Abstract
Title: Effect of Soya Flour, Carrageenan and Glyceryl Monostearate as Egg Replacer on Cake Quality
Najjar, I and Setarehnejad, A.rnCardiff School of Health Sciences, Cardiff Metropolitan University, Western Avenue, Cardiff CF5 2YB, UK.
A new formula of Soya flour (SF), Carrageenan (CG) and Glyceryl Monostearate (GMS) has been proposed to replace eggs in Madeira cake. The effect of the new formula was investigated by replacing egg at 25%, 50%, 75% and 100% with additional water, trialled against the standard cake containing 100% egg and no SF, CG or GMS. The quality characteristic of cakes were analysed by Volscan, Texture Analyser and bake loss to measure the volume, texture of the fresh and old cake and water loss during baking respectively.
Results showed that an increase in egg replacement caused a decrease in cake volume, specific volume and height. Volume and specific volume were the most dependant cake properties and cake with 25% egg replacement showed no significant difference (p<0.05) to standard cake in terms of volume. All cake samples showed similar texture in day one after baking compared to the standard cake. Ambient storage for a week led to a significant increase (p<0.05) in firmness of all experimental samples compare to standard cake. However, there was an inverse relationship between increasing levels of egg replacer and the firmness, which could be attributed to the effects of the egg replacers combining with the additional water. Finally, by increasing the amount of egg replacer at levels over 50% bake loss increased significantly (p<0.05), which could be due to differences in the bonding of water within the cake batter during baking.

Abstract
Title: Evaluation of nitrate, nitrite and saponins contents, total antioxidant potential, antioxidant capacity and activity in different products of beetroot: cereal bar, juice and chips. Name: Diego S Baião1, FabrÃcio de Oliveira Silva2, Daniel Perrone2, Eduardo Mere Del Aguila1, Vânia M Flosi Paschoalin1.1 Advanced Analysis in Biochemistry and Molecular Biology Laboratory, Chemistry Institute, Federal University of Rio de Janeiro, 21941-909, Rio de Janeiro, Brazil.2 Nutritional Biochemistry and Food Laboratory, Chemistry Institute, Federal University of Rio de Janeiro, 21941-909, Rio de Janeiro, Brazil.The beetroots of Beta vulgaris L. species is considered NO3- dietary and antioxidants source. However, the amount of these nutrients varies in relation to the administration form. This study aimed to develop a beetroot cereal bar (BB) and compare the NO3-, NO2- and saponins contents; potential, capacity and antioxidant activity to beetroot juice (BJ) and chips (BC). All ingredients used in the BJ, BC and BB formulations were obtained from the market from Rio de Janeiro, Brazil. The NO3-, NO2- contents and the total antioxidant potential (TAP) were analyzed by high-performance liquid chromatography. Saponins quantification was performed using spectrophotometry. The assessment of antioxidant capacity and activity was performed by the ferric reducing ability of plasma (FRAP), trolox equivalent antioxidant capacity (TEAC), oxygen radical antioxidant capacity (ORAC), 2.2-diphenyl-1-picrylhydrazyl radical scavenging assay (DPPH) and lipid peroxidation methods, respectively. BB showed the highest NO3- (16.6±0.1 mmol/100 g) and saponins (8648.3±1.85 mg/100g) contents when compared to BJ and BC. Significantly higher values in the antioxidant capacity analysis were observed in BB when compared with BJ and BC. BB also showed an ability to inhibit lipid peroxidation (86.0%) significantly higher than BJ (54.3%), BC (65.0%), butylated hydroxyanisole (BHA, 76.5%), α-tocoferol (34.3%) and similar to butylated hydroxytoluene (BHT, 86.4%) standards. All beetroot administration forms showed a high TAP. In conclusion, a new nutritional approach, BB, showed to have the highest contents of nutrients, potential, activity and total antioxidant capacity, these characteristics are important to improve the vascular health, endothelial function and exercise performance.

The interest of the athletic population in sports nutrition is increasing. Several studies have been conducted to investigate if dietary NO3- can improve exercise performance by reducing maximum volume of oxygen (VO2peak). The main objective of study was to investigate changes in biochemical and metabolic parameters to aerobic exercise using beetroot nutritional gel. In a randomized, double blind, controlled placebo, crossover design study, 25 recreational healthy runners consumed 100 g oral doses of either the beetroot nutritional gel (BG, 9.92±1.97 mmol of NO3-) or a placebo apple nutritional gel (PLA, 0.33±0.15 mmol of NO3-) and completed a continuous run exercise test on a treadmill, involving stage in warm-up at 40%, moderate intensity at 90% of the gas exchange threshold I (GET I) and severe intensity to volitional fatigue at 70% of the difference between GET I and VO2peak. Urinary NO3- and NO2- concentration (baseline: 0.306±0.342 and 0.0008±0.001 mmol/ mmol creatinine, respectively) increased signiï¬cantly 60 min after BG ingestion and immediately after exercise. BG did not promote significant differences in the VO2peak of moderate intensity (2.89±0.78 vs 2.85±0.65 l/min), severe intensity (4.00±0.95 vs 3.93±0.84 l/min) and time to fatigue (390.90±158.50 vs 395.4±179.60 sec) when compared with PLA supplementation, respectively. Systolic and diastolic blood pressure of the BG and PLA treatments did not differ significantly in any of the analyzed times. A single dose of BG gel, promoted higher excretion of NO metabolites, but did not enhance the physical performance of recreational athletes in an aerobic submaximal exercise

Abstract
Title: Modeling of Water Absorption of Cold Plasma Treated Six Chickpea cultivars (Cicer arientinum L.) using Peleg’s EquationF.L.Pathan1, R.R. Deshmukh2 and U.S. Annapure1*1Food Engineering and Technology Department, Institute of Chemical Technology, N.P Marg, Matunga, Mumbai (E), 400019.2Department of Physics, Institute of Chemical Technology, N.P Marg, Matunga, Mumbai (E), 400019. Application of the Peleg model was investigated for predicting the water absorption of six chickpea cultivars (Kripa, Virat, Vishal, Vijay, Digvijay, Rajas) during soaking at ambient temperature with cold plasma treatment (40, 50 and 60 V) each with an exposure time 10, 15, 20 minutes and without plasma treatment in distilled water. Cold plasma treatment was found to affect the rate of water absorption of chickpea cultivars and there was no effect of plasma treatment, voltage and treatment period on water absorption capacity of chickpea cultivars. K1 (Peleg rate constant) decreased from 22.7 x 10-3 to 10 x 10-3 (h % -1) for Kripa, from 7.8 x 10-3 to 4.3 x 10-3 (h % -1) for Virat, from 30 x 10-3 to 12.5 x 10-3 (h % -1) for Vishal, from 29.3 x 10-3 to 12.7 x 10-3 (h % -1) for Vijay, from 29.4 x 10-3 to 4.9 x 10-3 (h % -1) for Digvijay, from 32.4 x 10-3 to 10.8 x 10-3 (h % 1) for Rajas with increase in voltage and exposure time of plasma treatment. K2 (Peleg capacity constant) randomly increased from 9.2 x 10-3 to 11.4 x 10-3 (% -1) for Kripa, from10.2 x 10-3 to 11.8 x 10-3 (% -1) for Virat, from 9.3 x 10-3 to 11.3 x 10-3 (% -1) for Vishal, from10.8 x 10-3 to 11.3 x 10-3 (% -1) for Vijay, from10.6 x 10-3 to 12 x 10-3 (% -1) for Digvijay, from10.4 x 10-3 to 11.7 x 10-3 (% -1) for Rajas with increase in voltage and exposure time of plasma treatment. Peleg model was successfully fitted to correlate water absorption of chickpea cultivars. The model fit resulted in R2 ≥ 0.9993 for Virat, R2 ≥ 0.9963 for Rajas, R2 ≥ 0.9955 for Digvijay, R2 ≥ 0.9950 for Vijay, R2 ≥ 0.9941 for Kripa, and R2 ≥ 0.9913 for Vishal with soaking time and cold plasma treatment.
