Product Description

E.K Herb Feed Grade Tryptophan Powder L-Tryptophan 98% L Tryptophan

Brief introduction
L-Tryptophan is one of essential amino acids and the fourth limiting amino acid in animal diets, which means it could not be synthesized by the body, in addition, dietary supply through feed materials is usually insufficient.
The deficiency of L-Tryptophan was generally characterized as decreased feed intake and efficiency, and slow growth rate. Considering L-Tryptophan playing a key role in growth performance and feed efficiency, it is recommended to add L-Tryptophan in diet to achieve the optimal amino acid balance and fulfill the digestible tryptophan requirement of animals, especially piglets, sows and poultry etc.

FAQQ1: What's the difference between herb extract and powder?A: The extract is a concentrated powder form of raw material. The herb extract's procedure flow is wash, extraction, concentration, purification, drying, grinding, sieving, package. The herb powder is just a powder form of the herb. The procedure flow is wash, drying, grinding, sieving, package.Q2: What's the extract solvent used in the procedure?A: The extract solvent is always depending on the active ingredient in the raw material, regulation and customers' requirement.

Even the solvent other than water used in the procedure, the solvent residue in the extract product also can conform with ICH Q3CR5.Q3: Is there any other ingredient used in the product?A: It depends. For product which is hard to be dried, we need to add some maltodextrin into the extraction solution before drying. The maltodextrin we used is food-class carrier, from non-GMO corn. We can share customer with the ingredient composition table.Q4: How to make sure the quality of the product?A: Firstly, every batch finish product must be tested and qualified before delivery. We can send a specification sheet or CoA for confirmation. The HPLC chromatography graph also can be provided. Secondly, we can provide pre-ship sample to customer for quality confirmation. Q5: Can you develop a new product for us?A: Yes, we can. We have independent R&D dept, who is able to update the procedure parameters of our main products and develop the procedure of new product.
