Preservation of fresh coconut gratings by hurdle technique

Hurdle technology employs the intelligent combination of different preservation factors to achieve mild but reliable preservation effects. Fresh coconut gratings treated with different combinations of hurdles such as acidulants, humectants, preservatives, antioxidants, a mild heat treatment and packaging were evaluated for changes in physicochemical and sensory properties. It is possible to preserve the grating for four weeks in laminated polythene packages at 5 degrees C in combination with 3% sodium chloride, 0.3% citric acid, 0.009% sodium citrate, 0.02% butylated hydroxyanisole.
