以褐藻海带、宽叶海带和海带为原料，进行了一系列中试规模的大型藻类加工批次(每批50-200公斤)，以生产一系列食品级液体和固体馏分。这一信息通报的目的是向打算大规模加工大型藻类的其他人传达在这一期间吸取的一些经验教训，并结合以前的相关观察和考虑。因此，本文的创新之处在于在学术成果和实际技术之间架起一座桥梁。考虑范围包括材料多样性；非生物和生物的影响和变化；以及供应链考虑。观察范围包括铣削和切割；设备要求；以及酸，包括它们对重金属，特别是铅的影响。建议总结了这次试点和以前的工作的要点。这些因素包括：收获季节、水质和靠近加工设施；尽量减少巨藻内的污染物，如石头和贝壳；考虑所有步骤和过程的设备组成和体积，包括最终产品质量；酸的选择及其对所用设备和巨藻中生物积累的金属的影响。
Using brown seaweed kelp species Saccharina latissima and Laminaria digitata as feedstocks, a set of pilot-scale macroalgae processing batches were conducted (50-200 kg per batch) for the production of a range of food-grade liquid and solid fractions. The aim of this communication is to relay a number of lessons learnt during this period in combination with previous relevant observations and considerations for others who are intending to process macroalgae at scale. The novelty of this paper is thus to form a bridge between academic findings and practical know-how. Considerations covers material diversity; abiotic and biotic impact and variation; and supply chain considerations. Observations covers milling and cutting; equipment requirements; and acids including their effects on heavy metals, especially lead. Recommendations summarises key points from this pilot-scale and previous work. These include: harvest seasonality, water quality and proximity to processing facilities; minimising contaminants within the macroalgae such as stones and shells; considering equipment composition and volume for all steps and processes including final product quality; acid choice and its effects on both the equipment used and the metals bioaccumulated within the macroalgae.
