From the toxicological point of view, in the last two years melamine and cyanuric acid have become matters of great interest. These substances, especially melamine, have been abused during food and feed adulteration by increasing the content of nitrogen compounds in these products. Melamine and cyanuric acid as individual substances do not pose any serious risk in terms of toxicology. From the ...

Coffee is one of the most popular beverages in the world, prepared and consumed in many different ways. Taste, aroma and composition of the coffee brew vary depending on the preparation method. Therefore, this study investigates the effect of different brewing methods on the polyphenol and methylxanthine composition and antioxidant capacity of thirteen different coffee brews. The content of tot...

The prevailing catastrophe caused by mothers in China unwittingly feeding their babies formula milk that was contaminated by a potentially toxic chemical, melamine, shows just how fragile the barriers protecting children from danger are. The epidemic has spread to neighbouring countries in southeast Asia, and melamine has been detected in formula milks (and other foods) in the USA and South Afr...

A prospective cohort study of 1,520 mothers from Zhejiang province of China was undertaken to determine the duration of breastfeeding and associated factors during the first six months postpartum. Most (95.3%) mothers had introduced complementary foods by six months, making them at risk from contaminated infant formula. The mean duration of'any breastfeeding' was greater than 180 days but only ...

BACKGROUND Melamine-contaminated milk powder was the cause of the 2008 outbreak of urolithiasis in young children and infants in China, but the prognosis of these children remains unknown. We hypothesized that urolithiasis induced by melamine-contaminated milk powder may be associated with secondary renal injury. METHODS A total of 8335 children (≤6 years old) with a history of consuming mela...

Lactoferrin is a major component of breast milk protein, constituting 10-15% of the total content. Each molecule of lactoferrin is capable of binding two atoms of iron and it has been proposed that lactoferrin is involved in iron absorption in the newborn infant. It is known that iron status of exclusively breast-fed infants usually is satisfactory to 6-9 months of age, in spite of a low iron c...

BACKGROUND Human milk contains many metabolic hormones that may influence infant growth. Milk leptin is positively associated with maternal adiposity and inversely associated with infant growth. Most research has been conducted in populations with higher leptin levels; it is not well understood how milk leptin may vary in lean populations or the associations that reduced leptin may have with in...

The increasingly common application of the near-infrared (NIR) hyperspectral imaging technique to the analysis of food powders has led to the need for optical characterization of samples. This study was aimed at exploring the feasibility of quantifying penetration depth of NIR hyperspectral imaging light for milk powder. Hyperspectral NIR reflectance images were collected for eight different mi...

A low temperature plasma ambient ionization source, coupled to a portable mass spectrometer (Mini 10.5), is used for the determination of melamine contamination in whole milk and related materials. Thermally assisted desorption and ionization of the analyte was achieved with the plasma probe. The small size, low power consumption and capability for direct sampling without pretreatment makes pla...

INTRODUCTION Exclusively breastfed infants born to obese mothers have previously been shown to gain less weight by 1-month postpartum than infants of normal-weight mothers. Our hypothesis is that human milk composition and volume may differ between obese and normal-weight mothers. OBJECTIVE To compare human milk leptin, macronutrient concentration, and volume in obese and normal-weight mother...
