Evaluation and comparison of the sealing performance of three major types of jar lids available for home canning
|dc.description.abstract||Home canning allows people to preserve seasonal foods and to prepare products that help meet personal dietary needs. There has been increasing interest among people to use reusable lids. Currently, there is no scientific evidence on the sealing performance and reliability of reusable lids. The objective of this study was to evaluate and compare the sealing performance and retention of food quality of three lid systems (metal, plastic and glass) during storage (24h, 10d, 1 and 3mo). These lids were subjected to four different treatments in closing jars (recommended, unwiped, overfilled and combination) using three different foods (tomatoes, apples and carrots) and a total of 192 of each lid type were used. Our results demonstrated that all three lid types had acceptable sealing performance and vacuum levels with all the treatments. However, for best results we would recommend the traditional two-piece metal lid system for highest confidence in sealing.|
