The relative abundance of almond seed in several tropical regions of the world coupled with the little knowledge of its utilization in vegetable oil production prompted the need for this review. The aim is to review almond oil expression through different extraction/expression approach, the economic and health benefits of almond oil, and the challenges and prospects of almond oil extraction in Nigeria. This review covers the recent significant materials found in the literature on almond seed and oil extraction/expression. Almond oil is an essential oil packed with a lot of nutrients that are beneficial to human health. Therefore, it is important to devise better approach for maximum oil extraction/ expression. |

Mauritia vinifera (buriti) is a palm tree that grows wild in different areas of Brazil, particularly in the Amazonian region. The buriti oil is rich in carotenoids, especially in β-carotene. The growing interest in other natural sources of β-carotene has stimulated the industrial use of buriti as a raw material for pulp oil extraction. Most processes are based on the conventional technologies, involving drying and pressing the pulp for oil recovery and further separation of carotenoids in a liquid phase using organics solvents. In the present work, the ethanol-based process was evaluated for simultaneous carotenoids recovering and fractionating from buriti pulp. The raw material and ethanol, 1:4 ratio, were placed in an erlenmeyer flask and maintained at... |

With the continuing controversy over genetically modified (GM) foods, some groups advocate mandatory labeling of these products, while other groups oppose labeling. An important issue is how GM labels affect consumers' willingness to pay for these food products in the market. Using a statistically based economics experiment with adult consumers as subjects, we examine how willingness to pay changes for three food products--vegetable oil, tortilla chips, and potatoes--when GM labels are introduced. Participants in the experiments discounted GM-labeled foods by approximately 14% relative to their standard-labeled counterparts. The evidence also showed that sequencing of food labels affects willingness to pay, and that randomizing treatments is an important... |

In combination with the emergence of genetically modified (GM) food, there has been an urgent call for GM labeling to provide relevant information disclosure. Using data collected in Beijing, China, this study attempts to address the issue of whether different types of information may have distinct impacts on consumers’ stated purchasing decisions. Three types of information are used in this study: one is generic and the other two are linked with two important implications of GM technology—human health and the environment. Results verify that consumers’ purchasing decisions are affected by different types of information through their attitudes and personal characteristics. This finding has potential implications for establishing various GM marketing... |

ABSTRACT The objective of this study was to evaluate the effect of three levels of crude cottonseed oil on performance, organ weights, and blood parameters of growing broilers. Carcass and cut yields after 33 and 42 days of age and the economic viability of the diets were also evaluated. Male broilers of the Ross line were distributed in a completely randomized design, in a 4 × 2 factorial arrangement (0, 2, 4, and 6% inclusion of cottonseed oil, with and without ferrous sulfate) with five replicates. In the period from 22 to 33 days, quadratic and increasing linear effects were observed on feed intake and weight gain, respectively. Feed conversion during the same period was better with the addition of ferrous sulfate. The addition of ferrous sulfate... |

Abstract This study aims to evaluate the physicochemical properties and tocopherol content in faveleira seed oil extracted using three methods (Bligh-Dyer, Soxhlet extractor, and cold-pressing). Each of the methods generated different yield percentages, with cold-pressing producing the least amount of oil. However, the cold-pressing method produced better quality oil with more desirable properties, including low acidity (1.56 ± 0.01% oleic acid) and low peroxide value (0.45 ± 0.09 mEq/1000 g). Cold-pressing resulted in higher quantities of tocopherols: 0.59 ± 0.12 mg/100 g of alpha-tocopherol and 20.97 ± 1.15 mg/100 g of beta + gamma-tocopherol. Faveleira seed oil, when extracted by cold-pressing, maintains better physicochemical quality, with the highest... |

ABSTRACT This experiment was conducted to evaluate growth performance and carcass characteristics of barrows from 25 to 100 kg fed diets with different dietary net energy (NE) levels. Seventy-two barrows with initial body weight (BW) of 25.19±2.13 kg were allotted using a completely randomized block design to one of six dietary NE treatments (2300, 2380, 2460, 2540, 2620, and 2700 kcal kg−1), which had two pigs per replicate and six replicates per treatment. Diets were formulated to be fed in three phases (25 to 60, 60 to 70, and 70 to 100 kg BW). The six different dietary NE densities were met by adding soybean oil in place of the inert ingredient (kaolin) to a corn-soybean meal-based diet. Increasing dietary NE decreased average daily feed intake and... |

The main ways by which extra-virgin olive oil is consumed include direct application on salads or as an ingredient in sauces, but it is also been used by some for cooking, including frying and baking. However, it has been reported that under heat stress, some nonglyceridic components of olive oil are degraded. So, the effect of heating (at 50, 100, 150, and 200 °C for 2 h) on the volatile composition and sensory aspects of extra-virgin olive oil were evaluated. Heating altered the volatile composition of extra-virgin olive oil, mainly at higher temperatures (above 150 °C). The main modifications were related to the formation of large amounts of oxidized compounds, particularly large chain aldehydes. Sensory aspects were also altered when the oil was heated... |

The effect of five adjuvants (non-ionic surfactant, paraffinic oil, vegetable oil, mixture of fatty acids methyl esters plus surfactant blend, and organosilicone) on diquat efficacy was assessed on poverty brome, sterile oat, and Italian ryegrass in field and pot experiments. All tank mixtures with diquat increased diquat efficacy from 50-54% to 77-98% as for fresh weight reduction, indicating significant enhancement of diquat efficacy on grasses. The increased efficacy was most likely attributed to better droplet retention and diffusion on the leaf surfaces. When combined with non-ionic surfactant, diquat showed slightly more rapid control of grass weeds (i.e. symptoms were visible within a few hours after application). |

The expression of the enzymatic system produced by basidiomycetous fungi, which is involved in the degradation of xenobiotics, mainly depends on culture conditions, especially of the culture medium composition. Trametes villosa is a strain with a proven biotechnological potential for the degradation of organochlorine compounds and for the decolorization of textile dyes. The influence of glucose concentration, addition of a vegetable oil-surfactant emulsion, nature of the surfactant and the presence of manganese and copper on the growth, pH and production of laccase, total peroxidase and manganese-dependent peroxidase activities were evaluated. In general, acidification of the medium was observed, with the pH reaching a value close to 3.5 within the first... |
