Summary
This 2013 comparative study by Durst and Weaver analysed the nutritional composition of fresh and canned peaches to assess how thermal processing and preservation affect nutrient retention. Whilst canning typically reduces heat-sensitive vitamins such as ascorbic acid, the research provides empirical evidence suggesting that canned peaches retain substantial levels of minerals and certain phytochemicals. The findings contribute to understanding the nutritional trade-offs between fresh and processed fruit formats.
Regional applicability
Peaches are not a staple UK crop; findings are most relevant to consumers and retailers evaluating the relative nutritional merit of imported fresh versus canned peaches available in UK food environments. The data may inform public health messaging around processed fruit consumption where fresh alternatives are limited or costly.
Key measures
Vitamin content (particularly ascorbic acid/vitamin C), mineral composition, and phytochemical levels in fresh versus canned peaches
Outcomes reported
The study compared the nutritional composition of fresh peaches with canned peaches to quantify how thermal processing and preservation methods affect retention of vitamins, minerals, and phytochemicals. The research measured levels of heat-sensitive nutrients and stable micronutrients across both product forms.
