Canistel seeds are part of the residues of Canistel fruit which can be used as functional foods, such as flour to be processed into various foods. This research was aimed at determining the physicochemical properties of canistel seed flour. Canistel seed was made into flour with two treatments; they were Blanched Canistel Seed Flour (BCSF) (at 80oC for 10 minutes)and Unblanched Canistel Seed Flour (UCSF). The flour process involves sorting, washing, treatment, stripping the shell and epidermis, washing again, drying, flaking and sieving.Physical analysis carried out included yield (by difference method), white degree of spectrophotometric reflectance method (Chromatometer), starch gelatinization profile using Rapid Visco Analyzer (RVA), the morphology of starch granules using polarization microscopy and Scanning Electron Microscope (SEM). Chemical analysis conducted on the BCSF and UCSF samples included proximate,amylose, amylopectin and starch content. Blanching at 80°C for 10 minutes had a significant effect on the physical properties of Canistel seed flour;yields were higher (41.6%) and chromatometric (colour) levels were lower (80.61). Pasting properties profile showed that UCSF had higher peak viscosity, breakdown viscosity but lower setback viscosity compared with the BCSF.Scanning Electron Microscope (SEM)and polarized light microscope showed starch granule structure changed due to the blanching. The appearance of starch granules on UCSF shows a tight starch granule. The appearance of starch granules on BCSF shows blanching treatment has changed the shape of the starch granules to be broken or damaged. The unblanched canistel seed flour (UCSF)showed that the starch granule still had birefringence appearance. This shows that the granule structures of the UCSF remained undamaged. Observation of the morphology of starch granules using polarization microscopy on BCSFshowed the starch granule was not visible and there was no appearance of birefringence. The loss of birefringence indicates that the starch granules had been damaged due to heating or hydrolysis. Chemical analyses on the samples showed significantly higher amylose content (24.79) but lower amylopectin content (31.39) in BCSF than UCSF.Starch, fat and carbohydrates contents were not significantly different (p>0.05) between BCSF and UCSF.Ash and protein content were significantly higher (p>0.05) in UCSF compared to the BCSF. Blanching of canistel seed flour reduces the swelling power of starch granules, increases retrogradation, accelerates thickening, decreases nutrition content, and changes microstructure of Canistel seed flour

AbstractIndigenous folk rice cultivars often possess remarkable but unrevealed potential in terms of nutritional attributes and biotic stress tolerance. The unique cooking qualities and blissful aroma of many of these landraces make it an attractive low-cost alternative to high priced Basmati rice. Sub-Himalayan Terai region is bestowed with great agrobiodiversity in traditional heirloom rice cultivars. In the present study, ninety-nine folk rice cultivars from these regions were collected, purified and characterized for morphological and yield traits. Based on traditional importance and presence of aroma, thirty-five genotypes were selected and analyzed for genetic diversity using micro-satellite marker system. The genotypes were found to be genetically distinct and of high nutritive value. The resistant starch content, amylose content, glycemic index and antioxidant potential of these genotypes represented wide variability and ‘Kataribhog’, ‘Sadanunia’, ‘Chakhao’ etc. were identified as promising genotypes in terms of different nutritional attributes. These cultivars were screened further for resistance against blast disease in field trials and cultivars like ‘Sadanunia’, ‘T4M-3-5’, ‘Chakhao Sampark’ were found to be highly resistant to the blast disease whereas ‘Kalonunia’, ‘Gobindabhog’, ‘Konkanijoha’ were found to be highly susceptible. Principal Component analysis divided the genotypes in distinct groups for nutritional potential and blast tolerance. The resistant and susceptible genotypes were screened for the presence of the blast resistant pi genes and association analysis was performed with disease tolerance. Finally, a logistic model based on phenotypic traits for prediction of the blast susceptibility of the genotypes is proposed with more than 80% accuracy.

Vital gluten is often used in baking to supplement weak wheat flours and improve their baking quality. Even with the same recipe, variable final bread volumes are common, because the functionality differs between vital gluten samples also from the same manufacturer. To understand why, the protein composition of ten vital gluten samples was investigated as well as their performance in a microbaking test depending on the water content in the dough. The gluten content and composition as well the content of free thiols and disulfide bonds of the samples were similar and not related to the specific bread volumes obtained using two dough systems, one based on a baking mixture and one based on a weak wheat flour. Variations of water addition showed that an optimal specific volume of 1.74–2.38 mL/g (baking mixture) and 4.25–5.49 mL/g (weak wheat flour) was reached for each vital gluten sample depending on its specific water absorption capacity.

In this study, physical and chemical properties (dry matter, ash, moisture, protein, fat, fiber, carbohydrate, starch, amylose, and vitamin C) of sweet potato tuber and flour of Anggun 1 cultivar were evaluated at different conditions. During peeling, the tuber and flour were processed subjected to three different conditions, which were unpeeled tubers (C1), peeled tubers (C2), and skin of tuber only (C3). From the results, the highest (p < 0.05) dry matter was observed in C1 while higher contents of ash, moisture, and protein were found in C3. Regarding the fat and vitamin C content, no significant differences (p > 0.05) were found between each condition. The highest fiber, carbohydrate, and amylose content (p < 0.05) were found in C1. The C1 and C2 reflected significantly higher (p < 0.05) starch content. Overall, these results provide important information about the peeling effect on the physical and chemical properties of Anggun 1. The information could be used as adding value to healthy food in the Malaysian diet due to the nutritional value of sweet potato.

The parents of children with dyslexia often experience more parenting stress and depressive symptoms compared to other parents. Studies have shown that supporting and encouraging such parents help in reducing their frustrations, fear, anger, and low self-esteem towards their children. The purpose of this study was to identify and examine the different types of support needed by the parents of children with dyslexia and to explore the relationships between the required support with the parents’ marital status. Fifty questionnaires were distributed to the parents of children with dyslexia and analyzed. The findings showed that the type of support needed for parents of children with dyslexia could be grouped into social, peer-to-peer, financial, and government support. Furthermore, the analysis indicated that there were no significant differences between the social (p = 0.4014), peer-to-peer (p = 0.5020), and government (p = 0.7121) support with parents’ marital status. However, based on one-way ANOVA analysis, there was a significant difference found between the parents’ marital status and financial support (p = 0.0241). Accordingly, it is anticipated that the implication of this research could be used as a guide and a reference for supporting and encouraging parents of children with dyslexia and other learning disabilities.
