This study aimed to determine the antioxidant activity, total phenolic compounds and color in avocado 'Hass' hydrothermally treated. The fruits were hydrothermally treated at 45 degrees C for 5, 10, 15 and 20 min. After treatment, fruit were stored at room temperature (21 +/- 1 degrees C and 70 +/- 5% relative humidity) and cold (10 degrees C +/- 1 and 90 +/- 5% relative humidity). The fruits were analyzed for their antioxidant capacity by DPPH method and phenolic compounds at 0, 3, 9 and 12 days. The fruits color was measured at 0, 3, 6, 9, 12 and 15 days. The control fruits had higher antioxidant capacity and content of phenolic compounds during the storage period, compared to the fruits hydrothermally treated. The hydrothermally treatment altered the behavior as for the maintenance of the antioxidant activity in relation to the fruits control. In spite of superior values of antioxidant activity for the fruits maintained at 21 +/- 1 degrees C and 70 +/- 5% relative humidity, those refrigerated presented better aspect for commercialization. The refrigerated fruits presented better aspect for commercialization in relation to the maintained under room temperature. The brightness, color a * and b * values decreased with the storage days. Values color superiors were observed for the fruits control and those maintained under refrigeration. As it increased the irradiation dose reduced the fruits antioxidant activity and coloration.

New patterns from replaceable sources have been searched by scientific community to ethanol produce. The seed of avocado has thereabout 20% of starch. The starch hydrolysis results fermentable sugars by Saccharomyces cerevisiae, and the ethanol is the major product of fermentation. The starch can be hydrolysed by acids, basis and enzymes. Previous studies showed that enzymatic hydrolysis can produce 26,01 liter of ethanol per ton of seed. At the present work, we analyzed the chemistry hydrolysis efficiency before the enzymatic hydrolysis and the use of dormant seed consequence. The Brix rate variation at each stage was evaluated and the ethanol concentration was determined with gas chromatograph technique. The chemistry hydrolysis with subsequent enzymatic hydrolysis was effective, producing until 61,8 L.ton-1. The use of dormant seeds wasn’t significative to raise the Brix rate. The seed of avocado demonstrated to be an alternative replaceable source to ethanol produce

O objetivo desse estudo foi avaliar diferentes métodos de secagem de folhas para três diferentes frutíferas (maracujá, pêssego e abacate), com relação à determinação da matéria seca e os teores foliares de macronutrientes. Foram coletadas amostras de folhas recém expandida de três culturas, do pomar da fazenda de ensino e pesquisa da FCAV-UNESP, câmpus de Jaboticabal, no mês de janeiro de 2010, coletando-se para cada cultura 12 amostras com 25 folhas cada. Os tratamentos constituíram-se por dois métodos de secagem, estufa de circulação de ar forçada regulada a uma temperatura de 70°C e o forno microondas (FMO). Avaliou-se a massa da matéria seca e os teores foliares de macronutrientes. Os resultados sugerem que os dois métodos de secagem testados se assemelham na determinação de matéria seca e nos teores foliares de macronutrientes para as culturas análisadas, exceto os teores de cálcio na cultura do pêssego.
