Label authentication of monovarietal extra virgin olive oils is of great importance. A novel approach based on a potentiometric electronic tongue is proposed to classify oils obtained from single olive cultivars (Portuguese cvs. Cobrançosa, Madural, Verdeal Transmontana; Spanish cvs. Arbequina, Hojiblanca, Picual). A meta-heuristic simulated annealing algorithm was applied to select the most in...

Dehydrated citrus pulp and citrus pulp-protein supplements were evaluated as potential supplements for a preconditioning program. The supplements compared were no supplement, citrus pulp alone, citrus pulp with urea, and citrus pulp with added UIP. Supplemented cattle produced greater gains than unsupplemented cattle. Citrus pulp with added UIP produced the greatest ADG (0.95 lb/hd/d) whereas c...

Olive (Olea europaea), whose importance is mainly due to nutritional and health features, is one of the most economically significant oil-producing trees in the Mediterranean region. Unfortunately, the increasing market demand towards virgin olive oil could often result in its adulteration with less expensive oils, which is a serious problem for the public and quality control evaluators of virg...

Thermophilic mannanase from the Bacillus sp. MG-33 was applied on wheat straw-rich-soda pulp to evaluate its bleaching potential. Optimum conditions for bio-bleaching of pulp were found as, mannanase 3Ug -1 of pulp at pH 6.5 and temperature 65oC that enhanced the brightness by 30% and reduced the kappa number by 20% within 2h. Tear index (1.1, points) and burst index (0.02, points) were also im...

BACKGROUND Virgin olive oils are richer in phenolic content than refined olive oil. Small, randomized, crossover, controlled trials on the antioxidant effect of phenolic compounds from real-life daily doses of olive oil in humans have yielded conflicting results. Little information is available on the effect of the phenolic compounds of olive oil on plasma lipid levels. No international study w...

The present study investigated the dietary impact of dried olive pulp (OP) on growth performance, gut health and some welfare behavior characteristics broilers. It was conducted in a commercial poultry farm using 108 13 day-old Ross male Chickens were equally randomly assigned to 3 treatments, CON, OP3 OP6, based incorporation rate OP ration (0%, 3%, 6%, respectively). A beneficial foot pad der...

An increase in the land area dedicated to super-high density olive orchards has occurred in Chile in recent years. Such modern orchards have high irrigation requirements, and optimizing water use is a priority. Moreover, this region presents low water availability, which makes necessary to establish irrigation strategies to improve water productivity. An experiment was conducted during four con...

Olive fruit fly trap measurements are used as one of the indicators for olive grove infestation, and therefore, as a consultation tool on spraying parameters. In this paper, machine learning techniques are used to predict the next olive fruit fly trap measurement, given as input environmental parameters and knowledge of previous trap measurements. Various classification algorithms are employed ...

Olive, as a fruit, cannot be consumed directly due to the oleuropein substance it contains and needs to be processed into either table olives or olive oil through various production systems. Th e process of olive oil extraction results in olive oil as the main product, and two by-products, with olive pomace being one and brown-coloured Olive Mill Wastewater (OMWW) as the other. OMWW has no dire...
