Embodiment 1

[0023] Wash the kelp leftovers with tap water; then soak them in tap water for 24 hours, during which the water is changed every 3 hours; the soaked leftovers are chopped with a knife, and the broken kelp is pulverized by a colloid mill. After crushing, the kelp powder and distilled water are mixed at a volume ratio of 1:5, and the suspension is processed by a low-temperature ultra-high pressure continuous flow cell crusher; the working conditions of the crusher: pressure 50 MPa, continuous flow 2.1 liters / hour, crushing temperature 5°C . Add cellulase and β-glucosidase to kelp homogenate at an enzyme concentration of 500 mg / L, add cellulase and β-glucosidase at a mass ratio of 1:1, adjust the pH to 4.5, and stir at a speed of 100 rpm. After stirring for 5 minutes, the stirring speed was adjusted to 50 rpm, and the entire enzyme biocatalytic conversion reaction process was 3 hours, and the temperature was controlled at 45°C. After the enzymatic hydrolyzate was treated at 80°C...

Abstract

The invention discloses a preparation method of a pure natural concentrated type scindapsus aureus nutrient solution. According to the preparation method disclosed by the invention, the pure natural concentrated type scindapsus aureus nutrient solution is prepared by taking a byproduct-kelp leftover materials of a kelp production and processing enterprise as a raw material, establishing a raw material pretreatment method and developing a kelp bio-refinery technology based on coupling of a low-temperature ultrahigh-pressure continuous flow cell disruption technology, a biological enzymolysis technology and a product falling film evaporation technology, so that resource utilization of kelp processing waste is realized, a kelp industrial chain is extended, and the level of a kelp processing technology is increased; a preparation mode of the pure natural concentrated type scindapsus aureus nutrient solution is innovated, and the byproduct of the kelp production and processing enterprise is used as the raw material, so that waste reclamation is realized, the kelp resource utilization efficiency is increased, the environment is protected, the production cost of the nutrient solution is reduced, the practicability is very strong, large-scale production is easy to realize, and the preparation method is a new method which meets industrial requirements and is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of chemical industry. Background technique [0002] Kelp is a large marine brown algae plant that grows in low-temperature seawater, and belongs to seaweed plants. Kelp Phaeophyceae, Kelpaceae. The sporophytes are large, brown, flat and band-shaped, up to 20m long. It grows in the sea with low water temperature. The northern coast of China and the coasts of Zhejiang and Fujian are extensively cultivated, and its output ranks first in the world. Rich in mineral elements such as alginate and iodine, it can be used as industrial raw materials such as iodine, alginate, and mannitol. Its fronds can be used as medicine. Kelp has many biological functions such as lowering blood fat, lowering blood sugar, regulating immunity, anticoagulation, anti-tumor, detoxifying and anti-oxidation, and is one of the most commonly eaten vegetables. Kelp is processed into various vegetable. [0003] Kelp leftovers refer to ...
