With chayote as raw material,and glucose,jelly powder and citric acid as assistant material,the optimum processing technology and material formula was studied to develop chayote health jelly without any preservative and colorant.The final product was analyzed by sensory,chemical and microbiological inspection.Results showed that the optimum processing technology was that,choose glucose as sweet agent,the chayote juice temperature when adding jelly powder was 50℃,the continual boiling time was 1min,citric acid was added when pressing juice;the optimum material formula was that chayote juice 53.4%,water 30.5%,glucose 15.2%,citric acid 0.1%,jelly powder 0.8%.The above method could produce chayote health jelly with reseda,homogeneous and exquisite organization,delicious taste and good elasticity,rich nutrition and high edible safety.
