Keragaman Mutu Pati Beberapa Varietas Jagung

Corn-based industry requires information on physicochemical properties and functional characteristics of starch. The Information is useful as an indication of each corn variety for its USAge. Corn starch characterization was done in the ICERI Laboratory of Food Processing and Chemistry Service, Maros, South Sulawesi. The starch was extracted using the wet method, and then the resulting starch was analyzed for its proximate composition, physicochemical and functional properties. The results showed that the characteristics of starch from all varieties, including moisture, ash, starch, and degree whiteness satisfied the SII (Indonesian Industrial Standard). From the eleven samples that were evaluated could be classified into three criteria, namely: low amylose content 3.98-6.87% (waxy), moderate amylose content 23.26-24.85% (Local Takalar, Anoman), slightly high amylose content 30.60-31.85% (Srikandi Putih, Srikandi kuning) and high amylose content 45.87-48.29% (Palakka, Krisna, Bisma, Lamuru). Starch components of amylose correlated with functional property and amylograf property, while the protein and fat each did not show meaningful correlation. The information obtained from this research is useful as a database of corn starch characteristic which is useful for the future corn processing and also as reference for further research

Health related quality of life among Iraqi immigrants settled in Malaysia

<p>Abstract</p> <p>Background</p> <p>Migrants everywhere face several demands for health and maintaining good health and quality of life could be challenging. Iraqis are the second largest refugee group that has sought refuge in the recent years, yet little is known about their health related quality of life (HRQOL). The study aims at assessing the HRQOL among Iraqis living in Malaysia.</p> <p>Methods</p> <p>A self-administered Arabic version of Sf-36 questionnaire was distributed among 300 Iraqi migrants in Malaysia. The questionnaire taps eight concepts of physical and mental health to assess the HRQOL. Univariate analysis was performed for group analysis (t test, ANOVA) and Multiple Linear Regression was used to control for confounding effects.</p> <p>Results</p> <p>Two hundred and fifty three participants ranging in age from 18 to 67 years (Mean = 33.6) returned the completed questionnaire. The majority was males (60.1%) and more than half of the respondents (59.5%) were married. Less than half (45.4%) and about a quarter (25.9%) reported bachelor degree and secondary school education respectively and the remaining 28.7% had either a master or a PhD degree.</p> <p>Univariate analysis showed that the HRQOL scores among male immigrants were found to be higher than those of females in physical function (80.0 vs. 73.5), general health (72.5 vs. 60.7) and bodily pain (87.9 vs. 72.5) subscales. The youngest age group had significantly higher physical function (79.32) and lower mental health scores (57.62).</p> <p>The mean score of physical component summary was higher than the mental component summary mean score (70.22 vs. 63.34).</p> <p>Stepwise multiple linear regression, revealed that gender was significantly associated with physical component summary (β = - 6.06, p = 0.007) and marital status was associated with mental component summary (β = 7.08, p = 0.003).</p> <p>Conclusions</p> <p>From the data it appears that Iraqi immigrants living in Malaysia have HRQOL scores that might be considered to indicate a relatively moderate HRQOL. The HRQOL is significantly affected by gender and marital status. Further studies are needed to explore determinants of HRQOL consequent to immigration. The findings could be worthy of further exploration.</p
