FOOD-PACKAGING INTERACTION ON THE STABILITY OF CANNED SWEETENED CUPUAÇU ( Theobroma grandiflorum Schum.) PUREE

ABSTRACT Cupuaçu (Theobroma grandiflorum Schum.) is an exotic fruit with a promising economic potential, particularly due to its strong aroma and creamy texture. This study aimed to produce sweetened cupuaçu puree and evaluate the effects of packaging corrosion on its sensory properties and shelf-life in tinplated cans. After 240 days of storage, the commercially sterile product had average sensory analysis scores of 5.89 ± 0.21, 5.39 ± 0.30, 5.45 ± 0.21 and 5.49 ± 0.25, for appearance, aroma, flavor and overall appreciation, respectively. Sensory acceptance scores did not change during storage (p>0.05). Corrosion potential and low tin and iron levels in the product, which are parameters used to evaluate food-packaging interaction, demonstrated the product remained food-safe throughout its shelf-life. Tinplate is a promising packaging material for sweetened cupuaçu puree due to its mechanical and protective properties. Furthermore, tin plating is an economically viable food technology to extend the shelf-life of cupuaçu products and expand its domestic and international markets.

摘要：库普阿苏果（Cupuaçu，学名：Theobroma grandiflorum Schum.）是一种极具经济开发潜力的异域水果，其核心优势在于浓郁的香气与绵密的质地。本研究旨在制备加糖库普阿苏果果泥，并评估镀锡铁罐包装的腐蚀情况对其感官特性与货架期的影响。储存240天后，该商业无菌产品的感官分析评分分别为：外观5.89±0.21、香气5.39±0.30、风味5.45±0.21及综合接受度5.49±0.25。储存期间，其感官接受度无显著变化（p>0.05）。用于评估食品与包装相互作用的参数——腐蚀电位以及产品中低水平的锡、铁含量，表明该产品在整个货架期内均保持食品安全。镀锡铁皮凭借其优良的机械性能与防护性能，是适配加糖库普阿苏果果泥的极具潜力的包装材料。此外，镀锡工艺作为一种经济可行的食品加工技术，可有效延长库普阿苏果产品的货架期，助力其拓展国内外市场。
