Abstract

This study aims at reducing the post-harvest Aspergillus niger decay incidence of date palm through the biological coating process. To determine the most effective process, chitosan extracted from edible cricket (Schistocerca gregaria) combined with Arabic gum, Aloe vera gel or carboxymethyl cellulose was screened in comparison with the chemical fungicide Benomyl®. Similarly to the Benomyl®, coating dates with chitosan combined with Arabic gum significantly reduced the decay incidence (10 %) compared to untreated dates (100 %) and the weight losses were decreased from 6.02 % to 3.36 %. Coating dates with chitosan added to Arabic gum was selected for optimization using the Plackett-Burman and response surface methodologies approach. Acetic acid, gum Arabic and chitosan quantities were found to be the significant factors influencing the efficiency of the coating bioprocess. The optimized coating bioprocess was experimentally confirmed for the stored dates at 4 °C for 30 days and showed a complete elimination of A. niger decay incidence. The enhanced biological coating process based on chitosan added to gum can be proposed as a promising sustainable solution to reduce the abusive uses of chemical fungicides in Deglet Nour dates and to cut down weight losses during storage.

食用蟋蟀壳聚糖生物包衣工艺的开发与优化，以防治阿尔及利亚枣黑曲霉的腐烂和失重。Deglet努尔

本研究旨在通过生物包衣工艺降低枣椰树采后黑曲霉的腐烂率。为了确定最有效的工艺，筛选了食用蟋蟀（Schistocerca gregaria）中提取的壳聚糖与阿拉伯胶、芦荟凝胶或羧甲基纤维素联合使用，并与化学杀菌剂Benomyl®进行了比较。与Benomyl®类似，与未经处理的枣（100 %）相比，壳聚糖联合阿拉伯胶涂层枣的腐烂率显著降低（10 %），体重损失从6.02 %下降到3.36 %。采用Plackett-Burman法和响应面法对阿拉伯胶中添加壳聚糖包衣枣进行了优化。乙酸、阿拉伯胶和壳聚糖的用量是影响包覆生物工艺效率的重要因素。实验结果表明，优化后的包被工艺在4℃条件下保存30 d，完全消除了黑曲霉的腐烂。在树胶中添加壳聚糖的强化生物包衣工艺可以减少化学杀菌剂在甜枣中的滥用，并减少贮藏过程中的重量损失。

期刊介绍： Process Biochemistry is an application-orientated research journal devoted to reporting advances with originality and novelty, in the science and technology of the processes involving bioactive molecules and living organisms. These processes concern the production of useful metabolites or materials, or the removal of toxic compounds using tools and methods of current biology and engineering. Its main areas of interest include novel bioprocesses and enabling technologies (such as nanobiotechnology, tissue engineering, directed evolution, metabolic engineering, systems biology, and synthetic biology) applicable in food (nutraceutical), healthcare (medical, pharmaceutical, cosmetic), energy (biofuels), environmental, and biorefinery industries and their underlying biological and engineering principles.
