Abstract

Recently, Nam Prik Num was processed by bottle sealed and sterilized to extent shelf life on sale as souvenirs. Nam Prik Num in bottle sealed product has a messy texture and water separation problem on the surface of the product which was unacceptable by consumers. The objective of this research was to improve the texture quality of Nam Prik Num in bottle sealed product by adding various stabilizers including carboxymethylcellulose (CMC), guar gum and xanthan gum at concentrations of 0.1% and 0.3% (w/w) and to analyze appearance quality, yield percentage, chemical compositions, and physicochemical characteristics of products. The result showed that Nam Prik Num in bottle sealed product using various types of stabilizers has a better appearance, texture, stability, and inseparable water on surface of the product. In addition, the product with 0.3% guar gum had lowest water release percentage compared to other treatments. However, the addition of all stabilizers had no affected on yield percentage, proximate compositions (the percentage of moisture, protein, ash, fat and fiber contents), lightness (L*), redness (a*), yellowness (b*) and total color difference (∆E*), pH values and water activity (aw). Therefore, the addition of 0.3% guar gum can improve the texture stability and reduce water separation on the surface in Nam Prik Num in bottle sealed product. It could be applied in commercial production of Nam Prik Num.
