Food science and Technology Short Definitions Contaminants are any harmful substances accidentally or intentionally added to food, that make it unfit for consumption. Double fortification and multiple fortifications refer to the addition of 2 or greater than 2 nutrients respectively to a particular food. Enrichment is a method of restoration of vitamins and minerals lost during process. (Hoffpauer and Wright, 1994). Food Additive may be a substance that is not consumed as a food by itself, but is added to food to boost its functional, physical and sensory attributes or to preserve it. Quality Assurance (QA) is the process of planning, documenting and agreeing on a collection of guidelines that are necessary to prevent contaminants from entering into the food right from the procurement of raw materials to the distribution of the finished product. Quality Control (QC) refers to all activities that are designed to determine the level of quality of the delivered food product. It invo...

Possible Side Effects of Drinking too much Water Swells up your cells Sodium and potassium ions in your body maintain the fluid balance between the cells and also the blood. However, once there's excess water within the blood and salt and ions within the cells, water rushes into the cells and swells them up. this can be risky for your nerve cells of your brain due to the restricted area within the skull and may result in seizures, headaches and brain injury. Low Potassium levels Low potassium levels are another side effect of over hydration. this could cause symptoms like vomiting, low blood pressure, nausea, and diarrhea. thus if your body is in a state of water retention, its best to not drink a lot of water. Low sodium levels Drinking an excessive amount of water will disturb your body's overall sodium balance. Critically, it should be 145 m Eq/L however when it goes lower than 135 m Eq/L, it may result in the swelling up of cells due to an excessive amount of water. in case...

Effects of Beverages on Digestion Eating and Drinking together To drink a beverage while eating is really not necessary, and it could upset digestion generally. whether the drink is hot or cold, it's better to save it for after you have eaten  completely. according to Raw Food Explained.com, the drink interferes with digestions as a result of the digestive liquid and enzymes get carried out with the drink instead of staying in the stomach. Also, taking a swig of a drink may wash down food that has not been properly broken down through chewing and mix with saliva within the mouth. Cold Beverages Slow Digestion According to Susan E. Brown, PhD, cold foods and beverages slow down the speed of digestion as a result of they must be "heated up" before proper digestion can take place. Cold beverages are removed from the stomach more quickly. Those at room temperature keep in the stomach longer. that's why marathon runners attempt to hyperhydrate and drink cold water before a...
