The peels of avocados, like other fruit peels, are commonly discarded, not knowing their potential use. In order to reuse avocado peel, the chemical and mineral compositions, total phenolic flavonoid contents as well antioxidant activities have been investigated by DPPH (1,1-diphenyl-2-picrylhydrazyl) FRAP(ferric-reducing power) methods in natura dehydrated peel. Dehydrated avocado-peel tea was manufactured activity evaluated, compound contents, compared with teas marketed. Avocado...
Leaves of a new variety Stevia rebaudiana with high content rebaudioside A were pretreated ethanol. The ethanolic extract showed antioxidant potential and 39 compounds identified, by UPLC/HRMS, among them one not yet mentioned in the literature for stevia leaves. From natura leaves leaves, conditions aqueous extraction steviol glycosides investigated using response surface methodology. extracts obtained purified ion exchange chromatography techniques membrane separation methods. recuperation...
A fast, easy lipid extraction method using low-toxicity solvents is developed in this study for oilseed samples rich polyunsaturated fatty acid.
This aim of this study was to characterize five varieties avocado for their proximal composition, physical properties, fatty acids antioxidant capacity, carotenoids and minerals. Quintal variety presented the best result total lipids, All a predominance monounsaturated (60%). The major acid oleic acid. Among analyzed, Breda had greater activity results FRAP (145%) DPPH (1.1200 µmol TE/g) assays, higher values ABTS analysis, Ouro Verde better ORAC assay (23%), Margarida L-ORAC analysis (200 ET/g).
This study evaluated the effect of feed supplementation with chia and canola oils as a substitute for soybean oil on composition Nile tilapia muscle tissue using chemometrics. Diets were supplemented 2.1% each provided to fish 15 30 days. Compared oil, significantly increased (P < 0.05) contents eicosapentaenoic acid (EPA, 20:5n-3), docosapentaenoic (DPA, 22:5 n-3), docosahexaenoic (DHA, 22:6 n-3) in fillet. At days, DHA content 97% fed 91% treatment oil. The highest EPA correlated (7.33 mg...
The need for a sustainable aquaculture is increasing the use of plant ingredients in replacement to fishmeal and fish oil diets tambaqui Colossoma macropomum, which leading not detectable levels docosahexaenoic acid (DHA) its flesh. We evaluated effect finishing diet supplemented with 5% microalgae meal from Schizochytrium sp. (MD) on growth, proximal composition fatty content flesh, comparing it non-supplemented diet. One hundred sixty-two (489.67 g) were distributed into six tanks (2,000...
The objective of this study was to evaluate the centesimal composition, fatty acid profile and nutritional quality index four seafood species: pink shrimp (Penaeus brasiliensis), Pacific white (Litopenaeus vannamei), mussel (Perna perna) octopus (Octopus vulgaris), that were collected in Santa Catarina, Brazil. lipid fraction evaluated by thrombogenicity (IT), atherogenicity (IA) hypocholesterolaemic acids-to-hypercholesterolaemic acids ratio (h/H). All studied species presented a high...
This study aimed to evaluate the effects of supplementation flaxseed oil and/or vitamin E on dry matter (DM) and nutrient digestibility, milk composition, fatty acid antioxidant capacity in buffalo milk. Four crossbred female dairy water buffaloes (97 ± 22 days milk; 6.57 2.2 kg milk/day, mean SD) were distributed a 4 × Latin square design, with 2 factorial arrangement (with or without at 25 g/kg matter; 375 IU/kg matter). The experimental period was divided into four periods 21 each (16 for...
<p><em>The passion fruit is one of the most produced in Brazil as well being highly functional power consumed due, however, their waste (peel and seed) are often discarded, causing a lot problems. Thus, to add value was evaluated antioxidant activity (phenolic compounds, flavonoids, DPPH FRAP) seed peel (in natura, dehydrated lyophilized) drying optimizing methods for this analysis. The kiln process not concentrated compound showed similar values natura peel, lyophilized obtained...
Several health benefits have been attributed to conjugated linolenic acid isomers (CLnA). In this study, the diet for Nile tilapia was supplied with pomegranate seed oil (at 2.1%) as source of CLnA. The provided fish 15 and 30 days. punic (40.58-53.77 mg g-1 total lipids) incorporated into fillet after days experiment, respectively. When compared control diet, level saturated fatty acids in were slightly increased. No change amount monounsaturated observed. effective transference CLnA tilapia.
