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.

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.

The objective of this present study was to investigate the effect of feeding fermented mixture of papaya leaf and seed meal (FERM) on the physical and chemical characteristics of meats of the Indonesian indigenous crossbred chicken (IICC). The study was carried out with 300 day-old IICC. The chicks were randomly distributed to five treatment groups, i.e., CONT (control diet based on corn-soybean- diet), FERMA (diet containing 1% FERM), FERMB (2.5% FERM), FERMC (5% FERM) and FERMD (7.5% FERM). Each treatment group consisted of 6 replicates with 10 IICC in each. At week 8, one chick from each replicate was randomly taken and slaughtered. After being de-feathered and eviscerated, samples from breast and thigh meats were obtained. Results showed that the increased levels of FERM was followed by the increased (P<0.05) pH values, moisture and crude protein content of breast meats of the IICC. Dietary incorporation of FERM especially at the level of 2.5% increased (P<0.05) the content of fat in the breast meat of IICC, while further increased levels of FERM did not alter (P>0.05) the fat content of the IICC breast meat. Dietary treatment did not have any effect (P>0.05) on the lightness (L*) values of breast meat of the IICC. The redness (a*) values were higher (P<0.05) in FERMD breast meat than other. FERM diet resulted in lower (P<0.05) yellowness (b*) values in the IICC breast meat. The pH values and moisture content of thigh meat increased (P<0.05) with the increased level of FERM. The WHC decreased (P<0.05) with the elevated levels of FERM in the diets. There was an increase (P<0.05) in crude protein concentration in FERMA as compared to the other meats. Crude fat and ash concentrations in thigh meat were affected (P<0.05) by the treatments. Dietary treatments had no impact (P>0.05) on L* values of thigh meats. Feeding FERM at 7.5% from diets increased (P<0.05) and decreased (P<0.05) the redness and yellowness of meats. In conclusion, dietary inclusion of FERM especially at the level of 7.5% from diets improved the physical and chemical characteristics of the IICC meats.
