Application Of Nanotechnology In Food Science

Food Science and Technology

Nanotechnology, in the context of food science, refers to the manipulation of matter at the nanoscale to develop novel materials, processes, and applications for improving food quality, safety, and sustainability. This interdisciplinary field encompasses various innovative approaches, including nanoencapsulation, nanosensors, and nanoemulsions, to address challenges such as food spoilage, nutrient delivery, and pathogen detection. Nanoencapsulation techniques enable the targeted delivery of bioactive compounds, vitamins, and flavors, enhancing their stability and bioavailability in food products. Nanosensors facilitate real-time monitoring of food quality parameters like freshness, contamination, and temperature, thereby ensuring food safety throughout the supply chain. Nanoemulsions, characterized by their small particle size, offer improved stability and texture in food formulations, leading to enhanced sensory experiences for consumers. These applications underscore the potential of nanotechnology to revolutionize various aspects of the food industry, from production to consumption, by introducing advanced materials and techniques that address critical needs and enhance the overall food experience.

Nanotechnology deals with various structures of matter having dimensions of the order of a billionth of a meter. From the advent of nanotechnology, people realized that certain materials can exhibit different properties based on its size and shape. Recent innovations in nanotechnology have transformed a number of scientific and industrial areas including the food industry. Applications of nanotechnology have emerged with increasing need of nanoparticle uses in various fields of food science and food microbiology, including food processing, food packaging, functional food development, food safety, detection of foodborne pathogens, and shelf-life extension of food and/or food products. This work summarizes the potential of nanoparticles for their uses in the food industry in order to provide consumers a safe and contamination free food and to ensure the consumer acceptability of the food with enhanced functional properties. Aspects of application of nanotechnology in relation to increasing in food nutrition and organoleptic properties of foods have also been discussed briefly along with a few insights on safety issues and regulatory concerns on nano-processed food products.

1.0                                          INTRODUCTION

1.1                            BACKGROUND OF THE STUDY

Over the past few decades, nanotechnology has increasingly been considered as to be attractive technology that has revolutionized the food sector. It is a technology on the nanometer scale and deals with the atoms, molecules, or the macromolecules with the size of approximately 1–100 nm to create and use materials that have novel properties. The created nanomaterials possess one or more external dimensions, or an internal structure, on the scale from 1 to 100 nm that allowed the observation and manipulation of matter at the nanoscale. It is observed that these materials have unique properties unlike their macroscale counterparts due to the high surface to volume ratio and other novel physiochemical properties like color, solubility, strength, diffusivity, toxicity, magnetic, optical, thermodynamic, etc. (Rai et al., 2009; Gupta et al., 2016). Nanotechnology has brought new industrial revolution and both developed and developing countries are interested in investing more in this technology (Qureshi et al., 2012). Therefore, nanotechnology offers a wide range of opportunities for the development and application of structures, materials, or system with new properties in various areas like agriculture, food, and medicine, etc.

The rising consumer concerns about food quality and health benefits are impelling the researchers to find the way that can enhance food quality while disturbing least the nutritional value of the product. The demand of nanoparticle-based materials has been increased in the food industry as many of them contain essential elements and also found to be non-toxic (Roselli et al., 2003). They have been also found to be stable at high temperature and pressures (Sawai, 2003). Nanotechnology offers complete food solutions from food manufacturing, processing to packaging. Nanomaterials bring about a great difference not only in the food quality and safety but also in health benefits that food delivers. Many organizations, researchers, and industries are coming up with novel techniques, methods, and products that have a direct application of nanotechnology in food science (Dasgupta et al., 2015).

The applications of nanotechnology in food sector can be summarized in two main groups that are food nanostructured ingredients and food nanosensing. Food nanostructured ingredients encompass a wide area from food processing to food packaging. In food processing, theses nanostructures can be used as food additives, carriers for smart delivery of nutrients, anti-caking agents, antimicrobial agents, fillers for improving mechanical strength and durability of the packaging material, etc. whereas food nanosensing can be applied to achieve better food quality and safety evaluation (Ezhilarasi et al., 2013). In this study, we have summarized the role of nanotechnology in food science and food microbiology and also discussed some negative facts associated with this technology.

MORE DESCRIPTION:

Nanotechnology has various applications in food science, offering innovative solutions to enhance food quality, safety, and sustainability. Some significant applications include:

  1. Food Packaging: Nanotechnology enables the development of advanced packaging materials with improved barrier properties, extending the shelf life of food products. Nano-coatings can prevent moisture, gas, and light from penetrating packaging, thus reducing spoilage and preserving freshness.
  2. Food Preservation: Nano-sized antimicrobial agents can be incorporated into food packaging materials or directly applied to food surfaces to inhibit the growth of bacteria, fungi, and other pathogens, thereby extending the product’s shelf life without the need for chemical preservatives.
  3. Nutrient Delivery: Nanoencapsulation allows for the encapsulation of nutrients, vitamins, antioxidants, and other bioactive compounds at the nanoscale. This enhances their stability, solubility, and bioavailability, ensuring better absorption and utilization in the body.
  4. Food Sensing and Detection: Nanosensors can detect contaminants, toxins, and pathogens in food quickly and accurately, enabling rapid quality control and ensuring food safety throughout the supply chain. These sensors can detect minute quantities of harmful substances, reducing the risk of foodborne illnesses.
  5. Improved Taste and Texture: Nanotechnology can be used to manipulate the structure and composition of food ingredients at the molecular level, leading to improved taste, texture, and sensory attributes of food products. For example, nanostructured emulsions can enhance the creaminess and stability of dairy products.
  6. Nutritional Supplements: Nanostructured delivery systems facilitate the development of fortified foods and dietary supplements with enhanced nutritional profiles. Nanoemulsions, nanocapsules, and nanoparticle-based carriers enable the controlled release of nutrients, enabling their targeted delivery to specific tissues or organs.
  7. Food Quality and Safety Testing: Nanotechnology-based analytical techniques, such as nanoscale biosensors and imaging methods, offer sensitive and selective tools for detecting food contaminants, allergens, and adulterants. These techniques enable rapid on-site testing, reducing the need for time-consuming laboratory analysis.
  8. Smart Packaging: Nanotechnology enables the development of smart packaging systems equipped with sensors and indicators that monitor food quality parameters such as temperature, humidity, and gas composition. These intelligent packaging solutions provide real-time information about food freshness and safety to consumers and stakeholders.
  9. Environmental Sustainability: Nanotechnology can contribute to sustainable food production practices by reducing waste, energy consumption, and environmental pollution. Nano-enabled materials and processes enable the development of eco-friendly packaging, efficient delivery systems, and resource-efficient food production techniques.

Overall, nanotechnology holds great promise for revolutionizing various aspects of food science, ranging from food processing and packaging to quality control and safety assurance. However, it is essential to address potential safety concerns and regulatory challenges to ensure the responsible and ethical implementation of nanotechnology in the food industry
