| Olive is one of the strategic products in Iran, and due to the significant cultivation area of this product, oil companies should be equipped with suitable processing equipment. Unfortunately, despite the high capacity of olive in Iran, oil companies are equipped with imported machines. In this study, the construction and evaluation of the Three-counter device of Iran has been developed. The machine has three oil, water and olive pulp outputs. In order to evaluate the machine, the amount of moisture content and fat extracted from the machine was checked at 2500 and 3500 rpm and 30 and 45% water content. Also, four different samples Manzallina, Fishemi, Kalamata and Oily were used in this experiment. The main components of the machine include an electric... |

| This study evaluated the effect of the processing and long-term storage on the antioxidant potential and activity of antioxidant enzymes of frozen purées from six acerola clones. Ripe acerolas from clones BRS 235, BRS 236, BRS 237, BRS 238, II47/1 and BRS 152 were harvested; the pulp was processed, packed in sealed polyethylene plastic bags and stored in a domestic freezer at -18°C for 11 months. Samples of each clone were analyzed on harvest/processing day and every 30 days after for bioactive antioxidant compounds, antioxidant enzyme activity and total antioxidant activity. Acerola purées presented a decrease of non-enzyme antioxidants and an increase of antioxidant enzymes activities, indicatives of a compensatory mechanism between enzymatic and... |

| Buriti and patawa are two endemic palm trees from the Amazon region. Their pulps are traditionally consumed by the local population, but are underused and lesser known worldwide. Nutritional composition, fatty acid and tocopherol contents of the two palm pulps were determined by modern analytical methods: Gas Chromatography (CG) and High Performance Liquid Chromatography (HPLC), based on the standards of AOCS (AMERICAN..., 2002) and AOAC (ASSOCIATION..., 1997), respectively. Buriti and patawa fruit pulps are highly nutritive, with respectively, high fat content (38.4% and 29.1% of dry matter (DM)), protein content (7.6% and 7.4% of DM) and dietary fibers (46% and 44.7% of DM). Buriti pulp can be considered healthy food due its high content of vitamin E... |

| Abstract The objective of this paper was to determine the volatile profile of four cultivars - Barker, Collinson, Fortuna and Geada of avocado (Persea americana, Mill.) fruit and to perform a detailed study on the effect of volatiles extraction conditions. The best conditions for extraction for Collinson and Fortuna cultivars were by using a mixture of pentane and ethyl ether (2:1) as solvent for 80 min, while for Barker and Geada cultivars, the solvents were hexane and pentane-ether (2:1), respectively but for a shorter extraction period of 60 min. A total number of 158 compounds were separated in all 4 avocado cultivars, among them eighty-four volatile compounds were identified. The principal volatile compounds viz. hexanal, ethyl acetate, methyl... |

| The objective of this paper was to determine the chemical composition of the avocado fruit of cultivars Fortuna, Collinson, and Barker and to carry out a detailed analysis of the fatty acid composition of the pulp, seed, and peel oils. The saturated fatty acid (SFA) of the pulp oils accounted for around 22.3, 29.4, and 41.3% of the total fatty acids in the Fortuna, Collinson and Barker cultivars, respectively, and these values indicate better quality of pulp oil of Fortuna and Collinson cultivars than that of the Barker cultivar. There was very little variation in the content monounsaturated fatty acids of the peel oils between the cultivars. However, the seed oil of the Collinson cultivar was the best since it contained the lowest (30.8% of total fatty... |

| Se estudió la influencia de las condiciones de cultivo (clima, riego o temporal y tipo de suelo) en la composición nutrimental de los tejidos del fruto (epicarpio, pulpa, testa y embrión) y en la remoción de nutrimentos por tejido y por tonelada de fruto fresco de los cvs. Ataulfo, Kent, Keitt y Tommy Atkins. Asimismo, en ‘Ataulfo’ y ‘Tommy Atkins’ se estudió la relación entre el contenido nutrimental en suelo, hojas, epicarpio y pulpa (materia seca) y pulpa fresca, con la calidad postcosecha. Se trabajó con árboles altamente productivos (producción superior a los 150 kg·árbol-1), seleccionados en el 2008 de los que se cosecharon frutos en madurez fisiológica. En la materia seca de cada tejido se determinó la concentración de: N, P, K, Ca, Mg, S, Fe, Cu,... |

| This paper aims to analyze the evolution of research and technological innovations that have taken in forest and pulp industrial areas, and emphasizes their possible impacts on the competitiveness of the Brazilian pulp industry. First, primary and secondary data are used to evaluate the main types of research and technological innovations and, in sequence, it is evaluated the importance of technological innovations that have contributed to the expansion of the Brazilian pulp industry in the pulp world market. Technological innovations in forest and industrial areas in the Brazilian pulp industry have brought significant increases of forest and industrial productivities, leading to reduction of pulp production cost. Consequently, profitability of the... |

| In previous literature, the degree of exchange rate pass-through to importing countrys currency has often been found to be incomplete, which supports the idea of imperfect competition in the forest products markets. In this study, exchange rate pass-through is examined by employing a mark-up model for the UK and German pulp and newsprint markets for 198697. Two specifications are compared, one where exchange rates in importing countries are employed and the other that attributes for the fact that US dollar is largely used in pricing for forest industry products in Europe. In contrast to previous studies, our estimates indicate very low degrees of pass-through, which is consistent with competitive European markets for pulp and paper. Consequently,... |
