Development of Dietary fiber fortified Beetroot Ready to Serve Beverage
Vegetables play a significant role in human nutrition, especially as sources of vitamins, minerals, dietary fiber and phytochemicals. The fraction of vegetable residues that remains after juice processing contains plenty of bioactive compounds. Hence the present investigation was carried out to standardize beetroot residue fortification as dietary fiber into beetroot Ready to Serve (RTS) beverages. Dietary fiber was extracted from the beetroot residues after juice extraction. The beetroot RTS beverages were fortified with different concentration levels (0.5%, 1% and 3%) of dietary fiber with the aim of increasing the dietary fiber intake. The overall acceptability score was 9.0 for control, 8.9 for T1 (0.5 % addition of dietary fiber), 8.0 for T2 (1.0 % addition of dietary fiber) and 7.5 for T3 (3.0 % addition of dietary fiber) samples respectively. The clarity and turbidity values increased as the dietary fiber content increased. RTS beverage fortified with 0.5 per cent dietary fiber was found to be best in their sensory characteristics and physical properties. The acidity of beetroot RTS (T1) was observed as 0.35 per cent, vitamin C content 18.76 mg/ 100 ml, reducing sugar content 3.68 %, total sugar content 8.67 % and total dietary fiber content 0.9 %. The standardized RTS beverages were packed in glass bottles and PET bottles and stored under refrigeration and storage studies performed. RTS beverages showed an increasing trend in pH, TSS, reducing sugar, total sugar and total dietary fiber whereas a decreasing trend in acidity and vitamin C content during storage. The increase in microbial load for 45 days of storage was negligible and safe for consumption. The fruits and vegetables waste could be effectively utilized as a functional ingredient in processed foods.
Changes in polyamine metabolites and biochemical parameters under water deficit in blackgram
Polyamines, especially putrescine (Put), spermidine (Spd) and spermine (Spm) have been implicated in a wide range of biological processes, including growth, development and apoptosis. They are also associated with responses of plants to drought stress. A pot culture experiment was conducted to study the effect of exogenous application of polyamines – Spermine, Spermidine and Putrescine during water stress in blackgram KKM1. Water stress was imposed from 25 DAS followed by foliar application of Put (0.2 mM), Spd (0.2 mM), and Spm (0.2 mM) on 30 DAS. On 35 DAS, assessed the leaf samples for biochemical attributes - Proline, Chlorophyll, Soluble sugars, Total free aminoacid, RWC, Catalase and Peroxidase. The effect of exogenous polyamine application on growth attributes and yield attributes in blackgram under water stress were recorded. The results demonstrated that polyamines (Spd, Spm, Put) on exogenous application mitigated water stress in blackgram and treatment with spermidine had improved water stress tolerance and there is feasibility of polyamines serving as metabolic marker of water stress.
Stakeholder Mapping of Select Millet Processing Chain in Pudukkottai District
Millet is considered to be nutri cereals and there is rise in demand nowadays due to its nutritional benefits. Millets are drought tolerant crops and are predominantly grown as rainfed crops in Kharif and on conserved moisture in Rabi. Stakeholder mapping is a collaborative process of research, debate, and discussion that is drawn from multiple perspectives to determine a key list of stakeholders across the entire spectrum. The first step in the mapping process is to identify the stakeholders. After the identification of the stakeholders, further analysis was made to understand their relevance and the perspective they offered to millet processing chain. The stakeholders were prioritized based on list of criteria developed by Business for Social Responsibility (BSR). The millet processing chain comprised of different stages and the stakeholders of the chain were identified from sourcing to delivery of end product. The stakeholder analysis revealed the importance of various stakeholders in millet processing chain in Tamil Nadu with respect to their expertise and value contribution. The analysis also captured the nature and degree of relationship among the identified stakeholders.
Unlocking the Potential of Internet of Things (IoT) and Agritech – A Case of Agritech Startup Model
Internet of Things (IoT) is the recent buzzword widely applied in the domain of agriculture and was first coined by Kevin Ashton in the year 1999. According to NITI Aayog, 2023, it was reported that India's current market size of agritech sector was valued at USD 204 Million and has significantly low market penetration of one percent of the overall agritech market potential (USD 170 billion). Primary data (30) were collected from different stakeholder’s viz., Startups and technology experts in the domain of IoT agritech startups were telephoned, interviewed, focus group discussions and through online interactions to identify the gaps. Simple table and percentage analysis techniques were employed for this study. IOT applications in Agriculture are implemented in entire supply chain (i.e) Pre harvest (83.33 %) and post-harvest including marketing (16.67%). Agritech startups innovate products and processes in entire agriculture supply chain. Majority of the respondents reported that IoT devices were owned by startups in case of pay per usage, subscription, platform based and monetize your data model except own your device model.
An Empirical Investigation of Agricultural Output and Employment Generation Nexus in the Nigerian Agricultural Sector: A Gender Perspective
One of the factors contributing to the agricultural sector's underperformance in the majority of developing nations is the fact that women do not have equal access to resources and opportunities like their male counterparts. Against this background, this study examines the impact of agricultural output on female employment in the agricultural sector in Nigeria. The main research question is whether increased agricultural output leads to increased female employment opportunities in Nigeria`s agricultural sector. Data from 1990 to 2021 were extracted from the World Bank database with the application of DOLS and Granger causality techniques in estimating the objective of the study. The results of the study found that government spending on agriculture had a negative but significant influence on female employment in the Nigeria`s agricultural sector. Whereas, agricultural output had a favorable but insignificant impact on female employment in the country`s agricultural sector. Furthermore, there is one-way feedback between government spending and female employment in the Nigerian agricultural sector. Therefore, this study recommends that a more holistic approach is needed if the Nigerian government is to effectively address the issue of female employment in the agricultural sector. Also, the Nigerian policymakers should embark on massive disbursement of funds on agricultural sector if female employment in agriculture is the goal of the policymakers.
