中文摘要: 该文以酿酒葡萄皮渣作为原材料,利用微波法辅助提取酿酒葡萄皮渣中的花色苷,以明胶作为凝胶剂,蔗糖作为甜味剂,以质构分析和感官评分作为评价指标,通过单因素试验和正交试验优化酿酒葡萄皮渣软糖的制备工艺。结果显示,最佳制备工艺为酿酒葡萄皮渣提取液与酿酒葡萄皮渣滤液体积比5∶5(总体积100 mL)、明胶添加量15.0 g、蔗糖添加量40 g,此时的酿酒葡萄皮渣软糖不仅具有较优的口感和外观属性,同时含有丰富的营养物质,其中花色苷含量为1.973 mg/g,具有较强的抗氧化能力,当加入1.0 mL酿酒葡萄皮渣软糖花色苷提取液时,酿酒葡萄皮渣软糖的DPPH自由基清除率可以达到64.2%。
Abstract:This study used wine grape pomace as the raw material. Microwave-assisted extraction (MAE) was employed to extract anthocyanins from the pomace. Gelatin served as the gelling agent and sucrose as the sweetener. Texture analysis and sensory scores were used as evaluation indicators. The preparation process of wine grape pomace fondant was optimized through single-factor experiments and orthogonal experiments. The results showed that the optimal preparation process was as follows:volume ratio of microwave extract of wine grape pomace to filtrate of wine grape pomace (total volume 100 mL) of 5∶5,gelatin addition of 15.0 g,and sucrose addition of 40 g. Under these conditions,the wine grape pomace fondant not only possessed excellent taste and appearance attributes but was also rich in nutrients;the anthocyanin content reached 1.973 mg/g,with a strong antioxidant capacity. When 1.0 mL of the prepared anthocyanin extract of wine grape pomace fondant was added,the DPPH free radical scavenging rate reached 64.2%.
