molecules is a group of atoms joined by bonds and stores chemical energy 

carbon to carbon
carbon to hydrogen 

everything is made of cells and all cells are made of molecules and molecules are made of atoms 

carbohydrates are made up of oxygen hydrogen and carbon 

fats are still made of oxygen hydrogen and carbon they are just organized differently

proteins are made of hydrogen carbon oxygen and nitrogen

minerals nitrogen phosphorous calcium sodium

-
We blanch to stop enzyme activity
heat can denature proteins

Enzymes can cause undesirable changes in vegetables
   
 Blanching
inactivation of enzymes 
reduction of microbial contamination 
air removal
preheating 
cleaning
softens tissue 
//// A certain temp has to be applied through out the food for it to deactivate the enzymes 

things that impact how fast the center heats up 
heat source
size and shape 
thermal conductivity 

1. steam blanching 
2.hot water blanching 

if you blanch to long the food will start to cook 

Pasteurization

applies heat to destroy pathogens for liquids

145f for 30min vat pasteurization 

161f for 15sec  high temp short time 

Homogenization 
brake down the fat to get even without 

frying 
baking 
canning
roasting
steaming
sterilization

High temp 

killing microbs
 
Some organisms can survive prostration thermouduric/thermophilic 

Sterilization 
the destruction of all viable organisms in food as mesured by high enough temp

time and temp depends on the food 

some organisms are resistant to heat 

heat gets better with a decrease in moisture 

longer the better for killing higher the better for killing

before we freeze we blanch to stop the enzymes 
removes execs air and helps pack it tightly
vacuum packing can help prevent freezer burn and spoilage  
store at 0f or lower
packing heavyweight materials moisture resistant materials
dont overload your freezer 
eave a little space in between packages so hair can circulate freely
