Moisture content was evaluated based on the weight loss of a 5-g sample during oven drying at 105 °C for 1 h under atmospheric pressure and was expressed as percentage (%) of the total weight. Aw was measured with 7.5 g of sample using a Novasina IC-5000 AW-LAB water activity analyser (Novasina AG, Lachen, Switzerland). All assays were performed in triplicate.
