    Bioactive Compounds and Nutrition of Thai Sauces in Retort Pouch and Physicochemical Properties Kinetics During Storage
    (Journal of Current Science and Technology, 2024-05-02) Kanokkan Weeragul; Naruemon Nantaragsa; Chanchana Siripanwattana; Thitima Gaowmanee; Naratip Poonnakasem
    The objectives of this study were to investigate the bioactive compounds, including carotenoids, flavonoids, total phenolics, antioxidant activity, and nutritional values of two ready-to-cook Thai sauces of stir-fry curry sauce (SCS) and spicy-sour sauce (SSS) in retort pouch and to investigate the kinetics of physicochemical properties, including lightness (L*), water activity, pH and total soluble solids, of the products during storage at 30°C and 55°C. The results showed that the temperature and time for sterilization of SCS (low acid foods) was 121°C for 43 minutes and SSS (acid foods) was 102°C for 31 minutes. The moisture content was between 57.9 and 63.2%. SCS had higher total fat, saturated fat, and calories because it contained soybean oil and chili paste, but SSS had higher sugar and sodium content than SCS. Trans fats and vitamin C were not detected in either product. SSS had a higher content of total phenols, carotenoids (especially capsanthin, zeaxanthin, and β-carotene) and antioxidants than SCS. The representation of the physicochemical properties of the products as a function of temperature and time resulted in a linear model (R2 = 0.7222 – 0.9772). L*, water activity, pH decreased, and TSS increased during the 90-day storage at both 30°C and 55°C. The change was more remarkable when stored at 55°C than 30°C.

The results showed that the temperature and time for sterilization of SCS (low acid foods) was 121¡C for 43 minutes and SSS (acid foods) was 102¡C for 31 minutes.

SCS had higher total fat, saturated fat, and calories because it contained soybean oil and chili paste, but SSS had higher sugar and sodium content than SCS.

    Purple Sweet Potato Soft Bun as a Value-adding of Local Agricultural Production
    (Research and Development Institute Suan Dusit University, 2023) Boonyaporn Chuamsompong; Chanchana Siripanwattana; B. Chuamsompong; School of Culinary Art, Suan Dusit University, Suphanburi Campus, Suphanburi, 72000, Thailand; email: boonyaporn_chu@dusit.ac.th
    The research was undertaken to study the appropriate substituting level of purple sweet potato (PSP) flour for bread flour in making soft buns. Soft buns with 0-50% PSP flour substituting for bread flour were prepared. Prepared soft buns were visually observed and tests were performed to determined pH, moisture, color, firmness and springiness. A hedonic test was conducted with 30 untrained panelists in order to select the suitable level of PSP flour substitution. The original soft bun and the suitable PSP flour substituted soft bun were compared regarding shelf-life and nutritional values. When PSP flour substitutions were increased from 0 to 50%, visual observation of prepared soft buns showed size decreasing, crust color changed from light golden brown to dark purplish brown, crumb color changed from off white to dark purplish brown, texture was firmer and springiness was lesser. The pH of the soft buns was 5.47 Ð 5.65, which were not significantly different. The moisture contents of the soft buns with 10-50% PSP flour substitution, 25.03-26.35%, were significantly different and slightly higher than 24.49% of the control sample (0% PSP flour substitution). The hedonic test showed that 30% PSP flour substituted soft bun had the highest score (8.16) on overall liking. Therefore, it was selected as an appropriate soft bun for further study. The shelf-life of the control and 30% PSP flour substituted soft buns strored in polyvinylidenechloride (PVDC) bags with oxygen absorber, resulted in 3 days at room temperature (25¡C) and 7 days at refrigerator temperature (4¡C). Soft bun at 30% PSP flour substitution had a noticeable increase in vitamin A (from 981.0 to 3105 µg), carotene (from 0.7 to 13.4 mg), vitamin E (from 5.5 to 11.9 mg) and potassium (from 520.4 to1093.4 mg) compared to original one. Commercial PSP soft bun production with 30% PSP flour substitution for bread flour could add value for the local agricultural produce. © 2023, Research and Development Institute Suan Dusit University.
