[#201] FPO specification for concentration of SO 2 in squashes is
Correct Answer

(B) 350 ppm

Explanation

Solution: FPO specification for the concentration of SO 2 in squashes is 350 ppm. The toxicity of SO 2 increases at high temperatures. Hence its effectiveness depends on the acidity, pH, temperature and substances present in fruit juice. According to FPO, the maximum amount of SO 2 allowed in fruit juice is 700 ppm, in squash, crushed and cordial 350 ppm, and RTS and nectar 100 ppm.

[#202] Fruit type in Pomegranate is
Correct Answer

(C) Balausta

[#203] Papaya latex is preserved using
Correct Answer

(C) KMS

Explanation

Solution: Papaya latex is preserved using KMS . Papaya latex is from the flower of male papaya with main compositions consisting of proteolytic enzymes, papain and chemopapain, glutamine cyclotransferase, chymopapain A, B and C, peptidase A and B and lysozymes. Papaya latex is used since it contains papain enzyme that has been proven for its ability to reduce the solution of silver nitride into nanosilver ions. The latex is mixed with KMS immediately after collection and stored at a cold temperature. It is spread in trays and dried in a vaccum shelf drier for about 4 hours. The dried papain is powdered in a hammer or roller mill and thus preserved.

[#204] Soil binding aromatic crops is
Correct Answer

(D) Vetiver

Explanation

Solution: Soil binding aromatic crops is Vetiver . Vetiver is sometimes applied directly to the skin for relieving stress, as well as for emotional traumas and shock, lice, and repelling insects. It is also used for arthritis, stings and burns. Vetiver is sometimes inhaled as aromatherapy for nervousness, insomnia, and joint and muscle pain. The roots are woven into mats, and hand fans and are also used in air coolers. Vetiver is planted in sloppy areas to prevent soil erosion as it binds with the soil.

[#205] Major Alkaloid in Ashwagandha is
Correct Answer

(D) Withanine

Explanation

Solution: The major Alkaloid in Ashwagandha is Withanine . The biologically active chemical constituents of Withania somnifera (WS) include alkaloids (isopelletierine, anaferine, cuseohygrine, anahygrine, etc.), steroidal lactones and saponins. Withanine, a group of alkaloids isolated from the roots of the plant, forms 38% of the total weight of alkaloids. The principal withanolides extracted from W. somnifera in India were withanolide D and withaferin A which exhibited antitumor and cytotoxic properties.
