Effects of extrusion conditions on the physical and functional properties of instant cereal beverage powders admixed with mulberry (Morus alba L.) leaves Thai Agricultural
Chulaluck Charunuch; Plernchai Tangkanakul; Nipat Limsangouan; Vayhu Sonted.
On account of studying the feasibility of the production instant cereal beverage powders admixed with mulberry leaves by extrusion process, a box-behnken design of the response surface methodology (RSM) was employed to investigate the interaction of operating conditions at varying screw speed (300, 350 and 400 rpm), mulberry content (5, 10 and 15%) and feed moisture (15, 17 and 19%) on the physical and antioxidant property of product. Data were modelled by multiple regression analysis and the coefficient indicating for best fit model. The results showed that the effect of mulberry content and feed moisture had significant on bulk density, color, viscosity, water absorption index, antioxidant activity and total phenolic compound. Increasing of mulberry...

Iron fortification in developing of extruded Thai rice snack Thai Agricultural
Chulaluck Charunuch; Saowaluk Rungchang; Chowladda Teangpook; Vayuh Sonted.
To produce an acceptable snack of high nutritional quality for the programs against anemia and malnutrition, the direct expansion snack products were developed from extrusion process using Thai brown rice of two specialty hybridization (variety: 313 and 1000) as basic raw materials. For each variety of brown rice, the optimum operating conditions were investigated with twin-screw extruder at varying screw speed (300 and 350 rpm), type of iron fortificants (ferrous sulphate, ferrous lactate and ferrous fumarate) and level of iron content in snack product (20 and 100% RDI) in the 2×3×2 factorial experiment. Similarly, the optimum operating condition of snack production from each variety of rice had shown that increasing screw speed resulting in extrudate...

Functional properties of cereal and legume based extruded snack foods fortified with by-products from herbs and vegetables Thai Agricultural
Nipat Limsangouan; Makiko Takenaka; Itaru Sotome; Kazuko Nanayama; Chulaluck Charunuch; Seiichiro Isobe.
This study demonstrated the effect of extrusion processing on the functional properties of extruded snack foods developed from cereal and legumes, and the by-products from herbs and vegetables. The functional properties considered were antioxidant capacity, total phenolic compounds and resistant starch content. The results showed that Japanese green tea had the highest antioxidant capacity and phenolic content (68.31mmol Trolox/g and 337.58 mg GAE/g, respectively) and egoma leaves had the second highest (8.35 mmol Trolox/g and 60.60 mg GAE/g, respectively). Red kidney beans had the highest resistant starch content (33.78 % w/w) and corn grits had the second highest content (13.67% w/w). The extrusion process slightly decreased the antioxidant capacity...

การศึกษาคุณสมบัติทางกายภาพและเคมีของแป้งข้าวโพดบดหยาบดัดแปรด้วยกระบวนการเอกซ์ทรูชัน Thai Agricultural

Effect of particle size, feed moisture content and screw speed with different levels (250, 500 and 600 μm; 14, 16 and 18%; 300, 350 and 400 rpm) using a co-rotating twin screw extruder on physical and chemical properties (color, expansion ratio, bulk density, water absorption index (WAI), water solubility index (WSI), rheological and amylose/amylopectin content) of modified extruded products was investigated. Increasing feed moisture content results in extrudates with a higher bulk density, WAI and cold paste viscosity, but reduced the expansion ratio and WSI. Increasing particle size caused with a brighter color and higher amylose content. In case of higher screw speed increased the expansion ratio, WSI and amylopectin content.
