so labeling makes ppl think it’s somewhat better Video 10 - Shirriff mashed potatoes from a box labeled “Made from real potatoes” - has anti-oxidants à sodium bisulphite, sodium sulphite, sodium acid pyrophosphate, BHT, BHA, citric acid - oxidants react w food à browning of fruits & veggies; oxidation of fats (rancidity) - antioxidants prevent this - when cut an apple, the metal in knife promotes oxidation of chemicals in apple - want something that will trap the metal to prevent it from interacting w the food

à citric acid acts as a chelating agent (aka. sequestrant ) - traps/chelates the metal ion that would react w the food (causing browning) - mayonnaise has calcium disodium EDTA which is a sequestrant - sodium bisulphite (Na 2 SO 3 ) is an additive to prevent browning - some ppl are allergic to sulfite & 20 ppl died in US before danger was known - sulphites added to salad bars to prevent potato salad from browning - today, sulphites used in grapes to keep crunchiness; use in pre-cut fries - used as anti-microbial in wine to prevent it from going bad - in Canada, only 1 case from reaction to sulphite à asthmatics most susceptible - the person prepared raisin bread & added dried raisins (preserved w sulphites) - BHA & BHT prevent rancidity to prevent oxidation of fat - added to cereals (to the packaging ) to preserve freshness - free radicals promote fat oxidation - free radical takes the H in BHT & leaves behind a transformed BHT which is stable & prevents a free-radical chain reaction - rats fed large amount BHT develop liver abnormality , but live 25% longer - diet high in BHT can make us live longer à aging process possibly due to oxidation process - potato chips à sunflower oil, BHA, BHT Video 10 - white bread has calcium propionate (a preservative) - used in rye to prevent ergot (assoc w ergot poisoning & St. Anthony’s Fire) - ergot has a chemical similar to LSD; ergot poisoning causes hallucination - last case of ergot poisoning in Pont St. Esprit in 1951 - Swiss cheese has holes - propionibacterium shermanii bacteria acts on lactic acid to produce propionic acid & CO 2 - Swiss Cheese makes its own preservative à propionic acid (20X greater than what is added to bread) à calcium propionate is converted to propionic acid when added to bread - in Europe, no preservatives are needed for bread bc it’s not kept for any length of time Video 11: Conclusion - Black Tower “German Wine” (actually a blend of wines from many European Countries) - ice cream à guar gum, carob bean gum, carboxymethylcellulose, carrageenan, gum Arabic - bc there’s no cream, gums are added for texture - carboxymethylcellulose prevents formation of ice crystals by absorbing moisture - when open freezer, moisture comes in & causes ice crystals - radishes & celery contain goitrogens , which may lead to development of goiter - cheese has tyramine that can cause high blood pressure (headaches) - oranges have tangeritin which is embryotoxic (potential birth defects) - carrots have myristicin , a hallucinogen - bananas have serotonin which can lower the sex drive - apples have phlorizin ,
