Generally, the sweeter purple passion fruit referred to as the granadilla is preferred for consumption as fresh fruit, while the yellow passion fruit is grown mainly to produce juice concentrate or single-strength juice, fruit preserves, and jams, and as a flavoring agent. Passion fruit peel was used to extract pectin to produce biofilm because of its gelling properties and chemical composition to avoid wastage in the juice industry. The objective of this study is to characterize the physical and chemical properties of the pectin-based biofilm. The films were prepared using a casting technique where pectin acts as biopolymer, starch as the base, and glycerol as the plasticizer. Calcium chloride and citric acid were used as cross-linking agents. The results of the solubility test showed that pectin-based biofilms made from passion fruit are more hydrophilic compared to starch, but there was no significant difference in moisture content between the control and film containing 5 and 7 w/v% of crosslinking agent added. The film formed with calcium chloride showed better physical and chemical properties in terms of thickness, solubility, and moisture content. The formulation based on starch and pectin mixture was less rigid and had better elasticity compared to the control film. Therefore, producing films from passion fruit is a new alternative by taking waste from the juice industry.","PeriodicalId":18160,"journal":{"name":"Malaysian applied biology","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138999508","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}

Therefore, the potential exploitation of photosynthetic bacteria (PSB) from aquaculture waste was investigated to treat the wastewater in the fish culture. In this study, the wastewater was collected from a fishpond and cultured in sunlight-exposed sterile bottles for 14 days. In the water additive experiment, five treatments (in a 30 cm3 aquarium) were prepared namely cultured PSB (T1), aquatic plant hornwort (T2), aquatic plant salvinia (T3), positive control (P), and negative control (N). Five individuals of Hyphessobrycon herbertaxelrodi (2.5±0.5 cm length) were placed in each treatment and reared for 30 days. Meanwhile, for the wastewater treatment, four treatments (in a 30 cm3 aquarium) were prepared namely wastewater from the hatchery fishpond (S1), wastewater from the hatchery fish tank (S2), positive control (P), and negative control (N). The results obtained indicate that T1 treatment significantly improved and maintained the water quality as compared to other treatments. The results showed the amount of ammonia and nitrite in S1 and S2 supplied with T1 for 30 days gradually decreased from day 1 until day 18. While zero amount of ammonia and nitrate was acquired from day 21 until day 30 of the wastewater experiment. The treatment with PSB showcased the bacteria's ability to utilize and absorb nutrients, thereby maintaining and improving water quality. The potential use of beneficial bacteria in the culture system can accelerate the nitrogen cycle for a sustainable way of wastewater management.","PeriodicalId":18160,"journal":{"name":"Malaysian applied biology","volume":"48 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138995977","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 use of carbofuran in Malaysia is to be banned effectively in May 2023. Limited data were published on the uptake and distribution of carbofuran and its metabolites for most crops. Therefore, a study was conducted to assess carbofuran residues in watermelon grown at the Agriculture Research Centre, Semongok. Carbofuran at 17 kg/ha and 34 kg/ha were applied to watermelon planted under the recommended agronomic practices. The plants were sampled at periodic intervals over 63 days after being treated with carbofuran. The carbofuran and their metabolites in the watermelon leaf, stem, and fruits were determined using a liquid chromatography equipped with a triple quadrupole mass spectrometer. The carbofuran residues were observed up to 35 days after application and reached below the quantification level (0.01 mg/kg) at 42 days after application. Residues were concentrated in the roots and stems for both treatments. About 80 to 90% of the carbofuran was metabolized to carbofuran-3-hydroxy in the watermelon leaves, and 50% in the stems. The highest residue level of carbofuran for application at 17 kg/ha was recorded on Day 9 for roots (0.192 mg/kg), Day 21 for leaves (0.057 mg/kg), and Day 5 for stems (0.134 mg/kg). At 34 kg/ha, the highest carbofuran residues concentrations were recorded on Day 5 for root (0.446 mg/kg) and stem (0.151 mg/kg), and Day 3 for leaves at 0.303 mg/kg. Traces of carbofuran residues were detected in the skin and flesh of the fruit. The carbofuran residue levels in watermelon fruit were below the established MRL of 0.01 mg/kg.

Beyond flavour, these plants also contribute essential antioxidants crucial for human health by inhibiting free radicals that can lead to various diseases. In Bintulu, Sarawak, Malaysia, locals traditionally consume indigenous flavouring plants primarily for their culinary impact, often overlooking the pharmaceutical value these plants may offer. This study aimed to assess the marketable appearance and antioxidant composition of indigenous food flavouring plants in Bintulu. Bunches of Pangium edule, Premna serratifolia, Pycnarrhena tumefacta, Scorodocarpus borneensis, and Syzygium polyanthum were obtained from the local farmers market and analyzed for morphological dimensions, total phenolic content, free radical scavenging ability (DPPH), and ferric reducing ability (FRAP). The edible portion of the plants ranged from 57.33% to 84.99%, with P. edule exhibiting the largest edible blade. Total phenolic content varied from 343.27 to 3245.67 mg GAE/100 g, with P. serratifolia having the highest value. Premna serratifolia demonstrated the strongest radical scavenging activity, while S. polyanthum exhibited the highest ferric reducing ability. All species exhibited high antioxidant composition (IC50 = 0.10 to 27.6 µg/mL, FRAP = 469.88 to 9272.50 mg TE/100 g), indicating potential medicinal utility. Further studies on anti-nutrients like oxalate and phytate are recommended to complement the obtained data.

The findings of this study are critical to scientifically identify and document food sources from the forest that contribute to the tribe's livelihood and, possibly, future food security. In the Bateq villages, information was gathered via semi-structured surveys, field trips, group discussions, and key informant interviews. The results show that TEK influenced the use of wild tubers inherited from their ancestors. The Bateq ate at least 11 different types of wild tubers, including Dioscorea orbiculata, Dioscorea prainiana, and Dioscorea hispida. Most of these wild tubers are from the Dioscoreaceae plant family and must be properly processed before being consumed. The elements related to the traditional knowledge of the wild tubers are the harvesting skills and the practice in the utilization of the plant. The survey also suggests that the selection to use plant tubers is prompted by its delicious taste and nutritional value while being natural and unpolluted food. In terms of plant sustainability, the majority of the Bateq will follow certain conservation techniques to maintain the plants' availability. Understanding what underlies TEK and the tribe's practices in using wild plant resources will preserve the natural legacy of forest resources and biodiversity, and possibly contribute to future food security.","PeriodicalId":18160,"journal":{"name":"Malaysian applied biology","volume":"20 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138970745","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 widely consumed EBN for its highly unique nutrients has contributed to a high demand for international exportation. However, the processing of EBN to remove inedible materials (i.e. sand, dust, feathers) has contributed to several wastes. The disposal of this waste is hazardous to the environment and a waste of value due to abundant sialylated-mucin (SiaMuc) glycoprotein attached in the impurities. This “waste” is the processing co-product of EBN. Therefore, this study aimed to recover SiaMuc-glycoprotein in EBN co-product (EBNco-P) in the form of bioactive SiaMuc-glycopeptide. Through enzymatic hydrolysis, an eco-friendly alternative to transform insoluble SiaMuc-glycoprotein in EBNco-P into soluble bioactive SiaMuc-glycopeptide, valuable nutrients are separable from the impurities. Previously, through our research, this biotechnology has been applied to cleaned EBN. The research finds that the enzymatic hydrolysis of EBN that produces EBN glycopeptide has led to bioconversion into a high-grade product with enhanced nutritional bioavailability and functionality. Similar results are also revealed in the analyses of cleaned-EBN and EBN co-products. Whereby, the result revealed that the optimum hydrolysis period was at 90 min, in which the DH and enhanced solubility indicated a complete breakdown of glycoprotein into bioactive glycopeptide. This result is in line with the physicochemical analysis result. The hydrolysis has significantly decreased (p≤0.05) the EBN protein content, while the levels for peptide, glycopeptide, polysaccharides, and sialic acid showed the opposite. This study may contribute to broadening the EBN product development in terms of nutraceutical functionality. With the availability of low-cost EBN co-products, this study is beneficial not only scientifically, but also to the consumers, commercialization, and industrialization.","PeriodicalId":18160,"journal":{"name":"Malaysian applied biology","volume":"1 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138999226","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}

There is limited information on food wrappers based on Sarawak’s natural resources. However, among the older Sarawak communities, such knowledge is present and valuable. Unfortunately, this information is on the verge of extinction due to a lack of documentary. Therefore, this study was conducted to identify and document the plant-based food wrappers used by the communities in Sarawak. An ethnobotanical study was conducted using face-to-face interviews with 384 respondents. The study was conducted in a semi-structured manner from December 2021 until May 2022. A total of 21 species of plants from 11 different families has been identified as food wrapper by the community in Bintulu, Sarawak. The community dominantly used leaves as food wrappers because they can be handled easily and enhance the aroma of the food. Some plant-based food wrapper gives a distinct flavor and aroma to the food when applied with heat. Plant-based food wrappers also had huge potential as more than 90% of respondents were satisfied with the usage and suggested that these wrappers be developed into ready-made form. Locals also informed that plant-based food wrappers can help to expand their economic profit, especially for sellers. Therefore, this study was able to discover the indigenous plant species utilized as traditional food wrappers that have been forgotten. However, further study about the nutritional composition, fiber structure, antibacterial ability, and volatile compound of the species can be conducted to provide a full record of the plants, especially as food aroma enhancers.","PeriodicalId":18160,"journal":{"name":"Malaysian applied biology","volume":"83 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138999593","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 objectives of the present study were to investigate the parasite prevalence in both zones, as well as to determine the effect of differing marine zones regarding the presence of parasites in fish. A total of 30 individual fish occurring in pelagic and benthic zones were randomly selected from three different fishmongers at a wet market in Bintulu, Sarawak. Both the gill and stomach content of the samples were examined to detect the presence of parasites. Nematodes and trematodes were observed in the intestinal tract of the fish, Cymothoa exigua was found attached to the fish tongue, and monogenean parasites were also detected on the gills. The prevalence of the parasite was roughly equal in Setipinna breviceps, Ilisha megaloptera, and Selaroides leptolepis. The highest prevalence of parasites (87.50%) from fish in the benthic zone based on fish size was for fish measuring between 20.1 - 30.00 cm in total length (P-value=0.3778), whereas for pelagic fish, the highest prevalence of parasites (100%) in fish measurements of 30.1 – 40.0 cm in total length (P-value=0.0044). A major factor for the diversity of marine fish parasites occurring in the different zones is the difference in feeding behavior of the hosts and depth distribution which resulted in low or high rates of parasite infestation.","PeriodicalId":18160,"journal":{"name":"Malaysian applied biology","volume":"14 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139001303","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}
