Effect of microwave vacuum drying and hot air drying on the physicochemical properties of durian flour

Abstract: Unripe durian cv. Monthong was subjected to microwave vacuum drying (MVD) at 1200, 1600 and 2200 W and hot air drying (HAD) at 40, 50 and 60°C to produce durian flour. Drying rate of MVD and HAD was 0.34-0.58 kg water kg dry solid À1 min À1 and 0.02-0.06 kg water kg dry solid À1 min À1 , respectively. An increase in drying rate by either increasing hot air temperature or increasing microwave power decreased the degree of crystallinity from 21.95% to 2.31% and from 7.72% to 4.05%, respectively. Moreover, the in… Show more

“…According to the Food and Agriculture Organization data [FAO, 2018], the worldwide pear production in 2014 was estimated at approximately 25.8 million tons. Fully mature pears play an important role in the human diet and nutrition as sources of dietary fi ber, vitamins C and B 6 , and minerals such as magnesium and potassium [Lutovska et al, 2016]. They are eaten in both the natural and processed forms as purees, jams, and dried pears [Santos, et al, 2014].…”

“…Ahmed et al. (2020) with samples of green banana flour, and Zhu, Guo, Wu, and Wang (2012) with samples of chestnut flour, determined their dielectric properties, which are important parameters in the design of a microwave oven; Bai‐Ngew, Therdthai, Dhamvithee, and Zhou (2015) studied the microwave vacuum drying and hot‐air drying on the physicochemical properties of durian flour comparatively. Therefore, the effect of those three drying methods on macro and micronutrients (β‐carotene and lycopene) in the produced flours was evaluated in this work.…”
