Abstract
The preprocessing stage is crucial in vegetable processing, significantly influencing the final product's quality. This study investigates the effects of various pre-pre-treatment methods, including cutting, blanching, osmotic, and ultrasound-assisted osmotic treatment, on the quality characteristics, water migration, and microstructure of white radish. The results showed that osmosis and ultrasound-assisted osmosis has the least effect on the total color difference (ΔE) and the greatest water loss (WL) ( p < 0.05); blanching has the least effect on the hardness and eutectic points ( p < 0.05); and the blanching-ultrasound-assisted osmosis has the greatest solid gain ( p < 0.05). The increase of WL led to a decrease in hardness (−0.82). By analyzing the quality characteristics of different pre-treatment methods, contributing to the development of suitable pre-treatment methods for different products and optimization pre-treatments according to requirements. The mechanism of quality characteristics of pre-treatments on products is the future research direction. • Osmosis and ultrasound-assisted osmosis minimize color change in white radish. • There is a negative correlation between water loss and hardness. • Blanching-ultrasound-assisted osmosis maximizes solid gain in white radish. • Study aids in optimizing pre-treatment methods for vegetable products.
