Composition/Testing

Testing of shoots by the Midland Fruit & Vegetable Products (I) Pvt. Ltd., New Delhi

Different species were tested for their extractability, i.e. the edible portion portion was extracted after removing the peels and other spoilt portions. The net edible portion was divided by the total weight of the unpeeled shoot to calculate the extractability.

 S. No.

Standard methods were employed to obtain the nutritional composition of the shoots. The methods are listed below:

  1. Moisture : as per AOAC
  2. Ether extract: as per AOAC
  3. Minerals (total ash) : as per AOAC
  4. Phosphorus: as per AOAC
  5. Calcium : as per AOAC
  6. Iron : as per AOAC
  7. Hydrocyanic acid : as per AOAC
  8. Protein : as per SP 18 Part – 1.8
  9. Niacin : by HPLC
  10. Carbohydrates : by difference
