英文摘要:

      Objective To develop a nutritional and delicious leisure food of rose-flavor pumpkin seeds. Methods Pumpkin seeds were selected as the main raw material, white granulated sugar, citric acid, anthocyanins and rose flavor as the excipients. Taking the sense quality of the pumpkin seeds as the evaluation standard, a single factor and orthogonal experiment was conducted to obtain the best preparation ratio of the component. Results The best processing technology conditions were obtained as follows: white granulated sugar of 4%, citric acid of 0.2%, rose essence of 0.8% and the best ratio of essence to anthocyanins was 1:4, and the pumpkin seeds were baked at 100 ℃ for 6 h after decoated and then fried at 160 ℃ for 300 s. Conclusion The above experience provides a scientific basis for the development of the rose-flavor pumpkin seeds.
