What changes did you observe in the fruit? Can you think of a way to preserve items like tomato?
(i)
Answer
The tomato slices shrink, become dry and wrinkled, and change colour from bright red to darker red or brownish. The texture becomes leathery as water evaporates.
(ii)
Answer
Tomatoes can be preserved by sun-drying, making tomato paste or puree and refrigerating, pickling with oil and spices, or canning as sauce or canned tomatoes.
Explanation
(i) When tomatoes are placed in sunlight, the heat causes water to evaporate, leading to visible changes in size, texture, and colour. (ii) The chapter discusses multiple preservation methods: drying (removes moisture), refrigeration (slows microbial growth), pickling with oil (keeps out air), and canning (keeps microbes away).
