Milk fat is an important food component, and plays a significant role in the economics, functional nutrition, and chemical properties of dairy products. Dairy products also contain nutritional resources and essential fatty acids (FAs). Because of the increasing demand for dairy products, milk fat is a common target in economic fraud. Specifically, milk fat is often replaced with cheaper or readily available vegetable oils or animal fats. In this study, a method for the discrimination of milk fat was developed, using FAs profiles, and triacylglycerols (TGs) profiles. A total of 11 samples were evaluated: four milk fats (MK), four vegetable oils (VG), two pork lards (PL), and one beef tallow (BT). Gas chromathgraphy analysis were performed, to monitor the FAs content and TGs composition in MK, VG, PL, and BT. The result showed that qualitative determination of the MK of samples adulterated with different vegetable oils and animal fats was possible by a visual comparision of FAs, using C14:0, C16:0, C18:1n9c, C18:0, and C18:2n6c, and of TGs, using C36, C38, C40, C50, C52, and C54 profiles. Overall, the objective of this study was to evaluate the potential of the use of FAs and TGs in the detection of adulterated milk fat, and accordingly characterize the samples by the adulterant oil source, and level of adulteration. Also, based on this preliminary investigation, the usefulness of this approach could be tested for other oils in the future.

Background: Early infant feeding is essential for children's development and future health, particularly in preventing obesity, which is the most common nutrition-related disorder in children worldwide.
Summary: Obesity, characterized by excess body fat and numerous complications, arises from a combination of genetic susceptibility and an obesogenic environment, including lifestyle behaviors related to energy balance. Eating habits start to be shaped early in life, making the introduction of solid foods a critical period.
Infants with Excessive Weight Gain while Exclusively Breastfeeding: Follow-Up at 36 Months.

Rapid weight gain in infancy is associated with an increased risk of later adiposity. Very rarely, however, exclusively breastfed infants experience excessive weight gain (EWG) during the period of exclusive breastfeeding (EBF) when breast milk is the only source of nutrition. We investigated growth and body composition at 36 months in children experiencing EWG during EBF.

Purpose Of Review: The use of body composition to assess the quality of infant growth may add valuable information to pediatric clinical care. Preterm infants have differences in their fat and muscle mass development compared with infants born at term, which may be related to their early nutritional exposures. This review focuses on recent studies examining early nutrition in preterm infants and related body composition outcomes in the newborn period and beyond.

Research Background: With the increasing consumption of food commodities, particularly rice, and the substantial volume of food imports in Indonesia, there is an increasing need to explore alternative food sources. Rice analogues emerge as a potential substitute for traditional rice, serving as a viable staple food option. The aim of this study is to investigate the effect of the composition of raw material, namely sago and corn flour, on the physicochemical properties and consumer acceptance of rice analogues.
