Problems solved by technology

At present, in response to the demand of the pumpkin market in four seasons, the existing technology usually processes fresh pumpkins into pumpkin sauce and pumpkin drinks, which causes a large loss of pumpkin nutrients during the production process
Therefore, existing researchers have prepared pumpkin sauces with different tastes by using the method of making sauce, but the singleness of pumpkin flavor in the process of making sauce has become one of the new problems to be solved in pumpkin processing
