Foods treated with salt or sugar have longer shelf life. Explain the reason for using salt and sugar for food preservation.
a)
Two ways of preventing food spoilage is to store foods in strong salt solutions (brine) and in sugar solutions (syrup). These solutions cannot contain concentrated amounts of solutes (salt or sugar) and are hypertonic to the cytoplasm of microorganisms. Brine and syrup solutions can cause removal of water from the cytoplasm resulting in dehydration followed by death of the invading microbes. Such removal of water is involved in the process of osmosis. Pork, beef and fish meat are some of the food stored in brine. Fruits are often preserved in syrup.
b)
One way of preventing food spoilage is to store foods in strong salt solutions (brine) or in sugar solutions (syrup). These solutions lower concentrated amounts of solutes (salt or sugar) and are hypotonic to the cytoplasm of microorganisms. Brine and syrup solutions can cause removal of water from the cytoplasm resulting in dehydration followed by death of the invading microbes. Such removal of water is involved in the process of osmosis. Pork, beef and fish meat are some of the food stored in brine. Fruits are often preserved in syrup.

One way of preventing food spoilage is to store foods in strong salt solutions (brine) or in sugar solutions (syrup). These solutions contain concentrated amounts of solutes (salt or sugar) and are hypertonic to the cytoplasm of microorganisms. Brine and syrup solutions can cause accumulation of water from the cytoplasm resulting in hydration followed by death of the invading microbes.

drink more water

eat chocolate
