Study on the influence of water content to texture of dried areca nuts

The evaluation of the texture parameters for dried areca nuts during different water content by using texture profile analysis with the texture analyzer.The results showed that hardness, springiness and chewiness of dried areca nuts decreased significantly after the treatment, conversely, the adhesiveness increased significantly and the changed was insignificant after treated for more than 18%.The correlation analysis indicated the textural characteristics of dried areca nuts, including hardness, springiness, chewiness, and adhesiveness could well reflect the changes in texture of dried areca nuts.The above results provided theoretical basis for the quality control of dried areca nuts during processing.Therefore, the model was established for the evaluation of textural properties of dry betel nut, based on the consistent and up to 18% moisture content that combines the hardness, adhesion, elasticity, chewiness of dry betel nut determined by texture analyzer and sensory evaluation.
