Rapeseed (canola) oil and other monounsaturated fatty acid-rich vegetable oils

Rapeseed (canola) and other monounsaturated fatty acid (MUFA)-rich oils are viewed as good candidates to replace, at least partially, the fish oil normally included in aquaculture feeds (aquafeeds). In fact, their utilization as a dietary lipid source for aquatic animals has some advantages over other readily available terrestrial alternative oils and fats; however, this is not without difficulties. MUFA are, indeed, easily digestible and a good source of available energy, and their deposition into fish flesh is considered to be less detrimental than other fatty acid classes, from a human nutritional viewpoint. This chapter attempts to review the principal information available regarding the utilization of MUFA-rich vegetable oil (VO) in aquaculture feed. Initially the chapter focuses on the rapeseed oil eRa) industry, agronomy, quality improvement, processing, and uses, and the main chemical and physical characteristics of rapeseed oil and other MUFA-rich va such as olive oil, peanut oil, and rice bran oil, amongst others. Following this, the potential advantages and challenges of using these alternative oils in the aquaculture feed industry are presented and discussed.

Characterization of the Pulp and Kernel Oils from Syagrus oleracea, Syagrus romanzoffiana, and Acrocomia aculeata

Vegetable oils are important sources of essential fatty acids. It is, therefore, important to characterize plant species that can be used as new oil sources. This study aimed to characterize the oils from guariroba (Syagrus oleracea), jeriva (Syagrus romanzoffiana), and macauba (Acrocomia aculeata). The physicochemical characterization was performed using official analytical methods for oils and fats, free fatty acids, peroxide value, refractive index, iodine value, saponification number, and unsaponifiable matter. The oxidative stability was determined using the Rancimat at 110 degrees C. The fatty acid composition was performed by gas chromatography. The results were submitted to Tukey's test for the medium to 5% using the ESTAT program. The pulp oils were more unsaturated than kernel oils, as evidenced by the higher refractive index and iodine value, especially the macauba pulp oil which gave 1.4556 and 80 g I(2)/100 g, respectively, for these indices. The kernel oils were less altered by oxidative process and had high induction period, free fatty acids below 0.5%, and peroxide value around 0.19 meq/kg. The guariroba kernel oil showed the largest induction period, 91.82 h.

Characterization and fatty acids profile of the oils from Amazon nuts and walnuts: Characterization and fatty acids profile of the oilseeds

Purpose: The purpose of this paper is to characterize oils extracted from Bertholletia excelsa, Lecythis pisonis, Dipteryx lacunifera, Carya illinoensis and Juglans regia, regarding their characterization and fatty acid profile. Design/methodology/approach: The oils were extracted from oilseeds by cold pressing and physico-chemical characterization was performed by using standard methods for oils and fats. The oxidative stability and fatty acid profile also were determined. Findings: According to the results, the physico-chemical properties of oils from nuts and walnuts were comparable to those of good quality conventional oils. The oil seeds are a good source of unsaturated fatty acids, especially oleic and linoleic acids. Research limitations/implications: Implies the identification of fatty acid profile and physico-chemical properties of oils extracted from nuts and walnuts, and to prevent certain types of diseases. Originality/value: The paper identifies a new source of essential fatty acids extracted from oilseeds. © Emerald Group Publishing Limited.

Thermophysical properties of cotton, canola, sunflower and soybean oils as a function of temperature

Vegetable oils are used in the industry of processed food, including deep-fat frying. This work determined data on the thermophysical properties of cotton, canola, sunflower, corn, and soybean oils. Thermal conductivity, heat capacity, density, and viscosity were measured within the temperature range of 299.15-433.15 K. The data showed that the temperature influenced the thermophysical properties of the oils studied. The developed correlations could be used to predict these properties within the range of temperatures studied. © 2013 Copyright Taylor and Francis Group, LLC.
