Improving canning properties of potatoes

土豆是安大略省种植的最大蔬菜作物(15，1，29公顷，OMAFRA 2011年人口普查)，而在Weil‘s Food Processing Ltd.用于罐头的土豆(即小薯)因加工和餐桌库存用途而不合格。目前，土豆的选择主要基于比重；然而，这并不能确保一致的最终产品质量，主要缺陷是松弛(解体/破裂)(Mark Weil，Weil‘s Food Processing Ltd.，Personal Communications)。因此，在有效选择品种方面存在着明确的知识差距。这项拟议的研究将筛选韦尔食品加工有限公司使用的各种安大略省种植的品种，以更好地了解比重、淀粉组成和罐头质量之间的关系。

Potatoes are the largest vegetable crop grown in Ontario (15,1 29 hectares, OMAFRA 2011 census) and those used for canning at Weil's Food Processing Ltd. are graded out (i.e., small potatoes) from processing and table stock use. Presently, potatoes are selected primarily on the basis of specific gravity; however, this does not ensure consistent, final end-product quality, the major defect being sloughing (disintegration/cracking) (Mark Weil, Weil's Food Processing Ltd., personal communication). A definite knowledge gap, therefore, exists regarding the effective selection of cultivars. The proposed study will screen various Ontario-grown cultivars used by Weil's Food Processing Ltd. in order to better understand the relationship among specific gravity, starch composition and canning quality.
