“…Berry press residues, obtained after juice extraction, are excellent source of phenolic compounds. Klavins et al [41] reported that berries press residues from Vaccinum L. genus berries (bilberries, blueberries, lingonberries, cranberries) to be an excellent source of anthocyanins which are helpful for the prevention of various chronic diseases such as artherosclerosis, cancer and cardiovascular disease. Kitrytė et al [89] via use of enzyme-assisted extraction recovered phenolic compounds from chokeberry press residues.…”

Sustainable utilization of agri-food wastes and by-products for producing value-added products (for cosmetic, pharmaceutical or food industrial applications) provides an opportunity for earning additional income for the dependent industrial sector. Besides, effective valorisation of wastes/by-products can efficiently help in reducing environmental stress by decreasing unwarranted pollution. The major focus of this review is to provide comprehensive information on valorisation of agri-food wastes and by-products with focus laid on bioactive compounds and bioactivity. The review covers the bioactives identified from wastes and by-products of plants (fruits, exotic fruits, vegetables and seeds), animals (dairy and meat) and marine (fish, shellfish seaweeds) resources. Further, insights on the present status and future challenges of sustainably utilizing agri-food wastes/by-products for value addition will be highlighted.

“…On the other hand, in order to maximize the recovery of bioactive compounds such as polyphenols and anthocyanins, optimization of the extraction conditions is needed. UAE has been successfully used to extract the anthocyanins from different food sources, such as black chokeberries (Galván D'Alessandro, Dimitrov, Vauchel, & Nikov, 2014), cranberries (Klavins, Kviesis, Nakurte, & Klavins, 2018), haskap berries (Celli et al, 2015), blueberries, cherries, and red pear peels (Wang, Jung, Tomasino, & Zhao, 2016). However, to the best of our knowledge, there are no reports on the optimization of the extraction conditions of anthocyanins and total phenolic compounds from cornelian cherry.…”

Cornelian cherry fruits are rich in health-related compounds. In the present study, the ultrasoundassisted extraction was used to maximize the recovery of anthocyanins and phenolic compounds from cornelian cherry. The optimal extraction conditions were determined and the influence of independent variables was checked through response surface methodology. The maximum recovery of anthocyanin and total phenolic compounds was obtained after 40 min at 30°C, when performing the extraction with aqueous ethanol of 80% and 60%, respectively. The major anthocyanins identified through HPLC were cyanidin-3-rutinoside and cyanidin-3-glucoside. The thermal degradation kinetic study revealed that up to 120°C, the anthocyanins from cornelian cherry were thermo-resistant, whereas at more severe temperatures were easily degraded. The kinetics of the heat-induced changes in total monomeric anthocyanins followed a first-order kinetic model, allowing to predict the thermal degradation parameters.

“…Berry processing generates large quantities of pomace, which consists of skin, seeds and some flesh [ 6 , 7 , 8 ]. Berry flesh contains about 10% of the total polyphenols, while the skin and seeds contain 28–35% and 60–70%, respectively, which makes berry processing by-products an excellent source of polyphenols [ 9 ]. According to Struck et al [ 10 ], processing berries into juice leaves approximately 20–30% of the fruit as pomace.…”

Influence of Extraction Conditions on Ultrasound-Assisted Recovery of Bioactive Phenolics from Blueberry Pomace and Their Antioxidant Activity

et al. 2018

The increase in diet-related chronic diseases has prompted the search for health-promoting compounds and methods to ensure their quality. Blueberry pomace is a rich yet underutilized source of bioactive polyphenols. For these high-value bioactive molecules, ultrasound-assisted extraction (USAE) is an attractive and green alternative to conventional extraction techniques for improving purity and yields. This study aimed to assess the impact of USAE parameters (sonication time, solvent composition, solid/liquid ratio, pH and temperature) on the recovery of phenolic compounds from blueberry pomace and antioxidant activity of the extracts. Total phenolic, flavonoid and anthocyanin contents (TPC, TFC and TAC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity were analysed. USAE in 50% ethanol/water was the most efficient, yielding the highest TPC (22.33 mg/g dry matter (DM)), TFC (19.41 mg/g DM), TAC (31.32 mg/g DM) and DPPH radical scavenging activity (41.79 mg Trolox/g DM). USAE in water showed the lowest values even at low (1/40) solid/liquid ratio (7.85 mg/g DM, 3.49 mg/g DM, and 18.96 mg/g DM for TPC, TFC and TAC, respectively). Decreasing the solid/liquid ratio in water or 50% ethanol significantly increased TPC, TFC, TAC and DPPH radical scavenging. With ethanol, increasing the temperature in the range 20–40 °C decreased TPC but increased TFC and DPPH radical scavenging activity. Anthocyanin profiles of water and ethanolic extracts were qualitatively similar, consisting of malvidin, delphinidin, petunidin and cyanidin. These findings indicate that USAE is a method of choice for extracting high-value bioactive phenolics from blueberry pomace. Selective enrichment of different phenolic fractions is possible under select extraction conditions.
