francleanflexy: i dont really know where to post this but if its in the wrong place the admins should pls do the needful.I dn't tink it's just ur finger, even dipping your spoon after a soup has been warmed can spoil it. My theory- when soup is warmed, a thin layer of oil(frm d palm oil or groundnut oil) covers d surface of d soup. Dat layer of oil keeps bacteria causing spoilage in d air frm easily getting into d soup, however, once u insert ur finger or any oda object, it breaks d oil-layer, making d soup expose to bacteria-filled air, hence d more rapid spoilage. Test this- open 2 tin tomatoes, use both half way. Cover d surface of one with cooking oil and leave d oda one(control) like dat. D one covered with oil can last for like 5days or more. It also works for corn beef and sardine 1 Like |

I'm glad i saw this. Some minute ago, my husbby entered the Kitchen and open my pot of okra soup and dip his finger to pick a meat, then i said, hum, if this soup get sour, He told me it cant get sour. He said what makes soup get sour is saliva not the finger. After putting ur hands in ur mouth and den dip it back into the pot, the saliva in ur finger will have contact with the soup and makes the soup start digesting. Hope this is true? |

mstik: Your hands are naturally covered with bacteria. Remember when the soup is cooked, the heat kills of all the bacteria that are possibly in it so when you dip bacteria infested fingers into the so pot, bacteria gets into the soup and they begin their work of decomposing and then by the next morning, it would have spoilt.u saying we wash with dettol before fishing from d pot remember dettol kills bacterials |

Re: What Is The Science Behind Soup Spoilage Due To finger.ing by abdulahi001: 11:57am On Jul 26, 2014 |
yousee: I definitely know that soup will boil beyond 110 degree C, because the pepper, oil,maggi,onion e.t.c will serve as impurities which will increase d boiling point and more so, O-H bond present in water makes it boil faster than C-H bond in oil and other ingredients of soup. Well, my thoughts are theoretic, you can get a thermometer and get same quantity of water and soup and boil,for comparison. My #2kobo |

abdulahi001: This is my thought!!!Na u dey wrong Nobody put hands into hot soup, they only do when the temp has gone down and comfortable to accomodate germs/bacteria |
Re: What Is The Science Behind Soup Spoilage Due To finger.ing by xtervaganza(m): 12:40pm On Jul 26, 2014 |
Let me explain what may cause it from my little knowledge....... When u warm your soup all or most of the bacterias that are supposed to make it sour/spoil will die due to the heat. So when the soup cools off, the upper part forms a shield, like a blood clot on a wound, thereby shielding new bacteria's from entering the soup or reduces their impact on the soup The finger u dip in the soup opens the soup, its like you left an outlet for the bacteria's to enter, like an open wound By this(I think) the bacteria's would get in through the small opening and you and I know how fast they multiply and attack ur soup Lol 1 Like |

lilTunechi: According to jacques hindleberth, When soup is heated to a certain degree the heat rays evaporates and locks the eminent exposure to the fish or meat inside the pot..... Uhghh, I have no idea what I'm saying.! Sorry I kinda imagined u saying this with a British accent... *laff wan kill me die* |

abdulahi001: This is my thought!!! Guy... Update! There are bacteria that can survive that, biko!... Thermophilic ones for that matter... but sha they cant find their way to ur stew... except stew inside active volcanic mountain...so no fear |

It is not the finger you put in the soup, but the bacteria on the finger you put in the soup. A pot of soup you fiddled with your finger would not sour provided that it was sufficiently hot when you did it, because the heat still trapped in it would destroy the bacteria/fungus. On the other hand, when warmed and allowed to cool down to room temperature before fiddled with your finger, would sour because the temperature in the soup was not hot enough to kill the germs. |

sambisa5: ..Stew is made of more oil(vegetable to be precise) and that oil is more of a preservative. As far as i can remember, my mom doesnt use vegetable oil to prepare egusi soup. LAST BULLET: stop dipping your hands in MOM's pot |
