法国叶蛋白的大规模商业生产

Large Commercial Production of Leat Protein Concentrates in France

以奥尔奈厂为例,介绍了法国的叶蛋白生产。该厂有每小时加工鲜草120t的能力,每小时叶蛋白产量约2t,每小时草渣颗粒产量约20t,每年的叶蛋白产量是5000t,草渣颗粒75000t,承担3000hm^2苜蓿的加工。叶蛋白占产品总量的6.25％,为鲜草量的1.67％,得率是原料干物质的8.7％。利用上清液生产白蛋白:加温至80℃,或者用pH=4的酸进行处理,就可得到白蛋白絮凝物。白蛋白是一种植物高级蛋白,在食品和医药上有广泛的用处。

This article introduces the production of LPC (leaf protein concentrates) with Aurny factoy being used as the case study. This factory can process 120 tons of herbs each hour. The hourly output of LPC is approximately 2 tons while the hourly output of herbal residue particles is approximately 20 tons each hour. The annual output of LPC is 5 000 tons and that of herbal residue particles is 7 5000 tons and the factory also undertakes 3 000 hm2 of alfalfa processing. LPC account for 6.25% of the total production at the factory which is 1.67% of the amount of herbs and 8.7% of the dry materials. The factory employs liquid supernatants to produce albumin and is heated up to 80oC or uses pH=4 acid to carry out the processing that allows them to obtain the albumin flocculate. Albumin is a type of superior plant protein that can be broadly applied to foods and medicines.
