Abstract

Purpose

Nature and occurrence of food-borne pathogens in raw and processed food products evolved greatly in the past few years due to new modes of transmission and resistance build-up against sundry micro-/macro-environmental conditions. Assurance of food health and safety thus gained immense importance, for which bio-sensing technology proved very promising in the detection and quantification of food-borne pathogens. Considering the importance, different studies have been performed, and different biosensors have been developed. This study aims to summarize the different biosensors used for the deduction of food-borne pathogens.

Design/methodology/approach

The present review highlights different biosensors developed apropos to food matrices, factors governing their selection, their potential and applicability. The paper discusses some related key challenges and constraints and also focuses on the needs and future research prospects in this field.

Findings

The shift in consumers’ and industries’ perceptions directed the further approach to achieve portable, user and environmental friendly biosensing techniques. Despite of these developments, it was still observed that the comparison among the different biosensors and their categories proved tedious on a single platform; since the food matrices tested, pathogen detected or diagnosed, time of detection, etc., varied greatly and very few products have been commercially launched. Conclusively, a challenge lies in front of food scientists and researchers to maintain pace and develop techniques for efficiently catering to the needs of the food industry.

Research limitations/implications

Biosensors deduction limit varied with the food matrix, type of organism, material of biosensors’ surface, etc. The food matrix itself consists of complex substances, and various types of food are available in nature. Considering the diversity of food there is a need to develop a universal biosensor that can be used for all the food matrices for a pathogen. Further research is needed to develop a pathogen-specific biosensor that can be used for all the food products that may have accuracy to eliminate the traditional method of deduction.

Originality/value

The present paper summarized and categorized the different types of biosensors developed for food-borne pathogens.

Abstract

Purpose

The amount of food wasted every year is 1.3 billion metric tonne (MT), out of which 0.5 billion MT is contributed by the fruits processing industries. The waste includes by-products such as peels, pomace and seeds and is a good source of bioactive compounds like phenolic compounds, flavonoids, pectin lipids and dietary fibres. Hence, the purpose of the present study is to review the novel extraction techniques used for the extraction of the bio active compounds from food waste for the selection of suitable extraction method.

Design/methodology/approach

Novel extraction techniques such as ultrasound-assisted extraction, microwave-assisted extraction, enzyme-assisted extraction, supercritical fluid extraction, pulsed electric field extraction and pressurized liquid extraction have emerged to overcome the drawbacks and constraints of conventional extraction techniques. Hence, this study is focussed on novel extraction techniques, their limitations and optimization for the extraction of bioactive compounds from fruit and vegetable waste.

Findings

This study presents a comprehensive review on the novel extraction processes that have been adopted for the extraction of bioactive compounds from food waste. This paper also summarizes bioactive compounds' optimum extraction condition from various food waste using novel extraction techniques.

Research limitations/implications

Food waste is rich in bioactive compounds, and its efficient extraction may add value to the food processing industries. Hence, compressive analysis is needed to overcome the problem associated with the extraction and selection of suitable extraction techniques.

Social implications

Selection of a suitable extraction method will not only add value to food waste but also reduce waste dumping and the cost of bioactive compounds.

Originality/value

This paper presents the research progress on the extraction of bioactive active compounds from food waste using novel extraction techniques.

Abstract

Purpose

In a developing country like India, consumers are shifting from high-energy diet to balanced nutritional diet, which enhances the metabolic, physiological, functional and health benefits of consumers. The growing self-care and health-embracing population made the probiotic sector as lucrative market for functional food manufacturers and suppliers. Therefore, an analysis is required to understand consumers’ knowledge and buying behavior regarding probiotic products for product innovation and development.

Design/methodology/approach

Awareness, knowledge and consumption patterns of probiotic products were investigated among randomly selected 306 consumers in the Sonipat city of Haryana, which comes in the proximity of national capital, i.e. Delhi, India. A structured questionnaire with exploratory characteristics was developed and face-to-face interviews were conducted as a part of data collection.

Findings

The inference is that there is immense potential for the probiotic fruit beverage market as a higher proportion of the population was interested in probiotic products delivered with fruits as a base matrix followed by dairy products. Further, government’s initiation and support are required not only for manufacturing such health-beneficial products having therapeutic value but also to spread awareness regarding the necessity of including such products in the meals of the growing children.

Originality/value

The study shows changing customer attitudes toward probiotic products and sheds light on consumers’ preference on the medium (food matrix) of probiotic delivery, thereby exploring market opportunities in the area of the functional food sector.
