Comparison Studies between Conventional Hot Water and Cellulase Extraction for Safflower Dyestuff
초록
Natural red and yellow dyestuff was extracted from safflower (Carthamus tinctorius Linnaeus) by a new process of cellulase extraction compared with the conventional hot water extraction. Dyestuffs were extracted from safflower easily and repeatedly by means of cellulose as safflower cell wall destroyer. It means that new dyestuff extraction by cellulase improves not only yields of dyestuff from safflower successfully but also the rate of repetition of extraction. From the above experiments, the conclusions of this study were summarized as follows. 1. The optimum conditions of dyestuff extraction from safflower by general extraction method were that the solvent was the water of pH 6.0 on yellow dyestuff and 3%
