The present study was conducted to assess the physico-chemical quality of bottled drinking water marketed in Zomba City, Malawi. Seven bottled water brands were analyzed for pH, EC, TDS, K, Na, Ca, Mg, NO3-, F-, Cl- and total water hardness using standard methods. The results of the analysis were compared with Malawi Standard (MS) 560 for natural mineral water, MS 699 for bottled water other than natural mineral water, and the World Health Organization (WHO) guidelines for drinking water. The results showed that EC, TDS, Cl-, NO3-, F-, K, Na, Ca, and Mg in all the bottled water brands complied with MS 560, MS 699, and WHO guidelines for drinking water. Further, four bottled water brands had their mean pH below the minimum MS 560 and MS 699 value of 6.5. Comparison of the analyzed water quality parameters with the reported label values showed considerable variation in both exaggeration and undervaluing. This study has also shown that all brands had low fluoride content as compared to recommended levels by MS 560 and MS 699. The paper suggests the need for strict monitoring to check bottled water quality compliance.","PeriodicalId":474417,"journal":{"name":"Malaysian Journal of Science Health & Technology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135887665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A good plan prior to retirement is associated with significantly higher life satisfaction after retirement, given that many people spend a significant portion of their lives after a lengthy employment period. Personal retirement planning, on the other hand, is up to the individual. To ensure a comfortable retirement, employees must make a deliberate decision to set aside some of their earnings. However, past studies on retirement planning show that workers in Malaysia have made little or no preparation for their retirement. They only realize the need for retirement preparation when their savings are not enough to cover post-retirement expenses. Therefore, the main purpose of this study is to investigate the effects of attitude towards retirement, goal clarity, social influence, and financial literacy on the preparedness and confidence of private sector employees in Malaysia. Aside from that, the study intends to compare employees' retirement preparedness and confidence by gender as well as age group. The data for this study was collected through the use of a questionnaire. This study used ordered probit regression to see the effect of the determinants on retirement preparedness and confidence. The results of the study showed that attitude towards retirement, goal clarity, social influence, and financial literacy have a significant positive effect on retirement preparedness and confidence. Apart from that, male employees are found to be more prepared and confident to retire compared to female employees. Finally, employees between the ages of 31 and 40 are the most prepared and confident in their ability to retire. The study's findings have important implications for the retiring population in order for them to plan ahead of time so that they can survive throughout their retirement phase.","PeriodicalId":474417,"journal":{"name":"Malaysian Journal of Science Health & Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135887666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rendang ingredients vary according to different countries and mainly consist of spices, coconut milk, and meat, either chicken or beef. Spices such as coriander, fennel, cumin, ginger, galangal, lemongrass, garlic, and onion used in rendang mostly contributed to its antioxidant properties. However, the beef rendang's antioxidant properties may be lost due to the long cooking period. This study aims to determine the effect of cooking time and temperature on the extraction yield and antioxidant properties of beef. Rendang samples prepared using lean beef and mixed with coconut milk and other spices were collected every hour up to five hours of cooking. The samples were subjected to methanol extraction for total phenolic content (TPC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay using Folin-Ciocalteu and DPPH solution, respectively. The data were analysed by one-way analysis of variance (ANOVA) followed by Tukey's test. Data for extraction yield showed that rendang samples cooked for one and two hours had significantly lesser yield (p<0.05) than those cooked for three to five hours. For TPC analysis, rendang that was cooked for three hours had the highest total phenolic content (8.018 ± 0.911 mg GAE/g) (p<0.05) compared to those that were cooked for one, two, four, and five hours (4.205±0.364, 2.368±0.127, 2.746±0.080, and 1.839±0.110 mg GAE/g). For the DPPH assay, one-hour beef rendang sample had the lowest EC50 (20.278±0.733 µg/ml) (p<0.05) followed by those cooked for two, three, four, and five hours (39.041±1.368, 40.143±4.502, 48.338±2.115, and 58.159±3.060 µg/ml), indicating a low EC50 value which exhibited high antioxidant power. It can be concluded that antioxidant properties were significantly lost due to prolonged heating with increasing cooking time.","PeriodicalId":474417,"journal":{"name":"Malaysian Journal of Science Health & Technology","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135887451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The peels constitute lignin, hemicellulose, and cellulose, also known as lignocellulosic biomass. Cassava peels must undergo a pre-treatment method to separate the lignocellulosic material effectively. This study aims to investigate the optimal chemical pre-treatment methods and optimal pre-treatment concentration to produce sugar from cassava peel. Cassava peels were pre-treated with sodium hydroxide, sulphuric acid, and methanol with a catalyst (organosolv). Then, enzymatic hydrolysis was performed using cellulase to hydrolyze cellulose to glucose. The glucose yield is quantified using Dinitrosalicylic Acid Assay and a portable blood glucometer. The results showed that pre-treatment using sodium hydroxide at a concentration of 0.05 M at 121°C for 15 minutes gave the highest glucose yield of 4.53±1.20 mg/ml. Glucose produced from 0.05 M sulphuric acid (H2SO4) and 0.2 M organosolv sodium methoxide (MeOH+NaOAc) were 3.55±0.68 mg/ml and 3.29±0.93 mg/ml, respectively. Statistical analysis showed that the effect of different pre-treatment methods and pre-treatment concentrations had a significant glucose yield (P<0.05). Similarly, there was a significant difference (P<0.05) in the glucose yield under different pre-treatment concentrations. Further study on mechanical-assisted chemical pre-treatment methods is recommended.","PeriodicalId":474417,"journal":{"name":"Malaysian Journal of Science Health & Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135826174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, meat is low in calcium, dietary fibre, and vitamin C. Consumers' increased awareness of the possible links between nutrition and health has recently led to major dietary changes toward healthier food options. Furthermore, rising meat prices, vegetarianism, concerns about animal suffering, and sustainability issues have driven market trends toward meat alternatives from plant sources. As such, mushrooms are regarded as one of the healthier ingredients due to their nutritive, bioactive, and therapeutic values. The fibrous structure mimics the texture of meat and possesses an umami flavour, which imparts a meaty taste to the food products. Globally, Asian countries generate the highest percentage of overall mushroom production. The application of mushrooms, however, is limited to the fruiting bodies rather than the stems, which also contain high dietary fibre content. The stems are often discarded as food waste due to their tough texture. Researchers have begun to use edible mushroom waste and their by-products, especially stems, to create value-added products in a variety of sectors, such as the food industry, owing to their nutritional values and contributions to the circular economy and environmental protection. Thus, the primary intent of this review is to discuss the potential of underutilised mushroom stems in meat products.","PeriodicalId":474417,"journal":{"name":"Malaysian Journal of Science Health & Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135887663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the progressive cultivation activity of oyster mushrooms in Malaysia and their high nutritional values, they were selected to be incorporated in keropok lekor formulations to replace a partial percentage of fish flesh. In this study, the determination of nutritional composition and physical as well as evaluation of sensory acceptability of oyster mushroom-containing keropok lekor were carried out. Three formulations of keropok lekor with different ratios of fish flesh to oyster mushroom were prepared as follows: control (100:0), sample A (75:25), and sample B (50:50). In terms of nutritional composition, the results found that the value of ash, moisture, and carbohydrate contents of keropok lekor with oyster mushroom substitutions were significantly higher (P<0.05) than control keropok lekor. However, the experimental keropok lekor (sample A and sample B) had significantly lower (P<0.05) protein and fat contents than the control sample. The highest value of hardness, springiness, cohesiveness, and chewiness of the control sample (100% fish flesh) was obtained in comparison to keropok lekor substituted with oyster mushroom. In the context of colour, the value of L* (whiteness) increased by substituting oyster mushrooms into keropok lekor formulations due to the light colour of the mushroom. The 9-point hedonic scale test indicated that consumers’ preferences for experimental keropok lekor (sample A and sample B) were significantly (P<0.05) higher scores as compared to the control sample in terms of texture, taste, and overall acceptance. In contrast, appearance, colour, and aroma attributes obtained lower scores. The findings also suggested that replacing fish flesh with oyster mushrooms in keropok lekor has great potential to be commercialized in the market and represented as a new variety of keropok lekor in the food industry.","PeriodicalId":474417,"journal":{"name":"Malaysian Journal of Science Health & Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135887662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sweet potato crop had been grown for its edible tubers, leaving behind the top parts of the plants, which led to abundant agricultural waste, around 10 tonnes per hectare. Early studies showed that haulm (unused tops of the plants consisting of stem, stalk, and leaf) from sweet potato plants are a potential source of nutritional contents, including bioactive materials and antioxidants. Suppose the haulms or other fruit and vegetable waste (FVW) are utilised as these nutrient sources benefit Malaysia in terms of consumption and economy, promoting agricultural sustainability. In this study, the sweet potato haulm undergoes slow-juicing, heat-treatment, and freeze-drying. This research focused on elucidating the physicochemical and anti-nutrients analysis of pasteurised and unpasteurised sweet potato haulm juice powder (SPHJP) (water activity, colour analysis, water solubility index, oxalic acid, and phytic acid) as a potentially edible product. Results significantly showed that pasteurised SPHJP had lower water activity (0.34 aw), lower anti-nutrients concentration (oxalic acid and phytic acid), and a higher water solubility index than the unpasteurised SPHJP (p<0.05). It is proven that heat treatment is crucial when utilizing green waste material, as it can reduce the availability of anti-nutrients and increase its potential as a replacement for other green vegetables. Further study must be conducted to convert this underutilised agricultural product into biofertilisers, bioplastics, biofuels, or nutraceutical products.","PeriodicalId":474417,"journal":{"name":"Malaysian Journal of Science Health & Technology","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135887686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
