Cooking methods affect total fatty acid composition and retention of DHA and EPA in selected fish fillets

Changes in total fatty acids in fillets of yellow stripe scad, Japanese threadfin bream, and salmon when applying different cooking methods were evaluated. All fish fillets (100 g fresh weight) were subjected to deep drying, grilling, baking in foil, and steaming. The results showed that deep frying of Japanese threadfin bream fillet significantly increased the total saturated fatty acid (955 mg/100 g) compared with the other cooking methods (499–612 mg/100 g). Baking in foil showed a significantly lower retention of total monounsaturated fatty acid in all fish fillets compared to the raw sample, especially yellowstripe scad with a total monounsaturated fatty acid content of 175 mg/100 g. Retention of DHA + EPA (mg/100 g) in yellowstripe scad fillet was found to be the highest by applying steaming method (112) compared to the raw fillet (119), followed by baking in foil (108), grilling (99), and deep frying (93). Steaming and baking in foil methods were able to retain the DHA and EPA content in the cooked fillets of all types of the studied fish compared to raw fillet. Deep frying and grilling methods showed a significant reduction of DHA and EPA contents in all fish fillets compared with steaming and baking in foil. The effect of different cooking methods was found to be significantly associated with the true retention values of DHA and EPA. In conclusion, steaming and baking in foil would be the best cooking methods for retention of DHA and EPA in yellowstripe scad fillet

Development of a mathematical model for solar module in photovoltaic systems

A mathematical model of a solar module is presented. This model takes into account solar model temperature and solar radiation. The experimental data of a solar module under natural environment condition (NEC) have been obtained to determine the model parameters. The experimental results are compared with those calculated by using a mathematical model. It shows that the mathematical model accurately simulates the current-voltage characteristics of the solar module under the NEC and therefore is suitable for photovoltaic system design and performance analysis.<br /

Infant Milk Formula with Large, Milk Phospholipid-coated Lipid Droplets Enriched in Dairy Lipids Affects Body Mass Index Trajectories and Blood Pressure at School Age:Follow-up of a Randomized Controlled Trial

Background: Human milk comprises large fat globules enveloped by a native phospholipid membrane, whereas infant formulas contain small, protein-coated lipid droplets. Previous experimental studies indicated that mimicking the architecture of human milk lipid droplets in infant milk formula (IMF) alters lipid metabolism with lasting beneficial impact on later metabolic health. Objectives: To evaluate in a follow-up (FU) study of a randomized, controlled trial whether a Concept IMF with large, milk phospholipid-coated lipid droplets enriched with dairy lipids beneficially impacts long-term body mass index (BMI in kg/m2) trajectories and blood pressure at school age. Methods: Fully formula-fed infants were randomly assigned to Concept IMF (n = 115) or Control IMF with conventional, small lipid droplets containing vegetable oils (n = 108) for the first 4 mo of age. A group of 88 breastfed infants served as a reference. During FU, anthropometrics were collected at 1, 3, 4, and 5 y of age, and blood pressure only at the last visit. Results: Compared to Control, Concept group children had consistently lower mean BMI values during FU, with the most marked difference at 1 y of age (difference in means –0.71 kg/m2, 95% confidence interval (CI): –1.13, –0.29; P = 0.001); mean values were close to the breastfed group (P &gt; 0.05). Contrary, the mean BMI values of the Control group were higher compared with the breastfed group during FU from 1 to 5 y of age (differences in means from 0.59 to 0.96 kg/m2, respectively; P &lt; 0.02). At 5 y of age, the Concept group had a lower mean diastolic and arterial blood pressure compared with the Control group; –4.3mm Hg (95% CI: –7.3, –1.3; P = 0.005) and –3.7 mm Hg (95% CI: –6.5, –0.9; P = 0.01), respectively. Conclusions: Early life feeding of an innovative IMF with large, milk phospholipid-coated lipid droplets enriched with dairy lipids results in a BMI trajectory closer to breastfed infants and a lower blood pressure at school age. This trial was registered at the Dutch Trial Register as NTR3683 and NTR5538.</p

An infant formula with large, milk phospholipid-coated lipid droplets containing a mixture of dairy and vegetable lipids supports adequate growth and is well tolerated in healthy, term infants.

BACKGROUND: Lipid droplets in human milk have a mode diameter of ∼4 μm and are surrounded by a native phospholipid-rich membrane. Current infant milk formulas (IMFs) contain small lipid droplets (mode diameter ∼0.5 μm) primarily coated by proteins. A concept IMF was developed mimicking more closely the structure and composition of human milk lipid droplets. OBJECTIVES: This randomized, controlled, double-blind equivalence trial evaluates the safety and tolerance of a concept IMF with large, milk phospholipid-coated lipid droplets (mode diameter 3-5 μm) containing vegetable and dairy lipids in healthy, term infants. METHODS: Fully formula-fed infants were enrolled up to 35 d of age and randomly assigned to 1 of 2 formulas until 17 wk of age: 1) Control IMF with small lipid droplets containing vegetable oils (n = 108); or 2) Concept IMF with large, milk phospholipid-coated lipid droplets comprised of 48% dairy lipids (n = 115). A group of 88 breastfed infants served as reference. Primary outcome was daily weight gain during intervention. Additionally, number and type of adverse events, growth, and tolerance parameters were monitored. RESULTS: Equivalence of daily weight gain was demonstrated (Concept compared with Control IMF: -1.37 g/d; 90% CI: -2.71, -0.02; equivalence margin ± 3 g/d). No relevant group differences were observed in growth, tolerance and number, severity, or relatedness of adverse events. We did observe a higher prevalence of watery stools in the Concept than in the Control IMF group between 5 and 12 wk of age (P < 0.001), closer to the stool characteristics observed in the breastfed group. CONCLUSIONS: An infant formula with large, milk phospholipid-coated lipid droplets containing dairy lipids is safe, well tolerated, and supports an adequate growth in healthy infants. This trial was registered in the Dutch Trial Register (www.trialregister.nl) as NTR3683

To evaluate in a follow-up (FU) study of a randomized, controlled trial whether a Concept IMF with large, milk phospholipid-coated lipid droplets enriched with dairy lipids beneficially impacts long-term body mass index (BMI in kg/m) trajectories and blood pressure at school age. Fully formula-fed infants were randomly assigned to Concept IMF (n = 115) or Control IMF with conventional, small lipid droplets containing vegetable oils (n = 108) for the first 4 mo of age. A group of 88 breastfed infants served as a reference. During FU, anthropometrics were collected at 1, 3, 4, and 5 y of age, and blood pressure only at the last visit. Compared to Control, Concept group children had consistently lower mean BMI values during FU, with the most marked difference at 1 y of age (difference in means -0.71 kg/m, 95% confidence interval (CI): -1.13, -0.29; P = 0.001); mean values were close to the breastfed group (P > 0.05). Contrary, the mean BMI values of the Control group were higher compared with the breastfed group during FU from 1 to 5 y of age (differences in means from 0.59 to 0.96 kg/m, respectively; P < 0.02).
