INTRODUCTION
Food Labeling is a science and commerce communication, which is mandatory to be declared by the manufacturers of food articles to target consumers, law enforcement authorities, supply chain authorities, food scientists, researchers and policy-makers during the intended business domestically or globally. Therefore, it is necessary for food safety and nutrition amongst the public for their informed and correct choice of food articles. Knowledge and dissemination of these communications are to be correct, empirical and validated by studies. Food labeling policy is critical to ensuring that consumers have access to accurate information about the food products they purchase.[1] Various events have shaped food labeling research and policy over the years. A few crucial events in the field of food labeling policy highlight its importance.[2] A landmark legislation, âPure Food and Drug Act-1906â, in the United States marked the beginning of federal food regulation.[3] It required accurate labeling of food and drugs and aimed to prevent adulteration and misbranding. Nutrition Labeling and Education Act (NLEA) of 1990 (NLEA) mandated standardized nutrition labeling on most packaged foods in the US, including the Nutrition Facts panel, which provides information about serving sizes, calories and nutrient content.[4] Further, with the âTrans Fat Labeling Ruleâ (2006), the US FDA required the inclusion of trans fat information on food labels, helping consumers make informed choices regarding their dietary fat intake.[5] In the US, the Food Allergen Labeling and Consumer Protection Act (FALCPA) mandated the clear labeling of major food allergens, ensuring that those with allergies could easily identify potential allergens in food products.[6] GMO Labeling (Various Years): Several countries and US states have introduced or considered regulations requiring the labeling of Genetically Modified Organisms (GMOs) in food products.[7]
Similarly, many countries have introduced front-of-package labeling systems to help consumers quickly assess the nutritional quality of food products. Examples include the âTraffic Lightâ system in the UK[8] and the âNutri-Scoreâ in some European countries.[9] In the US, the Affordable Care Act required chain restaurants and similar food retail establishments to display calorie information on menus and menu boards to inform consumers about the nutritional content of restaurant food due to the Menu Labeling Rule (2010).[10] Efforts have been made to standardize date labeling on food products, reducing consumer confusion about âsell by,â âuse by,â and âbest beforeâ dates. Under organic labeling, regulations for organic food labeling have evolved over the following several years, with many countries establishing standards for what can be labeled as âorganic.â[11] Several countries have implemented Country of Origin Labeling (COOL) requirements, mandating the disclosure of where certain foods and ingredients originate.[12] Regulations surrounding health claims on food labels have been established to ensure that such claims are substantiated and not misleading to consumers. Governments have implemented or proposed policies to include added sugar information on food labels, as excessive sugar consumption is a public health concern. These updates represent a subset of the many developments in food labeling policy. Food labeling policies continue to evolve to address emerging health and safety concerns and meet consumer demand for more transparent and informative labeling. The primary food regulations in India encompass the FSSAI (Food Safety and Standards Authority of India), the Legal Metrology Act of 2009 and the Consumer Protection Act of 2019.[13,14] There are additional food-related laws in India like AGMARK, BIS (Bureau of Indian Standards), etc., all of which have their specific guidelines and regulations, including rules for food labeling.[14]
Food labels serve as a valuable tool for consumers, providing essential information about the contents of a product and assisting in making healthier choices among processed foods. Whether itâs the front, back, or sides of a package, these labels are designed to inform us about the foodâs composition and offer guidance on better dietary decisions.
The scientometric analysis is a powerful and established method for assessing the status and progress of a particular field of study. It systematically evaluates research publications, encompassing articles, reviews, conference papers and other forms of scientific communication. By applying scientometric techniques, researchers comprehensively understand evolution of the specific area of research over time, key contributors, the most cited works, the emerging themes and paradigms. Food labeling research has evolved with societal shifts in attitudes toward health, nutrition and sustainability. In the past, food labels primarily focused on basic nutritional information. However, as consumer demands and regulations have grown more stringent, researchers and policymakers have expanded their focus to include allergen disclosure, sustainability claims and ethical labeling. The scientometric analysis conducted in this study provides a historical overview of these developments, allowing us to trace the evolution of food labeling research and its current state.
The present study employs scientometric techniques to achieve several key objectives, including the identification of research trends, contributions by different institutes and countries, mapping collaborations among institutions and countries, analyzing highly cited works and highlighting the prominent funding agencies cited in the published documents. This study aims to contribute valuable knowledge that will inform future research, policy decisions and industry practices in the ever-evolving field of food labeling.
