studied the effect of intermittent drying on beta carotene degradation of squash slice. Their study showed that 87.2% of beta carotene in squash is preserved in intermittent drying while it was only 61.5% in conventional continuous drying. So, improvement of beta carotene retention is 41.78% which is much higher compared to ascorbic acid (33%) discussed previously. They developed degradation kinetics and predicted beta carotene loss considering first order reaction kinetics. The predicted data agreed with the experimental data within ±10%. No other studies investigated beta carotene in intermittent drying. Therefore, more studies needs to be conducted to investigate this for other products.
