Abstract
Over 7 million tonnes of solid Olive Oil Waste are produced in the Mediterranean each year [1], however the European Union does not provide specific provisions or regulations for the processing or disposal of Olive Mill Wastes [2]. Known as Olive ‘Pomace’, these wastes are an environmental hazard. The current waste management practices in the olive oil sector result in environmental problems such as soil contamination, underground seepage, water-bodies pollution and foul odor emissions [3]. Olive Waste treated in Pomace factories produces air pollution while having a low caloric fuel value of 20 MJ/kg which is less than coal, and over 50% less than natural gas and oil [4]. Attempts to use Olive Waste as an animal feed while showing a variety of benefits have been shown not to be commercially viable due to problems with Digestibility, Palatability and Safety [5,6]. The Olive Feed Corporation have invented a proprietary cooking process which solves the issues of Digestibility, Palatability and Safety that have previously prevented the successful commercial establishment of Olive Waste or Olive ‘Pomace’ as an animal feed. The final meat product known as “Olive Fed Wagyu’ showed significant improvements in flavour, texture andoverall eating experience, while also delivering an increase in revenue to the farmers producing the meat.
Highlights
With Olive Waste considered to be a critical problem in all Olive Oil production countries and the Mediterranean, and without uniform guidelines of disposal and use from country to country it poses a significant threat to the environment and the Olive Oil production industry as a whole
In California 25 Fullblood Wagyu cattle were fed with an Olive Feed supplement for a 4 month period using the feeding plan provided in Figure 1 vs a control group
In California, 25 Fullblood cattle were fed on a mixture of Olive Feed, grass and a high carbohydrate pellet to mix with the Olive Feed vs a control group solely fed on grass. 24 of the 25 Olive Fed cattle were graded as “Prime+” on the US grading scale. 12 taste tests were conducted with the Olive Fed meat compared to the solely grass fed meat
Summary
With Olive Waste considered to be a critical problem in all Olive Oil production countries and the Mediterranean, and without uniform guidelines of disposal and use from country to country it poses a significant threat to the environment and the Olive Oil production industry as a whole. In Putten, Holland 7 Fullblood Wagyu Cattle were fed with an Olive Feed supplement for a 4 month feeding period using the feeding plan provided in Figure 1 vs a control group. In California 25 Fullblood Wagyu cattle were fed with an Olive Feed supplement for a 4 month period using the feeding plan provided in Figure 1 vs a control group. In California overall feed composition analysis, marble score analysis, along with blind taste and texture tests were completed In this case, existing customers familiar with the flavor and texture profile of the farms meat produced without Olive Feed were chosen to perform the taste test, and compare flavour and texture in comparison with the farms Olive Fed Wagyu. The cattle were fed on a diet of Maize, Rolled Barley, and Straw, with Olive Feed substituted for Barley in the Olive Fed steer
