Abstract

The aim of the present work was to identify the key factors that influence the total anthocyanin content of the aqueous extract of broken riceberry rice (BRR). The eight-run Plackett-Burman design was used to evaluate four factors (BRR particle size, BRR powder/water ratio, extraction temperature, and time). As revealed by the results, the BRR powder/water ratio, extraction temperature, and time had a significant influence on the total anthocyanin content. As a consequence, single-factor tests were conducted using a completely randomised design (CRD), considering BRR powder/water ratio (1:2.5, 1:5, 1:7.5, and 1:10 g/mL), extraction temperature (50, 55, 60, 65, and 70°C), and time (50, 60, 70, 80, and 90 min). Based on the results, the criteria for yield optimisation were a BRR particle size of 60 mesh, BRR powder/water ratio of 1:5, extraction temperature of 60°C, and time of 70 min. With these parameters, the total anthocyanin concentration of the extract was 9.71 mg C3G/g dry material.

应用Plackett-Burman设计筛选和优化破碎米莓米总花青素水提物含量的影响因素

研究了影响碎米莓米水提液中总花青素含量的主要因素。8次Plackett-Burman设计用于评估4个因素(BRR粒度、BRR粉/水比、提取温度和时间)。结果表明，BRR粉水比、提取温度和提取时间对总花青素含量有显著影响。因此，采用完全随机设计(CRD)进行单因素试验，考虑BRR粉/水比(1:2.5、1:5、1:7.5和1:10 g/mL)、提取温度(50、55、60、65和70℃)和时间(50、60、70、80和90 min)。结果表明，在BRR粒度为60目，BRR粉水比为1:5，提取温度为60℃，提取时间为70 min的条件下，提取液中总花青素浓度为9.71 mg C3G/g干料。
