In recent years, there has been a growing interest in the application of antioxidants food and pharmaceuticals due to their association with beneficial health effects against numerous oxidative-related human diseases. The antioxidant potential can be measured by various assays specific mechanisms action, including hydrogen atom transfer, single electron targeted scavenging activities. Understanding chemistry mechanisms, advantages, limitations methods is critical for proper selection techniques valid assessment activity samples or conditions. There are analytical available determining biological samples, plant extracts. different categorized into three main groups, such as spectrometry, chromatography, electrochemistry techniques. Among these assays, spectrophotometric considered most common technique determination sensitivity, rapidness, low cost, reproducibility. This review covers mechanism actions color changes that occur each method. Furthermore, advantages described discussed this review.

Apples and Apple by-Products: Antioxidant Properties and Food Applications

Antioxidants, Год журнала: 2023, Номер 12(7), С. 1456 - 1456

Опубликована: Июль 19, 2023

In recent years, there has been a growing interest in utilizing natural antioxidants as alternatives to synthetic additives food products. Apples and apple by-products have gained attention potential source of due their rich phenolic content. However, the extraction techniques applied for recovery compounds need be chosen carefully. Studies show that ultrasound-assisted is most promising technique. High yields with antioxidant properties obtained by applying ultrasound on both apples by-products. Promising results also reported green technologies such supercritical fluid extraction, especially when co-solvent used. Once extracted, studies indicate feasibility using these products packaging materials. The present review aims provide comprehensive overview by-products, techniques, applications because or nutritional properties. findings here highlight proper utilization reduce detrimental effect environment positive impact economy.

Reuse of fruits and vegetables biowaste for sustainable development of natural ingredients

Food Bioscience, Год журнала: 2023, Номер 53, С. 102711 - 102711

Опубликована: Май 21, 2023

Considering the annual waste in food sector that occurs throughout value chain, it is important to establish strategic measures reduce, and reintroduce them into industrial sector. Additionally, constant search for development of sustainable strategies promote safe healthy products consumers has gained great prominence. Biowastes from fruits vegetables present their composition an excellent source compounds interest, which can be reused different technological routes, providing added industrial, socioeconomic therapeutic sectors. In particular, phenolic fruit vegetable biowastes, have bioactive preservative characteristics are candidates natural ingredients substitutes synthetic preservatives. As list identified extensive accessible, interest these gaining more prominence, since use origin being delayed by actions harmful health consumer. Phenolic compounds, addition having capacity, such as antioxidant antimicrobial also known anti-inflammatory, anticancer, antidiabetic, antiallergic other biological properties, increases functional nutraceutical preparations. Based on this, this review gathers information impacts exacerbated generation generate environmental, economic social sectors, well lists ways reusing wastes, highlighting compounds.

Spray‐drying microencapsulation of blackcurrant and cocoa polyphenols using underexplored plant‐based protein sources

Journal of Food Science, Год журнала: 2023, Номер 88(6), С. 2665 - 2678

Опубликована: Май 9, 2023

The performance of buckwheat protein (BK) and chia seed (CP) as drying carriers for the microencapsulation polyphenols extracted from blackcurrant pomace cocoa powder was investigated. Four experimental groups were evaluated (BK-BC: extract with protein; CP-BC: chia:pea blend; BK-CC: CP-CC: blend) to determine physicochemical attributes, phytochemical content, antioxidant activity, polyphenol in vitro bioaccessibility. Nonconventional, underexploited sources such chia/pea blend efficiently produced functional microparticles attractive color texture, low hygroscopicity (<20% increase moisture content when exposed 86% relative humidity 1 week), solubility above 50% at pH 7 10, uniform particle size (29 < D4,3 56 µm). Besides this, protein-polyphenol concentrated protected health-relevant content. Anthocyanins detected treatments (around 20 mg cyanidin-3-O-glucoside equivalents/g), while proanthocyanidins (PAC) most prevalent (>100 PAC B2/g). Monomers main class both BK-CC CP-CC treatments. All reduced reactive oxygen species nitric oxide production lipopolysaccharide-activated cells (p 0.05). recovery index high (>70%) oral gastric phases, BK-derived had better bioaccessibility compared BC or CC alone (noncomplexed). This research provided a framework delivery high-value ingredients attend an emerging market centered on protein-rich, clean label plant-based food products. PRACTICAL APPLICATION: Practical Application: complexation is robust method produce phytochemical-rich industry enhanced physicochemical, sensory, performance. In this study, we investigated practical aspects regarding quality particles, spray-drying efficiency, study unveils potential underexplored seeds (alone combined pea protein) encapsulation fruit diversify options available products directed wellness market.
