Demineralized tilapia fish scale and hydrolyzed fish collagen peptide脱钙罗非鱼鱼鳞与水解鱼胶原蛋白肽
Indicative specifications for both product families are published below. Final values for your order are confirmed on the batch Certificate of Analysis, and custom specifications can be produced against your own standard.以下为两款产品的参考规格；实际订单参数以批次 COA 为准，也可按贵司标准定制规格。
Demineralized Tilapia Fish Scale (Fish Ossein)脱钙罗非鱼鱼鳞（Fish Ossein）
Dry fish scale is roughly half mineral. Demineralization removes that calcium phosphate fraction under controlled acid conditions and leaves a concentrated collagen matrix — a precursor that is close to pure protein once moisture is deducted.干燥鱼鳞中约一半为矿物质成分。脱钙工艺在受控酸条件下去除其中的钙磷酸盐部分，留下浓缩的胶原基质——扣除水分后接近纯蛋白质，是理想的胶原前体原料。
For collagen and gelatin producers this means a higher extraction yield per tonne of feedstock, lower acid consumption downstream, and a cleaner filtration step than working from untreated scale.对胶原蛋白与明胶生产企业而言，这意味着每吨投料的提取率更高、下游酸耗更低，且过滤环节比使用未处理鱼鳞更洁净。

Hydrolyzed Fish Collagen Peptide水解鱼胶原蛋白肽
Marine collagen is predominantly Type I, the same collagen type that dominates human skin, bone and tendon. Enzymatic hydrolysis cuts the triple helix into short peptides that dissolve instantly and are absorbed as di- and tripeptides rather than bulk protein.海洋胶原蛋白以 I 型为主，与人体皮肤、骨骼与肌腱中占比最高的胶原蛋白类型一致。酶解工艺将三螺旋结构切断为短肽，可即时溶解，并以二肽、三肽形式吸收，而非以大分子蛋白质形式摄入。
We supply two standard molecular weight windows plus custom targets. Lower molecular weight generally improves clarity in beverages and reduces viscosity at high dosage; the 1,000–3,000 Da grade is the usual choice for powders, capsules and gummies.我们提供两个标准分子量区间并可按目标定制。分子量越低，通常饮品中的澄清度越好、高剂量下粘度越低；1,000–3,000 Da 等级是粉剂、胶囊与软糖的常规选择。
