Title:
METHOD FOR OBTAINING PURIFIED PRODUCT OF CAROTENOIDS
Document Type and Number:
WIPO Patent Application WO/2017/199830
Kind Code:
A1
Abstract:
The invention provides a method for producing carotenoids under the following conditions. When the amount of alkaline substance used in step (I) for extracting carotenoids is taken to be x mol Eq relative to the solids fraction mass (1 kg) of residue (A) from which the phycocyanin has been extracted and the amount of alkaline substance used in the saponification step (II) is taken to be y mol Eq relative to the solids fraction mass (1 kg) of carotenoid extract (B), (1) x and y satisfy either of the following conditions. 1) 1 ≤ x < 3.0, 0 < y ≤ 6.1 and 2.0 ≤ x + y ≤ 8.0. 2) 2.0 ≤ x < 3.0 and y = 0. (2) By satisfying the condition that the temperature at which the step (I) for extracting carotenoids and saponification step (II) are conducted is 30-50°C.
