3. Adjust the food. Or the circumstances of food to inappropriate effects on growth of microorganisms and other causes
microbial contamination in food. When A phase by phase, growth period to adapt (lag phase) recently increased slow
.Because microorganisms to adapt to the environment. When through the recently, will enter the period of increase (growth phase) which
.Microorganisms are an increasing number of fast logarithmic until there are enough to cause the food deterioration, or
.What food poisoning after passing through the recently, would be a constant (stationary phase) rate increase จำนวนและ death
.Microorganisms are equally because microorganisms with large quantities, began to build waste, toxic to environment unsuitable. The
.After enters the phase constant microbial death (death phase) which the microorganisms start reducing mortality than adding
number. Because the toxins accumulating more
.If microorganisms in a suitable environment for growth, such as a nutrient rich มีน้ is enough, atmosphere and temperature
.To some extent, make center shortened into distance preservation. Do with adjustment of food, or the circumstances of the food
to unsuitable for the growth of microorganisms is a stretch phase adjustment for longer
.The adjustment of the pH of food, such as adding acid or the acid fermentation The acid generated from microorganisms during fermentation, such as
lactic acid (lactic acid) acetic acid (acetic acid) inhibit microbial growth, other types not
.The devaluation Wateractivity (water activity aw), by reducing the amount of water in the food drying (dehydration) making
concentrations. (concentration) or put the solute, such as salt or sugar to increase the osmotic pressure (osmotic pressure)
.Food, which method, including fixation or marinated with salt (salt curing) or agitation. The welding immersion full, with a high concentration sugar
. Reducing the temperature
.Removal of air or oxygen removal, such as vacuum packaging (vacuum packaging) and atmosphere control
(controlled atmosphere. Packaging) or modified atmosphere (modified atmosphere packaging)
