Throughout the world, there has been a dramatic increase in the demand for functional food products. Owing to the health benefits of barley, its utilization was explored for the development of β-glucan rich functional instant talbina (porridge). The present research was, therefore, undertaken with an aim to optimize the extrusion conditions for development of instant talbina premix and evaluate its functional and quality characteristics.

The independent variables i.e. barrel temperature (105–125°C) and feed moisture (12–20%) were studied to determine their influence on the system parameter i.e. specific mechanical energy and product characteristics i.e. bulk density, breaking strength, water absorption index, expansion ratio, water solubility index, L*, a* and b* by employing a central composite rotatable design.

All the quality parameters were significantly (p < 0.05) influenced by independent variables. The regression models obtained for all the responses showed higher coefficient of determination (R² = 0.99). The optimum extrusion conditions obtained by numerical optimization for development of extrudates used for making instant talbina were moisture content (12%) and barrel temperature (105°C). Various functional, pasting, complexing index and physicochemical properties of instant talbina were improved by the addition of honey and milk. The instant talbina prepared from barley flour with the addition of milk and honey showed increase in the β-glucan content, resistant starch, antioxidant activity and decrease in glycemic index with improved overall acceptability.

As far as we could possibly know that very limited or not many studies have been carried out wherein the possibility of developing instant talbina (porridge) have been carried out. As a result, the current study has a lot of potential for the food industry to manufacture β-glucan rich functional instant talbina with improved antioxidant characteristics and low glycemic index.

This study aims to develop sweet chestnut incorporated corn-based extrudates by the optimization of process conditions.

The independent process variables for extrusion (blend ratio, barrel temperature, screw speed and feed moisture) were investigated to govern their impact on reliant variables, namely, bulk density, specific mechanical energy, water absorption index, water solubility index, color and hardness. Product and system responses were significantly (p < 0.05) affected by the independent variables. Experimental design with quadratic models experienced a high coefficient of determination (R² = 0.99).

Numerical optimization for the development of extrudates resulted in optimum conditions having corn flour: sweet chestnut flour (80:20), barrel temperature (120°C), screw speed (340 rpm) and feed moisture (12%). Fat, moisture and protein contents of the developed extrudates using optimum conditions were significantly (p < 0.05) lower compared to raw materials – corn and sweet chestnut. The packaging of extrudates in aluminum laminates revealed shelf stability of three months at room temperature without deterioration of quality.

Nutritionally rich sweet chestnut extruded products would be an exclusive option to already existing snacks in the market and can facilitate a new sphere in extruded product sector.

The demand for functional foods has been increasing tremendously throughout the globe and keeping in view the health beneficial properties of apricot fruit. The purpose of this study is to develop wheat flour based cookies enriched with apricot pulp powder in order to improve nutraceutical properties of cookies and dilution of gluten at the same time.

Cookies were prepared from wheat flour blended with apricot pulp powder at 0, 10, 15, 20 and 25% level and evaluated for proximate, functional, rheological, nutraceutical and sensory properties.

Fibre content of apricot powder-incorporated cookies (3.23%) was significantly (p < 0.05) higher at 25% level than control (1.64%). The water absorption and oil absorption capacities decreased significantly (p < 0.05) upon increasing level of apricot pulp powder. The ß-carotene content, antioxidant activity and total phenolic content increased significantly (p < 0.05) upon incorporation of apricot pulp powder. The thickness of cookies increased, however, diameter and spread ratio decreased with increase in the levels of apricot pulp powder. Lightness (L*) value decreased, while redness (a*) and yellowness (b*) increased when incorporated with apricot pulp powder. Cookies having 25% apricot pulp powder showed maximum hardness and overall acceptability.

To the best of our knowledge, the scientific literature on incorporation of apricot pulp powder in bakery products is scanty. As such the present research has a tremendous scope for the food industries to produce functional bakery products with antioxidant properties and diluted the gluten content at the same time.

The present research was envisaged with an aim to optimize the system and the product responses for the development of tomato pomace-incorporated corn-based extrudates employing central composite rotatable design and determine its proximate, lycopene, consumer acceptability and storage studies.

Lycopene-rich extrudates were developed from corn flour blended with different levels of tomato pomace. The independent extrusion variables, namely, feed composition (95:5 to 75:25), feed moisture (12–20%), screw speed (200–600 rpm) and barrel temperature (125–185 °C), were studied to determine their influence on dependent variables, namely, specific mechanical energy, hardness, water solubility index, lateral expansion, water absorption index, bulk density and color.

All of the quality parameters were significantly (p < 0.05) influenced by independent variables. The regression models obtained for all the responses showed high coefficients of determination (R2 = 0.85–0.95). The optimum conditions for the development of tomato pomace-incorporated corn-based extrudates were feed composition (90:10), feed moisture (14%), screw speed (300 rpm) and barrel temperature (170 °C). The moisture, fat and carbohydrate contents of the extrudates were significantly reduced, whereas protein, ash and fiber were significantly (p < 0.05) enhanced after the incorporation of tomato pomace. Aluminum laminates were found to be the suitable packaging materials for extrudates for a period of 120 days in comparison to high-density polyethylene packages.

As far as the authors could possibly know, scanty literature exists wherein the tomato pomace has been utilized for the development of lycopene-rich corn-based extruded snacks. Such extrudates with significantly higher fiber and lycopene contents than corn flour will serve as a suitable alternative for the development of shelf-stable ready-to-eat extruded snacks.

Apricots are not only nutritionally-rich but also possess pharmacological significance owing to their high antioxidant activity, and they are rich in vitamins, fibers, bioactive phytochemicals and minerals. Because of its immense organoleptic characteristics, apricot juice (AJ) is well accepted; however, it has a limited shelf-life, thereby demanding it to be converted into other shelf-stable form. One of the approaches is converting this juice into dehydrated powder. Amongst the various dehydration techniques available, spray drying is usually preferred; however, it involves the use of several independent variables, which need to be optimized, thus prompting to optimize the process to obtain spray dried apricot powder (SDAP) with improved quality.

The spray-drying process of apricot juice was done using the response surface approach. The process variables included the inlet air temperature of 135–220°C, gum arabic concentration of 4–25%, feed flow rate of 124–730 mL/h, feed total soluble solids (TSS) of 10-30°Brix and atomization speed of 11,400–28,000 rpm. The dependent responses were powder yield, hygroscopicity, solubility, moisture content, carotenoids (CT), ascorbic acid (AA), radical scavenging activity (RSA), lightness, wettability, bulk density, particle density and porosity.

Amongst all independent variables, inlet air temperature had most predominant impact on all the investigated responses. The optimum processing conditions for development of apricot powder with optimum quality were 190°C inlet air temperature, 18.99% gum arabic, 300.05 mL/h feed flow rate, 24°Brix feed TSS and 17433.41 rpm atomization speed. The experimental values were found to be in agreement with the predicted values, indicating the suitability of models in predicting optimizing responses of apricot powder. Flowability as Carr's index (CI) (22.36 ± 1.01%) suggests fair flow of powder. Glass transition temperature of powder was 57.85 ± 2.03°C, which is much higher than that of ambient, suggesting its better shelf stability.

To the best of author's knowledge, very limited or very few studies have been carried out on the spray-drying process for the manufacture of SDAP. The results of this investigation will open up new horizons in the field of food industry in the Union Territory of Jammu and Kashmir, India or elsewhere in the apricot-growing areas of India.

The purpose of this article was to highlight the various methods of extrusion technologies for encapsulation of bioactive components (BACs).

BACs provide numerous health-care benefits; however, downsides, including a strong effect of organoleptic properties by reason of the bitterness and acridity of a few components, and also a short shelf-life, limit their application in food. The food industry is still demanding complicated qualities from food ingredients, which were often impossible to obtain without encapsulation such as stability, delayed release, thermal protection and an acceptable sensory profile. Various techniques such as melt injection extrusion, hot-melt extrusion, electrostatic extrusion, co-extrusion and particles from gas-saturated solutions, could be used for maintaining these characteristics.

Extrusion technology has been well used for encapsulation of bioactive chemicals in an effort to avoid their numerous downsides and to boost their use in food. The count of BACs that could be encapsulated has risen owing to the extrusion technology just as form of encapsulation. Extrusion technique also aids in the devaluation of the fragment size of encapsulated BACs, allowing for greater application in the food business.

The study reported that encapsulating BACs makes them more stable in both the product itself and in the gastrointestinal tract, so using encapsulated BACs would result in a product with stronger preventive properties.

Currently, there is a great demand for those food products that are easy to prepare or ready for direct consumption. Making pear fruit/juice available round the year is desirous owing to pears' high-nutritional value and specific pleasant taste. Pear is, however, a seasonal fruit and under ambient conditions has a limited shelf life rendering it available as fresh fruit for a specific period.

The study aimed to optimize the spray drying process parameters using response surface methodology for the development of pear juice powder. The process variables included the inlet air temperature of 140–210°C, maltodextrin levels of 4–25%, atomization speed of 11,400–28,000 rpm, feed flow rate of 180–630 mL/hr, and feed total soluble solids (TSS) of 13–30°Brix. The dependent responses were powder yield, solubility, antioxidant activity {% 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity}, dispersibility, hygroscopicity and particle density.

Among independent variables, inlet air temperature showed a predominant effect. The optimum processing conditions for the development of pear juice powder with optimum quality were 163.02°C inlet air temperature, 13.50% maltodextrin, 28,000 rpm atomization speed, 390.94 mL/h feed flow rate, and 25.5°Brix feed TSS. Under these optimum conditions, pear powder with desirable properties could be produced. The experimental and predicted values were found to be in agreement, indicating the suitability of the model in predicting optimizing responses of pear powder. Glass transition temperature of pear powder was found to be 36.60 ± 0.40°C, which is much higher than that of ambient temperature, suggesting better shelf stability.

The processing of pear fruit has resulted in the increased demand for pear juice powder in both domestic and international markets as a primer of new food products. The optimum conditions obtained in the current study could provide a new insight to the food industry in developing spray-dried pear powder of optimum quality. This can open up a new horizon in the field of food industry for the common masses of Jammu and Kashmir, India.

The purpose of this paper is to build a relationship between the quantitative and structural indicators of maqashid sharia studies produced from bibliometric analysis and the conceptual discussion developed through a thorough review of selected key literature.

The study uses bibliometric analysis, collecting information drawn from 219 articles published in 68 journals during the period of 2006–2022. This study uses VOSviewer, RStudio, Microsoft Excel, and an examination of research time periods using the Scopus database to illustrate the citation analysis and keyword map. It is also strengthened by content analysis of selected studies.

The main research theme found in this study is the application of maqashid sharia in Islamic banks, with Islamic banks and Islamic finance among the most frequently used keywords. Meanwhile, the geographical spread of maqashid sharia research has reflected its universal acceptance, as it has spread across both Muslim-dominant and non-Muslim-dominant countries. Besides, maqashid sharia is found to be an extremely important subject for ensuring the ethical dimension of Islamic finance products and services, a more inclusive human development index, and contributing to the international agenda of Sustainable Development Goals. Lastly, future research is expected to broaden it into a multi-dimensional horizon, with several recommendations offered to enrich the understanding of maqashid sharia.

The findings of this study can be beneficial to multiple stakeholders in Islamic finance industry, including the management of Islamic banks, who can enhance the values of maqashid sharia in designing their products/services, and the regulators, who can formulate regulatory frameworks which are reflective of maqashid sharia principles.

This study will assist future scholars in this field to formulate and design exciting research ideas and models to address the deficiencies found in the current implementation of maqashid sharia within Islamic finance industry.

The primary contribution of this study is to provide comprehensive review and discussion of selected significant literature on maqashid sharia and give direction for future research. In addition, this study also extends and incorporates the results of bibliometrics using the recent maqashid sharia studies published at the end of 2022.

This study aims to examine the factors that determine consumer behaviour of ijarah home financing using the Islamic theory of consumer behaviour (ITCB). In particular, the specific contract used is al-ijarah muntahia biltamleek. Subsequently, the term al-ijarah muntahia biltamleek home financing is used throughout the paper.

Drawing upon the ITCB, the present study examines patronage factors for al-ijarah muntahia biltamleek home financing. This study’s data were drawn from valid 409 usable questionnaires.

Partial least square results suggest that the role of iman, Islamic mortgage support and maqasid consumer index are significantly related to consumer behaviour. In turn, consumer behaviour is instrumental in determining religious satisfaction.

Two limitations were observed that provide direction for future studies. Firstly, the current study is only tested in one particular Islamic home financing product that may explain why the generalisation is an issue. Secondly, the theory is still in its infancy stage, which, of course leads to some criticisms pertinent to its parsimony and applicability to other settings. Despite these limitations, however, this study aims to suggest a so-called Islamic model of factors that can explain consumer behaviour of a particular Islamic home financing product. In particular, scrutinising the product acceptance from the context of the ITCB can open a new debate in this area.

This study indeed reduces the theory–practice gap by suggesting new indicators that are workable to improve consumers’ positive perception of Islamic home financing. Given the results obtained, the ITCB provides a better prediction for consumer behaviour of al-ijarah muntahia biltamleek home financing.

This study expands the applicability of the ITCB to include al-ijarah muntahia biltamleek home financing.

Because of the huge advantages of Islamic credit cards for both banks and customers, the purpose of this study is to examine the main factors that influence consumers to use an Islamic credit card (ICC).

Accordingly, the innovation diffusion theory, customer awareness and loyalty concept are considered because of their ability to predict behavior and also to provide valuable information. The proposed research model of the study was empirically validated using data collected from 397 bank customers in Kish Island, Iran. Partial least squares-structural equation modeling was used to analyze the collected data from respondents.

The results indicated that relative advantage and compatibility have a significant direct effect on ICC loyalty. The significant connection between ICC loyalty by bank customers and their decision to have positive word of mouth was also confirmed.

This study represents a basis for further refinement of individual ICC acceptance and loyalty models for researchers. For practitioners, organizations and banks would be able to redesign and manage-related factors, which, in turn, would increase the probability of ICC acceptance and usage success by bank customers.
