To detect urea content in milk powder, a nonlinear chemical fingerprint technique was developed. In our study, Belousov-Zhabotinsky oscillatory chemical reaction (B-Z) was performed using milk powder and malonic acid as main dissipative substances. The same dosage of milk powder with or without artificially added urea was introduced to “H+ + Ce4+ + 3 BrO − + malonic acid” oscillating system, re...

Heat treatment during the production of skimmed milk powder causes denaturation of proteins, thereby affecting the physicochemical properties of the skimmed milk powder. To understand the effects of heat treatment on the sensitivity of the casein micelles in skimmed milk powders, low heating type (L), normal heating type (N), high heating type (H), and super-high heating type (SH), to reaction ...

The study was undertaken to evaluate some chemical parameters of powder milk available in Mymensingh town. Powder milk samples of six different brands namely Kwality, NIDO, Diploma, Anchor, Farmland & Starship were collected from local market. Powder samples were analyzed to know the chemical (P, acidity, fat, protein, lactose, ash, moisture, solids-not-fat, total solids) characteristics. P, ac...

The microflora of milk powder consists of a wide array of microorgan­ isms of which special attention is given to Bacillus endospores. Bacillus endospores survive pasteurization and spray drying and inhabit the final powder product in the dormant state indefinitely. Once the powder is re­ constituted, endospores may germinate, and through their enzymatic ac­ tivity become detrimental to quality...

Certain aldehyde and ketone compounds can be used as indicators, at a molecular level, of the oxidized flavor of milk powder instead of sensory evaluation. This study investigated the formation of aldehyde and ketone compounds as affected by the heat-related processing and storage of milk powder. The compounds were extracted by solid phase microextraction fiber and determined using gas chromato...

Goats’ milk adulteration with cows’ milk is becoming a big problem. In the past, the urea-polyacrylamide gel electrophoresis assay with different motility of αS1-casein has been applied for the identification of cows’ milk adulteration. The detection sensitivity is 1.0%. The aim of this study was to develop a faster and more sensitive method to detect cows’ milk which may be present in adultera...

A colorimetric mixed pH dye-based indicator to real-time monitoring rancidity reaction of infant milk powder formula is described. Milk powder stored in 30, 40, and 50°C was analyzed in terms of peroxide value (PV), moisture content, volatile compounds and sensory score. In addition, moisture sorption isotherms of infant milk powder formula were assessed at various temperatures including 30, 40...

background: the presence of aflatoxin m1 (afm1) andantibiotic residues in milk and milk products is a public healthconcern. milk and milk powder have the potential forintroducing afm1 and antibiotic into human diet. in recentyears, milk powder has been used on a large scale in dairyfactories. consequently, antibiotic residues and aflatoxincontamination control in these products has gained impor...

A large-scale outbreak of food poisoning caused by consumption of skimmed milk powder contaminated with staphylococcal enterotoxin A (SEA) occurred in Japan. No viable Staphylococcus aureus was detected in the skimmed milk powder, however, sea and nuc genes of S. aureus were detected in it by PCR. The number of S. aureus in skimmed milk powder was estimated by quantitative real-time PCR.

Coconut milk was prepared by grinding coconut with water and straining through muslin cloth. To improve total solids and protein contents of coconut milk, various temperatures and pH levels of extraction water were investigated. Coconut milk prepared by grinding coconut with hot water (80C) at pH 8 contained highest solids and proteins. The coconut milk was then blended with various percentages...
