The major component is whether likely to be safflower oil, canola oil, or soybean oil has to be identified and explained.

Concept introduction:

Fats are triglycerides made up of one glycerol molecule and three fatty acid molecules. They are also considered as the hydrophobic substances which are soluble in the organic solvents and insoluble in water.

Saturated fats are the one which contain saturated fatty acids in it and it cannot be hydrogenated.

Unsaturated fats are the one which contain unsaturated fatty acids in it and it can be hydrogenated further.

(b)

Interpretation Introduction

Interpretation:

Vitamin E is whether a part of the oil itself oran added component has to be given.

Concept introduction:

According to the solubility, vitamins can be classified into two:

• • Water soluble vitamin
• • Fat soluble vitamin

Water soluble vitamin:

• • Found in the aqueous environment inside the cells.
• • They have $-\text{OH},-\text{COOH}$ or other polar groups which make them water soluble.
• • Some water soluble vitamins are incorporated into coenzymes.

Fat-soluble vitamin:

• • Mainly they are stored in the body’s fat deposits.
• • Vitamins A, D, E and K are examples.
• • Over dose of these vitamins is hazardous since they accumulate in body fats.
