Abstract Cereal processing byproducts including wheat (Triticum aestivum L.) bran, maize (Zea mays L.) bran, and dried distillers grain are currently utilized in animal feed, but they could be utilized in value-added products such as food packaging materials. This study determined the topographical properties and mechanical profiles of films made from arabinoxylan extracts of wheat bran, maize bran, and dried distillers grain with the addition of either glycerol or sorbitol as a plasticizing agent at one of three levels (10, 25, or 50%). The arabinoxylan was extracted from these starting materials via alkaline extraction and purified using α-amylase, protease, and dialysis. Film properties analyzed included surface topography, puncture resistance, tensile strength, and tear resistance. Topographical analysis showed that the films made with wheat bran arabinoxylan were the roughest. The puncture resistances ranged from 0.7 N (dried distillers grain arabinoxylan films plasticized by 10% sorbitol) to 10.1 N (wheat bran arabinoxylan films plasticized by 50% sorbitol). The highest maximum tensile strength was 29.3 MPa for films made with maize bran arabinoxylan plasticized by 10% glycerol. In addition, these arabinoxylan films had tear resistances ranging from 0.3 N (maize bran arabinoxylan films plasticized by 50% glycerol) to 1.9 N (wheat bran arabinoxylan films plasticized by 50% sorbitol). These material profiles provide information about the strengths and weaknesses of 18 novel materials that could serve as food packaging materials in the future.

由麦麸、玉米麸或干酒糟中碱提取的阿拉伯木聚糖制成的薄膜的机械特性和形貌特性

摘要 谷物加工副产品包括小麦 (Triticum aestivum L.) 麸皮、玉米 (Zea mays L.) 麸皮和干酒糟目前用于动物饲料，但它们可用于食品包装材料等增值产品。本研究确定了由小麦麸、玉米麸和干酒糟的阿拉伯木聚糖提取物制成的薄膜的地形特性和机械特性，并添加了三个水平（10、25 或 50 %）。阿拉伯木聚糖是通过碱提取从这些起始材料中提取出来的，并使用 α-淀粉酶、蛋白酶和透析进行纯化。分析的薄膜特性包括表面形貌、抗穿刺性、拉伸强度和抗撕裂性。地形分析表明，用麦麸阿拉伯木聚糖制成的薄膜最粗糙。抗穿刺性范围为 0.7 N（由 10% 山梨糖醇增塑的干燥酒糟阿拉伯木聚糖薄膜）至 10.1 N（由 50% 山梨糖醇增塑的麦麸阿拉伯木聚糖薄膜）。用 10% 甘油增塑的玉米麸阿拉伯木聚糖制成的薄膜的最高最大拉伸强度为 29.3 MPa。此外，这些阿拉伯木聚糖薄膜的抗撕裂性范围为 0.3 N（由 50% 甘油增塑的玉米麸阿拉伯木聚糖薄膜）至 1.9 N（由 50% 山梨糖醇增塑的小麦麸皮阿拉伯木聚糖薄膜）。这些材料概况提供了有关未来可用作食品包装材料的 18 种新型材料的优缺点的信息。7 N（由 10% 山梨糖醇增塑的干燥酒糟阿拉伯木聚糖薄膜）至 10.1 N（由 50% 山梨糖醇增塑的麦麸阿拉伯木聚糖薄膜）。用 10% 甘油增塑的玉米麸阿拉伯木聚糖制成的薄膜的最高最大拉伸强度为 29.3 MPa。此外，这些阿拉伯木聚糖薄膜的抗撕裂性范围为 0.3 N（由 50% 甘油增塑的玉米麸阿拉伯木聚糖薄膜）至 1.9 N（由 50% 山梨糖醇增塑的小麦麸皮阿拉伯木聚糖薄膜）。这些材料概况提供了有关未来可用作食品包装材料的 18 种新型材料的优缺点的信息。7 N（由 10% 山梨糖醇增塑的干燥酒糟阿拉伯木聚糖薄膜）至 10.1 N（由 50% 山梨糖醇增塑的麦麸阿拉伯木聚糖薄膜）。对于用 10% 甘油增塑的玉米麸阿拉伯木聚糖制成的薄膜，最高最大拉伸强度为 29.3 MPa。此外，这些阿拉伯木聚糖薄膜的抗撕裂性范围为 0.3 N（由 50% 甘油增塑的玉米麸阿拉伯木聚糖薄膜）至 1.9 N（由 50% 山梨糖醇增塑的小麦麸皮阿拉伯木聚糖薄膜）。这些材料概况提供了有关未来可用作食品包装材料的 18 种新型材料的优缺点的信息。用 10% 甘油增塑的玉米麸阿拉伯木聚糖制成的薄膜为 3 MPa。此外，这些阿拉伯木聚糖薄膜的抗撕裂性范围为 0.3 N（由 50% 甘油增塑的玉米麸阿拉伯木聚糖薄膜）至 1.9 N（由 50% 山梨糖醇增塑的小麦麸皮阿拉伯木聚糖薄膜）。这些材料概况提供了有关未来可用作食品包装材料的 18 种新型材料的优缺点的信息。用 10% 甘油增塑的玉米麸阿拉伯木聚糖制成的薄膜为 3 MPa。此外，这些阿拉伯木聚糖薄膜的抗撕裂性范围为 0.3 N（由 50% 甘油增塑的玉米麸阿拉伯木聚糖薄膜）至 1.9 N（由 50% 山梨糖醇增塑的小麦麸皮阿拉伯木聚糖薄膜）。这些材料概况提供了有关未来可用作食品包装材料的 18 种新型材料的优缺点的信息。
