紫菜是广大群众喜爱的海味品之一。近年来,由于质量欠佳,销路不畅。因而,提高质量就成了能否巩固发展紫菜养殖的关键问题。影响紫菜成品质量故然与加工不当有关,主要的原因还是鲜菜本身品质低劣。北方养殖的条斑紫菜由单孢子进行无性繁殖的世代,能不断地长出新的幼嫩藻体以取代衰老的藻体,故在整个养殖生产过程中,都能采到幼嫩的藻体,保持成品质量始终优良。而南方各省养殖的均为坛紫菜,它没有单孢子世代,因而只在第一、二水时能采到幼嫩的鲜菜,成品质量较好,以后随着藻体的衰老,鲜菜质地越来越差,成品质量也相应地一水不 Seaweed is one of the seafood favorites of the masses. In recent years, due to poor quality, poor sales. Therefore, improving the quality has become the key issue to consolidate the development of seaweed farming. Affect the quality of laver finished product quality and improper processing, the main reason is the poor quality of fresh vegetables itself. Porphyra cultured in the North by a single spore clonal propagation of generations, can continue to grow new young algae to replace the aging of the algae, so throughout the farming process, can be taken to young algae , To maintain the quality of finished products has always been excellent. The southern provinces of the breeding are algae seaweed, it does not single-spore generation, and therefore only in the first and second water can be taken to the tender fresh vegetables, finished better quality, later with the algae aging, vegetable texture Getting worse, the quality of finished products is also a water not
