Vitamins B1 Supplements

Thiamine (Vitamin B1) is a water-soluble vitamin. It is essential for the utilization of carbohydrates. It is one of the most important members of Vitamins in B-Group.

The addition of sodium carbonate in cooking destructs it. Alcohol, caffeine, sulphur drugs and food processing methods also destroy Thiamine. It is stable in acid medium, and can stand short boiling up to 100 degree C. Hence, it is only partly lost in cooking or canning process.

Thiamine is readily lost from rice during the process of milling. Being a water-soluble vitamin, further losses take place during washing and cooking of rice. Much of thiamine in fruits and vegetables is generally lost during prolonged storage. Thiamine is also destroyed in toast and in cereals cooked with baking soda.
