Water hardness is primarily caused by the presence of dissolved calcium and magnesium ions, carbonates, bicarbonates, chlorides and sulphates,which naturally enter water as it moves through mineral-rich soils and rocks. Calcium hardness refers to the concentration of calcium ions, usually originating from limestone, gypsum, or other calcium-containing minerals. It is the main contributor to scale […]

Iodine Value is a measure of the degree of unsaturation (double bonds) present in fats or oils. For ghee, which mainly contains saturated fatty acids, the iodine value is usually low. Testing Iodine Value helps check purity, quality, and adulteration by detecting unwanted unsaturated oils. Iodine value is determined by allowing iodine or iodine-generating reagents

Alcoholic acidity of maize/corn is a key quality parameter used to assess the freshness and storage stability of maize grains. During spoilage or fermentation, organic acids accumulate, increasing acidity. By extracting these acids with alcohol and titrating them, alcoholic acidity helps determine whether the maize is fit for food, feed, and industrial processing. Chemical &

Food packaging plays a vital role in maintaining the quality, safety, and integrity of food samples from the point of collection to laboratory testing. It helps protect the food from contamination, moisture, physical damage, and environmental factors such as temperature, light, and air. Proper packaging ensures that the sample remains in the same condition as

Carbohydrates & Energy testing in Wheat flour(atta) helps to determine its nutritional value & quality. The primary form of carbohydrate present in atta is starch, which serves as the main energy source for the human body.Overall, carbohydrates in atta not only provide energy but also play a vital role in texture formation, flavor development, and

Yeast and mold count is a horizontal method to estimate the total viable (living) yeast and mold colonies present in a food sample. It is important and widely used to assess food quality, product safety, shelf life of food samples in laboratories. Yeasts are unicellular fungi and molds are multicellular fungi that widely grows on

Sulfate is one of the major anions present in natural waters and industrial effluents. Its concentration is an important indicator of water quality since high sulfate levels can cause a bitter taste, corrosion in distribution systems, and laxative effects in humans and animals. The Conditioning Reagent Method, also known as Turbidimetric Method, is a widely

Biochemical Oxygen Demand (BOD) testing is an important water quality analysis used to measure the amount of dissolved oxygen consumed by microorganisms while decomposing organic matter in water. It indicates the degree of pollution and the presence of biodegradable waste. A higher BOD value reflects greater organic contamination, which can reduce oxygen available for aquatic

Borate testing in milk is an important quality control procedure used to detect the presence of boric acid or borax (sodium borate), which are sometimes illegally added as preservatives to extend milk’s shelf life. Although borates can prevent microbial growth and spoilage, they are toxic and harmful to human health when consumed regularly.Here we have

AdBlue (Diesel Exhaust Fluid) helps diesel vehicles run cleaner by converting harmful exhaust gases into harmless nitrogen and water vapor making it essential for modern emission control systems.Phosphate testing in Diesel Exhaust Fluid (DEF) is performed to ensure purity. Excess phosphate can damage the catalyst and reduce emission control efficiency. Phosphate reacts with ammonium molybdate
