BACKGROUND: The introduction of starch into an infant's diet is an important milestone in the feeding journey. Intestinal maturity and the presence of digestive enzymes are necessary for the physiologic breakdown of starch and other complementary foods. However, little is known about the consumption patterns of starch containing foods during complementary feeding. METHOD: The 2008 Feeding Infants and Toddlers Study (FITS) is a cross-sectional 24-hour dietary intake survey of a nationally representative sample of infants, toddlers, and preschoolers from birth to 48 months of age...

Sweet potato (Ipomoea batatas (L.) Lam.) is one of the most important root crops in the world. Initial formation and development of storage roots (SRs) are key factors affecting its yields. In order to study the molecular mechanism and regulatory networks of the SRs development process, we have analyzed root transcriptomes between the high and low starch content sweet potato accessions at three different developmental stages. In this study, we assembled 46,840 unigenes using Illumina paired-end sequencing reads and identified differentially expressed genes (DEGs) between two accessions...

Sucrose and its constituent components, glucose and fructose, are major determinants of sweetness in fruits and cooking quality in plant storage organs, such as potato tubers. Accurate monitoring of these sugars provides a predictive assessment of plant product quality. High Performance Liquid Chromatography (HPLC) coupled to a variety of detectors has been the method of choice for selective detection and quantitation of sugars in plant tissues. However, sugar extraction can be time-consuming to obtain a clean and concentrated sample suitable for accurate quantitation...

Sucrose non-fermenting-1-related protein kinase-1 (SnRK1) is an essential energy-sensing regulator and plays a key role in the global control of carbohydrate metabolism. The SnRK1 gene has been found to increase starch accumulation in several plant species. However, its roles in improving starch quality have not been reported to date. In the present study, we found that the IbSnRK1 gene was highly expressed in the storage roots of sweet potato and strongly induced by exgenous sucrose. Its expression followed the circandian rhythm...

Human exposure to trace elements has been a large concern due to the potential health issues. Accordingly, this study aimed to compare the concentrations of arsenic, copper, and zinc in the edible parts of vegetables grown in a mining-agricultural area and in an exclusively agricultural area and to compare the potential human health risks of consuming vegetables from both areas. The consumption habits of the studied population were extracted from the 2010 National Alimentary Survey of Chile. In most cases, the concentrations of trace elements in the edible tissues of vegetables (lettuce, spinach, garlic, onion, carrot, potato, sweet corn, and tomato) were higher in the mining-agricultural area than those in the control area...

Motivation: Polyploid species carry more than two copies of each chromosome, a condition found in many of the world's most important crops. Genetic mapping in polyploids is more complex than in diploid species, resulting in a lack of available software tools. These are needed if we are to realise all the opportunities offered by modern genotyping platforms for genetic research and breeding in polyploid crops. Results: polymapR is an R package for genetic linkage analysis and integrated genetic map construction from bi-parental populations of outcrossing autopolyploids...

Nutrition is critically important in the first 1000 days, and while most American babies are fed commercial baby foods, there is little or no evidence from nationally representative data to understand the implications of such consumption. We used 24-hour dietary recall data for 505 infants from The Feeding Infants and Toddlers Study to describe food consumption patterns and micronutrient density of complementary foods consumed by infants fed commercially prepared baby food fruit, vegetables, and dinners and compared with those eaten by nonconsumers of these products...

Jing Li, Fayin Ye, Lin Lei, Guohua Zhao
The perishable character of moist food products demands packages with antimicrobial activity and water resistance. Oregano essential oil (OEO) and starch octenylsuccination were first jointly applied to formulate antimicrobial and water-resistant sweet potato starch films. The results showed that octenylsuccination powerfully retarded the coalescence of oil droplets in film casting process and favoured their homogeneity in the dried films. OEO incorporation dose-dependently conferred antimicrobial activity upon the films, which was further enhanced by octenylsuccination to some degree...

The granules of sweet potato starch were size-fractionated into three portions with significantly different median diameters (D50) of 6.67 (small-sized), 11.54 (medium-sized) and 16.96 µm (large-sized), respectively. Each portion was hydrophobized at the mass-based degrees of substitution (DSm) of approximately 0.0095 (low), 0.0160 (medium) and 0.0230 (high). The Pickering emulsion stabilizing capacities of modified granules were tested, and the resultant emulsions were characterized. The joint effects of granule size and DSm on emulsifying capacity (EC) were investigated by response surface methodology...

Asian scalp hair fibers were made thin by treatment with papain or sliced along the longitudinal axis or randomly cut by mechanical means. Optical microscopic observations of the resulting specimens indicated that (i) the medulla (M) consisted of two types of the M-surrounding cells which were linearly linked one another to form a tubular structure running through the fiber and (ii) the drum-shaped vesicles containing small proteinous granules were neatly or sparsely stored within the tube. On the other hand, H+ and OH- ions were able to move spontaneously from one end to another through the M tube...

Cosmetics, such as lipstick, can affect an individual's perception of attractiveness and morale. Consumer concern with the safety of synthetic colorants has made the need for alternative natural color sources increasingly urgent. Our goal was to evaluate the feasibility of anthocyanin (ACN) extracts as colorants in lipstick formulations. Lipstick formulations were colored with ACN-rich materials. Accelerated environmental testing typical of the cosmetic industry were used: incubation at 20°, 37°, and 45°C for 12 weeks and temperature abuse cycles between 20°/37°C or -20°/20°C...
