摘要:

:本研究旨在探明贮藏期间兼用型甘薯品种营养品质的变化规律,从而为其进一步利用(如加工、食用等)提供理论依据。试验选取‘商薯19 号’、‘漯薯11’和‘漯薯16 号’三个兼用型甘薯品种作为研究材料。在贮藏过程中,收集统计性状数据,并采用比色法测定营养品质数据,随后运用统计软件对所获数据进行分析。结果显示,甘薯商品薯率与干物质消耗率之间呈现显著负相关(决定系数为0.99874);水分消耗率在不同年份间存在极显著差异(P<0.01);不同品种在贮藏期间营养品质指标的变化趋势较为复杂;灰分含量与粗蛋白含量之间表现出极显著的正相关性(决定系数达到0.9819),而其余品质指标间未呈现统一的相关性。干物质消耗率可作为衡量甘薯品种耐贮性较为精准的指标;用于淀粉加工,需根据贮藏时间不同选择不同的品种;贮藏中期则适宜鲜食;兼用型甘薯在贮藏期间营养品质的变化情况较为复杂,仍需进一步深入研究。

Abstract:

To investigate nutritional quality changes law of dual-purpose sweet potato varieties during storage and provide theoretical guidance for further utilization (processing, consumption, etc.), this experiment used three varieties 'Shangshu No.19', 'Luoshu No.11' and 'Luoshu No.16' as test materials. Statistical trait data were collected during storage, and nutritional quality data were obtained using colorimetric methods. Statistical software was employed for data analysis. The results showed that a significant negative correlation existed between marketable tuber rate and dry matter consumption rate (coefficient of determination: 0.99874). Moisture consumption rate showed significant annual variations (P<0.01). Trends in nutritional quality indices varied complexly among varieties during storage. Ash content and crude protein content exhibited a highly significant positive correlation (coefficient of determination: 0.9819), while no unified correlations were observed among other quality indices. Dry matter consumption rate serves as a relatively precise indicator for evaluating sweet potato storability. For industrial starch extraction, targeted cultivar selection is required based on specific storage duration requirements. The complex dynamics of nutritional quality in dual-purpose sweet potatoes during storage warrant further investigation.
