Abstract: The non-therapeutic, cosmetic, oral use of a composition as an active ingredient for whitening and/or lightening the skin and/or depigmenting the skin, in particular for reducing the size of brown spots, including at least cystine and glutathione in a cystine/glutathione ratio ranging from 1.5 to 4, the composition advantageously further comprising glycine and/or glutamine Preferably, the composition also includes at least one component selected from the group formed by zinc or one of its salts, copper or one of its salts, selenium or one of its salts, vitamins B, in particular B3, B5, B6 and/or B8, vitamin E, melon juice extracts, horsetail extracts and mixtures of these components.

Abstract: A keratin hydrolysate including at least 88% by weight of free amino acids relative to the total weight of the amino acids of the hydrolysate and including a content of free tyrosine between 2% and 4% by weight relative to the total weight of the free amino acids of the hydrolysate. Also, a method for preparing the hydrolysate including the following steps: acid hydrolysis, a pH adjustment and a desalination. Also, the use of the hydrolysate for pet food, aquaculture food, and plant biostimulants.

Abstract: A keratin hydrolysate including at least 94% by weight of free amino acids relative to the total weight of the amino acids of the hydrolysate. The keratin hydrolysate includes at least 93% of free valine relative to the total weight of valine in the hydrolysate, at least 90% free isoleucine relative to the total weight of isoleucine in the hydrolysate, and at least 95% of free leucine relative to the total weight of leucine in the hydrolysate. A method for producing the keratin hydrolysate, a composition comprising the hydrolysate and an animal feed containing the hydrolysate are also disclosed.

Abstract: A keratin hydrolysate including at least 88% by weight of free amino acids relative to the total weight of the amino acids of the hydrolysate, the remainder of the hydrolysate being peptides having a molecular mass of less than or equal to 800 Dalton, the hydrolysate also including L-cystine in a content ranging from 4% to 6%, cysteine in a content of less than or equal to 0.1%, and tyrosine in a content of less than or equal to 0.6% by weight, relative to the total weight of the hydrolysate. Also, a process for preparing the hydrolysate, the oral cosmetic use of the hydrolysate for improving the appearance of the nails and/or of the hair, and a dietary supplement including the hydrolysate and optionally vitamins, zinc and/or L-cystine.

Abstract: A hydrolysate including at least 94%, preferably at least 96%, more preferably 100% by weight of free amino acids relative to the total weight of the amino acids of the hydrolysate, the hydrolysate including at least the following amino acids: at least 93%, preferably at least 95%, of valine in free form by weight relative to the total weight of valine in the hydrolysate, at least 90%, preferably at least 95%, of isoleucine in free form by weight relative to the total weight of isoleucine in the hydrolysate, at least 95%, preferably 100%, of leucine in free form by weight relative to the total weight of leucine in the hydrolysate. Also, a method for preparing the hydrolysate and also a starting material and a complete feed for animal feed containing the hydrolysate.

Abstract: The invention concerns a dry feedstuff designed to feed dogs containing at least 35% of proteins relative to dry matter, and/or a protein input more than 110 grams per 1 000 kcal of metabolizable energy, and its use as food, additive or veterinary medicine in particular for controlling excess weight and obesity in dogs.

Abstract: A dry food for dogs that reduces the appetite of dogs including psyllium seeds or parts of sees at a concentration of 0.2% to 4%, based on the weight of the foodstuff.

Abstract: The present invention relates to a food composition for domestic carnivores which makes it possible to prevent or correct pigmentation abnormalities and/or to improve the quality of the fur of the said domestic carnivores, characterized in that it contains a source of free tyrosine representing at least 5% of the total tyrosine supplied. The invention also relates to a method for preventing or correcting pigmentation abnormalities of the fur of domestic carnivores that uses said food composition.

Abstract: The invention concerns a method for inhibiting prebiotic effect of food proteins on the oral bacteria microflora of carnivorous domestic animals, said method consisting in administering to the carnivorous domestic animal an inhibitor of said prebiotic effect, said inhibitor comprising a water-soluble food phosphate. The inhibitor may be administered alone or via a food or a formulation veterinary or not.
