Abstract

The presented study investigated the effects of edible coatings with concentration of 2%, 3% and 4% of starch (w/v) on the weight loss and firmness loss of green asparagus during 4 days of storage at room temperature (26 ± 2 °C, 65–70% RH). According to the results, the coated asparagus exhibited significantly slower deterioration rate than the uncoated control samples. This was indicated by the decrease in weight loss and increase in firmness (P < 0.05). After the storage period, the samples treated with 4% starch formula retained the highest quality. Furthermore, the assessment of asparagus quality throughout the storage period involved the use of the line laser scattering technique. Extracted parameters of laser scattering signal discriminated samples with linear discriminant analysis (LDA), in which the correct recognition rate of the treated groups was 75.26% and the storage time was 70.54%. This study showed the potential of laser scattering as a rapid, non-invasive, and practical optical method for assessing the quality of asparagus during storage.

利用激光散射法评估用木薯淀粉涂层处理的绿芦笋的质量

本研究调查了在室温（26 ± 2 °C，65-70% 相对湿度）下贮藏 4 天期间，淀粉浓度为 2%、3% 和 4%（重量/体积比）的可食用涂层对绿芦笋重量损失和硬度损失的影响。结果表明，涂有淀粉的芦笋比未涂淀粉的对照样品的变质速度要慢得多。这表现在芦笋的重量损失减少，硬度增加（P < 0.05）。贮藏期结束后，用 4% 淀粉配方处理的芦笋质量保持得最好。此外，在整个贮藏期间对芦笋质量的评估还包括使用线激光散射技术。提取的激光散射信号参数可通过线性判别分析（LDA）对样品进行判别，其中处理组的正确识别率为 75.26%，贮藏时间组的正确识别率为 70.54%。这项研究表明，激光散射作为一种快速、无创、实用的光学方法，在评估芦笋贮藏期间的质量方面具有很大的潜力。
