摘要

摘要人类和动物营养都需要替代蛋白质来源,以支持成分的可持续性和不断增长的世界人口的营养需求。挤压是一种用于加工豆类的技术,据报道可以提高淀粉和蛋白质的消化率,但也有可能将营养物质转化为无营养化合物。本研究试图比较挤压对Amarillo豌豆、Dun豌豆、扁豆、鹰嘴豆和蚕豆以及豆粕(对照)营养成分的影响。每个脉冲在18%或22%的湿度和110、130或150°C下挤出。与全样品相比,挤压增加了鹰嘴豆和扁豆的粗蛋白含量,豆粕中粗蛋白含量降低(P<0.05)。与全豆类相比,膨化阿玛里洛豌豆中半胱氨酸含量增加,豆粕中半胱氨酸含量降低(P<0.05)。结果表明,膨化对豆类的蛋白质和氨基酸含量有积极影响,但不同豆类的具体变化不同。

The effects of extrusion on nutrient content of Canadian pulses with a focus on protein and amino acids
Abstract Alternative sources of protein will be required in both human and animal nutrition to support ingredient sustainability and nutrient demands of a growing world population. Extrusion is one technique utilized to process pulses and is reported to increase starch and protein digestibility but also has the potential to transform nutrients into non-nutritious compounds. This study sought to compare the effects of extrusion on nutrient composition in Amarillo peas, Dun peas, lentils, chickpeas, and faba beans, with soybean meal (control). Each pulse was extruded at 18% or 22% moisture and 110, 130, or 150 °C. Compared to whole samples, extrusion increased crude protein content of Amarillo and Dun peas, and lentils, and it decreased in soybean meal (P < 0.05). Compared with whole samples, extrusion increased methionine content in chickpeas and lentils (P < 0.05), with no effect in Amarillo or Dun peas, faba beans, and soybean meal. Cysteine content increased in extruded Amarillo peas compared with whole pulses, and decreased in soybean meal (P < 0.05). Results suggest that extrusion can positively affect protein and amino acid content of pulses, however, specific changes differ by pulse/legume type.

期刊介绍: Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
