Process Design for Production of Green Curry Sauce and Pad Ped Sauce
Abstract:
Green curry sauce and spicy stir-fried sauce (Pad Ped sauce) are low-acid foods. For
this reason, commercial sterilization is needed if shelf-stable products are desired. This
study investigated a thermal process for production of green curry and Pad Ped sauces
and defined the factors that affected the shelf-life of the products. The work was divided
into 2 parts. The first part was concerned with a heat penetration study to establish a
scheduled process. The second part of the study investigated the change in the product
quality, in terms of color and flavor, during storage. The product color was quantified in
terms of the Hunter L, a, b and M values, while sensory evaluation was used to
evaluate the product flavor. The heat penetration results indicated that for the process of
118 C / 18 min in an overpressure water-spray retort, F0 of the green curry sauce was 6
min, while that of Pad Ped sauce was 4.5 min. This process caused the change in the
color of green curry sauce; however, during storage, the color of green curry and Pad
Ped sauces only slightly changed with storage time and no effect of the storage
temperatures (30 and 40 C) was observed. The sensory evaluation results during 8
week-storage of green curry sauce and Pad Ped sauce showed that as the storage time
increased the preference scores of all attributes including color, flavor and overall
acceptability only slightly changed. Therefore, the storage temperature of 30 and 40 C
had no effect on the quality of green curry sauce and Pad Ped sauce during 8-week
storage.
