“…This IDF is conventionally extracted through the use of detrimental chemicals NaOH or H 2 SO 4 , which is still popular in the food processing industry because it yields more quantity (Ma & Mu, 2016; Maphosa & Jideani, 2016; Yang et al, 2017). Alkaline and acidic extraction methods, however, adversely affect different functional properties, especially water retention capacity, foaming capacity and viscosity, glucose adsorption capacity, and the inhibition ability toward the α‐amylase (Ahmad et al, 2009; Poyraz et al, 2021). Though many more practical sources have been identified for extraction of dietary fibers, resulting in change of their chemistry later on but almost all forms act as potential runners for industrial and nutraceutical industry.…”

Ultrasonic‐assisted extraction technique by means of response surface methodology was used to study optimized conditions for extraction of insoluble dietary fiber (IDF) from wheat bran varieties, namely Zincol‐2016 (ZL), Borlaug‐2016 (BG), NARC (NC), and Pakistan‐2013 (PN). Optimized parameters for time, temperature, and amplitude ranged from 10 to 11 min for 30–40°C, and 64%–65% for all varieties with extracted IDF (39%–41%). FTIR spectra confirmed the presence of IDF in extracted material. DSC showed endothermic behavior near 100°C during the melting process. TGA showed stability at 99°C and complete degradation at 372°C. Chemical characterization of IDF extract showed a reduction in protein and fat, thus improving purity and IDF content. Tested technique also improved functional properties like cation exchange capacity (meq/kg) 16.30–17.66, emulsifying capacity (%) 32.1–32.98, and swelling capacity (ml/g) 4.43–5.98 to a high level. Briefly, under‐tested extraction parameters, the IDF has improved chemical and functional characteristics. Practical applications The study concludes that ultrasonic extraction, under‐explored moderate, and optimized conditions will prove an efficient extraction technique yielding considerable quantity and quality of IDF from wheat bran. The above results show the possibility for the application of all tested samples of IDFs in the food industry, especially to expand the thermal stability of food for various purposes. The ultrasonically extracted IDFs have better structural integrity and functional characteristics which play an important part in preparation and quality maintenance of food products, especially cereal food products.

“…Most studies on the valorization of citrus peels are focused on the extraction of phenolic compounds [34]. Poyraz et al [3], in their work on the use of Satsuma mandarin (Citrus unshiu) peel to obtain high value-added bioactive ingredients, optimized the UAE of total phenolics and flavonoids from fresh peel and concluded that the application of 90 min processing at 50 • C, with 56% ultrasound amplitude, leads to the recovery of 8.95 mg gallic acid equivalents/g peel and 5.25 mg catechin equivalents/g peel, respectively. Inoue et al [35] also optimized the microwave-assisted extraction (MAE) of hesperidin, an active flavanone glycoside, from Citrus unshiu peel, applying an RSM-coupled central composite design of 13 experimental points.…”

“…A considerable part of these by-products comes from food manufacturing and is usually deposited in open-air landfills, interfering with the balance of the ecosystem, which has led both the industry and academia to work on a sustainable solution to reduce the disposal of biowaste [2,3]. One of the purposed solutions involves the combination of the upcycling of biowaste and by-products into high added-value products with the subsequent use of waste in industries, such as bioenergetics [4,5].…”

The production of citrus juice generates a large quantity of by-products, which are often discarded or used for animal feed. However, several studies have shown its richness in valuable compounds, namely organic acids. Thus, this work intended to valorize orange and lime peels as renewable sources of citric acid. An experimental design combining five levels of the independent variables time (2–45 min), ultrasonic power (50–500 W), and ethanol proportion (0–100%) was implemented and response surface methodology (RSM) was applied to optimize the extraction process. The UPLC-PDA analysis showed that orange peel presented a higher citric acid content than lime. For lime and orange peels, the extraction yield was maximized by sonicating at low power for 5.8 or 35.5 min, using a low ethanol proportion or only water as a solvent, respectively. Overall, optimal UAE conditions were defined for the sustainable extraction of citric acid from citrus by-products, thus contributing to its valorization and upcycling into natural food ingredients.

“…Nowadays, the response surface methodology (RSM) technique has been widely used as a powerful tool to determine the optimum condition of variables in several engineering fields (Barzegar et al, 2019;Şahin et al, 2020;Vebber et al, 2019). The works on the optimization of ultrasonic-assisted extraction using RSM have been widely investigated (Poyraz et al, 2021;Şahin et al, 2020).…”

The main purpose of the present study is to predict the optimal values of the ultrasound-extraction conditions by employing the response surface method based on Box-Behnken design from Moringa oleifera leaves. The impact of three independent variables, namely the extraction time (5,15, and 25 min), solid to the solvent ratio (60%, 70%, and 80%), and ultrasonic amplitude (20%, 60%, and 100%) on the extraction yield and total phenolic/flavonoid content were studied. Analysis of variance (ANOVA) was employed to estimate the significance of the independent parameters and the model. An extraction time of 15 min, an ultrasonic amplitude of 100%, and a solid to solvent ratio of 80% were found to be optimal values. The findings of this investigation revealed that at optimal independent factors, the values of the extraction yield, total flavonoids, and phenolics content were found to be 83.75 mgL −1 ,50 mgL −1 , and 0.974 g, respectively. The obtained results indicated that BBD-RSM design could effectively be used in the optimization of the ultrasonic-assisted extraction process. To the best of our knowledge, this is the first study assessing the effect of US power, time of extraction, and solid to the solvent ratio on the extraction yield and phenolics content/flavonoids content of Moringa oleifera leaves cultivated in Iran.
