The study was conducted to investigate the effects of blanching regimes at the salt concentration and drying temperature using Sasaki heat pump drying technology on the quality of dried bamboo shoots to create a product that can be kept color, flavour, and quality. Fresh bamboo shoots were cut into slices with a thickness of 6 mm, boiled in hot saltwater at 100oC at different concentrations (0, 1, 3, 5%) for 15 minutes. Then, they were dried in the temperature setting differences (30, 40, 50oC) by Sasaki dryers and tested for moisture, color, cyanide content, microorganisms, water compensation capacity, and product sensory quality. Fresh bamboo shoots were boiled in hot saltwater at 100oC, 3% salt concentration for 15 minutes, and dried at 40oC by Sasaki drier for the best quality. This treatment mode provides the lowest color variation and the best water compensation compared to other treatment modes. Dried bamboo shoots are bright yellow, uniform color, characteristic odour, toughness with little deformation, low cyanide content, and microbiological content below the threshold of food hygiene and safety. |
