The equilibrium moisture content (EMC) of raw cashew nuts (RCN) were determined using the standard static gravimetric method at 30 °C, 40 °C and 50 °C for relative humidity (RH) ranging from 43 to 90 %. The proximate composition analysis, peroxide value and iodine value of RCN were assessed at this equilibrium stage. The RCN kept under the humidity of 86 and 90 percentage at all studied temperatures developed mold growth within 24-48 h of time. The better storage condition assessed for raw cashew nut is 67 % of RH at 30 °C and the values obtained for EMC, proximate composition analysis, peroxide value and iodine value are within the same range as observed with harvested RCN. Highlights • Raw cashew nut storage condition identified • It was analysed with different temperature (30 (°)C, 40 (°)C and 50 (°)C) and relative humidity (43 %-90 %) • Better storage condition for raw cashew nut is in 67 % of RH at 30 (°)C • In this condition the EMC was 8.11 % as within the range of moisture in harvested RCN.
采用标准静态重量法，在30℃、40℃和50℃下，针对相对湿度（RH）范围为43%至90%的情况，测定了生腰果（RCN）的平衡水分含量（EMC）。在此平衡阶段，对RCN进行了近似成分分析、过氧化值和碘值评估。在所有研究温度下，处于86%和90%湿度环境中的RCN在24 - 48小时内出现了霉菌生长。评估得出的生腰果较好储存条件是在30℃、相对湿度为67%，此时获得的EMC、近似成分分析、过氧化值和碘值与收获的RCN所观察到的值处于相同范围内。要点：• 确定了生腰果的储存条件 • 对其在不同温度（30℃、40℃和50℃）和相对湿度（43% - 90%）下进行了分析 • 生腰果的较好储存条件是在30℃、相对湿度为67% • 在该条件下，EMC为8.11%，处于收获的RCN的水分范围内
