Studies about Ozone (O 3 ) application in sugarcane residues for ethanol production are ongoing. This study was undertaken to evaluate the use of ozone as a pretreatment to facilitate hydrolysis of sugarcane top leaves. In the first experimentation, sugarcane top leaves were subjected to ozone (62.37 mg O 3 min -1 over a three hour period) and water only (control). Following ozonation, the material was separated into a liquid and solid fraction. The analysis of liquid fraction showed that phenolic concentration and soluble solids did not vary. However, there was a decrease in pH and an increase in reducing sugars. This treatment increased saccharification. During the second treatment, ozone was added by direct infusion in a suspension of sugarcane top leaves and distilled water at a ratio of 1:10 (w.v -1 ). Additionally, the lignocellulosic analysis showed a positive relationship between the dose of ozone and decomposition of lignin and an increase in the proportion of cellulose and hemicellulose in the material. All aspects are good signs for the use of ozone in pretreatment of lignocelullosic feedstocks.
臭氧(o3)在甘蔗残渣中用于乙醇生产的研究正在进行中。本研究旨在评价臭氧作为预处理对甘蔗顶叶水解的促进作用。在第一次实验中，甘蔗顶叶只受到臭氧(62.37 mg O 3 min -1, 3小时)和水(对照)的影响。臭氧化后，物料被分离成液体和固体部分。液体组分分析表明，酚类物质含量和可溶性固形物含量没有变化。然而，pH值下降，还原糖增加。这种处理增加了糖化。在第二次处理中，以1:10 (w.v -1)的比例将臭氧直接注入甘蔗顶叶与蒸馏水的悬浮液中。此外，木质纤维素分析表明，臭氧剂量与木质素分解和材料中纤维素和半纤维素比例的增加呈正相关。所有方面都是使用臭氧预处理木质纤维素原料的良好迹象。

The canning industry in Brazil has supply problems, since the extractive fishing sardine does not meet industry demand, causing the need to import fish from other countries. In this context, there is the proposal to use the matrinxa (Brycon amazonicus) as an alternative to sardines (Sardinella brasiliensis) for the canning of fish industry. This work aimed to evaluate the nutritional and sensory quality and matrinxa cans in vegetable oil. To evaluate the acceptance we used three canned fish samples with vegetable oil coverage, as follows: matrinxa, freshwater and saltwater sardine sardines. A preference test and an acceptance hedonic scale of nine points was applied. There was no significant difference in preference between the matrinxa and freshwater sardines, however, the matrinxa and saltwater sardines differ significantly, and canned matrinxa was the most preferred. For the color attribute, flavor and overall impression there was no significant difference between the three fish, as for the taste attribute, matrinxa presented higher acceptance significantly differing from saltwater sardines. In the chemical composition, the matrinxa showed a protein content of 28.67%, moisture 51.67%, 15.67% and total lipids 2.67% minerals. Therefore, it is concluded that the matrinxa is a good option for canned fish industry, as presented good nutritional quality and high acceptance compared to traditional canned fish.

The present study aimed to evaluate the efficiency of the irradiation process in the control of Enterococci spp. and Escherichia coli in chilled chicken heart samples acquired in an industry located in the West Zone of Rio de Janeiro, Brazil, using irradiation doses of 1.5 kGy, 3, 0 kGy and 4.5 kGy. These microorganisms are related to fecal contamination, and are indicators of the sanitary processing conditions of the foodstuffs. The bacteriological analyses were conducted applying the methodologies and standards recommended by Brazilian norms resolution no. 12 (BRASIL, 2001) and instruction no. 62 (BRASIL, 2003) Regarding Escherichia coli, no statistically significant difference among the four groups (control, 1.5 kGy, 3.0 kGy and 4.5 kGy) was observed (p> 0.05). The Most Probable Number (MPN) for Enterococci spp. was not proven in the investigated samples. Thus, the Co60 gamma irradiation process was effective in eliminating Escherichia coli, and the lowest dose, of 1.5 kGy, was enough to abolish this enteropathogen from the evaluated samples.

The production of flowers and ornamental plants is an activity that has achieved great economic importance in several Brazilian states however in Paraiba State is little explored, which is intended to leverage with fertilization and water management. A trial was carried out in a greenhouse located at the Federal University of Campina Grande, in Campina Grande, Paraiba State, Brazil, with sunflower, cv Embrapa 122 V2000, in order to evaluate the effects of nitrogen, phosphorus, potassium and available soil water on the flowering this oil crop. A completely randomized design with 11 treatments originated from a baconian matrix was adopted. Reference doses were 60:80:80 kg ha-1 of N:P 2 O 5 :K 2 O, respectively and four available soil water (55, 70, 85 and 100% AW) in triplicate. Stem growth, head external and internal diameter and number of petals were measured when the flowers were fully open. While not affecting the number of petals, the highest percentage of available soil water promoted better benefit to the inflorescence of sunflower. Doses of 60 kg ha -1 N; 80 kg ha -1 P 2 O 5 e 80 kg ha -1 K 2 O provided better quality inflorescences.

Within the winemaking techniques, there are several resources available to enhance the quality of wines. Faced with the immense possibilities of combinations that can result in unique quality wines this study aimed to evaluate the effects and benefits of the ellagic tannins application in full or partial replacement of sulfur dioxide in the wines from the variety Merlot chemical properties. In these experiments, the following treatments were performed: T1 (control, traditional vinification with potassium metabisulfite addition - 20 g.hL -1 ); T2 (traditional wine without the potassium metabisulfite addition and without tannin addition); T3 (traditional wine with the ellagic tannin addition - 30 g.hL -1 ); T4 (traditional wine with the addition of 30 g.hL -1 ellagic tannin and potassium metabisulfite 10 g.hL -1 ). The treatments were evaluated after the end of the maceration, after the malolactic fermentation and after bottling. The results obtained in this study indicate that it is technically possible to produce Merlot young red wine without the addition of SO 2 . But more studies are needed to optimize the employed winemaking techniques and their relationship to the parameters evaluated.

Biodiesel is a renewable and sustainable fuel. In recent decades the growing demand for energy and environmental awareness generates great interest in obtaining alternative fuels from renewable resources, such as biodiesel. All highlighting the new fuel requires a thorough study of all the productive chain. Among the oil that stands out, the peanut is a promising alternative for obtaining biodiesel. In this sense this study conducted documentary research on the oil crop peanut ( Arachis sp.) Belonging to the biodiesel production chain, which is inserted in the National Agro-Energy Plan. Considering the vegetative, ecological and economic aspects of oilseed peanut regarding culture in the biodiesel production chain is of particular importance, due to be among the short cycle crops. However the economic viability becomes a standstill due to peculiarities involving the crop production system.

Edible coatings may contribute to extend the shelf life of fresh-cut fruits by reducing moisture and solute migration, gas exchange, respiration, and oxidative reaction rates, as well as by reducing physiological disorders. The objective of this study was to evaluate the effects of chitosan application associated with montmorillonite clay and essential oil of cloves in relation to chemical, physical, microbiological ( Escherichia coli , Salmonella and Yeast and Mold) and sensory attributes characteristics of melon ( Cucumis melo L. ) minimally processed when stored at 4±1°C. The melons were washed, peeled, seeds removed, diced, was applied coatings and then the cubes were stored in a PET (polyethylene terephthalate) packaging for a period of 7 days at 4±1°C. Analyses of pH, total soluble solids, titratable acidity, microbiological ( Escherichia coli , Salmonella , Molds and Yeasts) and sensory analysis (texture, color, aroma and overall assessment) were carried out. The analyses were performed in triplicate on the processing day (day 0) of the samples and after 1, 3, 5 and 7 days of storage. It can be concluded that the that coatings containing chitosan together with Montmorillonite clay and essential oil of clove (T3 and T4) were more efficient in conserving the physical and chemical characteristics of minimally processed melon when compared to the control sample and treatment contained only chitosan. The use of chitosan alone and together with montmorillonite and Clove essential oil were effective in maintaining the sensory and microbiological characteristics for a longer time.

The analyses were performed in triplicate on the processing day (day 0) of the samples and after 1, 3, 5 and 7 days of storage. It can be concluded that the that coatings containing chitosan together with Montmorillonite clay and essential oil of clove (T3 and T4) were more efficient in conserving the physical and chemical characteristics of minimally processed melon when compared to the control sample and treatment contained only chitosan. The use of chitosan alone and together with montmorillonite and Clove essential oil were effective in maintaining the sensory and microbiological characteristics for a longer time.","PeriodicalId":119762,"journal":{"name":"Journal of Bioenergy and Food Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131970628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The objective of this study was to develop a sensory characterization protocol employing the Quality Index Method (MIQ) for theen tire Mapara and stored on ice for 20 days and predict its shelf life. They collected 25 copies of Mapara with skin, eviscerated and kept in cool boxes stored with drinking ice until the end of the experiment. The selection and training of 12 judges who evaluated lots of Mapara every 5 days to establish the Quality Index Method (MIQ) parameters was performed. The Maparas were evaluated for surface appearance (stiffness, body color, palpation flesh firmness, color head, the bottom of the mouth), eyes (transparency of the eyeball, pupil and shape), gills (color and shape) and musculature (color and appearance of the fibers) during storage. The sum of the scores of the protocol was 26 demerit points, 14 points considering the superficial aspect, 6 eyes, 4 gills and 2 muscles. It was concluded that the MIQ protocol with 26 demerit points and 13 quality attributes was effective to evaluate the freshness and estimate the useful life of the species. And Mapara gutted and stored on ice kept their sensory characteristics assessed by Quality Index Method (MIQ) for 10 days.
本研究的目的是利用质量指数法(MIQ)对轮胎Mapara进行感官表征，并在冰上储存20天，并预测其保质期。他们收集了25只带皮的玛帕拉，取出内脏，放在装有饮用冰的冷盒子里，直到实验结束。选出并培训12名评委，每5天对大量的Mapara进行评估，以建立质量指数法(MIQ)参数。在储存期间，评估Maparas的表面外观(硬度，身体颜色，触诊肉硬度，头部颜色，口腔底部)，眼睛(眼球的透明度，瞳孔和形状)，鳃(颜色和形状)和肌肉组织(纤维的颜色和外观)。该方案的总得分为26分，考虑到表面，6眼，4腮和2肌肉的14分。结果表明，含有26个缺陷点和13个质量属性的MIQ方案可有效地评价品种的新鲜度和使用寿命。用质量指数法(Quality Index Method, MIQ)评价其感官特性，并将其去肠冷藏10 d。
