Principles of Chemical Preservation of Food

Substance which is/ may become a part of food A substance or a mixture of substances which is present in food as a result of any aspect of production, processing, storage or packaging A substance, the intended use of which results or may reasonably be expected to result in its becoming a component or otherwise affecting the characteristics of any food with certain exceptions All of the mentioned Food items that find their way accidentally or unintentionally Pesticides, color additives New animal drugs or any substance used in accordance with a sanction or approval granted prior to effective date of food additives amendment of 1958 All of the mentioned Maintenance of nutritional quality of food and providing essential aids in food processing Enhancement of keeping quality or stability with resulting reduction in food losses Making food attractive to the consumer in a manner which does not lead to deception All of the mentioned To disguise the use of faulty processing and handling techniques To deceive consumers and result in a substantial reduction of the nutritive value of the food When the desired effect can be obtained by good manufacturing practices which are economically feasible All of the mentioned Preservation Serve as nutritional supplement Color modifiers All of the mentioned Brandy Olestra Baking Soda None of the mentioned True False True, False True, True False, False False, True Propionates Sulphur dioxide Propionates & Sulphur dioxide Neither of the mentioned True False All food items consumed by man are radioactive Alpha and beta particles and gamma photons are the radiations available for food preservation applications Energy lost per ion pair formed is greater than the ionization energy All of the mentioned High ionization due to relative size and carrying of double positive charge Low penetration power In air, they have a range of few centimeters All of the mentioned High specific ionization ability Low penetrating power Higher ionization ability than gamma radiation All of the mentioned Fission products require extensive shielding and dose supplied may be so high that prolonged exposure times are required Machine produced radiations are unidirectional and can be turned off None of the mentioned Neither of the mentioned Cobalt glass Colored plastic tapes Ferrous dosimeters All of the mentioned
