The government does routinely inspect the food manufacturing companies with products that have this problem.Vitamin questionsThat makes me ask my self. They know the exact deterioration rate on all their products, and therefore they can predict the deterioration rate of new and similar products.Food And Vitamin Loss Over TimePosted by nick_niesen on October 26th, 2010You know the claim on food value from the label that is stuck on it; let's pick a nutritious drink product and on that drink is some nutritional claim that states it has a shelf value of two years.

What it means is that the manufacturer had to put an overage of that vitamin in the product because the vitamins will deteriorate over a period of time. Usually the higher the temperature the higher rate of deterioration, and the longer it is stored means something too..Food companies have documentation on all food products that they have manufactured.200% of vitamins in the productSo if they want the product to contain 100% of vitamin C after 2 years, Vitamin D3 Manufacturers then they have to put 200% of vitamins in the product, because of the deterioration that takes place. 2 years later it will have lost half of its value, and contain the claimed amount. It protects the product during the shelf life.

Vitamin C is the most sensitive vitamin. What the food companies and food scientist does when the product is formulated they will add an overage of vitamins and minerals. After those two years that product still needs to contain 100% of the vitamin C level. That means that a new nutritional beverage formula can be based on the level of a know products nutrition values.Vitamin deteriorationThat does not mean that when the drink product was manufactured it contained 100% of vitamin C and after the two year has gone, it only contain half that level of vitamin C. Can I trust that the food I buy from the store has the nutrition value that it claims? Can I feel sure that my body gets all the vitamins it must have to function? I say better be safe than sorry!Thank you for your time
