適用範囲

This standard applies to the feed additive calcium salt of hydroxyl analogue of methionine, produced primarily from hydroxyl analogue of methionine and calcium hydroxide. It is mandatory for manufacturers producing this specific feed additive for the Chinese market. The standard does not apply to other forms of methionine or unrelated feed additives.

技術要求

The standard specifies the physical and chemical requirements for the calcium salt of hydroxyl analogue of methionine. Appearance requirements dictate that the product must be a white, light gray, or gray-brown powder or granule with a characteristic odor. Key technical indicators include minimum content limits for the calcium salt and the hydroxyl analogue of methionine on a dry basis. It also sets specific ranges for calcium content and maximum limits for loss on drying, heavy metals (as Pb), and total arsenic (As). Packaging and storage requirements mandate that the product must be protected from light and moisture. Under specified storage conditions, the product has a shelf life of 24 months. Labeling must comply with GB 10648.

試験方法

The standard outlines several testing procedures, including sensory inspection for appearance and odor. Identification tests involve chemical reactions and High-Performance Liquid Chromatography (HPLC) to confirm the presence of the hydroxyl analogue of methionine. Content determination is performed using potentiometric titration. Additional tests for loss on drying, calcium content, heavy metals, and total arsenic are conducted in accordance with referenced national standards such as GB/T 6435 and GB/T 13079.

よくある質問
