Method for production of chestnut spread

摘要

The present invention relates to a method of preparing a chestnut spread. The method comprises the steps of: (A) subjecting skinned chestnuts to a retort treatment; (B) cutting the retort-treated chestnuts to a diameter of 15-30 mm to produce chestnut dices; (C) mixing the chestnut dices and a sweet pumpkin puree and subjecting the mixture to a first heat treatment to produce a chestnut mixture; (D) while maintaining a temperature of the step (C), adding a low-sweetness sugar and sugar to the heat-treated chestnut mixture, subjecting the mixture to a second heat treatment, and mixing the mixture with an aqueous pectin solution; (E) concentrating the mixture produced in the step (D) to a sweetness of 50-65 brix; (F) subjecting the concentrated mixture to a first sterilization; and (G) filling the sterilized mixture in a container and sealing the same to perform a second sterilization. Although a high pH and a low sweetness are typically prone to microorganisms, the spread of the present invention, while having a high pH and a low sweetness, shows excellent preservability.
