Key Points For Selecting High-Purity Hydrolyzed Milk Protein
Feb 25, 2026
For different application scenarios, the requirements for high-purity hydrolyzed milk protein vary. When purchasing, it is necessary to make targeted choices to fully utilize its maximum efficacy. The specific key points for selection are classified according to application scenarios as follows:
Enterprise Formula Procurement (Functional Food/Nutritional Supplement Scenario)
Prioritize choosing manufacturers with qualifications and core technologies, and require them to provide complete test reports (covering key items such as purity, hydrolysis degree, impurity content, and microbial indicators).
It is necessary to make precise selections based on the product positioning:
- For infant formula, choose products with deep hydrolysis, high purity (≥95%), and low allergenicity, and they must comply with EU EFSA or Chinese national standards. For example, Arla Foods Ingredients' Peptigen® IF-3080 has been certified by EFSA and can be directly used in infant formula;
- For adult nutritional supplements, adjustments are made according to the target population. Post-operative recovery populations and the elderly are suitable for deep hydrolysis products, which facilitate digestion and absorption;
- Fitness enthusiasts can choose partially hydrolyzed products with high bioactive peptide content to assist in muscle repair.
At the same time, attention should be paid to the solubility and stability of the raw materials to ensure they can be adapted to the formulation system of the own product and avoid compatibility issues.
II. Personal Consumers' Purchase (Finished Supplement Scenario)
The key point is to prioritize choosing products from reputable brands with clear ingredient lists and the ability to provide test reports, and to avoid unmarked products.
Match precisely according to individual needs:
- For those with weak digestive function, post-operative recovery individuals, and the elderly, it is recommended to choose deep hydrolyzed protein oral liquids or powders to reduce the burden on the stomach and intestines;
- For fitness enthusiasts, it is suitable to choose hydrolyzed protein powder, which can be combined with carbohydrates for optimized absorption;
- For people with a high risk of milk protein allergy, it is necessary to strictly choose products clearly labeled as "low allergenic" or "deep hydrolyzed", and it is essential to use them under the guidance of a doctor or nutritionist to avoid the risk of allergy.
In addition, be vigilant about products that add excessive sugar, flavoring, and preservatives, especially for infants and sensitive individuals. The simpler the ingredients, the safer it is.
III. Cosmetics Formula Procurement Scenario
It is necessary to select products with a purity of ≥ 90%, that have undergone strict purification treatment and have no residual impurities. Preferentially choose raw materials that are mild and non-irritating and can be adapted to the cosmetic formulation system. Avoid causing irritation to the skin or hair.
Based on the product's efficacy:
- For moisturizing and repairing skincare products, priority can be given to products with a high content of small peptide segments. Small peptides are more easily able to penetrate the skin and exert moisturizing and barrier repair functions.
- For hair care products, it is suitable to choose products that have both nourishing effects and anti-static properties, helping to improve hair quality and reduce frizz.
At the same time, attention should be paid to the stability of the raw materials to avoid chemical reactions with other components in the cosmetics, which may affect the quality and usage effect of the product.
