Syneresis is one of the common textural quality defects found in traditionally prepared buffalo milk curd (meekiri). The current study aimed to determine the effect of incorporating Lacticaseibacillus rhamnosus GG (LGG) and arrowroot (AR) powder alone and in combination on the physicochemical properties of buffalo milk curd over refrigerated storage. Four buffalo milk curd formulations were prepared: control curd (without probiotic and prebiotic), probiotic curd (with 2% LGG), prebiotic curd (with 3% AR powder), and synbiotic curd (with both 2% LGG and 3% AR powder). The syneresis, pH, titratable acidity, and textural properties (hardness, cohesiveness, gumminess, and adhesiveness) were evaluated over the refrigerated storage at d 1, 4, 7, and 10. The addition of LGG resulted in decreased syneresis and acidity, and increased hardness, gumminess, and chewiness. In contrast, AR positively affected decreased syneresis and acidity. LGG and AR powder in combination significantly lowered syneresis however negatively affected on the hardness, gumminess, and chewiness.
在传统制备的水牛奶凝乳（meekiri）中，粘滞是常见的质构质量缺陷之一。本研究旨在确定单独或混合添加鼠李糖乳杆菌 GG（LGG）和箭根粉（AR）对水牛奶凝乳在冷藏储存期间的理化特性的影响。制备了四种水牛奶凝乳配方：对照凝乳（不含益生菌和益生元）、益生菌凝乳（含 2% 的 LGG）、益生元凝乳（含 3% 的 AR 粉）和合成益生菌凝乳（含 2% 的 LGG 和 3% 的 AR 粉）。在第 1、4、7 和 10 天的冷藏贮存期间，对凝乳的收缩性、pH 值、可滴定酸度和质地特性（硬度、粘合性、胶粘性和粘附性）进行了评估。添加 LGG 后，淀粉粘合性和酸度降低，硬度、胶粘性和咀嚼性增加。与此相反，AR 对减少粘结性和酸度有积极影响。将 LGG 和 AR 粉混合使用可显著降低粘滞性，但对硬度、胶粘性和咀嚼性有负面影响。

Misconceptions and their influence on chicken egg consumption pattern, buying behaviour, and attitudes among the urban and rural communities in Western province of Sri Lanka were investigated. A total of 690 respondents representing Colombo, Gampaha, and Kalutara districts were interviewed using a pre-tested questionnaire. Chi-square analysis and the descriptive statistics were used to analyze the data. According to the results, 67.1% of respondents believed that the village chicken eggs are more nutritious than the commercial chicken eggs. The majority (95.4%) did not accept the fact that the brown eggs are nutritionally sound than the white shelled eggs. Of the total respondents, 46.2% trusted that the daily consumption of chicken eggs can lead to hypercholesterolemia and increases the risk of cardiac disorders. Information derived from the general public and social media were identified as the main sources of the misconceptions discussed. In conclusion, of all misconceptions tested two misconceptions: (1) the eggs from village chicken are nutritious than the commercial chicken eggs and (2) the chicken eggs when consumed daily can increase the risk of cardiac disorders, do exists. The study further concluded that the majority of the participants are willing to change their attitudes if it is guaranteed that both the village and commercial chicken eggs are coequally nutritious, and both white and brown eggs are safe to eat daily, infertile, and coequally nutritious.

The occurrence of accidental fires in sugarcane plantations is a significant cause of pre-harvest loss in the sugar industry, particularly during arid seasons. This paper introduces the conceptualization and implementation of a microcontroller-based prototype system for mitigating accidental fires in sugar cane plantations. The proposed system encompasses two distinct subsystems: the field monitoring and the fire control unit. The Field monitoring system, deployed within the sugarcane field, assumes responsibility for fire detection via smoke detectors, infrared detectors, as well as carbon dioxide and carbon monoxide detectors, which are accompanied by a fire extinguishing mechanism. Conversely, the fire control unit, installed at the fire brigade office, establishes wireless communication with the field monitoring system through the global system for mobile communication (GSM) network. Upon detecting a fire, the microcontroller promptly dispatches a fire alert to the fire brigade while simultaneously activating water pumps to suppress the fire until the brigade arrives to fully extinguish it. Furthermore, the fire control unit triggers the fire alarm and exhibits the global positioning system (GPS) coordinates of the burning field to facilitate precise localization. The proposed system uses the Arduino-Mega and Arduino- Leonardo microcontroller platforms and is programmed using the C++ programming language in Visual-Studio-Code software and the Arduino integrated development environment. Designed prototype can detect fires and alert the fire brigade in less than twenty seconds and activate water pumps in less than one second after fire detection.

Sri Lankan black tea is renowned for its high quality and regarded as a brand that is chemically safe, ozone-friendly, and ethically acceptable with accountable stakeholders in the supply chain. Meantime, food safety has become one of the mandated food attributes that is heavily concern by stakeholders even at the estate level. Hence, this study aimed to determine the level of knowledge, attitudes, and practice (KAP) of managers at black tea manufacturing in the Uva region of Sri Lanka regarding basic food safety concerns. Data were collected from 30 respondents at 30 black tea manufacturing factories in the Uva region using a stratified random sampling technique. A pre-tested interviewer-administered questionnaire based on KAP of basic food safety was utilized and collected data were analyzed using descriptive analysis and correlation analysis. The study indicated that the mean percentage of knowledge was satisfactory (93.1%), and the mean score for attitudes and practices of food safety was 4.7±0.4 (X±SD) and 4.6±0.5 (X±SD), respectively. However, this study depicted that the knowledge of food safety influenced managers’ attitudes (0.421, P<0.05) but not their food safety behaviour. Further, they believed that food safety management systems would be a means of directing their black tea to the international market (76.7%), while pledging the concerns of food safety (70%). However, it was depicted that constraints with food handlers (100%) and financial difficulties (73.3%) hugely affected the implementation of food safety management systems at the black tea manufacturing factories in the Uva region of Sri Lanka. Hence, this study suggests continuous, periodical but short training to sustain the practice of handling teas safely in the Uva region of Sri Lanka.
斯里兰卡红茶以其高品质而闻名，被认为是化学安全、臭氧友好型品牌，并在供应链中得到负责任的利益相关者的道德认可。与此同时，食品安全已成为利益相关者（甚至在庄园层面）高度关注的法定食品属性之一。因此，本研究旨在确定斯里兰卡乌瓦地区红茶生产企业管理人员对基本食品安全问题的认知、态度和实践（KAP）水平。研究采用分层随机抽样技术，从乌瓦地区 30 家红茶制造厂的 30 名受访者中收集数据。采用了预先测试过的访谈者发放的基于基本食品安全 KAP 的调查问卷，并使用描述性分析和相关性分析对收集到的数据进行了分析。研究表明，食品安全知识的平均百分比令人满意（93.1%），食品安全态度和实践的平均得分分别为 4.7±0.4（X±SD）和 4.6±0.5（X±SD）。然而，本研究表明，食品安全知识影响管理人员的态度（0.421，P<0.05），但不影响他们的食品安全行为。此外，他们认为食品安全管理系统是将红茶推向国际市场的一种手段（76.7%），同时承诺关注食品安全（70%）。然而，研究结果表明，食品处理人员（100%）和财政困难（73.3%）极大地影响了斯里兰卡乌瓦地区红茶制造厂食品安全管理系统的实施。因此，本研究建议在斯里兰卡乌瓦地区开展持续、定期但短期的培训，以维持安全处理茶叶的做法。

Reusing waste through various activities and efficient and effective use of resources have led to the circular economy as a further growth opportunity. The circular economy has spread in various directions like agriculture and industry. The main focus of circular economy is to minimize or eliminate the use of non-renewable inputs in a production system and to maximize or optimize the reuse of these materials within the same system. In addition, circular agriculture is expected to reduce environmental impacts through soil regeneration and input use. Activities in rice cultivation include sowing, fertilizing, watering, and harvesting, and these activities can be done using biological and other agricultural methods in an environmentally friendly way instead of chemical fertilizers, pesticides, and herbicides, and further minimizing the accumulation of waste. Burning rice straw and husks emits lot of CO2 into the environment. However, these can be used as raw materials for various industries. Rice residue is an excellent source of nutrients and beneficial for human health. Thus, circular economy methods can be used in rice cultivation by cultivating more productive and suitable rice varieties, reducing the amount of waste released into the environment in various ways, and using discarded waste as raw materials for industries. This study focuses on determining the applicability of circular economy methods to rice cultivation and processing. Accordingly, it appears that in the rice industry, circular economy methods are applied to reduce the release of unnecessary air and waste into the environment and effectively reuse the waste. This will create an eco-friendly and safe environment.

The uncontrolled waste generation is a prevailing environmental concern where waste management is a critical issue in Sri Lanka. Even though different methods are practicing, insect-basedbio-degradation is forthcoming. Black soldier fly larvae (BSFL,Hermetia illucens) based emerging technology has recognized for the conversion of biodegradable waste into potentially more sustainable and marketable nutrient rich compost and animal feed rich with crude proteins. The study aims evaluate the potentials to introduce BSFL based biodegradation and to upgrade protein livestock feed sources by overwhelming urban catering bio-degradable waste in Ratnapura, Balangoda and Embilipitiyaurban council areas. Eighty-eight questionnaires were administrated through random sampling and the results were interpreted by descriptive statistics and bivariate correlation. More positively 97.7% were having the waste collection service supplied by local authorities (LA) with 93.2% daily collection. Importantly LA had a policy to collect the separated waste only. Even though 98.8%, 56.8% and 92.0% of the respondents were not known regarding BSFL protein production, live feeding and composting, 55.7% were willing to produce BSFL by their own bio-degradable waste. 46.6% and 71.6% were willing to sell 1kg of compost and BSFL larvae by Rs. 100-Rs.200 price for expected protein upgrade program in future. Further 60.2% were willing to use a BSFL based compost bin where it was requested to be compatible with the limited space. Since locally it is hardly evidenced regarding this insect-based technology, correlation results indicated the need of more awareness mainly BSFL bio-conversion and relevant technical knowhow procedures along with popularize BSFL based protein production.

Due to its naturally occurring medicinal ingredients known as polyphenols, tea attracts the interest of the pharmaceutical and scientific disciplines. Besides the established antioxidant activity, many phenolic compounds in tea exhibit significant antimicrobial activity. Environmental factors and crop management substantially influence the amount and activity of polyphenols available in tea leaves. In Sri Lanka, there are six main agro-ecological regions where tea is grown using either conventional or organic management. Present study focused to determine the effects of tea production system and their growing region on polyphenol content and antimicrobial properties of made tea. Fresh leaf samples were collected from randomly selected tea estates each for organically certified and conventional from major tea growing regions in Sri Lanka. They were manufactured into CTC black tea using a miniature system. Polyphenol content was assessed by ISO standard method, while the anti-bacterial and anti-fungal properties were evaluated using disk diffusion technique against Escherichia coli ATCC 25922 and clinical pathogen of Aspergillus niger. Polyphenol content, anti-bacterial and anti-fungal properties were significantly different (P<0.05) between the tea production systems and among the growing regions, where organic tea had higher polyphenol content, anti-bacterial and anti-fungal properties than conventional teas. The Southern region tea had greater anti-bacterial and anti-fungal properties probably due to the high polyphenol content, while it was the lowest in Uva region. In conclusion, this research presents preliminary evidence that Sri Lankan teas grown and managed organically have superior antimicrobial properties over conventional teas. To confirm the findings, more investigation using time series measurement in all tea-growing regions is suggested.

Fresh leaf samples were collected from randomly selected tea estates each for organically certified and conventional from major tea growing regions in Sri Lanka. They were manufactured into CTC black tea using a miniature system. Polyphenol content was assessed by ISO standard method, while the anti-bacterial and anti-fungal properties were evaluated using disk diffusion technique against Escherichia coli ATCC 25922 and clinical pathogen of Aspergillus niger. Polyphenol content, anti-bacterial and anti-fungal properties were significantly different (P<0.05) between the tea production systems and among the growing regions, where organic tea had higher polyphenol content, anti-bacterial and anti-fungal properties than conventional teas. The Southern region tea had greater anti-bacterial and anti-fungal properties probably due to the high polyphenol content, while it was the lowest in Uva region. In conclusion, this research presents preliminary evidence that Sri Lankan teas grown and managed organically have superior antimicrobial properties over conventional teas. To confirm the findings, more investigation using time series measurement in all tea-growing regions is suggested.","PeriodicalId":250751,"journal":{"name":"Journal of Agriculture and Value Addition","volume":"59 22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116977659","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}
