In this study, the aim was to establish a pre-treatment process to utilize citrus pomace (CP) as a high-value-added material. Frozen CP was thawed under various conditions, including at room temperature, using ultrasound, and immersion at 25℃ and 70℃, and samples from each thawing group were assigned to a non-washed (NW) or a washed (W) group. The samples in the W-CP groups were drained, and all samples were powdered after hot air drying. The samples in the NW-CP groups had a two-fold higher drying yield of CP powder, a significantly lower pH (4.20–4.26), and a higher soluble solids content (1.1–1.3°Brix) than the samples in the W-CP groups. Interestingly, the samples in the W-CP groups had significantly higher swelling capacity (8.18–8.53 mL/g), water absorption index (7.61–7.85 g/g), water holding capacity (8.92–10.30 g/g), and oil holding capacity (2.09–2.30 g/g) than samples in the NW-CP groups (p<0.05). Conversely, the thawing method only significantly affected the thawing rate of the CP, but it did not significantly affect the properties of the CP powder. The results of this study provide basic data for the industrialization and resource utilization of CP, and they suggest that various pre-treatment processes can influence CP standardization.
