Information
The decomposition of food is a chemical change caused by different factors.
A food can have three types of pollution:
BIOLOGICAL:Pollution is more common, and occurs in any stage of a food consumption. Since the produce may be contaminated with pathogenic microorganisms or molecules that hydrolyze essential food and rancid, as in the manufactured, packaged and sold if these are lacking in adequate sanitary conditions.
CHEMICAL:This contamination is to add substances to foods which are intended to alter a chemical. Some unapproved additives such as artificial colors, are a chemical contamination. These contaminants may be toxic or exacerbating, allergens among others
PHISICS:Rancidity is caused by depletion of food or for bad conditions of temperature, pressure and others
What happens when you eat decaying food?
Nausea
Diarrhea
Abdominal pain
Infections caused by viruses, bacterias or parasites
Vomiting
Cold
Table of dehydration that could lead to death
What we have to do before eating a meal…
Wash hands
Wash the meal if its a fruit or vegetal
Chek experation date
Detoxify
Conservetion Methods
By Heat:Pasteurization: The process of pasteurization was named after Louis Pasteur discovered that contaminating organisms producing wines disease could be eliminated by applying temperature. Sterilization: Sterilization is performed by the water vapor pressure
By cold:Freezing food is subjected to temperatures below freezing (at - 18 ° C) for a short time. Cooling: the food is maintained at low temperatures. Freezing: the food is subjected to a temperature between -35 and -150 º C for a short period of time. It is the best procedure for applying the cold as the ice crystals that form during the process are small and fail to damage the tissues of the food.
Escaldes:Pasteurizitation. U.H.T . Sterilization.

Photo #1
This is The Photo of what happen the first Day on the apple :(
Well nothing happens it looks the same :/
Day #1 :) Of Experiment
We left the apple in half and got into the box and put it under the bed where the light can not reach
:) Objective of Experiment
A few days ago we did an experiment about what would happen if we put an apple in a box in a dark place ?.... put the apple in a box for four days:)

definition of descomposition
Definition: The decomposition of food is a chemical change caused by different factors.
hypothesis and method
Objective: To demonstrate that the decomposition of food by an experiment.
Knowing the consumption effects
Hypothesis: What breaks down food?
Method: To investigate everything asked of our subject, interview people , and after that do an experiment to expose.
