Abstract

Purpose

Probiotic fermented foods are fast being recognized as health foods. Most of such developed foods are based on dairy products and much less work is available on cereals/legumes which constitute the staple diet in developing nations. In the present study an attempt has been made to develop a barley‐based probiotic fermented food mixture and report its acceptability and nutritional profile.

Design/methodology/approach

Indigenously developed BCGT food mixture containing barley flour, milk coprecipitate, sprouted green gram paste and tomato pulp (2:1:1:1, w/w) was autoclaved (1.5kg/cm2, 15min., 121C), cooled and fermented with 2 per cent liquid culture (containing 106 cells/ml broth). Two types of fermentations were carried out i.e. single culture fermentation [ L. casei, L. plantarum (37C, 24hr.)] and sequential culture fermentation [S. boulardii (25C, 24hr.)+L. casei (37C, 24hr.); S. boulardii (25C, 24hr.)+L. plantarum (37C, 24hr.)]. The lyophilized and rehydrated food mixtures were subjected to organoleptic and nutritional evaluation. The data were statistically analysed for analysis of variance in a completely randomized design according to standard methods.

Findings

All the fermented and lyophilized food mixtures were found to be organoleptically acceptable to human palate and maintained adequate cell viability. The pH of the fermented products varied from 4.13 to 4.55. They had good nutrient profile with crude protein content ranging from 20.87 to 21.81 per cent.

Practical implications

Since the developed product had good acceptability after one month storage at room temperature, it can be considered for commercialization after establishing its health/therapeutic implications.

Originality/value

Till date dairy foods have preferentially been used as the carrier medium for probiotics. This paper explores the possibility of using staple foods as the carrier medium. The consumption of such food mixtures may be useful in controlling pathogens/antibiotics induced diarrhoea as well as in hypercholesterolemia. To authenticate such claims, the results of trials carried out on mice in our lab shall be reported in future communications.

Abstract

Purpose

This study aims to examine the plane wave reflection problem in micropolar orthotropic magneto-thermoelastic half space, considering the influence of impedance as a boundary in a nonlocal elasticity.

Design/methodology/approach

This study presents the novel formulation of governing partial differential equations for micropolar orthotropic medium with impact of nonlocal thermo-elasticity under magnetic field.

Findings

This study provides the numerical results validation for a particular numerical data and expression for the amplitude ratios of reflected waves and identifies the existence of four different waves, namely, quasi longitudinal displacement qCLD-wave, quasi thermal wave qCT-wave, quasi transverse displacement qCTD-wave and quasi-transverse micro-rotational qCTM-wave. The study derives the velocity equation giving the speed and phase velocity of these waves. The study also shows that the small-scale size effect gives significant impact on phase velocity.

Research limitations/implications

The graphical analysis examines the variation of speeds and coefficients of attenuation of these waves due to frequency, magnetic field and nonlocal parameters. Also, significant conclusions on the variation of reflection coefficient against nonlocal parameter, frequency, impedance parameter and angle of incidence are provided graphically.

Practical implications

The creation of more effective micropolar orthotropic anisotropic materials which are very useful in the daily life and their applications in earth science are greatly impacted by the findings of this study.

Originality/value

The authors of the submitted document initiated and produced it collectively, with equal contributions from all members.
