Answer» Solution :i)Artificial sweeterning agents:The chemial substances which are used instead of sucrose (or)sugar are called artificial sweetening agents. E.g:Aspartame,Alitame,saccharin.  i)These desease the calorific intake and the same time sevral sweeter than sucrose. 2)Artificial sweetening agents are very useful to diabetic persons 3)These are harmless. 4)Aspartame is unstable at cooking tamperature so it's use is limited to cold foods and soft drinks, 5) THe sweetening agent used in the prepration so it is stable at cooking temprature. 6) While using alitame as artificial sweeterner,the control of sweetness of food due to microbial growth are called food preservatives.sodium benzote,`C_(6)H_(5)` COONa is the important food preservative used in limited QUANTITIES and is metabolised by conversion into hippuricacid.Which is finally excreted in the urine salts of sorbiacid,propionic acid are also food presevatives. iii) Antioxidants: 1)Antioxidants are important and necessary food ADDITIVES. 2)Antioxidants help in food preservation by retarding the action of oxygen on food. 3)Antioxidants are more reactive towards oxygen than the food material which they protecting. 4)The most familiar anti oxidants are butylated hydroxy toluene (BHT) and Butylated hydroxy anisole(BHA).` 5) The ADDITION of BHA to butter increases its shelf life from months to years. 6)BHT and BHA along with CITRIC acid are added to produce more antioxidant effect. 7)`SO_(2)` and sulphits are useful anti oxidants for wine and beer,sugar syrups and cut,peeled (or) dried fruits and vegetables. |
