This study aims to evaluate the effect of cell immobilization on bioactive property of lactobacilli‐fermented soymilk.

Abstract

Purpose

This study aims to evaluate the effect of cell immobilization on bioactive property of lactobacilli‐fermented soymilk.

Design/methodology/approach

Agrowastes from durian (Durio zibethinus), cempedak (Artocarpus champeden), and mangosteen (Garcinia mangostana) were used as immobilizers for lactobacilli (Lactobacillus acidophilus FTDC 1331, L. acidophilus FTDC 2631, L. acidophilus FTDC 2333, L. acidophilus FTDC 1733, and L. bulgaricus FTCC 0411) in soymilk fermentation. Fermented soymilk was stored at different temperatures (4°C, 25°C and 37°C) for 168 h and sampled for analyses periodically.

Findings

Scanning electron micrographs showed that cells of lactobacilli were immobilized onto the matrix of agrowastes powder. The proteolytic activity was higher in soymilk supplemented with immobilized lactobacilli at 37°C and 25°C compared to that at 4°C. Soymilk fermented by cells immobilized on cempedak rind powder showed higher proteolytic activity (p<0.0001), followed by durian and mangosteen rinds powder (p<0.001). The highest ACE inhibitory activity was also found in soymilk fermented by cells immobilized on cempedak rind powder for all temperatures studied (p<0.0001). In addition, ACE inhibitory activity was higher in soymilk fermented at 37°C, compared to 25°C and 4°C (p<0.0001).

Originality/value

The results in the paper show that cell immobilization enhances the bioactive property of fermented soymilk, in terms of proteolysis and in‐vitro ACE inhibitory activity.

Abstract

Purpose

The purpose of this paper is to understand the status of a class of non‐permanent labour in the globalised era in India.

Design/methodology/approach

To understand this the paper uses both secondary level information and primary data collected through a survey. Secondary level data are analysed using a panel data model. Here, the hypothesis is: contribution of contract labour to production is greater than that of the regular employees. The primary level survey is conducted to know whether they are exploited due to their non‐permanent stature.

Findings

It is observed from secondary data analysis that the hypothesis is not rejected. Contract labour makes a significant contribution to production, while the regular employees do not. Primary survey also shows that they are exploited in many ways including through non‐payment of minimum wages.

Practical implications

The paper indicates that, while regulations are in place, they are abused and hence it is the implementation part on which government needs to focus.

Originality/value

Analysis shows how rationalization of employment does not take place due to labour regulations for the regular employees. It also brings to light through primary survey various lacunae in the implementation of the Contract Labour Act. Since survey of such labour class is difficult there are limited studies in this field.

Abstract

Purpose

The aim of this study is to develop a soy‐based cream cheese (SCC) with textural characteristics comparable to that of commercial dairy cream cheese (DCC) via the addition of microbial transglutaminase (MTG), soy protein isolate (SPI) and maltodextrin (MD).

Design/methodology/approach

Response surface methodology (RSM) was employed in this study to determine the effects of MTG, MD and SPI on firmness of SCC.

Findings

The second‐order model generated via RSM was significant with only a 9.76 per cent variation not explained by the model. The coefficient of regression revealed that MTG, MD and SPI showed significant linear effects (P<0.0001) on the firmness of SCC, while MTG and SPI showed significant quadratic effects. The model successfully predicted and developed a SCC model with similar firmness as that of DCC; via the combination of 2.57 per cent (w/w) of MTG, 19.69 per cent (w/w) of SPI and 19.69 per cent (w/w) of MD. Physicochemical analyses revealed that SCC possessed lower fat content, reduced saturated fatty acid and zero trans fat. Further rheological measurements revealed that SCC was more solid‐like at room temperature, but less elastic at refrigerated temperature compared to DCC. SEM and SDS‐PAGE analyses affirmed that the textural changes of SCC were attributed to MTG‐induced cross‐linking.

Originality/value

The research demonstrated that a non‐dairy cream cheese could be developed using soy. In addition, the SCC also contained better nutritional properties compared to its dairy counterpart.

Abstract

Purpose

The aim of this study is to examine the bioactive properties of lactobacilli‐fermented B‐vitamin soymilk, namely the in‐vitro antihypertensive property and bioconversion of isoflavone glucosides to aglycones.

Design/methodology/approach

Lactobacillus acidophilus BT 1088, L. fermentum BT 8219, L. acidophilus FTDC 8633 and L. gasseri FTDC 8131 were investigated for their bioactive potential and enhanced bioconversion of isoflavones in soymilk supplemented with individual B‐vitamins at a concentration of 1 mg/L.

Findings

The supplementation of thiamine, riboflavin, niacinamide, calcium pantothenate, biotin and folic acid enhanced the ACE‐inhibitory activity of lactobacilli in soymilk accompanied by a lower IC50 value compared to the control (P<0.05). The β‐glucosidase specific activity of lactobacilli was also enhanced on supplementation of B‐vitamins, leading to increased bioconversion of isoflavones in soymilk. The concentration of genistein was decreased, accompanied by an increased concentration of genistein on fermentation in the presence of thiamine, niacinamide, biotin, calcium pantothenate and folic acid. Additionally, the supplementation of niacinamide, calcium pantothenate, biotin and folic acid also led to lower concentrations of malonyl daidzin, indicating increased hydrolysis of malonyl daidzin to daidzin. Results from the present study indicated that the supplementation of B‐vitamins could enhance the bioactive potential and bioconversion of isoflavones in lactobacilli‐fermented soymilk.

Originality/value

This work has shown that the supplementation of B‐vitamins in lactobacilli fermented soymilk has exerted in vitro ACE‐inhibitory activity and increased the accumulation of bioactive isoflavone aglycones. To the authors' knowledge, this is the first evaluation reporting on such aspects.

Abstract

Purpose

The purpose of this paper is to propose a conceptual framework for the application of blockchain in the Public Distribution System (PDS) in India to manage the supply of food grains to the targeted beneficiaries. The framework will help prevent diversions and leakages of grains at the warehouse and Fair Price Shop (FPS) level. The paper also identifies the enablers and disablers in the context of the framework.

Design/methodology/approach

This paper will firstly review the previous literature in PDS and blockchain-enabled agricultural and food supply chains. The study then proposes a framework that could be implemented in the PDS in India using blockchain technology.

Findings

The proposed framework provides an effective way to combat corruption, exclusion errors of targeted beneficiaries, leakage of PDS food grains and is cost-effective. The identified enablers and disablers give an insight into the application of blockchain in PDS in India.

Research limitations/implications

The research work may have implications for the Ministry of Food and PDS (Central Government), Food Corporation of India and State Governments to manage the supply of the grains more efficiently and effectively.

Originality/value

The current study caters to the implementation of blockchain technology starting from the warehouse level to the FPSs and consumers and simultaneously connecting them to concerned authorities to ensure transparency and accountability.

Abstract

Purpose

The increased health-care costs, improved service quality and sustainability-oriented customer demand have forced the health-care sector to relook their current process. The present work deals with the identification, analysis and prioritization of just in time (JIT) enablers in the health-care sector.

Design/methodology/approach

JIT leads to waste reduction, improves productivity and provides high-quality patient care. The practical implementation of JIT depends on vital factors known as enablers. The enablers have been found through the comprehensive literature review and prioritized using responses from different health-care facilities of the national capital region of India. Grey relational analysis (GRA) has been used in the present study to rank enablers and ranks were further validated using the fuzzy technique for order of preference by similarity to ideal solution (TOPSIS) and sensitivity analysis.

Findings

It has been found that top management support, teamwork and real-time information sharing are the most significant enablers of JIT in health care with grey relational grades 0.956, 0.832 and 0.718, respectively. The corresponding closeness coefficients of the fuzzy TOPSIS for the enablers were found as 0.875, 0.802 and 0.688, respectively. The findings of the present research work will facilitate the health-care organizations to implement a comprehensive JIT approach that further leads to improved patient care at a low cost.

Originality/value

The present study is unique in terms of the exploration of the readiness measures or enablers of JIT using GRA and fuzzy TOPSIS. The findings of the present research work will facilitate the health-care organizations to optimize their resources for better patient care.

Abstract

Purpose

The purpose of present study is to expose the detailed review for benefits and challenges about implementation of Lean Six Sigma (LSS) in business organization and spread of LSS literature in term of various sectors wise, research methodology wise and journal wise.

Design/methodology/approach

This paper covers the literature on LSS from 2000 to 2018. The authors have selected a large number of research papers using the keywords as Lean Six Sigma implementation in automotive, micro small medium enterprises, health care, education, financial sectors and many more. A total of 216 research papers have been reviewed on LSS distribution of sector wise, research methodology adopted, active countries, year of publication and critical barriers in implementation of LSS.

Findings

The present literature classifies the spread of LSS in four important sectors of manufacturing, health care, human resource, financial and education. It presents the critical barriers and benefits of LSS implementation in various sectors mentioned above and an important research gap, where practitioner/researcher can focus more during their research on LSS.

Practical implications

It is important for industry, researchers and LSS practitioners to be aware about challenges and success factor during LSS implementation in various sectors such as manufacturing, education, financial, human resource and health care. Hence, this paper could provide significant and valuable insights to industry and practitioners for successful implementation of LSS projects.

Social implications

LSS results in reduced waste, defects and improve process, which in turn provide high-quality products at minimum cost, and this leads to customer delight, which ultimately raises the societal living standard. The results encourage LSS practices without fear because there is a huge discussion of near about all success and failure parameters about LSS.

Originality/value

To the authors’ best knowledge, no studies have still covered the literature review of LSS implementation in three different sectors: manufacturing, service and process. The present study was mainly focused on presenting a systematic review of literature in said sectors and found the gap between current status and future direction for the implementation of LSS in different areas.

Abstract

Purpose

This paper examines the prices of fishery products (an important source of protein for the poor) and drivers of their inter-regional variations in India, where fishery is a critical sector. By explaining regional price differences, we make an attempt to derive policy implications as to how fish price inflation can be controlled.

Design/methodology/approach

The paper is primarily based on secondary data provided by the Ministry of Agriculture, Government of India. In the absence of data on inter-regional trade, appropriate indicators are constructed using the gravity model to capture supply side factors that may influence regional price differences. Pooled regressions are carried out for a representative marine and an aquaculture fish variety separately for the period 2011 to 2017.

Findings

After controlling for income levels, it is found that marine fish prices can be reduced by improving intra-state transport infrastructure. For reducing the price of aquacultures, it is shown that it is imperative to reduce the distance between producers and consumers.

Research limitations/implications

The study is limited by the availability of data on interstate trade and consumption of fish and has only used prices of representative fish varieties instead of average marine and aquaculture fish prices.

Originality/value

This paper considers trade and value chain based business theories to explain regional price differences. It analyzes the drivers of relative price differences and suggests measures to control them using a gravity model of trade.

Abstract

Purpose

This article aims to study the tensile properties of a functionally graded composite structure with Al–18wt%Si alloy as the matrix material and silicon carbide (SiC) particles as the reinforcing element. More specifically, the study's primary objective is to optimize the composition of the material elements using a robust statistical approach.

Design/methodology/approach

In this research, the composite material is fabricated using a combination of stir casting and the centrifugal casting technique. Moreover, the test specimen required to study the tensile strength are prepared according to the ASTM (American Society for Testing and Materials) standards. Eventually, optimal composition to maximize the tensile property of the material is determined using the mixture design approach.

Findings

The investigation results imply that the addition of the SiC plays a crucial role in increasing the tensile strength of the composite. The optical microstructural images of the composite show the adequate distribution of the reinforcing particles with the matrix. The proposed regression model shows better predictability of tensile strength. In addition, the methodology aids in optimizing the mixture component values to maximize the tensile strength of the produced functionally graded composite structure.

Originality/value

Little work has been reported so far where a hypereutectic Al–Si alloy is considered the matrix material to produce the composite structure. The article attempts to make a composite structure by using a combination of stir casting and centrifugal casting. Furthermore, it employs the mixture design to optimize the composition and predict the model of the study, which is one of a kind in the field of material science.

Abstract

Purpose

ISO 9001 can offer users substantial management benefits. For developing country firms, this standard could offer both important management improvements and serve as a quality signal to foreign suppliers and potential buyers. The purpose of this paper is to explore the impact of ISO 9001 on food manufacturing firms in Guyana.

Design/methodology/approach

A multiple case study approach, using interviews with multiple managers, was used to assess the impacts of ISO 9001 in six registered and non-registered firms.

Findings

ISO 9001 offers supply chain management benefits. Non-registered firms reported using the standard to formalize their monitoring procedures and improve planning, sourcing, manufacturing, and delivery efficiency. Registration helped firms formalize their quality management systems; it provided guidance on improving their customer/supplier relationships, and offered tools to monitor internal processes. Registered and non-registered firms reported increased customer satisfaction, market share and inventory turnover, and reduced lead times, rework, waste, and customer complaints.

Research limitations/implications

The number of cases examined in this study is limited. Interview data are based on managers’ perceived experiences; it was not possible to verify this information independently.

Originality/value

The paper examines management benefits of adopting an international quality management standard in developing country agrifood firms.
