Characterizing the functional properties of a protein isolate from jackfruit seeds

Researchers from the Autonomous University of Nayarit in Mexico have found that jackfruit seed contains a potential raw material for creating a protein isolate when exposed to ultrasound treatment. In their report, which appeared in CyTA – Journal of Food, the team looked at the process of making a protein isolate from jackfruit seeds and identifies its functional and physicochemical properties.

  • To determine its functional components, the researchers used both an alkaline solution and isoelectric precipitation to fractionate, characterize, and extract the proteins.
  • This was followed by an ultrasound treatment to prepare and determine the physical and chemical properties of the isolate.
  • Based on the tests, the protein had the following properties:
    • Water absorption capacity — 952.1 g/kg (dry basis), 6.42 mL of water per gram of protein
    • Oil absorption capacity — 6.07 mL of oil per g of protein
    • Least gelation concentration — 9 percent at pH 6
    • Greatest protein solubility — 94.4 percent
    • Emulsifying activity — 127 percent
    • Emulsion stability — 127 percent
    • Foaming capacity — 254 percent
    • Stability — 164 percent

From these results, the researchers concluded that the protein isolate derived from jackfruit seeds could be used as a novel protein source.
