Analysis Of Total Acidity Toward Bacterial And Endophytic Fungi Profile Dur-Ing Black Garlic Processing From Garlic (Allium Sativum L.) And Shallot (Allium Ascalonicum L.), Ayu Rahmania Lestari, Surjani Wonorahardjo, Suharti Suharti
Analysis Of Total Acidity Toward Bacterial And Endophytic Fungi Profile Dur-Ing Black Garlic Processing From Garlic (Allium Sativum L.) And Shallot (Allium Ascalonicum L.), Ayu Rahmania Lestari, Surjani Wonorahardjo, Suharti Suharti
Makara Journal of Science
Black garlic or shallot are products of processed garlic and shallots obtained through a heating process conducted over a certain period. Black garlic/shallots have a mild aroma with a sweet and sour taste. The heating process causes chemical compound transition in the garlic, including acidity. In addition to the chemical process, the garlic’s color and component changes are due to the role of microorganisms during black garlic processing. However, the presence and function of such microorganisms have not been identified. Therefore, this research explores the black garlic’s microorganisms, their role in black garlic processing, and their relation to the total …
Postharvest Salicylic Acid And Melatonin Dipping Delay Ripening And Improve Quality Of ‘Sensation’ Mangoes, Mohamed A. Awad, Adel D. Al-Qurashi
Postharvest Salicylic Acid And Melatonin Dipping Delay Ripening And Improve Quality Of ‘Sensation’ Mangoes, Mohamed A. Awad, Adel D. Al-Qurashi
The Philippine Agricultural Scientist
Freshly harvested mature-green ‘Sensation’ mangoes were dipped for 10 min in 2 mM salicylic acid (SA) and 0.2 mM melatonin (MT) alone or in combination and stored at 23±1°C and 60–70%RH. SA or MT delayed ripening measured as higher green peel color (lower a* values), firmness, titratable acidity (TA) and membrane stability index (MSI) and lower weight loss, total soluble solids (TSS), TSS/TA ratio and hydrolytic enzyme activities (polygalacturonase, xylanase and α-amylase) compared to that of untreated fruit. Total phenolic content (TPC) in peel of treated fruit increased with fluctuations during ripening and was higher than the control. In pulp, …
Evaluation Of The Inactivation Kinetics Of Cronobacter Sakazakii In Infant Formula Treated By Radio Frequency Dielectric Heating And Uvc Light [Research Note], Yun Deng, Yuwei Wu, Yuanrong Zheng, Danfeng Wang, Zhenmin Liu
Evaluation Of The Inactivation Kinetics Of Cronobacter Sakazakii In Infant Formula Treated By Radio Frequency Dielectric Heating And Uvc Light [Research Note], Yun Deng, Yuwei Wu, Yuanrong Zheng, Danfeng Wang, Zhenmin Liu
The Philippine Agricultural Scientist
We studied the inactivation kinetics of Cronobacter sakazakii (CS) in infant formula subjected to radio frequency dielectric heating (RF) alone or sequential RF-UVC irradiation for 30 min. We used one linear model and two nonlinear models to fit the data and compared the results. Our findings revealed that CS was more susceptible to the combined treatment than to RF alone at the same temperature and that inactivation rate increased with increasing temperature. The sequential RF (90°C, 5 min) - UVC (25 min) treatment was the most effective at inactivating CS. The survival curves of CS were non-linear. …
Novel Uplc-Ms/Ms Method For Standardization Of Niazimicin Content In Edible Seeds And Leaves Of Moringa Oleifera Lam., Eman M. Abdelsayed, Amira Abdel Motaal, Rasha S. Hanafi
Novel Uplc-Ms/Ms Method For Standardization Of Niazimicin Content In Edible Seeds And Leaves Of Moringa Oleifera Lam., Eman M. Abdelsayed, Amira Abdel Motaal, Rasha S. Hanafi
Journal of Food and Drug Analysis
Moringa oleifera (MO) is a highly nutritious plant, whose leaves and seed pods are consumed in Africa, Asia, sub-Himalayan regions and South America. A novel ultra-high performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method for the standardization of the bioactive thiocarbamate compound from MO, niazimicin (NZ) in seeds and leaves, is developed, optimized and validated according to the International Conference on Harmonization (ICH) guidelines, using desipramine as the internal standard. Multiple reaction monitoring detection of transitions 358.05>106.86 and 266.38 > 193.04 with collision energy of 25V and 40V, respectively were used. A gradient was optimized at 35-55%B …
Three-Way Analysis-Based Ph-Uv-Vis Spectroscopy For Quantifying Allura Red In An Energy Drink And Determining Colorant's Pka, Erdal Dinç Prof., Nazangül Ünal, Zehra Ceren Ertekin
Three-Way Analysis-Based Ph-Uv-Vis Spectroscopy For Quantifying Allura Red In An Energy Drink And Determining Colorant's Pka, Erdal Dinç Prof., Nazangül Ünal, Zehra Ceren Ertekin
Journal of Food and Drug Analysis
Three-way analysis-based pH-UV-Vis spectroscopy was proposed for quantifying allura red in an energy drink product without the need for chromatographic analysis, and determining the colorant’s pKa without using any titration technique. In this study, UV-Vis spectroscopic data matrices were obtained from absorbance measurements at five different pH levels from pH 8 to pH 12 and arranged as a three-way array (wavelength x sample x pH). In the three-way analysis procedure, parallel factor analysis (PARAFAC) was implemented to decompose the three-way array into a set of trilinear components. Each set of three components relates to spectral, pH and relative concentration profiles …
The Effect Of Whey Protein Supplementation At Breakfast On Tryptophan Levels, Food Intake, And Mood In Postmenopausal Women In A 16-Week Randomized Controlled Trial, Danielle L. Lamont, Jamie I. Baum
The Effect Of Whey Protein Supplementation At Breakfast On Tryptophan Levels, Food Intake, And Mood In Postmenopausal Women In A 16-Week Randomized Controlled Trial, Danielle L. Lamont, Jamie I. Baum
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Whey protein isolate supplementation has been recognized as having potential for regulating appetite, thereby potentially improving mood and food intake. The objectives of this project were to 1) analyze the effects of high-quality whey protein intake on overall diet and 2) identify and examine a correlation between tryptophan levels and mood regulation. This research was conducted using a randomized experimental design. A total of 13 postmenopausal women (12+ months after last reported menstrual cycle) were recruited and allocated to one of two dietary intervention (DI) groups: 1) control (maintain current lifestyle; CON; n = 6), and 2) whey protein isolate …
