水产下脚料的加工已经成为美国渔业界的头等大事。传统的做法是将下脚料蒸煮、分离、浓缩和干燥等综合加工成鱼粉,但是由于环境污染,许多加工厂被迫停产,有时环境问题导致了原来具有市场竞争力的加工厂倒闭。为了克服这个问题,研究将水产下脚料加工成液体肥料,筛选出—个投资少和操作简单的加工工艺,这是十分必要的。在液体肥料中,低 pH 值可以防止微生物的腐蚀。如果肥料中的蛋白质未被降解,那么肥料在
The processing of fish waste has become a top priority for the U.S. fisheries community. The traditional approach is to process the waste by cooking, separating, concentrating and drying into fishmeal. However, due to environmental pollution, many processing plants are forced to stop production. Sometimes environmental problems lead to the collapse of the original market-competitive processing plant. In order to overcome this problem, it is very necessary to study the processing of the aquatic waste into liquid fertilizer and the screening out of a less expensive and simpler processing technique. In liquid fertilizers, low pH prevents microbial corrosion. If the protein in the fertilizer is not degraded, then the fertilizer is there
