Abstract
Purpose
This paper aims to identify, analyze and evaluate the major enablers for the sustainable public distribution system (PDS) supply chain in India in lessening food insecurity by distributing essentials food grains at a subsidized rate.
Design/methodology/approach
The major enablers for the sustainable PDS supply chain were explored by conducting the literature survey and discussion with academic and warehouse experts. Then, the fuzzy-DEMATEL (decision-making trial and evaluation laboratory) technique was applied to develop a causal model that analyses the interaction among the identified enablers.
Findings
This study recognizes fifteen enablers through literature survey and experts' opinions. The present work concludes that “proper identification of the PDS beneficiaries” and “willingness and commitment of the top management and policymaker” are the two major enablers for the sustainable PDS supply chain.
Research limitations/implications
This work would be helpful for profoundly understanding the major enablers, and how they are affecting the entire PDS supply chain. The study would be beneficial for the general people and the entire society straightforwardly by providing suggestions for food security.
Originality/value
Identifying and analyzing the major enablers for the sustainable PDS supply chain helps to visualize the problem more effectively and efficiently. Besides, the causal model explains a comprehensive perspective on the identified enablers.

Abstract
Purpose
The purpose of this paper is to assess the health status and risky behaviours of inmates in Nepal.
Design/methodology/approach
This cross-sectional study was conducted in Jhumka Regional Prison, the largest male prison in eastern Nepal from September 2014 to August 2015. Data were collected through face-to-face interviews from 434 randomly selected incarcerated participants using semi-structured questionnaires.
Findings
The mean age of 434 participants was 35.7 years (SD 13.3). The majority (84 per cent) had at least one current health problem, of which the commonest were respiratory (50 per cent), skin (38 per cent) and digestive (26 per cent). Alcohol (73 per cent) and cigarettes (71 per cent) were the most commonly used substances prior to imprisonment. Approximately, 27 and 11 per cent reported illicit drug use and injectable drug use prior to incarceration, respectively. A total of 204 inmates reported having intercourse with sex workers. Of these, 49 per cent did not use a condom in their last intercourse with a sex worker.
Research limitations/implications
This paper illustrates that a wide range of physical and mental health problems exist among incarcerated people in Nepal. The study may lack generalisability, however, as it was conducted in a single male prison.
Practical implications
The paper suggests a need for medical, psychiatric and substance abuse care in correctional settings to improve the health status of the prison population. It is also important to develop screening policies for blood-borne viral and other infectious diseases in the prison.
Originality/value
This is the first study of its kind drawn from prisons in Nepal.

Abstract
Purpose
Fruits and vegetables, being good source of energy, health promoting and protecting compounds with unique taste and flavor, are attracting consumers since ages. These horticultural produces start deterioration just after harvest; therefore, their proper storage is must during transportation and storage to retain maximum quality parameters and for good market value. Best storage conditions are required to prevent growth of micro flora and to maintain the nutritional values of harvested produce. Retailers and processors in every corner of world want to move toward the cheaper ways to increase the shelf life and texture of horticultural crops for better consumer preference. The purpose of this paper is to make consumers and researchers aware about different post harvest malpractices in fresh fruits and vegetables.
Design/methodology/approach
Lot of chemicals like colors, artificial ripening agents, sweeteners and waxes are applied on surface of horticulture produce to siphon off money from consumers, and these have adverse health effects directly or indirectly. Various regulatory agencies have launched various programs, acts and laws for monitoring and avoiding such unhealthy ways. Regulatory bodies launched training programs also for the food handlers and consumers to ensure the food safety from farm to fork.
Findings
This paper will throw light on different malpractices followed by retailers to manipulate the quality which causes adverse health effects and to create consumer awareness regarding such malpractices.
Originality/value
The paper emphasizes on current malpractices followed by retailers to mislead the consumers about fruits’ and vegetable’ quality by using sweeteners, colors and other chemical. On prolonged consumption, such substances lead to major health issues such as attention disorder.

Abstract
Purpose
Noodles are good vehicles for the enrichment and can be enriched with vegetable purees. However, this enrichment can alter quality attributes of noodles with resultant effect on its sensorial attributes. The purpose of this paper is to study the effect of addition of different hydrocolloids on the microstructural and quality characteristics of instant noodles enriched with spinach puree.
Design/methodology/approach
Preliminary trials were carried out for the standardization level of addition of spinach puree in noodle formulation. Carboxymethyl cellulose (CMC) and guar gum were added in the noodle formulation at 0.25, 0.5 and 0.75 per cent level of incorporation. The effect of addition of hydrocolloids was evaluated on the cooking quality, sensory attributes, texture characteristics and microstructure of the noodles.
Findings
The most acceptable ratio for the formulation of the noodles was found to be 40 g spinach puree per 100 g refined wheat flour. Addition of hydrocolloids resulted in the increase in the cooking time, cooking weight, water absorption and swelling index. Significant decrease in the cooking loss was observed with the increase in the level of CMC (from 7.4 to 6.1 per cent) and guar gum (from 7.4 to 7 per cent). Addition of CMC and guar gum up to 0.5 per cent and 0.25 per cent, respectively, improved the texture, overall acceptability and mouthfeel attributing to complimentary interaction between starch, fibre and hydrocolloids observed at microstructural level; however, further increase in the level of incorporation resulted in stickiness and sliminess in the noodle strands.
Practical implications
It is found that 0.5 per cent CMC and 0.25 per cent guar gum can be used for the enhancement of quality characteristics of the spinach puree enriched noodles.
Originality/value
Intervention of incorporation of hydrocolloids in spinach puree–enriched instant noodles delivers healthy and nutritious product without compromising on its sensorial and quality attributes.

Abstract
Purpose
Pearl millet (Pennisetum glaucum) is a rich source of nutrients as compared to the major cultivated cereal crops. However, major factors which limit its utilization are the presence of anti-nutritional factors (phytate, tannins and polyphenols) which lower availability of minerals and poor keeping quality because of higher lipase activity. Therefore, this paper aims to focus on the impact of different processing methods on the nutrient composition and anti-nutritional components of pearl millet.
Design/methodology/approach
This is a literature review study from 1983 to 2017, focusing on studies related to pearl millet processing and their effectiveness in the enrichment of nutritional value through reduction of anti-nutritional compounds.
Findings
From the literature reviewed, pearl millet processing through various methods including milling, malting, fermentation, blanching and acid as well as heat treatments were found to be effective in achieving the higher mineral digestibility, retardation of off flavor, bitterness as well as rancidity problems found during storage of flour.
Originality/value
Through this review paper, possible processing methods and their impact on the nutrient and anti-nutrient profile of pearl millet are discussed after detailed studied of literature from journal articles and thesis.

Abstract
Purpose
The purpose of this paper is to investigate the first three stochastic natural frequencies of skewed sandwich plates, considering uncertain system parameters. To conduct the sensitivity analysis for checking the criticality of input parameters.
Design/methodology/approach
The theoretical formulation is developed based on higher-order-zigzag theory in accordance with the radial basis function (RBF) and stochastic finite element (FE) model. A cubic function is considered for in-plane displacement over thickness while a quadratic function is considered for transverse displacement within the core and remains constant in the facesheet. RBF is used as a surrogate model to achieve computational efficiency and accuracy. In the present study, the individual and combined effect of ply-orientation angle, skew angle, number of lamina, core thickness and material properties are considered for natural frequency analysis of sandwich plates.
Findings
Results presented in this paper illustrates that the skewness in the sandwich plate significantly affects the global dynamic behaviour of the structure. RBF surrogate model coupled with stochastic FE approach significantly reduced the computational time (more than 1/18 times) compared to direct Monte Carlo simulation approach.
Originality/value
The stochastic results for dynamic stability of sandwich plates show that the inevitable source uncertainties present in the input parameters result in significant variation from the deterministic value demonstrates the need for inclusive design paradigm considering stochastic effects. The present paper comprehensively establishes a generalized new RBF-based FE approach for efficient stochastic analysis, which can be applicable to other complex structures too.

Abstract
Purpose
Milk cake is a well-renowned khoa-based dairy product in India, produced either from the buffalo milk or using a specific danedar variety of khoa. Under ambient conditions, shelf-life of milk cake is generally up to 3–4 days, whereas under refrigeration conditions, it can last up to 12–14 days. Therefore, the present study aims to evaluate the effect of modified atmosphere packaging (MAP) to enhance the shelf-life and keeping intact freshness of milk cake under refrigerated conditions (4 ± 2 °C).
Design/methodology/approach
Different gas concentrations of N2 and CO2 (70:30, 50:50 and 90:10) were used as a treatment, whereas control samples were kept under atmospheric air composition. The product was examined for sensory, physicochemical and microbiological parameters at weekly intervals.
Findings
The physicochemical and microbiological attributes displayed gradual elevation with progressive storage period in all the samples. However, the overall sensory profile of the product remained acceptable for a longer duration. Most of the quality parameters in control declined more rapidly with a shelf life of 14 days, in comparison to MAP packed samples, where gas flushing with the ratio 70:30 was found to be best suited for extending the shelf life of milk cake up to 28 days at refrigeration temperature.
Originality/value
To extend the shelf life of milk cake, modified atmosphere was provided with different gas ratios to reach a best-suited environment for sensory, storage life and proximate parameters.
