“…As the amplitude increases, the number of compression and expansion cycles of the ultrasonic wave increases and, as a consequence of this, the ultrasonic wave is more effectively administered. Thus, a greater amplitude induces a more intense cavitation effect and improves the extraction process [37]. However, higher values over 70% are not recommended, since it can produce splashes and part of the extract may get wasted.…”

Ultrasound-Assisted Extraction of Two Types of Antioxidant Compounds (TPC and TA) from Black Chokeberry (Aronia melanocarpa L.): Optimization of the Individual and Simultaneous Extraction Methods

Chokeberry (Aronia melanocarpa L.) contains a large number of bioactive compounds, which make of it a highly nutritional and antioxidant food with anti-cancer and anti-inflammatory properties. It has been recently seen its consumption increased because of its interesting composition and properties as a functional food. The ultrasound-assisted extraction method has been optimized, since it is a simple and fast technique to extract phenolic compounds, as well as anthocyanins, not only separately but also simultaneously. Multiple response has been optimized and demonstrated an effectiveness level similar to the individual ones. This represents a considerable reduction in costs, time and work. The optimal conditions for simultaneous extractions were: 54% methanol as extraction solvent at pH 2.72 and 69.4 °C temperature, 70% amplitude, 0.7 s cycle, and 0.5:18.2 g:mL sample mass/solvent volume ratio. The developed methods showed a high precision level with coefficients of variation lower than 5%. The methods were successfully applied to commercial samples. Additionally, the extraction of other compounds of biological interest, such as organic acids and sugars, was also studied.

“…The efficiency of ultrasound‐assisted extraction (UAE) to the removal of phenolic compounds from food materials was reported in various works, such as: mandarin peel (Nipornram, Tochampa, Rattanatraiwong, & Singanusong, 2018), black and purple rice bran (Das, Goud, & Das, 2017), pomegranate peel (Machado et al., 2019; Sharayei, Azarpazhooh, Zomorodi, & Ramaswamy, 2019), teff grains (Viell et al., 2020), and Brazilian hop (Almeida et al, 2019). At same time, UAE efficacy in the extraction of soluble sugars was observed for defatted soybean flakes (Karki et al, 2010), banana (Rayo‐Mendez, Gómez, & Tadini, 2019), and artichoke biomass (Polachini, Mulet, Telis‐Romero, & Cárcel, 2019).…”

The aim of this work was to investigate the ultrasound‐assisted extraction (UAE) of total phenolic compounds (TPC) and soluble sugars (SS) from the by‐product of peach palm (stem portion). The effect of the processing variables temperature (30–60°C), time (15–45 min), and power density (8.47–25.42 mW cm−3) were evaluated. The maximum contents (dry basis) of TPC (345.81 ± 2.82 mg gallic acid equivalent 100 g−1) and SS (16.68 ± 0.24 g 100 g−1) were obtained, respectively, at 60°C, 30 min and 8.47 mW cm−3 (condition 1) and 60°C, 45 min and 25.42 mW cm−3; in these conditions, the extracts had higher sucrose content than glucose and fructose. The highest content of phenolic acids (gallic, coumaric, vanillic, ferulic, trans‐cinnamic) and highest antioxidant activity were obtained in the condition 1. UAE can be considered an effective method for the extraction of TPC and SS from peach palm stem. Practical applications The ultrasound‐assisted extraction (UAE) was applied in the by‐product of heart‐of‐palm (stem portion) to the removal of phenolic compounds and soluble sugars. To realize this process with time and energy economy, the maximized condition of extraction observed at 60°C, 30 min, and 8.47 mW cm−3 was the most interesting. This extract showed the highest content of phenolic compounds and highest antioxidant potential, which can allow its application to preserve the shelf life of food products or to produce food supplements. The soluble sugars extracted can also be used, as example, in fermentative process. Therefore, the results indicate the viability of UAE to offer alternatives to utilization of stem portion of peach palm.

“…This technology was widely used for a great diversity of compounds [3,15,16], but not for the extraction of acetogenins. In a single study reported by Leon-Fernandez et al [17], they found that the use of ultrasonic bath at 42 kHz for 3 h increased the qualitative extraction of acetogenins from soursop pulp compared to extraction by maceration, soxhlet method, and microwaves; however, further trials are required using an ultrasonic equipment with direct application, evaluating factors of amplitude, extraction time, temperature, and ultrasonic cycles (pulse-cycles), to optimize the extraction in different raw materials and different bioactive compounds [18].…”

Ultrasound-Assisted Extraction of Total Acetogenins from the Soursop Fruit by Response Surface Methodology

et al. 2020

The soursop fruit or Annona muricata (A. muricata) fruit is recognized by its bioactive compounds and acetogenins (ACG) are among the most important. The effect of ACGs, with greater importance in health, is that they present anti-tumor activity; however, the methods of extraction of ACGs are very slow and with a high expenditure of solvents. To our knowledge, there is no report of an optimal method for the extraction of acetogenins from the Annonaceae family by ultrasound-assisted extraction (UAE); therefore, the aim was to find the best UEA conditions of acetogenins from A. muricata fruit (peel, pulp, seed, and columella) by using response surface methodology. The effect of amplitude (40%, 70%, and 100%), time (5, 10, and 15 min), and pulse-cycle (0.4, 0.7, and 1 s) of ultrasound at 24 kHz was evaluated on the total acetogenin content (TAC). Optimal extraction conditions of acetogenins (ACGs) with UEA were compared with the extraction of ACGs by maceration. The optimal UEA conditions in the A. muricata pulp and by-products were dependent on each raw material. The highest TAC was found in the seed (13.01 mg/g dry weight (DW)), followed by the peel (1.69 mg/g DW), the pulp (1.67 mg/g DW), and columella (1.52 mg/g DW). The experimental TAC correlated well with the model (Adjusted R2 with values between 0.88 and 0.97). The highest effectiveness in ACG extraction was obtained in seeds and peels using UEA compared to extraction by maceration (993% and 650%, respectively). The results showed that A. muricata by-products are an important source of ACGs and that UAE could be a viable alternative, with high potential for large-scale extraction.
