Ultrasound-assisted extraction (USAE) is an interesting process to obtain high valuable compounds and could contribute to the increase in the value of some food by-products when used as sources of natural compounds.

Hydro-ethanolic solvent ratio, amplitude, and temperature were the independent factors while % extraction yield, total phenolic content (TPC), total flavonoid content (TFC . Ultrasonic Assisted Extraction (Probe-type) Ultrasonic processor Q700 (700 watts, 20kHz) from QSonica, Newtown, U.S.A with a replaceable flat tip ultrasonic probe (sonotrode) was used to conduct an extraction process of gallic acid and tannic acid from Quercus Infectoria galls. The liquid-to-solid . . Watermelon seed protein was extracted under various operating parameters, and the . Separately, solid-liquid extraction was carried in an orbital shaker using 0.1 M hydrochloric acid at . 'Ultrasound', the term used to describe The freshly prepared methanol extracts of the plants were qualitatively tested for the sounds ranging from 20 kHz to 1 GHz, is usually generated by a transducer which presence of secondary metabolites using standard procedures. Compared to other advanced extraction techniques, UAE is more economic, eco-friendly, and convenient (Teng et al., 2016). The parameters were total extraction total yield, residual solvent content, specific gravity, colour, A major advantage of ultrasound assisted extraction technique is that it does not generate heat. Hielscher's ultrasonic devices generate high intense ultrasound that can be exactely controlled to your process requirements. On the basis of the developed . The extracts of the twice-extraction were mixed. The objective of this study was to demonstrate the potential of US treatment on PAs extracted from kiwifruit (Actinidia chinensis) leaves, and to provide a .

The results obtained indicate that ultrasonic-assisted extraction is an effective method for extracting natural compounds from Zea mays, thus allowing the full use of this abundant and inexpensive industrial waste. Application to the extraction of total fat from oleaginous seeds." by J. LuqueGarcia et al. Enzyme-assisted extraction is a mild, efficient and environmental friendly extraction method and it has been adopted for extracting various kinds of . The impacts of ethanol concentration, extraction time, and . The responses evaluated were-total phenols, flavonoids, ferric reducing assay and yield. Krast, commonly known as "Lingzhi" in Chinese, is a medicinal mushroom that is rich in biologically active substances. peer-to-peer learning project m2rbiotech2020/2021 ul-pharmacy influencing parameters of ultrasound extraction physical parameters: power and frequency high ultrasonic power causes major alterations in materials by inducing greater shear forces most commonly used frequencies are comprised between 20 khz and 100 khz intensity the energy
Ultrasound-assisted extraction (USAE) is an interesting process to obtain high valuable compounds and could contribute to the increase in the value of some food by-products when used as sources of natural compounds. This Paper. Besides classical extraction techniques, it also provides an overview of ultrasound applications and devotes two chapters to proteomics and polymer technology. 2. In order to obtain the maximum yield of TPC and chlorogenic acid from the root of I. helenium, ultrasound-assisted extractions were performed at five extraction time (20, 30, 40, 50 and 60 min).The effect of different extraction time on yield of TPC and chlorogenic acid is shown in Figure 3.
