Embodiment 1

[0026] A method for producing Gracilaria agar based on a mathematical model, comprising the following steps:

[0027] Alkali treatment: After the Gracilaria is rinsed, dry it in an oven at 60°C until it reaches constant weight, prepare 1500mL of NaOH solution with a mass fraction of 1% to 8%, add 100g of Gracilaria, and treat it at a constant temperature in a water bath at 50°C to 90°C for 0.5h~ 3.5 hours;

[0028] Washing, acidification and bleaching: add 100mL water to the alkali-treated Gracilaria to rinse the lye, soak in water for 30min, repeat four times, then add 0.65mL concentrated sulfuric acid, 0.96g oxalic acid and 0.192g EDTA-Na 2 Acidify for 0.5h, continue to add 1500mL of water to soak and wash until the pH is neutral, then add 1500mL of sodium hypochlorite solution with an effective chlorine mass fraction of 0.04%, mix evenly, stir and bleach for 0.5h, pour off the bleaching solution, add 1500mL of water to soak and wash until pH is neutral;

Embodiment 2

[0036] The transparency and the sulfate content of the agar produced under the same experimental alkali treatment process conditions are respectively substituted into the above-mentioned model of embodiment 1: (1) when the transparency is 90.1%, the above-mentioned model is substituted, and the relevant alkali treatment process can be obtained: the alkali treatment concentration is 4.7%, the alkali treatment time is 2.3h, the alkali treatment temperature is 73°C, and the alkali consumption of the production unit agar product is 1.77t; (2) when the sulfate radical content is 5.51%, substituting the above model, the relevant alkali treatment process can be obtained as: The alkali treatment concentration is 5.1%, the alkali treatment time is 2.2h, the alkali treatment temperature is 83°C, and the alkali consumption per unit of agar product produced is 1.83t.

[0037] Comparing the alkali consumption of the above two alkali treatment processes, the alkali consumption is the lowest ...

Abstract

The invention relates to a gracilaria agar production method based on a mathematical model. The gracilaria is subjected to alkali treatment; washing, acidifying and bleaching are carried out on the gracilaria subjected to alkali treatment; gel boiling is carried out on the gracilaria after washing, acidifying and bleaching to obtain gracilaria agar; the gel strength, transparency, 3, 6-anhydro content, sulfate radical content and gel yield of gracilaria agar are measured, the alkali consumption is calculated, a linear equation of experimental data is made, and the linear equation is convertedinto a matrix equation to construct a gracilaria agar quality influence factor kinetic model. According to the method, the alkali consumption and quality of the gracilaria agar under different alkalitreatment processes are calculated by establishing the model, and the method has important significance for the alkali treatment process required for producing the multi-index gracilaria agar and reducing the alkali consumption of the gracilaria agar.

Description

technical field [0001] The invention relates to the technical field of seaweed product processing, in particular to a method for producing Gracilaria agar based on a mathematical model. Background technique [0002] Agar is a hydrophilic colloid extracted from the red seaweed, and it is also a widely used natural water-soluble polysaccharide. As a food additive, cell culture medium, a substitute for manufacturing pharmaceutical capsules and synthetic green plastic packaging materials, etc. The raw materials for agar production are mainly red algae such as Geliflower and Gracilaria. Among them, the large economical algae Gracilaria is rich in agar polysaccharides and is the main raw material for agar production at home and abroad. [0003] At present, Gracilaria agar is mainly extracted by alkali method. Alkali treatment is the key process to reduce the sulfate content of agar and improve the gel strength. Improper control of alkali treatment conditions will lead to the los...
