Research Question: How the amount of vitamin C in fruit juices affects its freshness and till what extent is the information provided on the pack by manufacturers is reliable? Background Information: Hypothesis: -fresh juices have more vitamin C than long-life -juice that is ‘not from concentrate’ is best in terms of vitamin content -if heat destroys vitamin C then heat-treated long-life juices will have lower concentrations -if heat destroys vitamin C then boiled fruit juice will have

classes of vitamins are Fat – soluble vitamins and water – soluble vitamins. Fat – soluble vitamins include vitamin A‚ vitamin D‚ vitamin E‚ and vitamin K. These vitamins are considered fat soluble vitamins because they are stored in the body for long periods of time and are harder to break down‚ while water soluble vitamins are not. Water – soluble vitamins include vitamin B1 (thiamin)‚ vitamin B2 (riboflavin)‚ vitamin B6‚ vitamin B12‚ and vitamin C‚ folic acid‚ and niacin. These vitamins are classified

VITAMINS AND MINERALS Vitamins and minerals make people’s bodies work properly.

The water-soluble vitamins — C and the B-complex vitamins (such as vitamins B6‚ B12‚ niacin‚ riboflavin‚ and folate) — need to dissolve

Vitamins and Minerals What are vitamins? Vitamins are nutrients that everyone needs in small amounts for the body to work properly. Different vitamins have different functions. For example‚ some enzymes need particular vitamins to work. Your body can’t make most vitamins apart from vitamin D‚ so you have to get them from the food you eat.
