The utilization of composite flour in the development of cookies is replacing wheat flour thereby enhancing the quality of the product. But, the quality assessment of cookies made with composite flour is greatly influenced by storage conditions. Therefore, the present research was conducted to evaluate the storage stability of wheat-breadfruit incorporated cookies. Cookies were prepared from wheat flour and breadfruit flour in different combinations. Based on the nutritional and sensory properties of freshly prepared cookies, the three best treatments were selected along with the control for the shelf-life evaluation and packed in aluminium laminated foil and stored under the conditions of 30 ± 1 ◦C temperature and 75-80% RH. Quality evaluation was done at two weeks intervals for 12 weeks of the storage period. Among the treatments, cookies prepared from 40% breadfruit flour contained 4.97% of moisture, 2.62% of ash, 9.46% of protein, 1.51% of fibre and 16.46% of fat content after 12 weeks. According to the sensory analysis, there were significant differences (p<0.05) among the treatments in terms of colour, taste, texture, aroma and overall acceptability. Microbial counts were within the acceptable range up to the entire storage period. Therefore, based on the nutritional, organoleptic and microbial qualities, the cookies produced with 40% of breadfruit flour was the best treatment compared to other combinations at the end of 12 weeks storage period. 2021-12-30T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/6402 Title: Prediction of forex rate using deep learning: us dollar to Sri Lankan rupees Authors: Faathima Fayaza, M. S.; Raheem, Fanoon; Iqbal, Nihla Abstract: —Exchange rate forecasting is a vital problem in the economic aspect of every country in the world. Prediction of the foreign exchange rate is a very complex and challenging task. A more in-depth analysis and forecasting techniques assist the traders in good decision-making in their commercial activities. This paper discusses forecasting of USD to LKR foreign exchange rate using Artificial Neural Network (ANN) and Recurrent Neural Networks (RNN). This study used two variant Recurrent Neural Networks, Long Short Term Memory (LSTM) and Gated Recurrent Unit (GRU). Rectified Linear Unit (ReLU) is used as an activation function. Adam and Stochastic Gradient Descent (SGD) are used as the optimizers in this research. The study mainly compares the performance of ANN, LSTM, and GRU prediction rates with two different optimizers Adam and SDG. Mean Square Error (MSE) is used as the loss function. The study finds that GRU with Adam optimizer performs better than other approaches in terms of R2 squared (Coefficient of determination), Root Mean Squared Error (RMSE), Mean Absolute Error (MAE). In contrast, LSTM performs better with SDG optimizer when compared to Adam. 2021-12-30T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/6401 Title: Review of home garden as an economic approach Authors: Seyida Afreen, Seyid Mohamed Moulana; Rasmiya Begum, Sulaima Lebbe; Seyida Himaya, Seyid Mohamed Moulana Abstract: Over the years, there has been a developing enthusiasm to fortify and heighten nearby food creation to relieve the unfriendly impact of worldwide food stuns. The household garden was neglected by macroeconomics over time. Supportable creation and great financial conditions can be accomplished by home planting. Thusly, there is a lot of consideration in the direction of home gardens using a technique toward upgrade family unit foodstuff safety plus money. Despite the importance, the economic contribution is one of the least studied area regarding home gardening. A theoretical approach from all the available published international and national level papers was reviewed regarding home gardens definitions, attributes and afterwards gives a worldwide study of their social, financial, and environmental commitments to the host communities. Improving the fitness of humans, enhancing food and dietary security and social value, and gender orientation balance are given as social benefits of home gardening. The valuation shows that producing from the home garden is more beneficial than spending money on food from the market. The cost-benefit analysis is cost-effective when family members are used as labours. The household members earn more money by the trade of both urban and rural home garden products in most probably developing countries. However, while accentuating numerous advantages, we also feature few limitations like the absence of water accessibility, lack of capital, atmosphere vulnerability, and market disappointment in their development. The review gives consolidated information on the home garden as an economical approach. Even though better selection of harvests and diverse land use designs received cause them to endure and continue with their creation. From this review, the exciting knowledge on the economic importance of home gardening will be concentrated on the youth. 2021-12-30T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/6399 Title: Internet of things (IOT) enabled food technologies: a systematic review approach Authors: Mohamed Nafrees, Abdul Cader; Abdul Majeed, U. L; Kariapper, Rifai; Razith, Suhail; Pirapuraj, Ponnampalam Abstract: —Information and communication technology provide tremendous services to all the sectors including food technologies. On the other hand, this world fighting against hunger, food wastes, and nutrition-less food. There are much more technologies increase not only the profitability but also quality and production rate. IoT technologies use by the food technologies in many countries for food safety, transportation, packaging, temperature monitoring, nutrition analysis, and find the defective foods using IoT devices and applications via smart phones and computers in real time. This study mainly focused on IoT in food technologies in terms of the food production, security issues and possible solutions for those issues. For that, a systematic literature review was conducted and analyzed using qualitative method. Findings confirmed that, IoT and relevant technologies positively provide its full support to increase the demand and quality of food production process. Meanwhile, data privacy issues and provide immediate technical solutions were the major security issues faced by those IoT devices and application. In addition to that, none of the articles found conducted in Sri Lanka related to this study and none of the studies found related to IoT, Food technology Food-destroying robes. Apart from these all, this study suggested developing IoT systems and applications based on cloud computing to drive away from the food-destroying robes. Finally, it is planning to conduct a statistical analysis to find the expectations of food scientists, food production industrialists, and farmers. This paper purely based on past research works from famous Journals and conferences. 2021-12-30T00:00:00Z
