Abstract

|
|
To enable off-season peach canning, peaches were halved and processed into solid packs. Following variables were compared in relation to storage stability of solid packs. First as pretreatment-dipping in citric and ascorbic solution after lye peeling; second as pasturization in pouch and hot fill process; third as packaging method-2 ply(PET/PE) and 3 ply(PET/Al/PE) plastic film pouch and metal container; fourth as storage condition -20℃ and 5℃. After 25 weeks storage test, all peaches in different packs were processed into canned peaches just like commercial products, and then quality was
organoleptically evaluated from the viewpoint of processing and storage variable of solid packs. The results are follows;
1. Ascorbic acid dipping in 3 ply pouch and citric acid dipping in 2 ply pouch had better
quality retention effect than any other pretreatments in respective packing.
2. Pasteurization method gave great effect on the color and texture of the solid pack during storage, but not on the quality of the final canned peach.
3. Can and 3 ply packing were better than 2 ply pouch in storage of solid pack and quality of final canned peach.
4. The 5℃ storage gave better quality than 20℃.
