A Qingdao trading house built around one narrow category一家专注于单一细分品类的青岛贸易企业
QINGDAO SINOVO INTERNATIONAL TRADING CO.,LTD exports demineralized tilapia fish scale and fish collagen peptide. We deliberately keep the catalogue small so that specification control, documentation and repeat-lot consistency stay under our direct supervision.青岛信诺立国际贸易有限公司专业出口脱钙罗非鱼鱼鳞与鱼胶原蛋白肽。我们刻意保持精简的产品线，从而将规格控制、文件准备与批次一致性置于我们的直接管理之下。
Ingredient specialists, not a general trading catalogue专注原料，而非综合贸易
SINOVO (Xinovo) is based in Qingdao, Shandong — China's largest cluster for aquatic product processing and export. Our team sits between the fish processing plants that generate scale and the collagen, nutrition and cosmetic manufacturers that need it in a defined, repeatable specification.信诺立位于中国山东青岛——中国最大的水产品加工与出口集聚区。我们的团队处于产出鱼鳞的水产品加工厂与需要稳定可复制规格的胶原蛋白、营养品与化妆品制造商之间。
That position lets us do two things a broad-line trader usually cannot: hold a consistent specification across repeat lots, and answer technical questions about moisture, ash, nitrogen, molecular weight and odour without going back down the chain for every enquiry.这一位置使我们能够做到综合贸易商通常无法实现的两点：在多个批次之间保持一致的规格，以及在无需逐单回溯产业链的情况下直接回答关于水分、灰分、氮、分子量与气味等技术问题。
We work in English and Chinese, quote FOB Qingdao, CIF and CFR terms, and serve both first-time buyers testing a container and established manufacturers adding a second source of supply.我们以中英双语沟通，可按 FOB 青岛、CIF、CFR 条款报价，既服务首次试柜的新客户，也服务需要增加第二供应源的生产企业。
From scale to sealed bag in six controlled steps从鱼鳞到成品，六个受控环节
Scale collection鱼鳞收集
Fresh scales are collected from partner freshwater and marine fish processing plants, chilled or dried within hours of filleting to protect protein quality.从合作的淡水与海水鱼加工厂收集新鲜鱼鳞，在去片后数小时内冷藏或干燥，以保护蛋白质品质。
Sorting & washing分选与清洗
Scales are graded, repeatedly washed to remove flesh, sand and pigment, and screened for foreign matter before drying.鱼鳞进行分级，反复水洗去除鱼肉、泥沙与色素，干燥前进行异物筛选。
Acid demineralization酸法脱钙
A controlled acid step removes the calcium and mineral fraction while the collagen matrix is preserved, followed by neutralization and water rinses.通过受控酸处理去除钙与矿物质成分，同时保留胶原基质，随后进行中和与水洗。
Enzymatic hydrolysis酶解
For peptide grades, food-grade proteases cut the collagen into short chains; the reaction is stopped at the target molecular weight window.生产肽类产品时，使用食品级蛋白酶将胶原蛋白分解为短链，在目标分子量范围内终止反应。
Filtration & spray drying过滤与喷雾干燥
Decolourization, deodorization, membrane filtration and sterilization precede spray drying into a free-flowing, instantly soluble powder.经过脱色、脱味、膜过滤与灭菌后喷雾干燥，制成流动性好、即溶的粉末。
QC & export documentation质检与出口文件
Every lot is tested and released with a COA; export documents, health certificates and customs paperwork are prepared in parallel.每批产品经检验并随附 COA 放行；同步准备出口文件、健康证明与报关资料。
What we test, and what we send you我们检测什么，以及提供什么文件
Routine release testing常规放行检测
- Protein / total nitrogen, moisture, ash and pH on every lot每批检测蛋白质（总氮）、水分、灰分与 pH
- Average molecular weight distribution for peptide grades肽类产品的平均分子量分布
- Heavy metals — lead, arsenic, cadmium, mercury重金属检测——铅、砷、镉、汞
- Microbiology — total plate count, coliforms, salmonella, E. coli, yeast and mould微生物检测——菌落总数、大肠菌群、沙门氏菌、大肠杆菌、酵母与霉菌
- Sensory checks on colour, odour and solubility against the approved sample对照确认样进行颜色、气味与溶解性感官检查
Documents supplied with each shipment随货提供的文件
