relates to a laver extract fiber, which can be used in medical, food and biodegradable fields. Background technique [0002] my country faces the sea in the east and has a vast sea area, which can vigorously develop seaweed biomass resources. Seaweed processing products are very rich, such as sodium alginate, iodine and mannitol, seaweed dietary fiber, etc. Among them, sodium alginate is famous for its good biodegradability And biocompatibility, it is widely used in textile, medicine, food, chemistry, biology and other fields; iodine is an indispensable trace element for human growth and development; mannitol can be used in food, medical plastics and other industries. The traditional seaweed processing method is outdated, consumes a lot of water and energy, and lacks deep processing technology, which can no longer meet the needs of my country's social development, especially in the context of increasingly scarce oil resources and biomass r...
