why do processed food last
longer than natural fibre?
Answers
Processed foods can make people's lives easier. Prepackaged foods can reduce meal preparation time. A quick meal can be thrown together using these items rather than ordering out. Food processing extends the shelf life of food which means that food lasts longer with less waste due to spoilage.
Answer:
- due to natural or artificial preservatives added in the processed food ....
or
due to several processes like creating vaccume ....
Explanation:
- processes foods contain preservatives like artificial preservatives and natural :
natural-- vinegar , salt , sugar, oil etc.
artificial-- sorbic acid, butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT).,sodium benzoate ...
these preservatives increase the shelf life of the food by not allowing oxygen to come in contact with the food (oil covers the entire foid material inside which cuts the contact of oxygen with food .. )..
companies also usually create a voccume inside the package by pumping out all the air inside ..which does not allow microbes ,bacteria to survive ..thus increasing shelf life..
