Abstract

Dietary fiber is considered a feed ingredient with high nutritional value in the broiler feed industry. Pine chips contain a large amount of dietary fiber and require some modification for use as broiler feed. In this study, pine chips were subjected to steam explosion under different severity factor (Ro) conditions to improve the chemical and physical properties of dietary fiber. The highest water-holding capacity, oil-holding capacity, and swelling capacity were found for Ro 4.0, followed by Ro 4.5 and 3.5. The optimal condition for the steam explosion was determined to be Ro 4.0 (reaction temperature of 210°C, and reaction time of 6.0 min). Under these conditions, the water-holding capacity, oil-holding capacity, and swelling capacity of steam-exploded pine chips were 8.3 g/g, 6.5 g/g, and 5.0 mL/g, respectively. This study may contribute to the application of lignocellulose and related products in the broiler feed industry.

蒸汽爆炸条件对饲料添加剂松片理化性能改善的影响

在肉鸡饲料工业中，膳食纤维被认为是一种具有较高营养价值的饲料原料。松片含有大量的膳食纤维，作为肉鸡饲料需要进行一定的改性。本研究以松片为原料，在不同的Ro条件下进行蒸汽爆破处理，以改善膳食纤维的理化性质。持水能力、持油能力和溶胀能力以Ro 4.0最高，Ro 4.5次之，Ro 3.5次之。确定了蒸汽爆炸的最佳条件为Ro 4.0(反应温度210℃，反应时间6.0 min)。在此条件下，蒸汽爆炸松片的持水容量为8.3 g/g，持油容量为6.5 g/g，膨胀容量为5.0 mL/g。本研究为木质纤维素及其制品在肉鸡饲料工业中的应用提供了理论依据。

期刊介绍： The Journal of the Korean Wood Science and Technology (JKWST) launched in 1973 as an official publication of the Korean Society of Wood Science and Technology has been served as a core of knowledges on wood science and technology. The Journal acts as a medium for the exchange of research in the area of science and technology related to wood, and publishes results on the biology, chemistry, physics and technology of wood and wood-based products. Research results about applied sciences of wood-based materials are also welcome. The Journal is published bimonthly, and printing six issues per year. Supplemental or special issues are published occasionally. The abbreviated and official title of the journal is ''J. Korean Wood Sci. Technol.''. All submitted manuscripts written in Korean or English are peer-reviewed by more than two reviewers. The title, abstract, acknowledgement, references, and captions of figures and tables should be provided in English for all submitted manuscripts.
