Problems solved by technology

According to the research of the inventor, during the follow-up processing of Haematococcus, some enterprises adopt the low-temperature storage method in cold storage. Although it can ensure the freshness of algae pulp or algae mud, due to the large operation volume and high energy consumption, it increases unnecessary Therefore, from the point of view of actual operation, it is necessary to find an anti-corrosion method with simple and convenient operation, good anti-corrosion effect, and low energy consumption

Embodiment 1

[0020] The quality of the algal pulp is 1000g, and the concentration is 4g / L. First, adjust the pH of the algal pulp to pH=4 with an appropriate amount of citric acid and potassium hydroxide, then add 2g (1000*0.2%) potassium sorbate to it and mix well , After 3 days, no colony was formed, the algal pulp was not putrefied and smelly, and the microscopic observation found that the algal cells were intact and not ruptured.

Embodiment 2

[0022] The mass of the algal pulp is 1000g, and the concentration is 10g / L. First, adjust the pH of the algal pulp to pH=3 with an appropriate amount of hydrochloric acid and potassium hydroxide, then add 4g (1000*0.4%) potassium sorbate to it, mix well, After 3 days, no colony was seen, the algal pulp was not putrefied and smelly, and the algal cells were found to be intact and not ruptured by microscopic examination.

Embodiment 3

[0024] The quality of the algal pulp is 1000g, and the concentration is 7g / L. First, adjust the pH of the algal pulp to pH=4 with an appropriate amount of citric acid and potassium hydroxide, then add 3g (1000*0.3%) potassium sorbate to it and mix well , After 3 days, no colony was formed, the algal pulp was not putrefied and smelly, and the microscopic observation found that the algal cells were intact and not ruptured.

Abstract

The invention discloses a preservative method of haematococcus pluvialis pulp or mashed haematococcus pluvialis. The method specifically comprises the following steps that firstly, the pH value of thehaematococcus pluvialis pulp of which the concentration is 3g / L-10g / L is regulated with an acid and an alkali to be smaller than or equal to 6, then 0.05%-0.5% of a frequently-used preservative is added to the haematococcus pluvialis pulp, uniform mixing is performed, after 3 days, any colonies are not found to be formed, the haematococcus pluvialis pulp is not rotten or generates bad smell, andthrough microscopic examination, haematococcus pluvialis cells are found to be complete without rupture. According to the preservative method disclosed by the invention, the condition that haematococcus pluvialis liquid is rotten or generates bad smell in the process of concentration or before spray drying can be effectively avoided, the condition that the haematococcus pluvialis cells are damagedand ruptured is also avoided, the product quality cannot be influenced, and the preservative method is low in cost and simple in operation flows.

Description

technical field [0001] The invention relates to a preservative method for Haematococcus pluvialis pulp or mud, belonging to the technical field of feed preservative. Background technique [0002] Astaxanthin is an oxidized form of carotene. Astaxanthin has strong free radical scavenging ability and coloring properties, so astaxanthin and its derivatives have been widely used in the fields of medicine, health care products, skin care products and high-end feed additives. [0003] Culturing Haematococcus pluvialis to produce astaxanthin is the main way to produce natural astaxanthin, in which the content of astaxanthin is as high as 2% to 7% of the dry cell weight, which is the most potential new resource for producing astaxanthin. General attention of domestic and foreign academic and business circles. Astaxanthin products derived from Haematococcus pluvialis have successively obtained GMP, FDA and EU new resource certifications. In my country, Haematococcus pluvialis was ...
