含芦笋提取物的羟乙基纤维素海藻酸钠可食性涂膜对草莓果实采后品质的影响

热点

将芦笋提取物装入羟乙基纤维素/海藻酸钠可食性涂层中。

将该可食性涂膜应用于新鲜草莓的室内贮藏。

可食性涂膜对意大利青霉有生长抑制作用。

可食性涂膜可以延长草莓果实的采后寿命。

可食性涂膜能显著保持草莓果实的品质。

摘要

可食性涂膜已被用作功能化合物的掺入介质，以保持水果的采后质量参数。在本研究中，我们探讨了1.5g/100mL羟乙基纤维素涂层（HEC1.5）、1.5g/100 mL海藻酸钠涂层（SA1.5）以及含有芦笋废料提取物的1.0 g/100 mL HEC和0.5 g/100 mL SA（HEC1.0/SA0.5）复合涂层对草莓果实质量的影响。荧光显微镜和扫描电镜图像显示，HEC1.0/SA0.5涂层呈现出连续、光滑、多孔的结构。HEC1.0/SA0.5涂层对意大利青霉也表现出良好的抗真菌活性。此外，HEC1.0/SA0.5涂层显著延迟颜色变化（ΔE），减少重量损失，并保持总酚和黄酮含量。这些结果表明，使用含芦笋废料提取物的HEC和SA基可食用涂料可以有效、安全和环保地保持草莓果实的质量并延长其货架期。

Effects of hydroxyethyl cellulose and sodium alginate edible coating containing asparagus waste extract on postharvest quality of strawberry fruit

Highlights

Asparagus extract was loaded in hydroxyethyl cellulose/sodium alginate edible coating.

The edible coating was applied to fresh strawberry during room storage.

The edible coating displayed growth inhibition against Penicillium italicum.

The edible coating could extend the postharvest life of strawberry fruit.

The edible coating could significantly retain quality of strawberry fruit.

Abstract

Edible coatingshave been used as a medium for the incorporation of functional compounds to maintain postharvest quality parameters of fruits. In this study, we explored the influence of 1.5 g/100 mL hydroxyethyl cellulose coatings (HEC1.5), 1.5 g/100 mL sodium alginate coatings (SA1.5), and the composite coatings of 1.0 g/100 mL HEC and 0.5 g/100 mL SA (HEC1.0/SA0.5) containing asparagus waste extraction on quality of strawberry fruit. The fluorescence microscope and scanning electron microscope images showed that the HEC1.0/SA0.5 coatings displayed a continuous, smooth and porous structure. The HEC1.0/SA0.5 coatings also exhibited favorable anti-fungal activity againstPenicilliumitalicum. Furthermore, the HEC1.0/SA0.5 coatings significantly delayed color change (ΔE), reduced weight loss, and maintained total phenolic and flavonoid contents. These results indicated that the application of HEC and SA based edible coatings containing asparagus waste extract could be an effective, safe and environmentally friendly approach to maintain the quality and extend the shelf life of strawberry fruit.
