Highly-Efficient Release of Ferulic Acid from Agro-Industrial By-Products via Enzymatic Hydrolysis with Cellulose-Degrading Enzymes: Part I–The Superiority of Hydrolytic Enzymes Versus Conventional Hydrolysis
Historically Triticum aestívum L. and Secale cereále L. are widely used in the production of bakery products. From the total volume of grain cultivated, roughly 85% is used for the manufacturing of flour, while the remaining part is discarded or utilized rather inefficiently. The limited value attached to bran is associated with their structural complexity, i.e., the presence of cellulose, hemicellulose, and lignin, which makes this material suitable mostly as a feed supplement, while in food production its use presents a challenge. To valorize these materials to food and pharmaceutical applications, additional pre-treatment is required. In the present study, an effective, sustainable, and …
Valorization of Wild Apple (Malus spp.) By-Products as a Source of Essential Fatty Acids, Tocopherols and Phytosterols with Antimicrobial Activity
The amplified production of fruit as well as burgeoning demand for plant-made food products have resulted in a sharp increase of waste. Currently, millions of tons of by-products are either being discarded or utilized rather ineffectively. However, these by-products may be processed and further incorporated as functional ingredients in making high-value food products with many physiological and biochemical effects. The chemical analysis of pomace oils using gas chromatography-mass spectrometry (GC/MS) and reversed-phase-liquid chromatography coupled with fluorescence detector (RP-HPLC/FLD) systems led to the identification and quantification of 56 individual lipophilic compounds including u…
Wild apple (Malus spp.) by-products as a source of phenolic compounds and vitamin C for food applications
Abstract The phytochemical profile and positive health effects of the fruits and by-products of domesticated Malus domestica Borkh. apple cultivars have been extensively investigated. The present study was designed to evaluate the hydrophilic composition and antioxidant activity of the compounds recovered from wild apple Malus spp. by-products. The phytochemical analysis of the 30 and 96% ethanolic extracts using LC-DAD-ESI-MS/MS has led to the detection and isolation of 25 hydrophilic compounds. Amongst the polyphenols, chlorogenic acid, B-type procyanidins, and phloretin-2-glucoside dominated. The results of HPLC-DPPH• radical scavenging showed that the major contributors to the antioxida…
