years‚ as there wasn’t any need for such a biopolymer; petroleum was still inexpensive and abundant so PHB was unnecessary.

PRODUCTION OF CITRIC ACID Introduction: Citric acid is a White solid‚C3H4OH(COOH)3‚soluble in water and slightly soluble in organic solvents‚ which melts at 153 oC. Aqueous solutions of citric acid are slightly more acidic than solutions of acetic acid. Traces of citric acid are found in numerous plants and animals‚ because it is a nearly universal intermediate product of metabolism. Large amount of the acid are found in the juice of citrus fruits‚ from which it is precipitated by the

Explain the use of enzymes in food production by means of examples. You must include the example of lactase. Enzymes are proteins that speed up the rate of chemical reactions (up to a million times) in living organisms. Acting as catalysts they are not consumed nor altered in the process of converting the specific set of reactants into specific products. In food production‚ enzymes are greatly appreciated by their accelerated effect in biochemical processes and are mostly used in what we

A forecast is a statement about the future. Features common to all forecasts 1. The same underlying causal system that existed in the past will continue to exist in the future. 2. Forecasts are rarely perfect; actual results usually differ from predicted values. 3. Forecasts for groups of items tend to be more accurate than forecasts
