Influence of different packaging on the storage of milk candy in tablets

Abstract

The objective of this study was to evaluate the influence of different packaging on the storage of milk candy in tablets by means of moisture, ash, lipid, protein, colour and texture profile analysis. The were used: Expanded polystyrene wrapped with polyvinyl chloride film (PVC), polypropylene (PP) and low-density polyethylene (PEBD) bags. The experiment was conducted in a completely randomised design, and the evaluations were carried out at 0, 45, 90, 135 and 180 days. All treatments presented darkening of the milk candy; however, those candies packaged in PVC presented a light and yellow colour (L = 39.84, b* = 20.06), while those in PEBD presented a dark colour (L = 36.75). According to the conditions studied, PVC packaging is not recommended for the storage of milk candy in tablets due to the intense changes in the physical-chemical characteristics, texture and colour. In contrast, PVC, PP and PEBD packages are efficient materials for maintaining the initial properties of this type of candy.
