Journal of Medicinal Chemistry and Drug Discovery ISSN: 2347-9027 International peer reviewed Journal Special Issue Analytical Chemistry Teacher and Researchers Association National Convention/Seminar Issue 02, Vol. 02, pp. 610-616, 8 January 2017 Available online at www.jmcdd.org To Study The Harmful Effects Of Food Preservatives On Human Health Shazia Khanum Mirza1, U.K. Asema2 And Sayyad Sultan Kasim3. 1 -Research student , Dept of chemistry, Maulana Azad PG & Research centre, Aurangabad. 2-3 -Assist prof. Dept of chemistry,Maulana Azad college Arts sci & com.Aurangabad. ABSTRACT Food chemistry is the study of chemical processes and interactions of all biological and non- biological components. Food additives are chemicals added to foods to keep them fresh or to enhance their color, flavor or texture. They may include food colorings, flavor enhancers or a range of preservatives .The chemical added to a particular food for a particular reason during processing or storage which could affect the characteristics of the food, or become part of the food Preservatives are additives that inhibit the growth of bacteria, yeasts, and molds in foods. Additives and preservatives are used to maintain product consistency and quality, improve or maintain nutritional value, maintain palatability and wholesomeness, provide leavening(yeast), control pH, enhance flavour, or provide colour Some additives have been used for centuries; for example, preserving food by pickling (with vinegar), salting, as with bacon, preserving sweets or using sulfur dioxide as in some wines. Some preservatives are known to be harmful to the human body. Some are classified as carcinogens or cancer causing agents. Keywords : Food , Food additives, colour, flavour , texture, preservatives. -

Department of Biological Sciences, Covenant University, Ota, Nigeria *Corresponding Author; Email: [email protected]; +2348065299155 Abstract Foods usually carry a mixed population ofmicroorganisms derived from both the natural microfloro of the food plant or animo/ and those introduced during handling, processing, and storage. Salt is a widely used additive and preservative, which, influences microorganisms in different concentrations. This study aims to determine the effect of salts on food preservation and metabolic activities of food microfloro. Two food samples (row fish and raw lean meat) were investigated. Sodium chloride (NaCI), Potassium chloride {KCI} and Calcium chloride {CoCI,) were grouped into varying concentrations of2, 2.5 and 4.5% respectively. -
Potential Metabolic Effect of Sucralose Following an Oral Glucose Load in Subjects with Obesity and Normal-Weight Subjects
POTENTIAL METABOLIC EFFECT OF SUCRALOSE FOLLOWING AN ORAL GLUCOSE LOAD IN SUBJECTS WITH OBESITY AND NORMAL-WEIGHT SUBJECTS BY ALEXANDER DANIEL NICHOL THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Food Science and Human Nutrition with a concentration in Human Nutrition in the Graduate College of the University of Illinois at Urbana-Champaign, 2018 Urbana, Illinois Master’s Committee: Assistant Professor M. Yanina Pepino de Gruev, Chair Assistant Professor Megan J. Dailey Professor Emeritus John W. Erdman ABSTRACT Objective: Whether sucralose, the most commonly used non-nutritive sweetener (NNS), affects glucose metabolism in people is unclear. It has been reported that, when consumed acutely before an oral glucose tolerance test (OGTT), sucralose enhances insulinemic responses and decreases insulin sensitivity in subjects with obesity who are not regular consumers of NNS. However, studies in normal-weight adults, none of which control for use of NNS, found sucralose does not affect insulin responses to the ingestion of glucose or other carbohydrates. The objectives of the current study are to determine if those effects of sucralose can be replicated in subjects with obesity, are generalizable to normal-weight subjects when controlling for history of NNS use, and are caused merely by the sweet taste of sucralose (i.e., sham-feeding). In addition, with the aim of identifying potential mechanisms by which sucralose may decrease postprandial insulin sensitivity, we here investigated whole-body glucose kinetics by using a dual-tracer approach. Finally, we tested the hypothesis that, due to the compromised intestinal permeability associated with obesity, sucralose consumption is associated with higher plasma sucralose concentrations in people with obesity. -
Food Spoilage: Microorganisms and Their Prevention
Available online a t www.pelagiaresearchlibrary.com Pelagia Research Library Asian Journal of Plant Science and Research, 2015, 5(4):47-56 ISSN : 2249-7412 CODEN (USA): AJPSKY Food Spoilage: Microorganisms and their prevention Seema Rawat Department of Botany and Microbiology, H. N. B. Garhwal (Central) University, Srinagar, Uttarakhand, India _____________________________________________________________________________________________ ABSTRACT Food spoilage can be defined as “any sensory change (tactile, visual, olfactory or flavour)” which the consumer considers to be unacceptable. Spoilage may occur at any stage along food chain. Spoilage may arise from insect damage, physical damage, indigenous enzyme activity in the animal or plant tissue or by microbial infections. Most natural foods have a limited life. Perishable foods such as fish, meat and bread have a short life span. Other food can be kept for a considerably longer time but decomposes eventually. Enzymes can bring about destruction of polymers in some foods while chemical reactions such as oxidation and rancidity decompose others but the main single cause of food spoilage is invasion by microorganisms such as moulds, yeast and bacteria. In case of mould spoilage a furry growth covers the food and it becomes soft and often smells bad. Bacterial contamination is more dangerous because very often food does not look bad even though severely infected, it may appear quite normal. The presence of highly dangerous toxins and bacterial spores is often not detected until after an outbreak of food poisoning, laboratory examination uncovers the infecting agent. Key words: Food spoilage, Enzymes, Bacterial contamination, Food poisoning, Perishable foods. _____________________________________________________________________________________________ INTRODUCTION Food spoilage is a metabolic process that causes foods to be undesirable or unacceptable for human consumption due to changes in sensory characteristics. -

At high oxygen conditions and at low temperature, significant impairment of growth and viability of bacterial cells is found to occur as the result of free radical attack. The imposed oxidative stress leads - to an increase of intracellularly generated reactive oxygen species (mainly O2 , H2O2 and HO·), which disturbs the cellular homeostasis due to catabolic imbalance and results in growth inhibition. The so- called “free radical burst” probably is responsible for the induction of a host defence mechanism against the destructive impact of high oxygen. -

Grape and citrus processing by-products, abundant in the Mediterranean and tropical regions, respectively, are expanding and are sustainable sources of bioactive phytochemicals that can be used as natural preservatives for foods. Phytochemical composition, antioxidant, and antimicrobial properties of extracts from grape pomace (GPE), seeds (GSE), and clementine mandarin peel and pulp (MPE) grown in South Africa were analyzed. -

A decline in immune response has also been observed in people who are in contact with food additives, such as preservatives and flavours found in different foods. Objectives: The objective of the present study was to investigate the in vitro effect of food additives, such as vanillin, Monosodium L- glutamate, Sodium Benzoate, and potassium nitrate, on the production of oxygen free radicals (OFRs) by isolated human nutrophils. Methods: The study was based on the isolation of neutrophils (polymorphonuclear leukocytes; PMNs) from normal blood to determine the effects of preservatives and flavouring additives on the production of Oxygen Free Radicals by stimulated PMNs. -
