1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is casein protein hydrolysates.
Casein is a phosphoprotein present in mammal’s milk, and accounts for about 80 % of proteins in cow milk. Different casein hydrolysates (typically containing di- and tripeptides) are available on the market. Differences in composition between different casein protein hydrolysates may exist depending on the manufacturing processes applied. These products generally have a high content of essential amino acids.
A claim on protein and growth or maintenance of muscle mass has been assessed by the Panel with a favourable outcome (EFSA Panel on Dietetic Products Nutrition and Allergies (NDA), 2010). In the current opinion, the Panel addressed whether the consumption of casein protein hydrolysates has any effect on growth or maintenance of muscle mass apart from the well established role of protein on the claimed effect.
The Panel considers that the food constituent, casein protein hydrolysates, which is the subject of the health claims, is sufficiently characterised in relation to the claimed effects.
2.2. Zwiększenie wydolności fizycznej (ID 660, 1497)
The claimed effect is “physical performance”. The Panel assumes that the target population is adults performing endurance exercise.
In the context of the proposed wordings, the Panel assumes that the claimed effect refers to an increase in endurance performance.
Endurance performance relates to the ability to complete certain tasks with higher intensity, faster, or with a higher power output when performing long-term exercise.
The Panel considers that an increase in endurance performance is a beneficial physiological effect.
2.3. Szybsze ustępowanie zmęczenia mięśni po wysiłku (ID 660, 1497)
The claimed effect is “physical performance”. The Panel assumes that the target population is adults performing strenuous exercise.
In the context of the proposed wordings, the Panel assumes that the claimed effect refers to muscle fatigue recovery.
Fatigue can be defined as the loss of peak force or power output. Therefore, muscle fatigue recovery can be defined as the regaining of maximal muscle strength or muscle power after strenuous exercise that has induced muscle fatigue. Regaining muscle strength/power may be beneficial during everyday life activities, and is beneficial for athletic performance in disciplines where loss of muscle strength and power reduces performance.
The Panel considers that faster recovery from muscle fatigue after exercise is a beneficial physiological effect.
3.2. Zwiększenie wydolności fizycznej (ID 660, 1497)
The references provided in relation to this claim either assessed the effects of foods or food constituents other than casein protein hydrolysates (e.g. other protein sources such as whey protein, skimmed milk, soy protein, single amino acids and branched-chain amino acids), or assessed the
effects of casein protein hydrolysates in combination with other food constituents (e.g. carbohydrates) which could have contributed to the claimed effect. The Panel considers that no conclusions can be drawn from these references for the scientific substantiation of the claim.
The Panel concludes that a cause and effect relationship has not been established between the consumption of casein protein hydrolysates and increase in endurance performance.
3.3. Szybsze ustępowanie zmęczenia mięśni po wysiłku (ID 660, 1497)
The references provided in relation to this claim either assessed the effects of foods or food constituents other than casein protein hydrolysates (e.g. other protein sources such as whey protein, skimmed milk, soy protein, single amino acids and branched-chain amino acids), or assessed the effects of casein protein hydrolysates in combination with other food constituents (e.g. carbohydrates) which could have contributed to the claimed effect. The Panel considers that no conclusions can be drawn from these references for the scientific substantiation of the claim.
The Panel concludes that a cause and effect relationship has not been established between the consumption of casein protein hydrolysates and faster recovery from muscle fatigue after exercise.
Warunki i możliwe ograniczenia stosowania oświadczenia
10-30 g protein consumption just before, during or directly after exercise per hour.
