摘要

以藏红花球茎提取物（SCE）为活性化合物，研究了以藏红花球茎淀粉（SCS）、羧甲基纤维素（CMC）和聚乙烯醇（PVOH）为主要成分的生物活性膜的研制及其功能特性。该膜具有提高的机械强度、优异的水蒸气阻隔性能和显著的抗氧化活性。30°C条件下，30 d内SCS/CMC/ sce包装开心果的过氧化值（PV）由0.48±0.01增加到5.87±0.85 mmol O2 kg - 1，显著低于对照样品(11.46±1.20 mmol O2 kg - 1, P <；0.05)。在前20天，包装样品的茴香胺值（AV）保持稳定（47±0.28 mmol kg - 1），而ldpe包装的开心果则显著增加（0.96±0.05 mmol kg - 1至3.05±0.14 mmol kg - 1）。该薄膜还显示出很强的抗菌性能，在30天后将霉菌和酵母的计数减少到2.15±0.09 log CFU g−1，而对照组样品的计数为3.70±0.05 log CFU g−1。在SCS/CMC/ sce包装的开心果中黄曲霉毒素含量保持在12 μg kg - 1以下，而ldpe包装的开心果中黄曲霉毒素含量超过30 μg kg - 1。这些发现突出了基于scs的生物活性薄膜作为传统包装的实用和可持续替代品的前景，提供了功能优势和安全性改进。未来的研究应该调查它们在不同环境条件下的可扩展性、成本效益和性能。

Bioactive films from saffron corm and corn husk: A transformative solution for antioxidant and antimicrobial pistachio packaging

This study explored the development and functional properties of bioactive films incorporating saffron corm starch (SCS), carboxymethyl cellulose (CMC), and polyvinyl alcohol (PVOH) with saffron corm extract (SCE) as an active compound. The films exhibited improved mechanical strength, superior water vapor barrier properties, and significant antioxidant activity. The peroxide value (PV) of SCS/CMC/SCE-packaged pistachios increased from 0.48 ± 0.01 to 5.87 ± 0.85 mmol O₂ kg⁻¹ over 30 days at 30 °C, remaining significantly lower than that of control samples (11.46 ± 1.20 mmol O₂ kg⁻¹, P < 0.05). The anisidine value (AV) remained stable (47 ± 0.28 mmol kg⁻¹) in packaged samples for the first 20 days, whereas LDPE-packaged pistachios exhibited a significant increase (0.96 ± 0.05 mmol kg⁻¹ to 3.05 ± 0.14 mmol kg⁻¹). The film also demonstrated strong antimicrobial properties, reducing mold and yeast counts to 2.15 ± 0.09 log CFU g⁻¹, compared to 3.70 ± 0.05 log CFU g⁻¹ in control samples after 30 days. Aflatoxin levels in SCS/CMC/SCE-packaged pistachios remained below 12 μg kg⁻¹, while LDPE-packaged samples exceeded 30 μg kg⁻¹. These findings highlight the promise of SCS-based bioactive films as a practical and sustainable alternative to traditional packaging, providing both functional benefits and safety improvements. Future studies should investigate their scalability, cost-effectiveness, and performance in different environmental conditions.

期刊介绍： LWT - Food Science and Technology is an international journal that publishes innovative papers in the fields of food chemistry, biochemistry, microbiology, technology and nutrition. The work described should be innovative either in the approach or in the methods used. The significance of the results either for the science community or for the food industry must also be specified. Contributions written in English are welcomed in the form of review articles, short reviews, research papers, and research notes. Papers featuring animal trials and cell cultures are outside the scope of the journal and will not be considered for publication.
