Experimental Study to Support Local Sunflower Oil Chains: Production of Cold Pressed Oil in Central Italy

et al. 2019

Sunflower is one of the most important oilseed crops cultivated in the world for different purposes. In Italy, the production is mostly located in the central area, representing 70% of Italian production. The market demand for sunflower oil is higher than the national production. There is an increasing request for cold pressed sunflower oil for food application. The success of this activity is linked to a correct setting up and management of the production and supply chain with a valorization of products and by-products. To this aim, information is needed, and this paper is focused on the cultivation of sunflower in central Italy using suitable hybrids, as well as on the study of the cold extraction performance of the sunflower seed produced and the quality of by-products and residues. Results indicate that, on average, a range of about 1.0-1.5 t ha −1 of cold pressed oil and different amounts of by-products can be obtained. According to a proposed scenario, 30 ha cultivated with sunflower are needed to create a complete supply chain within the farm, avoiding many additional passages and maintaining all the value for the farmer. It is important to use suitable hybrids for obtaining good yield, but also the cold extraction performances are important because they also affect the quality of by-products and residues that can be valorized themselves to improve sustainability.

“…The ultimate pH in the two treatment groups, however, was on the lower end of the recommended pH of a good quality meat, which is usually from 5.4 to 5.7 (Kerry & Ledward, 2009). Although there was no apparent variation the two treatments, it has generally been concluded that the rates of muscle pH and temperature decline and the pH-temperature interaction during the immediate postmortem period may have a significant effect on meat tenderness (Xazela et al, 2012;Kannan et al, 2006).…”

The objective of the study was to determine the meat quality responses of weaner steers fed diets containing potassium humate (PH) in a feedlot. Twenty-two yearling male steers were randomly allocated to two treatments: control (n = 11), fed a standard feedlot diet and PH (n = 11), fed a standard diet with added PH (5.8g/kg feed). The steers were housed in individual stanchions, with each steer as the experimental unit. At the end of the feeding trial at Day 112, the steers were slaughtered and the m. longissimus thoracic et lumborum muscle was sampled for meat quality measurements. Results of the study showed that diet had no effect on carcass characteristics and meat quality measurements, apart from meat pH and shear force values. Meat pH decline was more pronounced in the control group and higher shear force values were observed in the control group (6.58 and 4.91 kg) than the PH group (5.12 and 4.14 kg) at Day 1 and Day 7 of measurement respectively. The total intramuscular fat (IMF) was higher (by 16%) in the PH-fed weaner steers compared with the control. With regard to saturated fatty acids (SFA), higher amounts of myristic acid and heneicosanoic acid were observed in the PH-fed steers than in the control. However, the control had higher amounts of eicosatrienoic acid and eicosatetraenoic acid. PH inclusion in steer diets could therefore provide an alternative growth promotant in the production of safe and healthier meat in the feedlot. ______________________________________________________________________________________

Herbaceous Oil Crops, a Review on Mechanical Harvesting State of the Art

2020

The sustainable production of renewable energy is a key topic on the European community’s agenda in the next decades. The use of residuals from agriculture could not be enough to meet the growing demand for energy, and the contribution of vegetable oil to biodiesel production may be important. Moreover, vegetable oil can surrogate petroleum products in many cases, as in cosmetics, biopolymers, or lubricants production. However, the cultivation of oil crops for the mere production of industrial oil would arise concerns on competition for land use between food and non-food crops. Additionally, the economic sustainability is not always guaranteed, since the mechanical harvesting, in some cases, is still far from acceptable. Therefore, it is difficult to plan the future strategy on bioproducts production from oil crops if the actual feasibility to harvest the seeds is still almost unknown. With the present review, the authors aim to provide a comprehensive overview on the state of the art of mechanical harvesting in seven herbaceous oil crops, namely: sunflower (Heliantus annuus L.), canola (Brassica napus L.), cardoon (Cynara cardunculus L.), camelina (Camelina sativa (L.) Crantz), safflower (Carthamus tinctorius L.), crambe (Crambe abyssinica R. E. Fr.), and castor bean (Ricinus communis L.). The review underlines that the mechanical harvesting of sunflower, canola and cardoon seeds is performed relying on specific devices that perform effectively with a minimum seed loss. Crambe and safflower seeds can be harvested through a combine harvester equipped with a header for cereals. On the other hand, camelina and castor crops still lack the reliable implementation on combine harvesters. Some attempts have been performed to harvest camelina and castor while using a cereal header and a maize header, respectively, but the actual effectiveness of both strategies is still unknown.
