Mechanically Separated Meat

Mechanically separated meat (MSM) is obtained from bones or fragments with naturally adherent soft tissue by mechanical separation of soft tissue residues from bones remaining after cutting and punching poultry, pork and beef carcasses. Mechanically separated meat is a raw material commonly used in processing in Poland and other countries. The dominant species in the production of mechanically separated meat in Europe is poultry, mainly because of the increase in the consumption of boneless meat and its products. Mechanically separated meat is characterized by poorer technological and physicochemical properties and lower durability compared to poultry meat cut by hand. The high microbiological contamination of raw material limits its further use. The microbiological quality of mechanically separated meat has a significant impact on the microbiological stability and health safety of products manufactured from it. In industrial practice, mechanically separated meat is preserved by freezing or curing. In view of problems with the microbiological quality of mechanically separated meat, it seems advisable to search for new methods of preserving MSM and to improve the existing ones

Rainwater Quality

The large temporal and spatial variability of rainwater quality, as well as the relatively small number of tests, makes the preliminary assessment of its economic exploitation difficult. Determining the relationship between the conditions and location of rainwater collection and rainwater quality would help indicate the range of options for rainwater use, as well as the parameters that require improvement. The aim of the presented article is to establish the physical, chemical, and microbiological parameters of different rainwater sources and, from the results obtained, determine the possibilities for its safe use in households. The research was carried out for two years. Samples of rainfall were collected from spring to fall from the following roofing materials: Concrete roof tiles, ceramic roof tiles, galvanized steel sheet, and epoxy-coated terrace. The physical, chemical, and microbiological quality were assessed on the basis of the pH, turbidity, electrical conductivity, the concentration of biogenic compounds, the concentration of chosen elements, the number of Escherichia coli, and the number of fecal streptococci. Significant bacterial contamination, decreased pH, and increased turbidity were identified in the water, depending on the parameters of the roofing washed by the rainfall and the intensity and frequency of precipitation.

Guideline Values

Background: Global statistics show that over 1.2 billion people do not have access to potable water and 70% of Nigerians lack access to potable water. Non-availability and/or lack of access to potable water predispose people to preventable life-threatening conditions. This study assessed the physical, chemical, and microbiological quality of sachet and bottled water to generate evidence for planning, policy, and intervention.Methods: The study was a cross-sectional analytic study of the quality of packaged (sachet and bottled) drinking water obtained from consumer households. The potability status of the water samples was assessed by means of qualitative assessments and quantitative laboratory tests. The results were compared to guideline values stipulated by the Nigerian Industrial Standard for Potable Water, NIS 306:2008. Data were analyzed using descriptive and inferential statistics. A p-value of <0.05 was considered statistically significant. The study period was from April 2016 to June 2016.Results: Of the 35.0 bottled water samples, 18.0 (51.4%), 21.0 (60.0%) and 17.0 (48.6%) had their production dates, expiry dates and batch numbers. All 65.0 (100.0%) samples appeared colourless to the naked eye and visible particles were present in 3.0 (4.6%) of the total water samples. The lead content of 7.0 (23.3%) sachet and 1.0 (2.9%) bottled sample exceeded the guideline value for lead. The pH of 16.0 (53.3%) sachet samples and 27.0 (77.1%) bottled samples fell below the recommended limits for pH. Escherichia coli was found in 4.0 (13.3%) and 15.0 (42.9%) of sachet and bottled water samples.Conclusions: The study suggested that sachet and bottled water sold in Nnewi have good physical qualities, but poor chemical and microbiological qualities. More of the microbiological contaminant (E. coli) was present in the bottled water than the sachet water.

Jenang, or what is often called dodol, slab, or gelamai, includes dense, chewy, half-processed products. Jenang, which was innovated from chayote, has a relatively short shelf life, which is only able to survive 3-5 days at room temperature (27ºC). Therefore, a good packaging is needed that can extend the shelf life of one of them is edible coating, which is the packaging of edible materials. Edible coating is one of the efforts that can be done to maintain the quality of a food. The purpose of this study was to determine the quality and estimation of chayote with and without edible jenang based on physical, chemical, and microbiological parameters. In this study using the analysis of water content, peroxide numbers, and total microbes and using the edible dip method. From the research it can be seen that the chayote jenang based on physical quality in edible samples can maintain the water content so that the texture remains elastic compared to without edible until the 15th day. Based on the chemical quality in jenang squash with edible, oxidation only occurred after storage on the 22nd day. Microbiological quality in the conjoined pumpkin jenang coated with edible or without edible was overgrown with a total amount of yeast mold ≥300,000 Cfu / g.

<p>O objetivo do presente trabalho foi avaliar a influência de sacos plásticos de Polietileno de Baixa Densidade (PEBD) e embalagens a vácuo sobre a cor, a qualidade físico-química e microbiológica do queijo Minas frescal. Foram avaliados 10 queijos provenientes de 5 produtores artesanais da cidade de Belo Horizonte, adquiridos 2 dias após a fabricação. Os queijos foram divididos em dois grupos, cada qual com 15 unidades (três pedaços de cinco queijos), e acondicionados em geladeira a temperatura de 6 ºC até o momento dos testes. As análises de pH, teor de umidade, teor de gordura, microbiológicas e o estudo da cor foram feitos nos dias 0, 10 e 20, tanto da parte interna, quanto da parte externa do produto. O uso de ferramentas quimiométricas, como o Image Principal Componente Analysis (PCA de imagens), permitiu evidenciar alterações de cor das amostras no período de observação e correlacioná-las com os dois tipos de embalagens utilizados e com os valores obtidos nas análises físico-químicas. Os resultados apontaram que as características das embalagens relacionadas à permeabilidade a gases e vapor d’água propiciaram alterações físico-químicas e microbiológicas nas amostras, resultando em diferentes tonalidades de amarelo perfeitamente evidenciadas pelo PCA, sendo que a embalagem a vácuo se demonstrou mais eficaz na conservação das propriedades avaliadas. A contaminação microbiológica das amostras ressaltou a importância das boas práticas de fabricação (BPF) na qualidade do queijo Minas frescal.</p><p>Abstract</p><p><span lang="EN-US">The purpose of this paper was to evaluate the influence of Low Density Polyethylene plastic bags (LDPE) and vacuum packaging on the color, physicochemical and microbiological quality of Minas fresh cheese. 10 cheeses from 5 artisan producers from the city of Belo Horizonte were acquired two days after fabrication. The cheeses were divided into two groups, each one with 15 units (three pieces of five chesses), and stored in a refrigerator at 6 ° C until the day of analysis. The analysis of pH, humidity content, fat content, microbiological and the study of color were made on days 0, 10 and 20, both in the inner and the outer part of the product. The use of chemometric tools, such as Principal Component Image Analysis (Image PCA), was able to detect the color changes of the samples during the observation period and correlate them with the two types of packaging and the variations on the physical chemical parameters. The results showed that the characteristics of the packages related to gases and water vapor permeability have provided physical, chemical and microbiological changes in the samples, resulting in different shades of yellow, perfectly highlighted by the PCA. Microbiological contamination of the samples stressed the importance of good manufacturing practices (GMP) on the quality of Minas fresh cheese.</span></p>

This work is the result of 3 years of collaborative research between Mississippi State Univ. and New Mexico State Univ. Physical, chemical, and sensory characteristics were studied to assess eating quality of popular New Mexico pecan (Carya illinoinensis) cultivars. The force and energy necessary to break (shear) pecan nuts, and Hunter `a' and hue angle values varied with harvest year and cultivar. All other traits, including sensory evaluation results, varied only with cultivar. `Ideal' was of light color, small size, and not as firm as the others, while `Burkett' was soft and slightly rancid. `Wichita' was the cultivar rated best by panelists, despite its slightly darker color. `Western Schley' and `Salopek' were also acceptable, although not as acceptable as `Wichita'.
