Effect of Drying Technique and Rice Variety to the Content of Antioxidant, Fiber, and Nutrient Composition of Rice Bran.

Effect of Drying Technique and Rice Variety to the Content of Antioxidant, Fiber, and Nutrient Composition of Rice Bran.

Results of analysis of variance also showed that the treatment of rice varieties and rice bran flour drying technique also significantly affect (p <0.05) the content of soluble dietary fiber (SDF). The average value of SDF in rice bran flour levels is presented in Figure 4. Combine treatment between rice bran flour from Cigeulis varieties and using microwaves dried technique has the highest SDF content or at 6.31%, while the lowest SDF content of 4.91% was obtained in the combine treatment between Cigeulis rice variety and oven drying technique. This is because of pectin degradation due to the use of high temperatures in the oven drying technique. This statement is in accordance with the results reported by Nyman in 2003 for commodities such as: carrots, green beans, and mungbean that cooked by blanching technique has a lower content of SDF compared to cooking using a microwave oven and similar results in previous studies by Svanberg et al. (1997) for mungbean. Results of analysis of variance also showed that the interaction between rice varieties and drying technique significantly (p <0.05) affect the content of dietary fiber (TDF) of rice bran flour. Average TDF content of rice bran flour from rice varieties and drying technique is presented in Figure 5. Combine treatment of Cigeulis variety and microwaves drying technique has the highest TDF content of rice bran flour or at 36.82%, while the combine treatment between Ciherang rice variety and ordinary oven drying technique showed the lowest TDF contains in rice bran flour or at about 17.19%.

Production by Lintnerization-Autoclaving and Physicochemical Characterization of Resistant Starch III from Sago Palm ( Metroxylon sagu rottb) | Pratiwi | Indonesian Journal of Chemistry 21199 40284 1 PB

Native sago starch had the highest protein and fat than others. Hydrolysis by citric acid decreased significantly protein and fat contents. Also after autoclaving-cooling treatment, protein and lipid content decreased, because heat treatment can denature protein and saponify fat which became soluble. Crude fiber content of lintnerized-autoclaved starch was highest than native and lintnerized starch. It was related with re-associate the structure when gelatinization and retrogradation process. Moisture content of most native starches was around 12% at ambient temperature and humidity conditions. Lintnerized-autoclaved starch had the lowest moisture (8.33 ± 0.1).

Development and mechanical testing of wood composite (WPC) made recycled polymer and recycled wood flour.

Development and mechanical testing of wood composite (WPC) made recycled polymer and recycled wood flour.

The equilibrium moisture content of wood is affected by temperature and humidity and can vary as much as 3-4% depending on if the higher or lower humidity (i.e. wood exhibits a moisture sorption hysteresis). The moisture sorption of fillers and reinforcements derived from wood are affected by the methods used to produce them. However, wood flour is produced mechanically and its moisture sorption properties are similar to that of solid wood. Wood flour usually contains at least 4% moisture when delivered, which must be removed before or during the processing with thermoplastics. Even if dried, wood flour can still absorb moisture quickly. Depending on ambient conditions, wood flour can absorb several percent of moisture within hours. Moisture of up to about 30% can be adsorbed by the cell wall with a corresponding reversible increase in an apparent wood volume. Volume changes of the wood component due to moisture sorption, especially repeated moisture cycling, can lead to interfacial damage and matrix cracking (Peyer and Wolcott, 2000). As a result, many manufacturers of WPCs limits wood flour content to 50-65% by weight in the composite formulation and rely on the partial encapsulation of the wood by the polymer matrix to prevent major moisture sorption and subsequent negative effects to the fabricated composite.

A Study on the Mechanical and Forming Performance of Oil Palm Fiber Reinforced Polypropylene Composite.

A Study on the Mechanical and Forming Performance of Oil Palm Fiber Reinforced Polypropylene Composite.

When the average experimental spring-back was compared with the empirical result, the trend is quite similar to each other as shown in Fig. 6. For run 45 and run 46, we can see that the spring-back increases from 1.25° to 24°. This was due to the difference in temperature. As explained previously, temperature plays a huge role in the spring-back angle of the oil palm fiber composite. At run 45, the temperature was 150°C while at run 46 the temperature was 130°C. This attribute can be seen for all of the samples pre- heated at 150°C and 130°C. Based on the empirical equation, the expected spring-back angle for the parameter of temperature 150°C, fiber composition 30wt%, feed rate of 500mm/min and tool radius of 2mm is -1.29° while experimentally it was -1.75°.
