1. Why are some fruits sweet and some sour, whereas others have no specific taste
Some fruits such as watermelon, guava, grapes, apples, mangoes, etc. are sweet while the lemon flavor, mango orange, premiums, etc. are sour. Each fruit has a different flavor. That differs somewhat from the taste of any fruit. In fact, the taste of a fruit depends on the compounds present in it. In general, fruit contains fructose (natural sugar), organic acids, vitamins, starch, protein, minerals and cellulose. All these materials are in a mixed state in the fruit and are found in different proportions in different fruits. A fruit having more fructose usually contains sweetness, while those with more acidic bitterness. Orange is a fruit that is nearly equal amounts of fructose and acid therefore, has a sweet and sour In general, fruits contain more acidic, but in maturity, the amount of acid in them decreases and the amount of sugar (Feldkamp, 2002).
Therefore, the raw mangoes are bitter, but the mature ones are sweet. Raw bananas contain more starch, but are converted to fructose, when the fruit ripens. During the maturation process, chemical changes take place within the fruit by which increases the amount of sugar and the sweetness of the fruit. We realize the difference in taste, even in two fruits of the same class. Two apples or mangoes two do not always taste the same. This is because there are many varieties of the same fruit and changes in soil quality, climate, cultivation techniques, fertilizer, water, etc. to change the ratio of compounds in the fruit resulting from the difference in taste. Acidic fruits like lemons, not the sweet taste, even after they are ripe, due to the presence of excessive amounts of acid (Hulme, 20007).
