Qualidade higiênica do queijo de manteiga artesanal comercializado na feira livre em Bom Jesus-PI / Hygienic quality of cheese artisanal butter sold in the open market at Bom Jesus-PI

This study aimed to evaluate the microbiological quality of butter cheese sold in the open market of Bom Jesus - PI, by counting of mesophilic aerobic (MA) bacteria and enumeration of total and thermophilic coliforms. Twenty-three samples were purchased and sent to the microbiology laboratory of the Food / Campus oh the Bom Jesus - UFPI. For MA count inoculated aliquots of decimal dilutions Plate Count Agar for incubation at 36°C/48h. The colimetric assays followed the technique of multiple tubes VBBL broth and broth Escherichia coli, and incubated at 35°C - 44,5°/48h, respectively. MA counts ranged from 1.0 x102 to 1.3 x 105 CFU/g. Only one sample (4.35%) was positive for total coliforms. The butter cheese sold in the open market of Bom Jesus-PI is manipulated under deficient hygienic conditions. Corrective measures should be taken to reduce the contamination of the product.

Dehydration and chemical composition of Leucena (Leucena leucocephala) and Gliricidia (Gliricidia sepium) / Desidratação e composição química do feno de Leucena ("Leucena leucocephala") e Gliricidia ("Gliricidia sepium")

The objective was to evaluate the chemical composition and time to reach the point of hay of Leucena (Leucena leucocephala) and Gliricidia (Gliricidia sepium). Samples were collected in time 0, 2, 4, 6, 8, 10, 12, 14, and 16 hours of drying to obtain dehydration curve for each species of forage. The design was completely randomized with nine treatments (9 times of dehydration x three replicates). Data for morphological characteristics of the species were subjected to statistical analysis of variance, and means were compared by Tukey test at 1% probability. For dehydration curve as a function of time, the data were subjected to regression analysis. The leaf:stem ratio was higher for Gliricidia in time and 16 hours of dehydration (P  0.05). The rates dehydration of Composed samples of pod, stem and leaf of Gliricidia and Leucena showed a linear increase (P 0.05) and the Leucena dehydration was most efficient. The dry matter content of Gliricidia and Leucena showed, respectively, 91.24% and 91.32% content, while the crude protein content was 18.64% and 17.7%. The fiber content neutral detergent corrected for ash and protein content was the 49.86% and 49.07, the neutral detergent insoluble protein content was 1.01% and 1.77%. The time to reach the point of Leucena and Gliricidia hay was 16 hours. The nutritional composition of hay Leucena and Gliricidia were satisfactory(AU)

Objetivou-se avaliar a composição química e tempo para atingir o ponto de fenação da Leucena (Leucena leucocephala) e Gliricidia (Gliricidia sepium). Foram coletadas amostras nos tempos 0, 2, 4, 6, 8,10, 12, 14, e 16 horas de secagem para obtenção da curva de desidratação para cada espécie de forragem. O delineamento adotado foi o inteiramente casualizado com nove tratamentos (9 tempos de desidratação x três repetições). Os dados referentes às características morfológicas da espécie foram submetidos à análise estatística de variância e as médias foram comparadas pelo teste de Tukey a 1% de probabilidade. Para a curva de desidratação em função do tempo, os dados foram submetidos à análise de regressão. A relação folha:caule foi maior para a Gliricidia no tempo 16 horas de desidratação (P 0,05). As taxas de desidratação da amostra composta, vagem, colmo e folha composta da Gliricidia e Leucena apresentaram efeito linear crescente (P 0,05) com a Leucena mais eficiente na desidratação. Os teores de matéria seca da Gliricidia e Leucena foram, respectivamente, de 91,24% e 91,32%, enquanto os teores de proteína bruta foram de 18,64% e 17,7%. Os teores de fibra em detergente neutro corrigida para cinzas e proteína foram de 49,86% e 49,07%, e os teores de proteína insolúvel em detergente neutro foram de 1,01% e 1,77%.
