Назив: | Shelf-life of a dragee product based on sunflower kernel depending on packaging materials used | Аутори: | Pajin, Biljana Lazić, Vera Jovanović, Olga Gvozdenović, Jasna |
Датум издавања: | 1-јан-2006 | Часопис: | International Journal of Food Science and Technology | Сажетак: | In this study, we investigated the quality and shelf-life of a dragee product obtained by coating a confectionery sunflower kernel with sugar syrup. The product was packed in oriented polypropylene/oriented polypropylene, oriented polypropylene/metallised oriented polypropylene, polyester/polyethylene and kept at room temperature in daylight for 5 months. At the beginning of the experiment, the dragee product was in the category of excellent sensory quality (total score of sensory evaluation is between 18.0 and 20.0) in terms of its colour, smell, taste, mastication and structure. During the storage, these properties changed and the product lost its stability. Peroxide value in the dragee product increased from 0.5 to 9.0 mmol O/kg during the 5 months of storage. The free fatty acid content also increased from 1.3% in fresh dragee product to 2.5% after 5 months of storage. The packaging material metallised polyester/polyethylene, labelled metPET/PE, has the lowest oxygen permeability (8.0 mL m -2 /dan Δp 1 bar) and because of this it had the strongest influence in the prevention of hydrolytic and oxidative changes in the final product. © 2006 Institute of Food Science and Technology Trust Fund. | URI: | https://open.uns.ac.rs/handle/123456789/12394 | ISSN: | 09505423 | DOI: | 10.1111/j.1365-2621.2005.01147.x |
