Abstract. The extraction of astaxanthin (ATX) from white leg
shrimp (Litopenaeus vannamei) shells by matrix solid-phase dispersion was
conducted to evaluate the conditions and efficiency of the extraction. The
first experiment was conducted to determine the effect of the ratio of raw
material to dispersion agent on the extraction efficiency of ATX from white leg
shrimp shells. The second experiment investigated the effect of moisture of raw
materials on extraction efficiency. The results showed that white leg shrimp
shells mixed with silica gel at the ratio of silica gel to raw material of 5%
and moisture of raw materials of 30% produce the highest ATX extraction efficiency.
In these conditions, ATX yield was 17.2 |jg g-1 raw material at the given
moisture. After evaporation, the ATX content was 3.4 mg g-1 final extracted
product.
