Food additive safety

as 'GRAS' (Generally RecognizedAs Safe) under sections 201(s) and 409 of the Federal Food, Drug, and Cosmetic Act [5] ,

Food is a very common source of contaminants exposure to humans and animals. An unknown number of naturally occurring contaminants find their way into food. Among them endocrine disruptors, heavy metals, acrylamide, hydroxymethylfurfural, polycyclic aromatic hydrocarbons, N-nitroso compounds, aromatic amines, amides and nitrosamines, dioxins, furans, 4(5)-Methylimidazole, trans fats, food additives, mycotoxins, and agrochemicals have concerned international regulatory bodies. The purpose of the present chapter is to give the existing and emerging scientific and regulatory landscape, regarding the aforementioned food contaminants.

Majority of consumer goods are required to be presented with good aesthetics in order to improve acceptability in terms of colours and in some instances taste. When related to food, beverages and drug products, additives are usually added to mask un-inviting colours, obscure offensive odours and increase taste. Food additives therefore include colourants, sweeteners, preservatives and anti-caking agents. Admissible daily intake limits are often recommended for these additives. Being food products, the amount consumed over time may be subject to individual preferences and thus negating the desire to regulate and control the amount consumed cumulatively. There have been several concerns about the safety of food additives and several batteries of tests, and reports are available in literature. This review attempted to give an update on reports that have surfaced in literature over recent past on the use and safety of food colours and other additives. Some safety concerns have been related to three determinations; cytotoxicity, genotoxicity and induction or potential of inducing mutagenicity. In order to accomplish these targeted evaluations, several tests have been prescribed by International conference on harmonization (ICH), organization for economic co-operation and development (OECD) and European food safety authority (EFSA). It is observed that no single test can give a full proof of safety of these food colours and additives, hence minimal tests are recommended to be carried out in order to guarantee safety of these products. Survey of literature, revealed that once some approved additives or colours become a subject of safety concerns, comprehensive evaluations are carried out by researchers and these have often led to the de-classification of some hitherto reported agents as being non-genotoxic or non-carcinogenic. The declassifications of some food colors and additives as human carcinogens are regularly done following the comprehensive evaluation of results of mutagenicity and genotoxicity tests in vitro and some in vivo tests in mammalian tissues and whole animals. However, such declassifications are often done with caution and the implication is that regular and more comprehensive tests must be carried out. In addition, the requirements of testing for chronic exposures to this and other agents must be emphasized to prevent occurrence of subtle yet terrible side effects resulting from consuming sub-toxic doses of the additives over time.   Key words: Food colour, food additive, cytotoxicity, genotoxicity, mutagenicity, safety concerns.

Additives in Dairy Foods: Safety

Background: Food additives and preservatives are integral components of the modern food industry, serving essential functions such as enhancing organoleptic properties, extending the shelf life of products, and facilitating food processing. However, as these substances play a crucial role in food production, concerns have emerged regarding their potential toxicity and effects on human health. Methods: A comprehensive literature review was conducted exploring the sources, including scientific journals on PubMed, Scopus, government publications, and websites. The article reviews existing literature and explores the latest findings in the field, shedding light on the multifaceted aspects of food additives and preservatives. It outlines the various functions these substances serve and their significance in contemporary food production, emphasizing their role in optimizing the consumer experience and food supply chain efficiency. Discussion: Numerous studies have explored the potential adverse effects of food preservatives and additives, shedding light on their impact. Striking a balance between reaping the benefits of these substances and mitigating their potential risks remains an ongoing challenge, necessitating ongoing research and oversight. This research article provides an in-depth analysis of the toxicology of food additives and food preservatives, examining their safety, regulations, and potential health impacts. It highlights the need for a comprehensive evaluation of these substances to ensure the safety of the food supply. Natural food preservatives and food additives would be better options rather than opting for synthetic and chemical forms. Conclusion: The use of natural preservatives offers a safer and more sustainable approach to food preservation, addressing consumer concerns about synthetic preservatives and promoting the production of healthier and more environmentally friendly food products.

A food additive is any substance that is deliberately added to foods to yield specific desirable effects suchas preservation and organoleptic attributes. These conferred attributes are crucial in the marketability,acceptability, aesthetics, shelf life and value enhancement of foods. Food additives have been in use bymankind since antiquity. The Egyptians coloured food with saffron, while the Romans added alum(potassium aluminum sulfate) to whiten it. Interestingly, in the 19th century, bakers in England used alumto make bread whiter and bulkier. The Indians used spices (curries) in food preservation and traded in thesame with other continents, thus resulting in the renowned inbound caravans from Europe. Salting was soeffective and highly valued to the extent of being applied as ‘payment/wages’ among the Romans.Actually, the word ‘salary’ bears its etymology (Roman, ‘sal’) form this practice. The deliberate use ofsalt to preserve fish and meat, through dehydration was commonly used in diverse cultures. Traditionalmethods for food preservation include pickling with vinegar, salting, smoking, sugaring andalcoholization.

Purpose: This study aimed to develop a four-hour food additive education program for elementary school students to provide them with accurate information on food additives.Methods: A survey was conducted among 133 elementary school students living in Gyeonggi Province to identify the level of food additive awareness.A four-hour food additive education program and educational materials (PPT, activity sheets, and teacher guidelines) were developed based on the results of the food additive awareness survey.The developed educational programs were based on the Theoretical Model of Stages of Behavior Change.An elementary school nutrition teacher conducted a pilot education for 83 elementary school students to evaluate the feasibility of the developed education program.A survey was conducted to evaluate the effectiveness and satisfaction of the pilot education program. Results:The results of the Food Additive Awareness Survey showed that only 42.1% of people were aware of food additives; 46.3% wanted to know more about food additives, and 54.3% required food additive education.Food coloring (44.7%) and artificial sweeteners (18.7%) were the most common food additives of interest.What they wanted to know about food additives was the safety of food additives (36.8%) and the role and function of food additives (20.3%).After the pilot training on food additives, the level of awareness of food additives was improved significantly, and the percentage of participants who recognized the need for food additive education and promotion increased.According to the satisfaction survey of the food additives education, the interest, understanding, real-life application, learning method, and content amount were approximately 90%. Conclusion:The educational program developed through this study will change the negative perceptions of food additives in elementary school students to a positive one.It will do so by helping nutrition educators educate students on this important subject.

The US food supply is increasingly associated with diet-related diseases, toxicity, cancer, and other health harms. These public health concerns are partly attributable to a loophole in federal law. The Food and Drug Administration (FDA) evaluates the premarket safety of ingredients regulated as food additives but allows the food industry to self-regulate and determine which substances to classify as generally recognized as safe (GRAS) based on undisclosed data and conclusions that the FDA never sees. Furthermore, the FDA lacks a formal approach for reviewing food additives and GRAS substances already found in the food supply. Substances in the food supply thus include innocuous ingredients (e.g., black pepper), those that are harmful at high levels (e.g., salt), those that are of questionable safety (e.g., potassium bromate), and those that are unknown to the FDA and the public. A recent court decision codified these gaps in the FDA's current approach, leaving states to try to fill the regulatory void. The FDA and Congress should consider several policy options to ensure that the FDA is meeting its mission to ensure a safe food supply.

This article highlights the analysis of available data about the impact of food additives on a human body. We specified the meaning of the term "food additives", paid attention to the history of discovering and applying food additives, described the differences between natural and synthetic food additives. According to the literature, most food additives used in modern food industry can be considered quite safe. The safety of food additives is determined on the basis of extensive comparative studies, and the use of food additives is prohibited unless they have been tested and approved by the relevant authorities. But, with the development of analytical methods, the emergence of new experimental data, the question of the possible negative impacts of one or another additive on individual organs and systems of the human body can be reconsidered. In particular, certain food additives that were previously considered harmless, for example E 240, E 121, are now recognized as very dangerous and prohibited for use. It has been proven that food supplements that are harmless to one person can have a negative effect on another. Therefore, it is recommended to limit the use of food additives for children, the elderly and people prone to allergic reactions. The article describes in detail the results of experimental studies about the negative impact of specific additives, in particular ponceau 4R, sodium nitrite and monosodium glutamate on individual internal organs. Attention is focused on the group of food additives such as nitrogen compounds, which due to the biotransformation can result in the nitrite formation. An excess of the latter, in turn, according to some researchers, can provoke the development of malignant tumours in various organs, primarily in the terminal parts of the colon. Thus, the impact of various combinations of food additives on the morpho-functional state of the internal organs requires further detailed research.

This study assessed the perceptions of Kentucky consumers regarding the safety of the nation's food supply. Data were collected through a telephone survey of 728 respondents. Overall, most consumers were very or somewhat confident in the nation's food supply. Significant differences were noted among consumers based on age, gender and household income. The most likely locations for food safety problems were identified as food processing plants, followed by restaurants. Respondents that were most confident in the nation's food supply believed food poisoning occurred less frequently than those who were not confident in the food supply. Those consumers who were very confident and somewhat confident in the food supply had a significantly different perception of health risks in food from germs, pesticide residues and preservatives than those who had no confidence in the food supply. Respondents with someone in the household working in the foodservice industry were not significantly different in their confidence of the nation's food supply, or in their opinion of where food safety problems occur, than those who did not. Implications for the foodservice and hospitality industry are discussed.
