Description

一种大黄鱼鱼卵综合利用方法A method for comprehensive utilization of large yellow croaker eggs

技术领域 technical field

本发明涉及一种大黄鱼鱼卵的综合利用方法,属于水产品副产物高值化利用领域。 The invention relates to a comprehensive utilization method of large yellow croaker roe, which belongs to the field of high-value utilization of by-products of aquatic products.

背景技术 Background technique

鱼卵是鱼类水产品加工过程中的主要副产物之一,约占鱼体总质量的10%-30%,主要的加工方式为制作成动物饲料或肥料,其他大部分直接丢弃,存在资源浪费、附加值低以及污染环境等问题。近几年来研究发现鱼卵富含蛋白质、必需氨基酸、不饱和脂肪酸、磷脂等多种有益营养物质,因此,如何充分有效利用鱼卵资源逐渐引起了人们的关注。利用鱼卵资源,不仅能够为消费者提供天然的营养成分,同时还能减少对环境的污染,最终提高企业的经济效益。 Fish roe is one of the main by-products in the processing of fish and aquatic products, accounting for about 10%-30% of the total mass of fish. The main processing method is to make animal feed or fertilizer, and most of the others are directly discarded. There are resources waste, low added value, and environmental pollution. In recent years, studies have found that fish eggs are rich in protein, essential amino acids, unsaturated fatty acids, phospholipids and other beneficial nutrients. Therefore, how to make full and effective use of fish eggs resources has gradually attracted people's attention. The use of fish roe resources can not only provide consumers with natural nutrients, but also reduce environmental pollution and ultimately improve the economic benefits of enterprises.

大黄鱼(Pseudosciaena crocea)属鲈形目,石首鱼科,黄鱼属,俗名黄花鱼、黄瓜鱼、黄鱼等。作为我国八大优势出口养殖水产品之一,大黄鱼不仅肉质细嫩洁白、营养丰富,而且养殖区较集中。除在我国的浙江、广东等省有部分养殖外,大部分集中在福建的宁德和福州沿海地区,仅福建宁德地区年养殖产量就达6-7万t。目前,大黄鱼作为宁德地区主要创汇经济鱼类,除新鲜食用外,大部分采用干燥、腌渍、调味或冷冻等初加工制成产品,远销海内外。而大黄鱼生产加工副产物鱼卵目前尚未得到良好的开发和利用。因此,如何综合利用大黄鱼鱼卵已成为大黄鱼加工中一个关键技术环节,也是闽东地区大黄鱼加工行业函待解决的技术难题。 Large yellow croaker (Pseudosciaena crocea) belongs to the order Perciformes, the family Scrotoaceae, and the genus Yellow croaker. Its common names are yellow croaker, cucumber fish, yellow croaker, etc. As one of my country's eight advantageous export farmed aquatic products, large yellow croaker is not only tender and white, rich in nutrition, but also has concentrated breeding areas. Except for some aquaculture in Zhejiang, Guangdong and other provinces in my country, most of them are concentrated in Ningde and Fuzhou coastal areas in Fujian. The annual aquaculture output in Ningde, Fujian alone reaches 60,000-70,000 tons. At present, large yellow croaker is the main foreign exchange-earning economic fish in the Ningde region. In addition to being eaten fresh, most of the large yellow croakers are processed into products such as drying, pickling, seasoning or freezing, and are sold at home and abroad. However, large yellow croaker production and processing by-product fish roe has not yet been well developed and utilized. Therefore, how to comprehensively utilize large yellow croaker roe has become a key technical link in large yellow croaker processing, and it is also a technical problem to be solved in the large yellow croaker processing industry in eastern Fujian.

大黄鱼鱼卵中鱼油占总质量的25%-30%,鱼油富含二十碳五烯酸(EPA)和二十二碳六烯酸(DHA),是一种极具利用价值的天然-3脂肪酸来源产品。此外,大黄鱼鱼卵富含磷脂,而且其结构中含丰富的DHA或EPA等n-3多不饱和脂肪酸,生物活性较鱼油更有效,可减少冠心病、自身免疫病、高血压、恶性肿瘤、糖尿病和阿尔茨海默氏病等的发病率,提高婴幼儿大脑和视力等,并且生物利用率较高,能更好的被组织吸收。 Fish oil in large yellow croaker eggs accounts for 25%-30% of the total mass. Fish oil is rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It is a natural- 3 Fatty acid source products. In addition, large yellow croaker eggs are rich in phospholipids, and its structure is rich in n-3 polyunsaturated fatty acids such as DHA or EPA. Its biological activity is more effective than that of fish oil, and it can reduce coronary heart disease, autoimmune disease, hypertension, and malignant tumors. , the incidence of diabetes and Alzheimer's disease, etc., improve the brain and vision of infants, etc., and have a high bioavailability and can be better absorbed by tissues.
