In this research, the response surface methodology with a polynomial model was used to represent the experimental data of the combination of steaming, drying, and tempering process for extra-large cashew nuts. The desired values of pre-treatment conditions minimize the broken kernel percentage and maximize the shelling capacity to achieve cost effectiveness. In the this study, the steaming, drying, and tempering conditions were optimized for the minimization of the broken kernel percentage and the maximization of the shelling capacity of extra-large cashew nuts (bigger than 32 mm). The optimal conditions were steaming temperature at 100 ℃ for 38 min, then drying at 70 ℃ for 30 min, and finally tempering for 4 h. Under these conditions, the minimal broken kernel and maximal shelling capacity achieved were 2.45 ± 0.24% and 14.58 ± 0.35 kg/h, respectively.

优化特大腰果脱壳的蒸干调质预处理

本研究采用多项式模型的响应面方法来表示特大腰果蒸、干、调相结合的实验数据。预处理条件的理想值可最大限度地减少碎仁百分比并最大限度地提高脱壳能力以实现成本效益。在本研究中，优化了汽蒸、干燥和回火条件，以最大限度地减少碎仁率，并最大限度地提高特大腰果（大于 32 毫米）的脱壳能力。最佳条件为100 ℃蒸38 min，70 ℃烘干30 min，最后回火4 h。在这些条件下，达到的最小破碎仁和最大脱壳能力分别为 2.45 ± 0.24% 和 14.58 ± 0.35 kg/h，
