Problems solved by technology

[0003] In the existing process, the fermented liquid is put into the tank and then passed through the centrifuge after being filtered by the plate and frame. Some manufacturers will also add a double filter device behind the centrifuge. The collected enzyme liquid needs to be further concentrated due to its low enzyme activity. Due to the unique physical and chemical properties of enzymes, they can only be concentrated under medium and low temperature conditions, and the enzymes will be inactivated under high temperature conditions. However, the traditional vacuum concentration and thin film evaporation have the disadvantages of huge energy consumption and long time consumption.

Embodiment Construction

[0028] specific implementation plan

[0029] now attached figure 1 The present invention will be further described in detail with specific embodiments.

[0030] Concrete embodiment manufacturing steps are as follows:

[0031] A kind of ornithine extraction process, its extraction process step comprises:

[0032] Step 1, microfiltration filtration: put the fermented liquid of ornithine into the primary filtration equipment to obtain the microfiltration dialysate;

[0033] Step 2, decolorization treatment: putting the obtained microfiltration dialysate into an organic decolorization membrane system for decolorization treatment to obtain a decolorization solution;

[0034] Step 3, concentration treatment: adjust the pH of the decolorized solution after the decolorization treatment, and then perform concentration treatment to obtain ornithine concentrated solution;

[0035] Step 4, adjust the pH: adjust the pH of the obtained ornithine concentrate again to remove the soluble p...

Description

technical field [0001] The invention relates to the technical field of membrane treatment, in particular to an ornithine extraction process. Background technique [0002] In organisms, ornithine is mainly involved in the uric acid cycle and plays an important role in the excretion of ammonia nitrogen in the body. In addition to being used as a reagent and injection in medicine, ornithine is usually used together with arginine to prepare foaming drinks for recovery from fatigue. People need it to build and maintain muscle during strength training. It helps reduce muscle loss during aging. In recent years, ornithine has been widely used in food industry and pharmaceutical industry. [0003] In the existing process, the fermented liquid is put into the tank and then passed through the centrifuge after being filtered by the plate and frame. Some manufacturers will also add a double filter device behind the centrifuge. The collected enzyme liquid needs to be further concentrat...
