Abstract

Abstract Pulses are important as alternative sources of protein and carbohydrates for the animal industry and, thus, require accurate evaluation of their nutrient profile during processing. Extrusion is a thermal processing of ingredients to induce physiochemical changes that convert them into more valuable products. The current study evaluated the effects of extrusion on the starch and fibre components of Amarillo peas, Dun peas, chickpeas, faba beans, lentils, and soybean meal (SBM). Pulses were extruded at 18% or 22% moisture and 110, 130, or 150 °C. Extrusion decreased (P < 0.05) the starch content in Amarillo and Dun peas but increased (P < 0.05) the same in faba beans, lentils, and SBM when compared with their whole counterparts. There was no difference in the total dietary fibre content of whole and extruded Amarillo peas, Dun peas, chickpeas, and SBM. Extrusion increased (P < 0.05) the soluble dietary fibre (SDF) content of all pulses and SBM except chickpeas. Extrusion increased (P < 0.05) for all fibre types in faba beans. Results indicate that extrusion increased the starch and SDF content of most pulses but had negative or no effects on other fibre components in all pulses except faba beans.

挤压对加拿大豆类淀粉和纤维组成的影响

豆类是动物工业中重要的蛋白质和碳水化合物的替代来源，因此，在加工过程中需要对其营养成分进行准确的评估。挤压是对原料进行热加工，以诱导其发生物理化学变化，从而将其转化为更有价值的产品。本研究评估了挤压对Amarillo豌豆、Dun豌豆、鹰嘴豆、蚕豆、扁豆和豆粕(SBM)淀粉和纤维成分的影响。脉冲在18%或22%的水分和110、130或150°C下挤压。与全粒豌豆相比，挤压降低了阿马利洛豌豆和敦豌豆的淀粉含量(P < 0.05)，而蚕豆、扁豆和豆粕的淀粉含量均有显著提高(P < 0.05)。全粒豌豆、挤压豌豆、鹰嘴豆和豆粕的总膳食纤维含量无显著差异。除鹰嘴豆外，其他豆类和豆粕的可溶性膳食纤维(SDF)含量均有显著提高(P < 0.05)。蚕豆各纤维类型挤压量均增加(P < 0.05)。结果表明，挤压提高了大多数豆类的淀粉和SDF含量，但对除蚕豆外的其他豆类纤维成分没有影响。

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.
