Analysis of acrylamide in food products by microchip electrophoresis with on-line multiple-preconcentration techniques
Publication date: 15 October 2016 Source:Food Chemistry, Volume 209 Author(s): Minglei Wu, Wujuan Chen, Guan Wang, Pingang He, Qingjiang Wang In this paper, a microchip electrophoresis method based on on-line multiple-preconcentration techniques combining field-amplified sample stacking and reversed-field stacking was developed for highly efficient analysis of acrylamide in food products. The related mechanism as well as important parameters governing separation and preconcentration have been investigated in order to obtain maximum resolution and sensitivity. The best separation was achieved using a 100mM bor...

Toxin levels in different variety of potatoes: Alarming contents of α-chaconine
This study measures the content of the two toxic alkaloids in 15 different varieties of potatoes considered important for a commercial use; measurements were taken immediately following the collection and after 20 days. The data show that after 20 days the α-solanine content decreases (with the exception of only four varieties), whereas the α-chaconine content increases to alarming levels.

Publication date: Available online 29 March 2016 Source:PharmaNutrition Author(s): Csaba Orbán, Kinga Katalin Horváth, Erzsébet Mák, Adrienn Lichthammer, Márta Veresné-Bálint Ketogenic diet is a dietetic approach for the treatment of refractory childhood epilepsy. In this experiment we aimed to assess the total lipid content enrichment capability of different however, less studied fats, as well as the possibilities to transfer unsaturated fatty acids and antioxidants into different foods, as these substances proved to be relevant in the mechanism of the ketogenic diet. We also determined the stability ...

Abstract
A simple and fast analytical method for the determination of fourteen perfluorinated compounds (PFCs), including three perfluoroalkylsulfonates (PFSAs), seven perfluorocarboxylic acids (PFCAs), three perfluorophosphonic acids (PFPAs) and perfluorooctanesulfonamide (PFOSA) and ten potential precursors, including four polyfluoroalkyl phosphates (PAPs), four fluorotelomer saturated acids (FTCAs) and two fluorotelomer unsaturated acids (FTUCAs) in different packaging materials was developed in the present work. In order to achieve this objective the optimization of an ultrasonic probe-assisted extract...

Gaussian Graphical Models Identify Networks of Dietary Intake in a German Adult Population [Methodology and Mathematical Modeling]
Conclusions: GGMs are a powerful exploratory method that can be used to construct dietary networks representing dietary intake patterns that reveal how foods are consumed in relation to each other. GGMs indicated an apparent major role of red meat intake in a consumption pattern in the studied population. In the future, identified networks might be transformed into pattern scores for investigating their associations with health outcomes. (Source: Journal of Nutrition)

Potato Consumption and Risk of Type 2 Diabetes: Results From Three Prospective Cohort Studies
CONCLUSIONS
Greater consumption of potatoes, especially french fries, was associated with a higher T2D risk, independent of BMI and other risk factors. Replacement of potatoes with whole grains was associated with a lower T2D risk. (Source: Diabetes Care)

Microstructural Characterization of Fried Potato Disks Using X‐Ray Micro Computed Tomography
The objective of this study was to observe the complex microstructural changes and mass transfer mechanisms in potato disks during frying. The potato disks of 1.65 mm thickness were fried at 190 °C for 0, 20, 40, 60, and 80 s. X‐ray micro‐computed tomography (CT) was used for 3‐dimensional (3D) imaging of microstructure of porous potato disks. Total porosity, pore size distribution, oil content, and air content of potato disks were calculated from resulting 3D data sets. Oil and air content measured by analysis of micro‐CT images followed trends similar to Soxtec and gas pycnometry methods, respectively. Image ana...

Screening of Potato Germplasm Resistant Against Low Temperature Sweetening
In conclusion, LAAL‐E‐Faisal and TPS‐9801 may be used for future variety improvement programs through breeding and molecular approaches.
Practical ApplicationsPotatoes are consumed in natural as well as in processed form of foods. French fries and crisps are important subdivisions of the processing industry and denote more than 70% of the potato processing industries. Potatoes are mandatory for use throughout year, however, generating fresh potatoes all the way through the year is unrealistic and long term storage is needed. Presently cold‐induced sweetening (CIS) is considered as one of the serious issue in potato...

Effect of Initial Headspace O2 Level on the Growth and Volatile Metabolite Production of Leuconostoc Mesenteriodes and the Microbial and Sensorial Quality of Modified Atmosphere Packaged Par‐Fried French Fries
This study evaluated the effect of residual O2 level (0% to 5%) on microbial growth and volatile metabolite production on par‐fried French fries packaged in a modified atmosphere with 60% CO2 (rest N2) at 4 °C. The results obtained showed that the initial headspace (IH) O2 level had an effect on growth of Leuconostoc mesenteroides on French fry simulation agar, whereby growth was slightly faster under 5% O2. In terms of quantity, ethanol, 2‐methyl‐1‐propanol, and dimethyl disulphide were the most significant volatile metabolites produced by L. mesenteroides. The production of ethanol by L. mesenteroides was highes...

Nutrient Intakes and Vegetable and White Potato Consumption by Children Aged 1 to 3 Years
We examined average nutrient intakes as well as total vegetable and white potato (WP) consumption among children aged 1–3 y using day 1 dietary data from the NHANES 2009–2012 and the Food Patterns Equivalents Database 2009–2012. Appropriate survey weights were used to calculate average daily consumption of total vegetables and WPs, which included French-fried potatoes and chips, for boys and girls aged 1–3 y. We calculated mean intakes of selected nutrients of concern, including vitamin D, potassium, dietary fiber (DF), and calcium. We also examined intakes of selected nutrients by major food group....

Dietary Patterns in Men and Women are Simultaneously Determinants of Altered Glucose Metabolism and Bone Metabolism
We hypothesized that diet would have direct effects on glucose metabolism with direct and indirect effects on bone metabolism in a cohort of Canadian adults. We assessed dietary patterns [Prudent (fruit, vegetables, whole grains, fish, and legumes) and Western (soft drinks, potato chips, French fries, meats, and desserts)] from a semi-quantitative food frequency questionnaire. We used fasting blood samples to measure glucose, insulin, homeostatic model assessment insulin resistance (HOMA-IR), 25-hydroxyvitamin D (25OHD), parathyroid hormone (PTH), bone-specific alkaline phosphatase (BAP, a bone formation marker), and serum...

Mediterranean and western dietary patterns are related to markers of testicular function among healthy men
This study was carried out on healthy and young men, so it is difficult to predict whether and how the observed differences in semen quality translate into reproductive success for men in couples trying to conceive. These results suggest that traditional Mediterranean diets may have a positive impact on male reproductive potential.
