铁核桃深加工中试生产工艺实践

Pilot-scale production practice of deep processing of Juglans sigillata

铁核桃具有较高的营养和商业价值,然而目前缺少对其深加工的生产工艺。以铁核桃为试验材料,结合我院已建立的铁核桃粉碎脱壳、压榨制油及速溶蛋白粉制备的中试生产线进行工艺实践。结果表明,铁核桃出仁率达95%以上,压榨出油率达85%以上,脱脂粕粉中残油降至1%以下,制备的铁核桃速溶蛋白粉的蛋白质含量达82%。生产过程中的副产物可直接应用于其他相关产品的研发,提高了铁核桃资源的综合利用水平。

Juglans sigillata has high nutritional and commercial value, but there is a lack of production technology for its deep processing.The J. sigillata was processed using the pilot-scale production line of crushing and dehulling, pressing to prepare oil, and instant protein powder preparation established in our institute. The pilot-scale production practice showed that the yields of J. sigillata kernel and pressed oil were above 95% and 85%, respectively, the oil in the defatted meal powder was reduced to less than 1%, and the protein content of the instant protein powder was up to 82%. The by-products in the production process could be directly applied to the research and development of other related products, which greatly improved the comprehensive utilization level of J. sigillata resources.
