Milk Adulteration and Its Toxicological Effects

d newfangled Adulteration and Its Toxicological Effects initiationDespite the governing the control of reference and sale of take disclose lively for decades, deterioration of draw could non be checked. With the profit demand of take out, the deterioration of this commodity is on increasing day by day. The problem of adulteration is more than during summer and rainy seasons, when milk crosswayion in comparatively a great deal less(prenominal) than the winter season.Adulteration of a food word whitethorn be defined as making the article muddy by the addition of some of the legally prohibited substances into a more rich product or the subtraction into a more valuable comp whizznt a product to de cherish the latter or the conclave of both, with a view to subjoin the bulk or quality and to increase unlawful, excessive profit through sale of such(prenominal) a food. perpetually since the system of organized milk collection was introduced in this country, the quality o f milk received by our dairy farm industry has not been improved. The adulteration is carried out through a number of fraudulent practices, which not notwithstanding set out down the nutritional value but turn overs it unfit for human employment with cyanogenetic effects. The load milk alike leads to the production of standard dairy products resulting in economic harmes. The practice of adulteration has beseem extensive imputable to existing conditions of production and handling of milk. Various no. of tests determine the temper and extent of adulteration of milk and even adulterants.The purchasing power of some(prenominal) consumers in our country is very low. Consequently such consumers often go for the lower price of milk, even knowing about the unfortunateer quality of the same. such(prenominal) attitude of the consumers makes adulteration of milk possible to a greater extent. 1Types of adulterationThe ballparkly exercised adulterants beadd-on of water.Addition o f separated milk.Addition of thickening agents when milk id watered it becomes deficient in density and in like manner viscosity which may be restored by addition of substances like gelatin, chide sugar, starch, glucose.Partial skimming.Addition of colourizeing matter to restore color lost by skimming or diluting or to make naturally poor looking to appear rich.Unusual adulterants-of late, due to more wide diffuse use of fertilizers by farmers in India, who atomic number 18 also the primary milk producers, a few new types of adulterants like urea, ammonium sulphate etcetera have come up. 2MILK ITS COMPOSITIONmilk is an emulsion or colloid of butter flumpten up globules with in a water based fluid that contains dissolved carbohydrates and protein aggregates with minerals. take out is the secretion, practically supererogatory from colostrum, obtained by the milking of healthy udder.it re ease ups one of the sources of essential aminic acids for human nutrition. These nutri tional attributes of milk have long made it a mainstay particularly in the diet of growing children. There argon estimated to be the 8 to 10 thousand milk products made of milk available in world thus making it exceptionally assorted raw product. draw is composed of water, fat, protein, lactose, and minerals. The concentration of these products varies between cows and breeds. sum total milk solid refers specifically to fat, protein, lactose and minerals. This is to be differentiated from SNF (solid not fat), a frequently used term which describes the total solid table of sums minus fat.The nutritional as well as economic value depends upon its solid contents. The nobleer the solid content the greater the milk product yields. Cheese yield are directly relayed to milk casein content. Milk contains dozens of other types of proteins beside the caseins including enzymes. These other proteins are more water-soluble than the caseins and do not form sizabler structures. Be curtilage the proteins remain suspended in the whey left behind when the caseins coagulate into curds, they are collectively known as whey proteins.Calcium, phosphate, magnesium, sodium, potassium, citrate, and chlorine are all included as minerals and they typically occur at concentration of 540 mm. 3Composition stumble milkWater 84-90% enlarge 2-6%Protein 3-4%Lactose 4-5%Ash .1%NEED FOR bear upon OF MILKA multitude of events takes place in the process of delivering milk from the farm to the dinner table and all are designed to append the consumer with wholesome, nutritious and safe products. The production of quality milk and milk products are begins in the farms and continuous through further handling, touch and distribution.Milk processing has two primary objectivesDestruction of human pathogens through pasteurization.Keeping the quality and shelf living of the products without prodigious loss of flavor, appearance, physical and nutritive properties.Milk processing and plant proc edure seeks toPrevent further bacterial pollution of raw material.Reduce bacterial numbers in milk.Protect the sunk products from recontamination through careful handling, proper packing and storage.Pasteurization is the means whereby raw milk is rendered safe for human consumption. It is the process of heating milk to a sufficient temperature for a sufficient length of time to make it free from pathogens, and spoilage bacteria. 4TOXICOLOGICAL EFFECTS OF ADULTERANTSFORMALINFormalin is added in milk to preserve it for longer period. Formalin is very toxic. Many cases of biological variant and reproduction complication have been noted. On toxicity it fuck offs tumors formalin gravels systema nervosum centrale disorders and also irritates odorize, throat and lungs. When taken in eminent dose it attempt merchantmancer and may lead to coma.UREAUrea is generally added in the preparation of synthetic milk to raise the SNF value. say-so symptoms are burn sensation in throat and c hest cough, dyspnea, exercise-induced asthma (one case) redness, in look and come up, headache nausea, vomiting, lung damage-fibrosis, inflammation (HE11). Affected organs are respiratory system, skin, eyes, it has also used medically as an abortifacient and a skin moisturizer.ammonium SULPHATEThe presence of ammonium sulphate increases the lactometer reading. The product has low toxicity. However, the avocation points should be noted. On skin contact prolonged contact may cause some ire. On eye contact it may cause irritation. On ingestion small quantities are unlikely to cause toxic effect and large quantities flip over rise to gastro-intestinal disorders. On inhalation high dust concentration of air-borne material may cause irritation of the nose and upper respiratory tract with symptoms such as sore throat and coughing. Inhalation of some decomposition gases may cause irritation and bitter effects on the respiratory system. Some lungs effect may be delayed.HYDROGEN PEROXID EMilk is treated with different concentrations of enthalpy bleach (0.01, 0.02, 0.03, 0.04, 0.05 and 0.06 % of H2O2), along with control sample (untreated sample), for the purpose to activate Lacto peroxidase system, which destroy the bacterial population by its antibacterial effect. Lacto peroxidase (LP) system is naturally present in raw milk that prevents the bacterial multiplication due to its bacteriostatic effect. By activating the LP-system, shelf life of milk can be change magnitude for 8 to 12 hours. Lacto peroxidase (LP) system consists of three components LP, thiocyanate and hydrogen peroxide. And it is active only when all of three components are present. Lacto peroxidase catalyzes the oxidation of thiocyanate by hydrogen peroxides and generates an mean(a) product with antibacterial properties. These products have a broad range of healthful effects against bacteria, fungi and viruses.ObjectivesRaw milk preservation by use of H2O2 is done for many important purposes likeTo enhance the shelf life of milk for consumption without microbial contamination.To minimize the processing cost by heating the milk.Side Effects of Hydrogen PeroxideEye movie to dilute hydrogen peroxide may cause extreme irritation and pain, but is unlikely to cause permanent damage.Enemas of dilute hydrogen peroxide have been reported to cause serious gastrointestinal side effects. flake off contact with narrowd hydrogen peroxide can cause stark(a) burns and even gangrene.An overuse of H2O2 can cause damage to desoxyribonucleic acid cells, and prevent them from replicating, hence leading to premature aging.The use of hydrogen peroxide can cause your skin to dry out or quite a drains away the moisture content in skin, which is required to keep your skin looking young and supple.Vitiligo is a disease that is marked by the loss of skin pigment, which affects a lot of people. Studies show that it is due to the high levels of hydrogen peroxide in the blood and epidermis.It can cause irritation in gums and teeth, since H2O2 is a highly fight backive compound.Hydrogen peroxide being highly reactive can easily pass through your in any caseths enamel and react with the dentin and pulp part of your tooth.Throat soreness is another earthy side effect of hydrogen peroxide. 5SUGARThe common sugar present in milk is lactose. The fat content of the milk is more compared to the protein content. gameboard sugar like sucrose is added to the milk to increase the carbohydrate content of the milk and thus the density of milk provide be increased. So the milk can now be adulterated with water and it will not be detected during the lactometer test. Ketose sugar will react with the resorcinol to give a red colored precipitate, indicating the presence of Table sugar in milk.SIDE EFFECTS OF SUGAR carbohydrate can suppress your resistive system.Sugar eaten during pregnancy and lactation can influence brawniness draw out production in offspring, which can affect an ind ividuals qualification to exercise.Sugar can elevate glucose and insulin responses and return them to fasting levels slower in oral contraceptive users.Sugar can increase reactive type O species (ROS), which can damage cells and create from raw materials.Sugar can cause hyperactivity, anxiety, inability to concentrate and crankiness in children.Sugar can produce a significant rise in triglycerides.Sugar causes a decline in tissue elasticity and persist the more sugar you eat, the more elasticity and function you lose.Sugar reduces high-density lipoproteins (HDL).Sugar can lead to ovarian cancer.Sugar can increase fasting levels of glucose.Sugar causes copper deficiency.Sugar can make tendons more brittle.Sugar can increase the levels of glucose in the blood much higher than complex carbohydrates in a glucose tolerance test can.Sugar can cause two blood proteins albumin and lipoproteins to function less effectively, which may reduce the bodys ability to handle fat and cholester ol.Sugar can contribute to Alzheimers disease.Sugar can cause platelet adhesiveness, which causes blood clots.Sugar can cause hormonal unbalance some hormones become underactive and others become overactive.Sugar can cause free radicals and oxidative stress.Sugar increases the concentration of bile acids in corporation and bacterial enzymes in the colon, which can modify bile to produce cancer-causing compounds and colon cancer.Sugar combines with and destroys phosphatase, a digestive enzyme, which makes digestion more difficult and can annoy premenstrual syndrome (PMS).6SaltAddition of salt in milk is in the first place restored with the aim of increasing the corrected lactometer reading. All four cationic electrolytes (sodium, potassium, magnesium, and calcium) are available in unrefined salt, as are other alert minerals needed for optimal bodily function. Too much or too little salt in the diet can lead to muscle cramps, dizziness, or even an electrolyte disturbance, which can cause neurological problems.Excess salt consumption has been linked toExercise induced asthma.Heartburn.Osteoporosis.Gastric cancer is associated with high level of sodium.Hypertension.Left ventricular hypertrophy (cardiac enlargement).Duodenal ulcer. 7Vegetable FatMilk fat is the natural source of variable variety of juicy acids diversified in nature. It is separated to make the cream and sold at high prices. People separate the cream from the milk and add vegetable fat into the milk and then sell it after homogenization. Vegetable fat is unsaturated and it gets oxidized and becomes morose when exposed to air so become hepato-toxic and may cause liver cirrhosis. Small milk globules become rancid when oil and vegetable fat is being added and interesting thing is that color and consistency of the milk remains normal. 8StarchMilk contains relatively large amount of fat. Addition of carbohydrate to milk increases its solid content. There by reducing the amount of fat present in the milk. Starch is one such component that is added to adulterate milk. The test to detect starch in milk uses iodine solution, addition of which turns the milk solution to blue slow color due to the formation of starch Iodo complex, in the presence of starch.Potential symptoms are irritation of eyes, skin, mucous, membranes, rhinorrhea, cough, chest pain, dermatitis.SoapSoap is added to milk to increase the foaming of milk and thus to have thick milk. Addition of such chemicals will cause health problem especially related to jump out and kidneys. Soap can be detected by adding phenolphthalein indicator to the adulterated milk. A pink color will be observed if lash is present as the alkali will be neutralized by the acidity of the milk when phenolphthalein indicator is added. 9NeutralizersThe new Neutralizers Test manufactured by Astori Tecnica allows the immediate colorimetric determination of the presence of added neutralizers (such as NaOH, KOH, carbonates, bicarbonates, amm onia, various alkalis, etc.) in milk or cream. These prohibited substances may be added to fresh or badly preserved milk with the tricky purpose to correct its pH and acidity values to optimal ones, and so pretend the milk is impudently milked or perfectly preserved. 10REFERENCES Research Can Lead To Longer shelf Life For Dairy Products (http //www.sciencedaily.com/releases /2002/12/021223084204.htm).Sciencedaily.com. 2002-12-23.
