The aim of this study was to investigate the antioxidant, mechanical and physical properties of a new film-based polymeric blend of hydrocolloids obtained from the aqueous extraction of chia seeds (source antioxidants) and apple pectin. The individual matrices films were brittle and rigid with poor mechanical properties. The blends formulations contributed to improved mechanical properties regarding workability and resistance. The antioxidant results showed the potential hydrocolloid from chia seeds as natural source of antioxidant in these polymeric films. The formulation 3 (14(hydrocolloid):41(pectin):25(glycerol):20(glutaraldehyde) displayed well thermal, mechanical, morphological and antioxidant properties, suggesting their great potential for food packaging.
本研究旨在探讨一种新型基于薄膜的水溶胶聚合物共混物的抗氧化、机械和物理性能，该共混物由奇亚籽（源抗氧化剂）和苹果果胶的水提物获得。单独的基质膜脆性大、刚性大，机械性能差。共混物配方有助于提高可加工性和抗张强度方面的机械性能。抗氧化结果表明，从奇亚籽中提取的水溶胶具有作为这些聚合物薄膜中天然抗氧化剂的潜力。配方 3（14（水溶胶）：41（果胶）：25（甘油）：20（戊二醛））表现出良好的热学、力学、形态学和抗氧化性能，表明其在食品包装方面具有巨大的潜力。
