Due to renewed interest in fruit residue application, cashew apple pomace and other fruit pomace are receiving unparallel attention as substitute for food ingredient or food enrichment options. This necessitates this study to investigate drying as vital approach in preserving and conditioning cashew apple pomace. In this study, cashew apple fruits were blended in fruit blender and filtered through 150 microns filter; the filtrate was further tightened in a fabric material and pressed with manual hydraulic press to further express the juice in it. The pomace was stored in a refrigerator at 3 ?C for 18 h to homogenise the moisture. The pomace was divided into nine equal weights, a portion was fed into hot air oven dryer at 60 ?C and constant circulating air velocity of 2.2 m/s, the changes in mass was measured using digital mass balance after every 10 minutes. The procedure was repeated at 70 and 80 ?C and in triplicate; in each case the mass of the samples was measured. It was found that cashew pomace dry under a single falling rate period, effective moisture diffusivity increased with increasing drying temperature and ranges from 9.02015?10-9 to 2.12177?10-8, activation energy was estimated as 41.880 kJ/K, specific drying energy consumption decreased with increasing drying temperature and ranges from 24.1 to 45.3 MJ/kg. Our proposed drying model was found to adequately simulate the drying kinetics of cashew apple pomace.

AbstractApple pomace contains a large amount of useful bioactive compounds that have wide application in the food industry. In this study the effect of drying temperature and pressure (high temperature 80 °C and low temperature 60 °C using a conventional oven and a combination of conventional plus vacuum drying oven) on the antioxidant capacity and phenolic compounds of apple pomace extract was investigated. For a combination of conventional and vacuum drying ovens, samples were first dried by a conventional oven to a moisture content of approximately 10% then vacuum dried to reach a final moisture content of 3–4%. After the drying processes, ethanolic extraction was performed and the amount of total polyphenol and the antioxidant capacity (FRAP) were evaluated to determine a best drying method. The drying curves were also determined. The drying temperature affects the duration of the drying, the rate of water loss, and the remaining amount of antioxidant compounds.

Plodovi grejpfruta značajno se ističu bogatim nutritivnim sastavom, posebice sadržajem vitamina C, polifenolnih spojeva i snažnom antioksidacijskom aktivnosti. Sastav i sadržaj fitokemikalija uvelike ovisi o genetskim svojstvima vrste odnosno sorte. Stoga je i cilj ovog istraživanja bio utvrditi fizikalno-kemijska svojstva, sadržaj bioatkivnih spojeva i antioksidacijski potencijal plodova grejpfruta dviju različitih sorti: 'Marsh Seedless' i 'Natzumikan'. Obje sorte grejpfruta ubrane su u nasadu agruma na području Opuzena. Istraživane sorte ne razlikuju se značajno u sadržaju ukupne suhe tvari (prosječna utvrđena vrijednost 11,55%), topljive suhe tvari (prosječna utvrđena vrijednost 9,89%) kao ni u sadržaju vitamina C (prosječna utvrđena vrijednost 42,92 mg/100 g svježe tvari). No, značajnije razlike utvrđene su u sadržaju polifenolnih spojeva prilikom čega su kod sorte 'Natzumikan' utvrđene čak 66% više vrijednosti ukupnih fenola, 76% više ukupnih flavonoida i 54% više ukupnih neflavonoida u usporedbi sa sortom 'Marsh Seedless'. Također, sorta 'Natzumikan' imala je i značajnije veći antikodiacijski kapacitet (1,68 mmol TE/L). Temeljem svega može se zaključiti kako su plodovi grejpfruta značajan izvor vrijednih fitokemikalija, značajnih za ljudsko zdravlje.

Food Ingredient

The fatty acid (FA), polyphenol content and evaluation of the antioxidant capacity of exhausted Myrtus communis berries (EMB) resulting from the production of myrtle liqueur were assessed. All parts of the exhausted berries exhibited high concentrations of carbohydrates, proteins, lipids and phenolic compounds. The lipid fraction contained a high amount of poly unsaturated fatty acids (PUFA), mainly represented by linoleic acid (>70%). Of the phenolic acids evaluated by liquid chromatography/mass spectrometry, ellagic acid was the most predominant (>50%), followed by gallic and quinic acids. Quercetin and quercetin3-O-rhamnoside were the most abundant flavonoids. The seed extracts showed a higher antioxidant potential than the pericarp extracts; the same trend was observed for total phenolic compounds evaluated by spectrophotometric assay. The overall high content of bioactive compounds and the high antioxidant potential of this byproduct sustain its suitability for a number of industrial applications, such as a food ingredient in novel foods, an additive in cosmetic formulations or a component of animal feed formulations.

Vegetation Water

In the Rural Development Plan (2014–2020), the European Commission encouraged the conversion and supported the maintenance of organic farming. Organic olive oil (bioEVOO) production involves the use of environmentally sustainable fertilizers and the recycling of olive pomace (Pom) and olive vegetation waters (VW) to reduce the environmental impact of these wastes. An ecofriendly way to recycle olive wastes is to reuse them to extract bioactive compounds. In this study, the total phenolic compounds content, their profile and dosage, the antioxidant action in oil, pomace, and vegetation water was evaluated when the Trichoderma harzianum M10 was used as a biostimulant in agriculture. Two spectrophotometric tests (2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic) acid (ABTS)) evaluated the antioxidant potential of samples, a spectrophotometric method estimated total phenolic content, and an Ultra-High-Performance Liquid Chromatography (UHPLC)–Orbitrap method evaluated the phenolics profile. Our results showed that the biostimulation improved the antioxidant potential and the total concentration of phenolics in the bioEVOO and bio-pomace (bioPom) samples and mainly enhanced, among all classes of phenolic compounds, the production of the flavonoids and the secoiridoids. Moreover, they demonstrated the Trichoderma action in the mevalonate pathway to produce phenols for the first time. The decisive action of the Thricoderma on the production of phenolic compounds increases the economic value of the waste materials as a source of bioactive compounds useful for the pharmaceutical, cosmetic, and food industries.
