Abstract

The natural plant-derived pH indicator film which monitors food freshness during storage has gained attention among researchers due to consumer awareness of food quality, freshness, and food safety. This study aims to develop a semolina/agar-based film (S/A) incorporated with anthocyanins from butterfly pea flower extract (BPE) as a freshness indicator for tiger prawns and freshwater prawn during 4 days of storage at 4±1 °C. The semolina/agar-based butterfly pea extract (S/A/BPE) films were developed with different concentrations of BPE (3, 6, and 9%) by casting method. Increasing BPE up to 9% in the S/A film increased the thickness and moisture content, lowering the films’ water permeability. The film also had a smoother surface structure with a darker colour. Different pH solutions (pH 2.0-12.0) also changed the colour of films, depending on the BPE concentrations. The application of S/A/BPE films on tiger prawns and freshwater prawns caused colour changes from dark blue at day 0 (fresh stage) to intense green at day 2 (beginning of spoilage) indicating the spoilage of samples. The pH values of both prawns were gradually increased. However, no major changes were observed in the texture profile analysis. These results indicate that S/A/BPE film has the potential to be used as a pH indicator film to detect the freshness of prawn samples.

通过加入蝶豌豆花花青素开发基于精米淀粉/琼脂的智能薄膜以监测对虾的新鲜度

由于消费者对食品质量、新鲜度和食品安全的关注，在贮藏过程中监测食品新鲜度的天然植物提取 pH 指示膜受到了研究人员的关注。本研究旨在开发一种添加了蝶豌豆花提取物（BPE）花青素的精粉/琼脂基薄膜（S/A），作为虎虾和淡水对虾在 4±1 °C 下储存 4 天的新鲜度指示剂。用不同浓度的 BPE（3%、6% 和 9%）通过浇铸法制备了基于精粉/琼脂的蝶形花提取物（S/A/BPE）薄膜。将 S/A 薄膜中的 BPE 增加到 9% 会增加薄膜的厚度和含水量，降低薄膜的透水性。薄膜的表面结构也更光滑，颜色更深。不同的 pH 溶液（pH 值为 2.0-12.0）也会改变薄膜的颜色，这取决于 BPE 的浓度。在虎虾和淡水虾上使用 S/A/BPE 薄膜会导致颜色变化，从第 0 天（新鲜阶段）的深蓝色变为第 2 天（开始变质）的浓绿色，表明样品已经变质。两种对虾的 pH 值都逐渐升高。不过，在质构分析中没有观察到重大变化。这些结果表明，S/A/BPE 薄膜具有作为 pH 指示膜的潜力，可用于检测对虾样品的新鲜度。
