Effect of Lamitubes Packaging on the Shelf Life of Honey

摘要

A study was undertaken to assess the effectiveness of plastic laminated collapsible tube as a packaging material for honey. Honey was packed in 100 ml capacity laminated tubes having a structure of linear low density polyethylene/aluminum foil/linear low density polyethylene and were exposed to 27 ± 2℃ and 65 ± 2% RH for a period of 12 months. The filled packages were withdrawn at regular intervals from the climatic chamber and product was analyzed in the laboratory. The physico-chemical parameters like moisture content, TSS, pH, etc., were found to be within the permissible limits. The moisture content ranged between 15.22 and 22.53% and TSS was 75.05 and 77.10°Bx. The pH (4.05-4.47) of honey remained unaffected during the entire period of storage and barrier properties of the laminated tubes showed synergistic interaction which inhibited the microbial growth. The honey samples showed overall higher sensory score and no changes in the packaging material in terms of softening, cracking, bulging or delamination were observed. So, it could be concluded that the barrier properties of the plastic laminated collapsible tube can maintain the keeping quality of honey for 370 days at normal storage conditions.
