“…Besides heating, the use of ultrasound-assisted extraction was essential to ensure antioxidant recovery, being a strategy considered efficient in the extraction of antioxidant compounds from leaves and buds of plants, such as Acacia confusa [26]. The results obtained in our study were also in agreement with Boudries et al [27], who claimed to have obtained extracts from Capparis spinosa's buds rich in antioxidant compounds, mainly due to the efficiency of the ultrasound technique. The authors pointed out that this system allows high extraction yields in less processing time, being an ecological and "green" technique.…”

Baccharis dracunculifolia or rosemary-of-field is the principal botanical source used by Africanized bees Apis mellifera L. to produce green propolis in Southeastern Brazil. The phenolic compounds present in the plant and green propolis have been reported to be responsible for biological activities such as antioxidant capacity. This study aimed to optimize the ultrasound-assisted extraction of antioxidants compounds from rosemary-of-field using a central composite rotatable design (CCRD), and compare results to green propolis extract. An experimental design was performed to obtain responses of total phenolic content and antioxidant capacity. The results allowed observing that the optimum condition for both Baccharis dracunculifolia floral bud and raw green propolis antioxidant extraction was obtained with 99% ethanol solution. In this condition, Total Phenolic Content (TPC), Ferric Reducing Antioxidant Power (FRAP), and 2,2-diphenyl-1-picryl-hydrazyl (DPPH) values were 612.14 mg GAE. g−1 sample, 534.39 µM ferrous sulfate g−1 sample, and 72.37 µmol TEAC. g−1 sample, respectively, for floral buds. These results have confirmed that optimization is a key step for effective and sustainable extraction processes to be feasible on an industrial scale. The proposed process can be easily adopted on a larger scale, as it uses very few inputs and presents straightforward steps, with the advantage of high efficiency in the extraction of phenolic compounds from the studied matrices compared to the results from the literature. The high concentration of antioxidants indicates that the products obtained can be considered as a sustainable bioactive source for food and cosmetic purposes.

“…Ultrasonic-assisted ionic liquid extraction (UAILE), a new green extraction approach, can more effectively extract target components from natural products, which can establish a method that has many advantages such as time-saving, simple operation, safety, and high extraction efficiency, and is suitable for the extraction of biflavonoids. − Kou and colleagues used IL-ultrasonic-assisted extraction (UAILE) to extract turmeric polysaccharides from ginger, with a yield of 92.82%. Compared with traditional methods, UAILE not only significantly increased the yield of turmeric polysaccharides but also shortened the extraction time.…”

Selaginella tamariscina, a traditional Chinese medicine, contains a variety of bioactive components, among which biflavonoids are the main active ingredients and have antioxidant, antitumor, and anti-inflammatory properties. In this study, ultrasonic-assisted ionic liquid extraction (UAILE) is used for the first time to extract two main biflavonoids (amentoflavone (AME) and hinokiflavone (HIN)) from S. tamariscina. A high-performance liquid chromatography method is used for the simultaneous determination of AME and HIN in S. tamariscina. Then, three novel ILs are synthesized for the first time by a one-step method using benzoxazole and three acids or acid salts as raw materials, and the structures of the synthesized ILs are characterized by elemental analysis, infrared spectroscopy, and NMR spectroscopy, as well as the thermal stability of the ILs is evaluated by thermogravimetric analysis. After screening the extraction effects of three benzoxazole ILs, three pyridine ILs, and three imidazole ILs, it is found that [Bpy]BF 4 is the best and therefore selected as the extractant. The optimal extraction process is explored in terms of the yields of AME and HIN from S. tamariscina by a single-factor experiments and response surface analysis. Under the optimal level of each influencing factor (IL concentration of 0.15 mol/L, solid−liquid ratio of 1:12 g/mL, ultrasonic power of 280 W, ultrasonic time of 30 min, and three extraction cycles), the extraction rates of AME and HIN from S. tamariscina are 13.51 and 6.74 mg/g, respectively. Moreover, the recovery experiment of [Bpy]BF 4 on the extraction of biflavonoids shows that the recovered IL can repeatedly extract targets six times and the extraction rate is about 90%, which indicates that the IL can be effectively reused. UAILE can effectively and selectively extract AME and HIN, laying the foundation for the application of S. tamariscina.

“…At X 1 = 1:13, X 2 = 82%, X 3 = 45°C and X 4 = 9 min, the experimental value achieved for DPPH activity was 72.04 ± 0.09% which successfully tallied with the predicted result. Boudries et al (2019) optimized extraction from Capparis spinosa flower buds. The predicted optimized values for total phenolics were 36.96 mg GAE/g dm at temperature 60°C, 50% ethanol, US treatment at 100 watts for 240 min.…”

Post COVID-19 pandemic realization and expanding consumer demand for functional nutrition have compelled the food industry to focus on one, clean-label technologies to improve energy expenditure, microbial inactivation, shelf stability, and retention of functional nutrients, and second on the systematic evaluation of food matrices for bioactive potential (functionality) and designing novel food matrices and products healthier than the existing formats. The food industry is rapidly heading toward a "technological convergence" with the goal of establishing highly efficient processing technologies for safe, shelf-stable functional products. Novelty impact statement:In this review, we evaluated the utility and efficiency of various non-thermal processing technologies (cold plasma, ultra-sonication, high pressure, pulsed electric field, pulsed light processing) with respect to their capabilities to retain phytonutrient functionality and antioxidant potential in processed foods. The review also discusses existing gaps in current non thermal processing techniques and explores potential improvements necessary to foster reliable next-generation processing technologies.
