Kinetics of ultrasound assisted extraction of anthocyanins from Aronia melanocarpa (black chokeberry) wastes

Red Fruits: Extraction of Antioxidants, Phenolic Content, and Radical Scavenging Determination: A Review

“…The observed positive effect of temperature could be explained by the higher solubility of polyphenols in the solvent, the higher diffusivities of the extracted molecules, and the improved mass transfer at higher temperatures. However, a more recent study by the same author proved that at high temperatures (70 °C), a decrease of anthocyanins yield with time was observed, suggesting their thermal degradation at such conditions [10]. This idea is supported by another study [16] which claims that high temperatures coupled with exposure to molecular oxygen may degrade certain groups of bioactive compounds including anthocyanins, which are important antioxidants in red fruits.…”

“…Some authors [10] proved that ultrasound assistance improves considerably both yields of extraction of phenolics. They found out low frequencies (20 kHz) were enough to extract efficiently anthocyanins from Aronia melanocarpa and higher frequencies could cause degradation of these compounds.…”

“…Anthocyanins are water-soluble plant pigments responsible for the blue, purple, and red color of many plant tissues [10]. Anthocyanidins are based on the flavylium ion, or 2-phenylchromenylium.…”

Quality Characteristics and Antioxidant Activity of Sulgidduk Prepared by Addition of Aronia Powder (Aronia melanocarpa)

“…아로니아는 항산화 작용을 비롯하여 심혈관계 및 소화기 계 질환에 대해 높은 예방 및 치료 효과를 나타내는 것으로 알 려져 있으며, 암 예방, 항균 활성, 면역 증강, DNA 손상 억제 등 에 대한 연구가 활발하게 이루어지고 있다 (7,10,11). 국내에는 아 로니아 재배가 활성화되지 않아 아직까지 지속적으로 생산되는 아로니아를 활용한 가공식품은 많지 없으나 해외에서는 아로니 아를 활용한 음료, 건조분말, 화장품 등이 출시되고 있으며 이들 제품의 기능성에 관련된 다수의 논문들이 보고되고 있다 (12)(13)(14)(15). 폴린-시모칼토페놀시약(Folin-Ciocalteu's phenol reagent), 1,1-다 이페닐-2-피크릴하이드라질(1,1-diphenyl-2-picrylhydrazyl, DPPH), 갈산(gallic acid), 카테킨(catechin), 나이트로 블루 염화테트라졸륨 (nitro blue tetrazolium chloride, NBT), 니코틴 아마이드 아데닌 다이뉴클레오타이드(nicotinamide adenine dinucleotide, NADH), 트 리스 염산(Tris-HCl), 파라메틸스타이렌(para-methyl styrene, PMS), 인산이수소소듐(sodium phosphate monobasic), 그리고 데오시-디- Aronia powder (1, 3 and 5%) was added based on the total weight of rice powder.…”

Optimization of polyphenols extraction from dried chokeberry using maceration as traditional technique

“…Only optimization of ultrasound-assisted extraction of polyphenols from chokeberry and chokeberry by-products has been studied previously (Galvan D'Alessandro, Dimitrov, Vauchel, & Nikov, 2014;Galvan D'Alessandro, Kriaa, Nikov, & Dimitrov, 2012;Ramić et al, 2015). Considering that phenolic molecules possesses beneficial effects on human health, and the industry set up demands for reduction of production costs, it is worthwhile to investigate the optimal conditions for the efficient extraction of chokeberry polyphenols.…”
