Antioxidant activity of oils extracted from orange (Citrus sinensis) seeds Anais da ABC (AABC)
Jorge,Neuza; Silva,Ana Carolina da; Aranha,Caroline P.M..
Due to the increasing production of food in the world with consequent increase of the production of waste, the importance of developing researches for its use is noticed. Thus, the interest in vegetable oils with bioactive compounds, such as the ones extracted from fruit seeds, is growing. Therefore, the present study aims to characterize the oils extracted from seeds of Hamlin, Natal, Pera-rio and Valencia orange varieties (Citrus sinensis), as to the levels of total carotenoids, total phenolic compounds, tocopherols and phytosterols, as well as to determine their antioxidant activity. The orange seed oils presented important content of total carotenoids (19.01 mg/kg), total phenolic compounds (4.43 g/kg), α-tocopherol (135.65 mg/kg) and phytosterols...

Assessing the Demand for a Functional Food Product: Is There Cannibalization in the Orange Juice Category? AgEcon
Yuan, Yan; Capps, Oral, Jr.; Nayga, Rodolfo M., Jr..
The demand for functional foods has increased notably in recent years due to growing consumer interest in diet and health issues. Currently, the food industry is introducing many types of new food products with functional attributes. Consequently, cannibalization is a critical issue for firms that offer multiple products within a certain product category. The identification and assessment of cannibalization are integral factors when making strategic decisions about new product introductions. Using scanner data from Information Resources, Inc. (IRI), pertaining to a particular functional food, namely a phytosterol-enriched product for orange juice, we find that no cannibalization effects exist with respect to its introduction. We also provide estimates of...

Characterization of constituents, quality and stability of pomegranate seed oil (Punica granatum L.) Ciênc. Tecnol. Aliment.
MELO,Illana Louise Pereira de; CARVALHO,Eliane Bonifácio Teixeira de; SILVA,Ana Mara de Oliveira e; YOSHIME,Luciana Tedesco; SATTLER,José Augusto Gasparotto; PAVAN,Rosângela Torres; MANCINI-FILHO,Jorge.
Abstract This study aimed to characterize pomegranate seed oil and evaluate its quality and stability parameters against those of linseed oil. The profile of fatty acids and phytosterols and the content of tocopherols were analyzed by gas chromatography and high performance liquid chromatography, respectively. The quality of both oils was assessed as recommended by the American Oil Chemists' Society (AOCS) and stability was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH), β-carotene bleaching (coupled oxidation of β-carotene/linoleic acid) and Rancimat® assays. While α-linolenic acid (52%) was the most abundant fatty acid in linseed oil (LO), punicic acid (55%) was highest in pomegranate seed oil (PSO). Tocopherols and phytosterols (175 and 539 mg/100...

Comparative analysis of fatty acids, tocopherols and phytosterols content in sunflower cultivars (Helianthus annuus) from a three-year multi-local study Phyton
Ayerdi Gotor,A; Berger,M; Labalette,F; Centis,S; Daydé,J; Calmon,A.
Sunflower oil is naturally rich in both unsaturated fatty acids and numerous minor components, with high levels ofa-tocopherol and phytosterols that could play an important role in plant protection. These micronutriments, tocopherols and phytosterols, also exhibit health benefits for humans including reducing both cardiovascular diseases and aging disorders. a−Tocopherol represents more than 95% of total sunflower tocopherol and has the greatest vitaminic activity. Furthermore, this oil contains high amounts of β-sitosterol which is a promising health beneficial phytosterol. The objective of this study was to compare the content and composition of fatty acids, tocopherols and phytosterols in sunflower oil between different cultivars and...

Further insights into the latex metabolite profile of Ficus carica IPB - Escola Superior Agrária
Oliveira, A.P.; Silva, L.R.; Andrade, P.B.; Valentão, P.; Silva, B.M.; Gonçalves, Rui; Pereira, J.A.; Pinho, P. Guedes de.
Latex is a sticky emulsion that exudes upon damage from specialized canals from several plants. It contains several biologically active compounds, such as phytosterols, fatty acids, and amino acids. In plants, these compounds are involved in the interaction between plants, insects, and the environment. Despite its chemical, biological, and ecological importance, Ficus carica latex is still poorly studied. To improve the knowledge on the metabolite profile of this matrix, a targeted metabolite analysis was performed in a representative sample from F. carica latex. Seven phytosterols were determined by gas chromatography-ion trap mass spectrometry (GC-ITMS) and high-performance liquid chromatography coupled to diode array detection (HPLC-DAD), with...

Influence of food components on lipid metabolism: scenarios and perspective on the control and prevention of dyslipidemias Ciênc. Tecnol. Aliment.
Frota,Karoline de Macedo Gonçalves; Matias,Andrea Carvalheiro Guerra; Arêas,José Alfredo Gomes.
Cardiovascular diseases (CVD) are the main causes of death in the Western world. Among the risk factors that are modifiable by diet, for reducing cardiovascular disease risks, the total plasma concentrations of cholesterol, triglycerides, LDL-C, and HDL-C are the most important. Dietary measures can balance these components of the lipid profile thus reducing the risk of cardiovascular diseases. The main food components that affect the lipid profile and can be modified by diet are the saturated and trans fats, unsaturated fats, cholesterol, phytosterols, plant protein, and soluble fiber. A wealth of evidence suggests that saturated and trans fats and cholesterol in the diet raise the total plasma cholesterol and LDL-C. Trans fats also reduce HDL-C, an...

Oleic conversion effect on the tocopherol and phytosterol contents in sunflower oil Phyton
Ayerdi Gotor,A; Berger,M; Labalette,F; Centis,S; Daydé,J; Calmon,A.
In sunflower, conventional breeding is widely used for the modification of traits such as the fatty acid composition, disease resistance, and mainly for obtaining commercial oil with high oleic acid content. There is a growing interest on tocopherols and phytosterols present in sunflower, due to their human health benefits. This emphasizes the need of studies on breeding programs for these bioactive components. A hundred of isogenic pairs of classic and its oleic version of hybrids and parental lines were cultivated in different locations in France between 2003 and 2006. The results indicated that sunflower oil is rich in α-tocopherol and β-sitosterol. However, there was little correlation between traditional linoleic and oleic sunflower...

Sapucaia nut (Lecythis pisonis Cambess) and its by-products: a promising and underutilized source of bioactive compounds. Part I: nutritional composition and lipid profile. Repositório Alice
DEMOLINER, F.; POLICARPI, P. de B.; RAMOS, J. C.; BASCUÑAN, V. L. A. F.; FERRARI, R. A.; JACHMANIÁN, I.; CASAS, A. de F. de; VASCONCELOS, L. F. L.; BLOCK, J. M..
The nutritional composition of the sapucaia nut, cake and shell, the nut and cake minerals content and the lipid profile of the nut oil (fatty acids, tocopherols, phytosterols and triacylglycerols) were determined. The nuts and cake exhibited a high content of lipid (47.9 to 60.8 mg 100 g-1), protein (15.8 to 19.5 mg 100 g-1), dietary fiber (16.5 to 22.6 mg 100 g-1) and provided an excellent source of selenium (26.4 to 46.94 μg g-1). The oil contained a high amount of unsaturated fatty acids (39.7 to 45.4% of oleic and 32.2 to 46.6% of linoleic acids) and presented a high Oxidative Stability Index (8.57-12.95 h) indicating the presence of antioxidant compounds in the oil. The major triacylglycerols in the sapucaia oil were LLO, PLO, LOO, POO, OOO,...

Use of the spray chilling method to deliver hydrophobic components: physical characterization of microparticles Ciênc. Tecnol. Aliment.
Alvim,Izabela Dutra; Souza,Fabrizia da Silva de; Koury,Isabela Paes; Jurt,Thais; Dantas,Fiorella Balardin Hellmeister.
Food industry has been developing products to meet the demands of increasing number of consumers who are concerned with their health and who seek food products that satisfy their needs. Therefore, the development of processed foods that contain functional components has become important for this industry. Microencapsulation can be used to reduce the effects of processing on functional components and preserve their bioactivity. The present study investigated the production of lipid microparticles containing phytosterols by spray chilling. The matrices comprised mixtures of stearic acid and hydrogenated vegetable fat, and the ratio of the matrix components to phytosterols was defined by an experimental design using the mean diameters of the microparticles as...
