Embodiment Construction

[0015] Describe in detail the manufacturing process of the IOTA type carrageenan that the embodiment of the present invention provides below, this production process comprises steps:

[0016] 1. Soak the washed and dried echinacea;

[0017] It is advisable to remove impurities such as salt, silt, and shells contained in Eucheuma spinosa, then dry them in the air, and put them into a KOH alkaline pool with a concentration of 16% for soaking at room temperature for 2 days. When soaking in alkali, the lye needs to cover the algae.

[0018] 2. Wash and filter the Eucheuma spinosa after alkali soaking;

[0019] After soaking Eucheuma spinosa for two days, take it out, put it on the alkali pool to drain the lye, then put it into the washing pool for immersion, and drain it until the washing liquid is neutral (PH7-8).

[0020] 3. Heat and boil the Eucheuma spinach after drying to make the glue dissolve;

[0021] Put the drained Eucheuma spinosa algae into 20-25 times of deionized ...

Abstract

The embodiment of the invention relates to a food additive, and provides a process for manufacturing IOTA carrageenan which is manufactured by using Eucheuma spinosum as a raw material. The process comprises the following steps of: immersing the Eucheuma spinosum with alkali after the Eucheuma spinosum is washed and dried; cleaning and draining the Eucheuma spinosum which is subject to alkali immersion; heating, well cooking and pulping the drained Eucheuma spinosum to dissolve out coarse glue; filter-pressing and cooling the coarse glue to form gel; freezing the gel; unfreezing the frozen gel, and dehydrating the unfrozen gel with a centrifuge; and drying the dehydrated gel to produce the IOTA carrageenan, thereby reducing the manufacturing cost.

Description

technical field [0001] The invention relates to food additives, in particular to a manufacturing process of IOTA type carrageenan. Background technique [0002] Among the nine known carrageenans, there are only two that can form gels and have wide economic value: kappa type and iota type carrageenan. Generally speaking, the hydrogel formed by IOTA-type carrageenan has high strength, brittle hardness and high bleeding property. The current methods of producing these two carrageenans are to use organic solvent (alcohol) dehydration method and press dehydration method. The inventors found that the cost of producing IOTA type carrageenan by these two methods is relatively high. Contents of the invention [0003] The embodiment of the present invention provides a manufacturing process of IOTA type carrageenan, which can reduce the production cost. [0004] The manufacturing process of a kind of IOTA type carrageenan provided by the embodiment of the present invention is reali...
