The optimization of temperature, immersion time and coating treatment, during hot air drying of honeydew, was investigated by the response surface methodology. The results show that the coated sample with immersion time of 35 min at drying temperature 55 °C was determined as the optimum condition for this study. The honeydew was coated with pectin-CMC-based edible coating (except non-coated sample) and was then hot-air dried. The data from the chromameter for colour analysis showed that the decreasing value of ΔE as the immersion time and temperature increase and non-coated samples also shows higher value than coated samples. The results of the texture (skin strength) analysis showed that the longer immersion time resulted in lower skin strength. However, the coated samples had better structural integrity and higher moisture content, but the plasticizing effect from the coating result in the lower skin strength. Highest moisture content recorded was from coated sample with 60 min immersion time at 58 °C. Pectin-CMC-based edible coating acts as a barrier where the sample moisture was trapped; longer the immersion time and higher barrier produced. Coated sample showed lower rehydration ratio than non-coated sample. The pectin-CMC-based edible coating solutions produced a sticky layer on the surface of samples, which is solidified during air-drying and this layer can potentially reduce water absorption into the porous structure in honeydew texture.

Production of the deep-fried cassava chips has contributed to high cooking oil waste production. The frying process could increases the lipid content and reduce the physical attributes of the chips. This research aimed to evaluate the effect of carboxymethyl cellulose (CMC) concentration (1, 2 and 3%) on the coated-fried cassava chips characteristics. A dipping-coating method was used and the characteristics evaluated were lipids content, colour measurement, texture, functional group and sensory analysis. All data were analysed using one-way ANOVA and Duncan multiple range test. Result showed 3% CMC could reduce the lipid content of chips up to 10%. Besides, the coated chips produced a better crispiness level as compared to uncoated chips. The colours were darker in the higher concentrations of CMC coated chips. FTIR spectra confirmed the presence of CMC coating on the coated sample. The coated chips showed a slightly higher sensory overall acceptability. Overall, the CMC-coated cassava chips reduced the lipid contents and improved physical properties of the snack.

Rice husk has become global concern due to the environmental problem since it has been dumped and open burned that contributed to the emissions of carbon dioxide to the atmosphere. Therefore, utilization of rice husk to other useable product such as silica aerogel for adsorption has been study recently due to the silica content in rice husk is about 60% and this material is sustainable and cost effective. Silica aerogel was prepared from rice husk ash and dried by using ambient pressure drying method with addition of tetraethyl orthosilicate (TEOS) due to its capability to prevent the gel from crack and increase the porosity of gel to increase the capacity of adsorption process. The silica aerogel was further characterized by using Fourier Transform Infrared spectroscopy (FTIR), Elemental Anaylzer (EA) and Scanning Electron Microscopic (SEM). The results show that the silica aerogel was successfully synthesized using rice husk ash. The FTIR studies reveal that silica aerogel produced consist of amorphous silica with Si-O-Si bonding and stretching's. From EA analysis, the carbon in the rice husk decreasing when turn into silica aerogel due to the burning of carbon content in the preparation of silica. The SEM studies confirm that the silica aerogel has a porous structure and has ability to for the application adsorption process such as carbon dioxide adsorption, methylene blue adsorption and others application.

ABSTRACTUnderlying mechanisms by which exposures to toxic metals/metalloids impact obesity and type 2 diabetes (T2DM) risk remain largely unknown. Gut microbiota have been strongly associated with cardiometabolic risk. To assess relationships between high metal exposures, gut dysbiosis, and metabolic dysregulation, we analyzed associations among gut microbiome taxa, dichotomized metal levels (arsenic, lead, mercury, cadmium), clinical measures (BMI, fasting blood glucose, blood pressure), and diagnoses (hypertension, obesity, diabetes) in 178 African-origin adults (52% female, mean age = 43.0 ± 6.4 years) from Ghana, South Africa, Jamaica, Seychelles, and USA. High vs. low lead and arsenic levels had a significant effect on beta diversity (p< 0.05). Seventy-one taxa were associated with high lead levels: 30 with elevated BMI, 22 with T2DM, and 23 with elevated fasting blood glucose (p< 0.05); 115 taxa were associated with high arsenic levels: 32 with elevated BMI, 33 with T2DM, and 26 with elevated blood glucose (p< 0.05). Porphyrin metabolism was the most enriched metabolic pathway in taxa associated with higher lead and arsenic exposure. These data provide the first findings from African-origin adults that demonstrate the association between the gut microbiome with lead and arsenic exposure and obesity and T2DM risk.

Cartilage has poor regenerative capacity and thus damage to the joint surfaces presents a major clinical challenge. Recent research has focussed on the development of tissue-engineered and cell-based approaches for the treatment of cartilage and osteochondral injuries, with current clinically available cell-based approaches including autologous chondrocyte implantation and matrix-assisted autologous chondrocyte implantation. However, these approaches have significant disadvantages due to the requirement for a two-stage surgical procedure and an in vitro chondrocyte expansion phase which increases logistical challenges, hospital times and costs. In this study, we hypothesized that seeding biomimetic tri-layered scaffolds, with proven regenerative potential, with chondrocyte/infrapatellar fat pad stromal cell co-cultures would improve their regenerative capacity compared to scaffolds implanted cell-free. Rapid cell isolation techniques, without the requirement for long term in vitro culture, were utilised to achieve co-cultures of chondrocytes and stromal cells and thus overcome the limitations of existing cell-based techniques. Cell-free and cell-seeded scaffolds were implanted in osteochondral defects, created within the femoral condyle and trochlear ridge, in a translational large animal goat model. While analysis showed trends towards delayed subchondral bone healing in the cell-seeded scaffold group, by the 12 month timepoint the cell-free and cell-seeded groups yield cartilage and bone tissue with comparable quality and quantity. The results of the study reinforce the potential of the biomimetic tri-layered scaffold to repair joint defects but failed to demonstrate a clear benefit from the addition of the CC/FPMSC co-culture to this scaffold. Taking into consideration the additional cost and complexity associated with the cell-seeded scaffold approach, this study demonstrates that the treatment of osteochondral defects using cell-free tri-layered scaffolds may r

The textile industry is known to use massive amount of dyes to colour fabrics and subsequently the treatment of textile effluent is one of the greatest challenge. The aim of this research is to investigate the ability of the bacterialfungal consortium to decolourise methyl red dye. The synergy effects of microbial consortium offer considerable advantages over single culture in mineralisation of complex dye compounds. The consortia were developed by using isolated white rot fungi and strain of Bacillus subtilis. The sample of white rot fungi were isolated from rotten wood and then were observed under microscope to determine its morphology. The individual cultures of white rot fungi designated as WRF D1, WRF E1, WRF F1, WRF G1 and WRF H1 and Bacillus subtilis were tested on the ability of decolourising 50 mg/L of methyl red. The results of the study were compared with the performance of microbial consortium of white rot fungi and Bacillus subtilis. Based on the observation, the strain of isolated fungi exhibited similar morphological characteristics of white rot fungi with the filamentous shape and the presence of basidiospores. The preliminary study demonstrated the ability of the isolated white rot fungi to produce ligninolytic enzyme by formation of brown ring on PDA plate containing MnCl2. The decolourisation of methyl red by the individual cultures was in the range of 35 - 40 %. The result revealed that consortium of white rot fungi and Bacillus subtilis significantly enhanced the decolourisation of methyl red dye with more than 80 % of dye removal. The highest percentage of decolourisation (82.16 %) was exhibited by the consortium of WRF E1 and Bacillus subtilis after 72 h in shaking conditions (120 rpm, 30°C and pH 5). The data collected from this research provided convincing evidence on the potential of bacterial-fungal consortium for dye decolourisation. Copyright © 2017, AIDIC Servizi S.r.l..
