         12 . The product according to  claim 8 , wherein the additive is selected from the group consisting of lactobionic acid, lactobionic-δ-lacton, a salt of lactobionic acid and mixtures thereof. 
     
     
         13 . The product according to  claim 8 , wherein the additive is selected from the group consisting of acidic flavours, fruit flavours, sweet flavours, savoury flavours, salty flavours, a high intensity sweetener, a sugar alcohol, sucromalt, ribose, tagatose, trehalose, organic acid, fruit extract, a bulk sweetener, a fibre, a prebiotic agent, a thickener, a vitamin, a mineral, a preservative, a food colour and a therapeutic agent. 
     
     
         14 . The product according to  claim 8 , wherein the additive is selected from the group consisting of creatine, polyphenole, L-carnitin, omega-3 polyunsaturated fatty acid, omega-6 polyunsaturated fatty acid, green tea extract, EGCG (epigallocatechingallate), aminoacids and peptopro. 
     
     
         15 . The product according to  claim 8 , wherein said product is a food, an animal feed or a pharmaceutical product. 
     
     
         16 . The product according to  claim 8 , wherein said product is a jelly, a beverage, a fruit preparation, a fruit juice concentrate, a fruit juice or a smoothie. 
     
     
         17 .
