Milk Composition Analysis_ Everything You Need to Know About Purity

1. Milk Composition Analysis: Everything You Need to Know About Purity! Milk consumption has increased worldwide in recent years. It has been preferred among dairy products for its nutrition-rich composition and other health benefits. Milk Composition: Milk is an essential source of nutrients, dietary energy, fat and high-quality proteins. It contributes significantly to nutrient intakes such as calcium, selenium, magnesium, vitamin B12, riboflavin and pantothenic acid. Different aspects affect the milk components, such as the dairy animal species, its breed, diet, age, and the stage of lactation. The colour, composition and flavour of the milk depends on the farming system, physical environment, and season. These animals include cow, buffalo, camel, goat, sheep, donkey, Yak and Equine. Water is the highest constituent of milk. The percentage of water in milk ranges from 83% in Yaks to 91% in donkeys. www.agnext.com contact@agnext.com +91 9700720005

2. India is the largest milk producer and cow milk consumer. Cow milk contains 3-4% of the solid content, whereas buffalo milk is high in fat content. The protein in cow milk is about 3.5% but about a 2:1 fat-to-protein ratio in buffalo milk. Likewise, the components vary in other animals. Milk Adulteration: The reduced quality of milk and dairy products is a rising concern for consumers. The processed milk is generally found contaminated or adulterated than the raw milk. Milk contamination is when any substance gets added to the milk, such as environmental contaminations and improper handling practices, unintentionally that reduces its quality. Milk adulteration is the deliberate practice of degrading the milk quality for profit. It can result in dangerous health hazards. The second most adulterated food item worldwide is milk powder. The common adulterants are vegetable protein, urea, detergents, hydrogen peroxide, ammonium sulphate, caustic soda, formalin, boric acid, benzoic acid, salicylic acid, sugar, melamine and neutralisers. These parameters are added to increase milk quality but can have harmful health results to consumers. Milk quality is checked by common factors like fat, SNF (Solid-Not-Fat) percentage, freezing point and protein content. Adulterants are added to adjust these www.agnext.com contact@agnext.com +91 9700720005

There is a limit set by the FSSAI (Food Safety and Standards Authority of India) under Act 2006 and PFA (Prevention of Food Adulteration) RUles 1955 on adding urea to the milk which is 70mg/100ml. FSSAI Survey: FSSASI conducted a survey on 6,432 milk samples from 1103 towns/ cities in India. Different types of milk samples were collected from organised and non-organised milk distributors, including processors, retailers, local dairy farms, milk mandis and milk vendors. On the spot, testing the critical milk quality and safety was carried out, which missed the account of adulterants and contaminations. Portable and rapid AI-based solutions such as Qualix can do a quick quality test for milk. Out of 6,432 samples, twelve were adulterated, organised roughly in which six samples included either hydrogen peroxide, detergents, urea or neutralisers. Among these twelve samples, nine were from Telangana, two from Madhya Pradesh and one from Kerala. 5.7% of the samples, that is, 368 samples, had the presence of Aflatoxin M1 beyond permissible limits. The samples from 22 states contain the residues of Aflatoxin M1, in which Tamilnadu (15.97% samples), Delhi (14.5% samples), and Kerala (19.78% samples) are the top three states. In this survey, 1.2% of samples had antibiotics residues above the permissible limit, in which Madhya Pradesh, Maharashtra and Uttarpradesh had the most antibiotics residues. www.agnext.com contact@agnext.com +91 9700720005

4. FSSAI released the full report of the survey in the ‘National Milk Safety and Quality Survey 2018’. FSSAI survey results show that milk is mainly safe to consume as 93% of the samples were safe for consumption. Though that is true, about 41% of samples have one of another quality parameter issue. Both processed and raw milk samples had either low fat or SNF or both. AgNext rapid milk composition & quality assessment solution Qualix provides a seamless experience to all stakeholders across the supply chain. It uses the image processing algorithm that has the ability to assess the milk quality by calculating % defects in each lot and analysing all chemical properties including moisture content in just 30 seconds.
