The chapter explains how mangoes ripen, how they spoil, and how food can be preserved to last longer.
Mangoes spoil because germs grow on them, especially in hot and humid weather
A spoiled mango may have:
• Black spots
• A bad smell
• Soft or mushy parts
• A sour or rotten taste
Mangoes ripen when they get warm. Heat makes them turn yellow and sweeter.
Food preservation means keeping food fresh for a longer time by using methods like drying, adding salt, sugar, or refrigerating.
Drying removes water from mango pieces, and germs cannot grow easily without water.
• Bad smell
• Change in colour
• Soft or watery texture
• Fungus or mould on food
Spoiled food can make us sick because it contains harmful germs.
Water helps germs grow, so pickle jars must be dry to prevent spoilage.
