Abstract

This study aimed to develop bio-composite films based on soy protein and Chondrus crispus mucilage enriched with terebinth essential oil (TEO). Films designated as TEO-0, TEO-0.25, TEO-0.5, TEO-0.75, and TEO-1 were prepared, containing 0 %, 0.25 %, 0.5 %, 0.75 %, and 1 % (w/v) TEO, respectively. The physicochemical, barrier, optical, color, mechanical, structural, and crystallinity properties of films were examined. Furthermore, film-forming solutions were used to coat fresh cheese, and their weight loss, pH, and color characteristics were evaluated during 15 days of refrigerated storage. The effect of TEO on thickness, elongation at break (EAB), oxygen permeability, and opacity was found to be significant (p < 0.05). The TEO-0.25 and TEO-0.5 films exhibited the highest elasticity, while TEO-0.25 and TEO-1 films were more effective in reducing oxygen transmission than others. The films displayed relatively high opacity and the TEO-1 film exhibited significantly lower opacity (p < 0.05) compared to the control. TEO addition also significantly decreased the visible region transmittance of the films. Surface SEM images revealed no pores or cracks, though TEO-0.5 and TEO-0.75 films were rougher and more aggregated. FTIR and XRD patterns were similar across all samples. The coating treatments effectively limited changes in weight and pH during cheese storage and were particularly effective in preserving cheese color in the later storage stages.

基于大豆蛋白和富含Pistacia terebinthus 精油的海藻（Chondrus crispus）粘液的生物复合膜：涂层对新鲜奶酪特性的影响

本研究旨在开发基于大豆蛋白和富含布袋莲精油（TEO）的脆骨蕨粘液的生物复合膜。制备的薄膜被命名为 TEO-0、TEO-0.25、TEO-0.5、TEO-0.75 和 TEO-1，分别含有 0 %、0.25 %、0.5 %、0.75 % 和 1 %（w/v）的 TEO。研究了薄膜的物理化学、阻隔性、光学、颜色、机械、结构和结晶度特性。此外，还使用成膜溶液涂覆新鲜奶酪，并对其在冷藏 15 天期间的失重、pH 值和颜色特性进行了评估。结果发现，TEO 对厚度、断裂伸长率（EAB）、透氧率和不透明度的影响显著（p < 0.05）。TEO-0.25 和 TEO-0.5 薄膜的弹性最高，而 TEO-0.25 和 TEO-1 薄膜在降低氧气透过率方面比其他薄膜更有效。薄膜的不透明度相对较高，与对照组相比，TEO-1 薄膜的不透明度明显较低（p < 0.05）。添加 TEO 还能明显降低薄膜在可见光区域的透射率。虽然 TEO-0.5 和 TEO-0.75 薄膜更粗糙、更聚集，但表面 SEM 图像显示没有孔隙或裂缝。所有样品的傅立叶变换红外光谱和 XRD 图谱相似。涂层处理有效地限制了奶酪储存过程中重量和 pH 值的变化，尤其是在后期储存阶段有效地保持了奶酪的颜色。

期刊介绍： Algal Research is an international phycology journal covering all areas of emerging technologies in algae biology, biomass production, cultivation, harvesting, extraction, bioproducts, biorefinery, engineering, and econometrics. Algae is defined to include cyanobacteria, microalgae, and protists and symbionts of interest in biotechnology. The journal publishes original research and reviews for the following scope: algal biology, including but not exclusive to: phylogeny, biodiversity, molecular traits, metabolic regulation, and genetic engineering, algal cultivation, e.g. phototrophic systems, heterotrophic systems, and mixotrophic systems, algal harvesting and extraction systems, biotechnology to convert algal biomass and components into biofuels and bioproducts, e.g., nutraceuticals, pharmaceuticals, animal feed, plastics, etc. algal products and their economic assessment
