Influence of Stems Petioles and Leaves on the Phenolic Content of Concord and Aurora Blanc Juice and Wine PAO‐JUI DAVID HUANG Author Huang is with Best Foods Research Engineering Center 1120 Commerce Ave Union NJ 07083 Authors Cash and Santerre are with the Dept of Food Science Human Nutrition Michigan State Univ East Lansing

Sep 01 2020Furthermore the influence of sonication and osmotic dehydration applications on the physico-chemical characteristics of persimmon (moisture content rehydration rate bulk density total phenolic content and color values) was also investigated 2 Materials and methods 2 1 Raw material

Overall sonication had a positive effect on the total flavonoid content in all the juice samples followed by microwave treatment with exceptions in some cases High-performance liquid chromatography study showed the presence of different phenolic acids depending on the sample type

Jun 25 2011Sonication treatments using methanol as an extraction solvent has been reported to enhance the bioactive compounds in plants and their products thus supporting our observations (Wang et al 2008 Paniwnyk et al 2009) Sonication treatment induces microstreaming effect and can enhance the mass transfer produced on the cavitational bubble collapse

Effect of sonication conditions: solvent time and

temperature of sonication and t is the sonication time Samples sonicated under Argon in water were referred to"S-V-Argon-T-t" For all experiments under argon the vermiculite suspensions were deoxygenized with argon bubbling for 12 h prior to sonication and also during the ultrasonic treatment

Contrarily flesh extracted by using CV had higher TFC (510 69 7 54 mg% dry basis compared to UE (245 31 6 04 mg% dry basis) Flavonoid is a subset of phenolic compounds however high flavonoid content does not lead to high total phenolic content in this present study

Jun 25 2011Sonication treatments using methanol as an extraction solvent has been reported to enhance the bioactive compounds in plants and their products thus supporting our observations (Wang et al 2008 Paniwnyk et al 2009) Sonication treatment induces microstreaming effect and can enhance the mass transfer produced on the cavitational bubble collapse

Ultrasound processing can result in cell wall disruption facilitating the release of the cellular content Therefore we hypothesized that sonication of vegetables could be used as a pre-treatment to increase the bioaccessibility of phenolic and antioxidant compounds Overall sonication (40 kHz 250 W 4 C 20 min) did not affect the main physicochemical parameters of tomato lettuce

Total phenolic content The total polyphenol content (TPC) of Doum fruit sample extracts was estimated colorimetrically using Folin–Ciocalteu reagent [8] The appropriately diluted extract (200 L) was mixed with 15 mL distilled water in a 25 mL volumetric flask subsequently 1 25 mL undiluted Folin– Ciocalteu reagent was added

The increase in the content of phenolic compounds during UHP treatment might be due to the secretion of the bound forms of these compounds in juice [4 31] At 25 C vitamin C and polyphenol content hardly changed after ultrasonic treatment as compared to control This indicated sonication only exerted a minor effect on antioxidants

The influence of the degradation of the phenolic compounds on their antioxidant properties was elucidated by a electron spin resonance (ESR) spectrometry study of the reaction samples mixed with the stabilized radical Fremy's salt Bijun Xie Zhida Sun Effect of Thermo-Sonication and Ultra-High Pressure on the Quality and Phenolic

Jun 06 2018The study aimed to determine the influence of different fertilizer treatments on the milling potentials (brown rice milled rice and head rice recovery) and total phenolic content of aromatic rice The two-year field experiment laid out in Split Plot Design with three replications was carried out in irrigated lowland rice soil in San Nicolas Ilocos Norte

Influence of Extraction Conditions on Ultrasound

2 1 Effect of Sonication Time on the Phenolic Contents of Blueberry Pomace Water Extracts The effect of sonication time (from 30 to 90 min) was assessed using water as the extraction solvent with a solid/liquid ratio of 1/20 at 40 C The results are shown in Figure1 Overall the water extracts

In this study the influence of stevia addition and sonication processing parameters on the phenolic content and profile as well as the steviol glycosides of strawberry juice-based samples was investigated For this purpose three matrices—control samples of strawberry juices without green stevia powder (CS) strawberry juices with green stevia powder (JGSP) and sonicated juices with green
