Dietary fiber is one of value added products from cassava pulp, byproduct of cassava starch industry. It could be produced by enzymatic digestion in which the optimal condition was studied. The three independent variables are heating temperature (°C) after adding α-amylase concentration (%v/v) and amyloglucosidase concentration (%v/v) regarding of two responses solid percentage yield and neutral detergent fiber (NDF) in the digested sample. The experimental design was based on central composite design. The highest solid percentage yield and NDF of cassava byproduct could get from enzymatic digestion condition at heating temperature at 90 °C, α-amylase concentration of 0.3 % (v/v), and amyloglucosidase concentration of 0.5 % (v/v). For ultrasound-assisted preparation was investigated at the optimum condition of enzymatic digestion. Ultrasound condition was control power of 140% and a frequency of 40 kHz for 15 min. The ultrasound was applied at pre-treatment condition (before adding α-amylase, PU) collocated with intermediate condition (before adding amyloglucosidase, IU) higher NDF yield than optimal condition at 18.78%. In addition, this ultrasound assisted technique give the highest solid percentage.

Abstract Background: Derris reticulata or Oi Sam Saun is a highly sweet Thai plant, rich in bioactive compounds, and widely used for its medicinal properties. In this study, sweet aqueous extracts from the stems of Oi Sam Saun were extracted using ultrasound-assisted extraction (UAE). Phenolic, flavonoid, and sugar compound extraction was optimized using the Box-Behnken design (BBD) and response surface methodology (RSM). Methods: Three independent variables—extraction temperature (40–80°C), sonication time (20–60 min), and extraction ratio (1:10–1:30 g/mL)—were investigated, and the optimal condition was used to determined phenolics, flavonoid and 18β-glycyrrhetinic acid by High performance liquid chromatography-diode array detector (HPLC-DAD). Sensory evaluation was also performed.Results: The values of 84°C, 64 min, and ratio 1:8 g/mL were found to be optimal. Under these conditions, experimental values were well correlated with predicted values, and phenolic, flavonoid, and sugar contents were determined as 0.4725 mgGAE/gDW, 0.1489 ± 0.033 mgCE/gDW, and 4.802 ± 0.651 mg/gDW, respectively. Gallic acid, p-coumaric acid, quercetin, and kaempferol was also found in optimal condition. Moreover, the extract contained 18β-glycyrrhetinic acid (0.529 ± 0.002 mg/100 mg) and was 166 times sweeter than sucrose.Conclusion: High level of phenolics, flavonoids and sugars was detected in optimal condition of the extract. Therefore, this Thai medicinal plant, which has several pharmacological benefits, is newly potentially and applicable as a sweetening agent or sugar substitute in foods.

The ‘Bravo de Esmolfe’ apple (BE) is rich in antioxidants and represents one of the most important traditional cultivars in Portugal. A large amount of non-compliant BE, with no market value, it is generated every year. Thus, an effort to find value-added solutions is of utmost importance. For the first time, green extraction (microwave-assisted-extraction (MAE) and ultrasound-assisted-extraction (UAE)) were compared against conventional extraction (with (CET) and without temperature (CE)) to select the most efficient process to produce a natural antioxidant extract from non-compliant BE. The results showed that MAE and CET are good methodologies for developing a BE antioxidant extract. However, MAE is more sustainable than CET, requiring less time to reach high temperatures. The MAE-extract showed great antioxidant activity (14.80 ± 0.70 mg TE/g DE by ORAC, 3.92 ± 0.25 mg AAE/g DE by ABTS, and 5.11 ± 0.13 mg TE/g DE by DPPH). This extract revealed high amount of chlorogenic acid (0.48 ± 0.07 mg/g DE), (-)-epicatechin (0.30 ± 0.02 mg/g DE) and phloridzin (0.13 ± 0.01 mg/g DE). This study shows that non-compliant BE is a useful source of antioxidants, being a sustainable way for the recovery of value-added compounds from the rejected fruit in line with sustainable and circular bioeconomy principles.

Hasil ini juga menunjukkan bahwa ekstrak etanol memiliki aktivitas antioksidan yang lebih kuat dalam aktivitas pemulungan radikal dan mengurangi daya antioksidan. Studi ini menyimpulkan bahwa waktu ekstraksi dan jenis pelarut mempengaruhi total kandungan fenolik dan aktivitas antioksidan. Kata kunci:  ABSTRACT The objective of this study was to determine solvents effect and extraction time of ultrasound-assisted extraction of corncob insoluble dietary fiber (IDF) powder and their antioxidant activities. Ethanol and acetone were used to extract phenolic components from corncob IDF powder with extraction time (30, 60, 90, 120, 150 and 180 min) in an ultrasonic bath (Krisbow 42 kHz, 50 watt). The both extracts were evaluated on the phenolic content and antioxidant activity with spectrophotometry method. The results of the phenolics content expressed in μg/mL of gallic acid equivalent showed that ethanol extract has highest phenolic content compared with acetone extract of all the extraction time. The radical scavenging activity of extract ethanol exhibited strong than acetone extract of all extraction time tested. The result also showed that the ethanol extract has highest the total antioxidant capacity compared with acetone extract at all extraction time. This result suggest that corncob IDF powder especially the ethanol extract are very rich in phenolic component which is potential as antioxidant dietary fiber.Keyword: corncob, dietary fiber, ultrasonic, extraction time, phenolic, antioxidant

Bioactive Phenols-loaded chitosan nanoparticles (PL-CNps) were developed by ionic gelation from Persian lemon (Citrus latifolia) waste (PLW) and chitosan nanoparticles. Response Surface Methodology (RSM) was used to determine the optimal Ultrasound-Assisted Extraction (UAE) conditions for the total phenolic compounds (TPC) recovery from PLW (58.13 mg GAE/g dw), evaluating the ethanol concentration, extraction time, amplitude, and solid/liquid ratio. Eight compounds expressed as mg/g dry weight (dw) were identified by ultra-performance liquid chromatography coupled photo diode array (UPLC-PDA) analysis: eriocitrin (20.71 ± 0.09), diosmin (18.59 ± 0.13), hesperidin (7.30 ± 0.04), sinapic acid (3.67 ± 0.04), catechin (2.92 ± 0.05), coumaric acid (2.86 ± 0.01), neohesperidin (1.63 ± 0.00), and naringenin (0.44 ± 0.00). The PL-CNps presented size of 232.7 nm, polydispersity index of 0.182, Z potential of −3.8 mV, and encapsulation efficiency of 81.16%. The results indicated that a synergic effect between phenolic compounds from PLW and chitosan nanoparticles was observed in antioxidant and antibacterial activity, according to Limpel’s equation. Such results indicate that PLW in such bioprocesses shows excellent potential as substrates for the production of value-added compounds with a special application for the food industry.

Pomelo (Citrus maxima (Burm.) Merrill) peel, which has been considered as a byproduct, is a potential source of flavonoids. In this study, the extraction conditions of total flavonoids from peels of Da Xanh pomelo were optimized using the response surface methodology with the Box–Behnken design. The combination of two novel extraction methods, including enzyme-assisted and ultrasound-assisted extractions, was used for the optimization. The results indicated that the optimal extraction condition was a liquid-to-solid ratio of 142.99 mL/g, enzyme concentration of 3.45%, and the time of 65.23 min for incubation and of 69.26 min for sonication treatment. Total phenolic and total flavonoid contents of the pomelo peel extracts, under optimal condition of the combined method (16.79 mg GAE/g and 10.69 mg RE/g, respectively), were significantly higher than those of the conventional method (6.58 mg GAE/g and 2.42 mg RE/g, respectively). The naringin and hesperidin contents of extracts under optimal condition increased by 5.70% and 1.20%, respectively, compared to the extracts under the conventional method.
