The storage process, in some way, has a direct influence on the production and status of the derived final product. It was possible to verify in this case study that the storage system of the company is deficient, needing improvements, especially when entering the raw material for production. Such problems, such as impurities, broken and burned grains, are generated in the warehouse itself, due to lack of prudence and coordination. Findings that contradict the objective of storage that is the conservation of the particularities of the grains and that may detract from the attributes of the end product in terms of taste, physical and chemical characteristics and visual conditions. Among the possible causes of the disturbances are the lack of maintenance of the machines, inefficient aeration and thermometry gauging. As a suggestion, besides the improvements on the mentioned problems, the implantation of management and strategy of inventories, of programs and quality control, development of the producing agents, planning and methods of solution of problems. The decline in the quality of the raw material, corn, can result in chain effect, damaging the final product, thus damaging the financial results of the organization.

A espécie vegetal Rhamnus sphaerosperma var. pubescens, que é nativa no Brasil, apresenta um grande potencial farmacológico por ser enquadrada no gênero Rhamnus, e possui poucos estudos relatam suas propriedades biológicas, e ainda não foram descritos os parâmetros físico-químicos para o controle de qualidade da matéria-prima vegetal desta espécie. Sendo assim, neste trabalho, os parâmetros físico-químicos, como o teor de umidade, cinzas totais e insolúveis em ácido foram determinados pela primeira vez para esta espécie. Também foi realizada a prospecção fitoquímica, que indentificou a presença marcante de compostos antraquinônicos, que podem ser utilizados como marcadores químicos. Análises microquímicas também foram realizadas, e confirmaram características estruturais presentes em caules e folhas, que já haviam sido descritas na literatura em análises morfonatômicas. Os extratos e frações de caules e folhas deste vegetal também não apresentaram toxicidade em métodos preliminares em Artemia salina e hemólise, sendo, de maneira geral, conisderados atóxicos nestes métodos, o que permite a sequência com estudos farmacológicos e toxicológicos que comprovem a segurança e eficácia destes extratos, para a obtenção de medicamentos fitoterápicos.

<p>The artisan cheese production is an important income source for family farmers, however the lack of standardization and negligence in the preparation of the product generates a low quality cheese. The production of cheese of good quality finds some obstacles, because milk does not contribute in many ways to ensure the characteristics of the product. The aim of this study was to evaluate the physico-chemical characteristics of 20 Minas Frescal cheeses, of which 10 samples were artisanal and 10 have industrial production. The handmade cheeses were sold in street markets and all the samples had no labeling and sanitary inspection seal. The industrialized were obtained in supermarkets, all the 20 samples were acquired in Londrina-PR. The analyses performed were &nbsp;moisture, fat (d.b.), pH and acidity. The fat analysis showed that 50% of samples from artisanal cheeses and 40% of industrialized ones violate the current laws. The pH of artisanal cheese samples ranged between 5.2 and 6.7 and the acidity ranged between 0.06 and 2.41%. The variation in acidity showed that the cheeses are made without standard and quality control of raw material. In industrialized cheeses the pH ranged between 5.3 and 6.5 and acidity between 0.2 and 1.4%. With this work we concluded that the small producers and industries do not pay attention to physico-chemical parameters essential to the quality of the cheese.</p><p>&nbsp;</p><p>DOI: http://dx.doi.org/10.14685/rebrapa.v2i2.48</p>

Yerba mate is a Brazilian native species; its importance is due to cultural, environment, and economic factors. Species seedlings production needs to be improved, evaluating alternative substrates and containers. Therefore, we evaluated growth and quality of yerba mate seedlings produced on organic waste-based substrates in biodegradable and non-biodegradable containers. Commercial substrates based on pine bark (CS) and components based on sewage sludge (SS) and coal residue (granulometry from 1 to 3 mm - CR) were used. For each container, were prepared treatments with different substrate components: 75CS/25CR, 50CS/50CR, 25CS/75CR, 75CS/25SS, 50CS/50SS, 25CS/75SS, and CS. Substrates were submitted to physical and chemical analysis. The containers used were 110 cm³ polypropylene tubes, 500 cm³ polyethylene plastic bags, 460 cm³ paperpot®, and 460 cm³ TNT (non-woven fabric). Total height, stem diameter, shoot, and root dry biomass at the end of the seedlings production period were measured and total dry mass, Dickson quality index and height/diameter ratio were calculated. All containers used with commercial substrate provided satisfactory seedlings growth. The substrates showed distinct physical and chemical characteristics due to the addition of sewage sludge and coal residue, which resulted in higher pH and lower seedlings growth. Physical and chemical characteristics of substrates influenced growth and quality of yerba mate seedlings and the alternative substrates used in this study are not suitable to produce seedlings of the species on these conditions. The containers did not influence the variables used in this study.

The guava (Psidium guajava L.) is a fruit plant that is widely distributed in Brazil. In the state of Mato Grosso, the culture adapted well in an irrigated system, however, there are still few studies related to the quality of the fruits produced in the state. In this way the objective of this work was to evaluate the physical and chemical characteristics of guava fruits cultivated in the region of Tangará da Serra - MT and establish the correlation between these characteristics. A randomized complete block design with three cultivars (Rica, Ogawa and Paluma) was used, four replications with six plants, where the following characteristics were evaluated: fresh mass, length, diameter, length / diameter ratio, pulp percentage, Total soluble solids, titratable total acidity, pH and ratio. The fruits of the cultivars Paluma, Rica and Ogawa cultivated in Tangará da Serra-MT have quality both for the in natura market and for the industry, in addition, a correlation of the physical and chemical characteristics of the guava fruits was observed, allowing the use Of simpler feature evaluations to aid the selection process.

Study on the water quality of Sentani Lake has been carried out during October–November 2012 at 3 stations of observation. Observation and retrieval of macrobenthos have been done by using combination between line transect method and square plot. While for physical and chemical  characteristics of water is measured in site and at laboratory. Index of variance Shannon-Wiener, Evenness and Density as well as Pollution Index were used to analyse the physical and chemical  characteristics of water. Result of this study showed that Telaga Maya  area (station 3) has  the highest variation of macrobenthos with H’ value= 2.12 while the lowest variation (H’= 1.66) was found around Ekspo River (station 2). Based on population density of macrobenthos, Pilsbryoconcha exilis which collected in the area of Jembatan Dua River (station 1) was found as  the highest population with density 9.26 ind/m2, while the lowest population density was Melanoides tuberculata with density 0.93 ind/m2. It can be concluded that based on the value of variance index and Pollution Index, the water quality of Sentani Lake belong to low-medium polluted category.Key words: water quality, macrobenthos, sentani lake and Jayapura.
