Study of Drying Method Types on the Physicochemical Characteristics of Purple-Fleshed Sweet Potato Extract Powder
The purpose of this study was to obtain the best anthocyanin pigment extract powder from 3 types of drying process, vacuum drying, spray drying, and freeze-drying. The duration and temperature for each type of drying process are 15 h with temperature of 40 oC, 2 h with temperature of 120 oC (inlet) and 60 oC (outlet), 24 h with temperature of -50 o</su...
متن کاملIsolation of a regulatory gene of anthocyanin biosynthesis in tuberous roots of purple-fleshed sweet potato.
Many transcriptional factors harboring the R2R3-MYB domain, basic helix-loop-helix domain, or WD40 repeats have been identified in various plant species as regulators of flavonoid biosynthesis in flowers, seeds, and fruits. However, the regulatory elements of flavonoid biosynthesis in underground organs have not yet been elucidated. We isolated the novel MYB genes IbMYB1 and IbMYB2s from purple...
متن کاملPressurized liquid extraction and quantification of anthocyanins in purple-fleshed sweet potato genotypes
Analysis of anthocyanins responsible for the purple flesh color is important for breeding programs and development of value-added products. This study aimed to optimize the conditions for anthocyanin extraction from purple-fleshed sweet potatoes (PFSP) using pressurized-liquid extraction (PLE) method and quantify anthocyanins in various genotypes. Freeze-dried powders of PFSP genotypes were ext...
متن کاملOptimization of Polysaccharide Ultrasonic Extraction Conditions Using Purple Sweet Potato Tubers Based on Free Radical Scavenging and Glycosylation Inhibitory Bioactivities
BACKGROUND The purple sweet potato, Ipomoea batatas, belongs to the family Convolvulaceae. It is one of the most widely consumed tubers in Asia and is found in many dishes. Many people with diabetes eat purple sweet potato tubers to help reduce blood glucose in China. OBJECTIVE To predict the ultrasonic conditions for getting the optimal in vitro antioxidant and antiglycated activity of ultra...
متن کاملAn improved method of isolation of high quality total RNA from purple-fleshed sweet potato, Ipomoea batatas (L.) Lam.
To isolate high quality total RNA from plants of purple-fleshed sweet potato (Ipomoea batatas L. Lam) is difficult because these plants contain high levels of carbohydrates and pigment compounds. In this study, we developed a quick and reliable method for total RNA extraction. Using this extraction protocol, which was derived from the traditional CTAB method with modification, we obtained high ...
