  • Carcass vascular rinsing and chilling involves infusing a chilled isotonic solution (98.5% water and a blend of mono- and di-saccharides and phosphates) into the vasculature immediately upon exsanguination. Primary purposes of carcass vascular rinsing are to (1) effectively remove residual blood from the carcass; (2) lower internal muscle temperature rapidly; and (3) optimize pH decline by effective delivery of glycolytic substrates in the rinse solution. Previous studies have revealed that the beef carcass vascular rinsing early postmortem positively affects meat quality, product shelflife, and food safety. Thus, the objective of this review is to provide a more comprehensive understanding of the physical and biochemical mechanisms associated with beef carcass vascular rinsing, focusing on the relationship between quality attributes (CIE L*, a*, b*; chemical states of myoglobin; oxygen consumption and sarcomere length) and muscle metabolic response to various substrate solutions (Rinse & Chill®, fructose, sodium phosphate, and dipotassium phosphate) that stimulate or inhibit the rate of glycolysis early postmortem. In addition, this review discusses the absence of metabolite residues (phosphorus, sodium, and glucose) related to the application of the chilled isotonic solution. This review primarily focuses on beef and as such extending the understanding of the mechanisms and meat quality effects discussed to other species associated with vascular rinsing, in particular pork, may be limited.

  • PEGylation, the attachment of polyethylene glycol (PEG) to proteins, is currently main technology for improving efficacy of protein drugs. This technology can prolong the plasma half-life, augment the in vivo stability, and diminish the immunogenicity of therapeutic proteins. Therefore, PEGylated proteins have the enhanced therapeutic efficacy and the reduced undesirable effects versus their native therapeutics. Since the first PEGylated protein product appeared on the market in the early 1990s, currently ten PEGylated protein products have been launched. These marketed drug products have proved the applicability and safety of the PEGylation technology. This review presents overview of PEGylation technology and addresses characteristics of PEGylation methods applied for the development of several protein drugs.

  • Polystyrene is frequently used for food packaging because of its eaxy processing rigidity , and low cost. Styrene, which is present in detectable amouts in the polymer, is usually considered to be the substance responsible for the possible tainting of a polystyrene-packed food by migration. The contamination of foods and beverages by trace amounts of materials which have migrated from plastics use din packaging is a concern both on the grounds of adversely affecting product quality and of food safety. These lead to increasing attention to the potentional hazards of a large variety of plastic materials and foods. In this paper we reviewed the history of Styrene and various analytical methods of sample preparation and detection to assess the extent to which styrene is present in food-grade polystrene materials and to what extent it leaked into foods and food stimulants.

  • This study aims to examine the relationship between certain dimensions of Corporate Social Responsibility (CSR) with market performance, measured by Tobin's Q, on companies within various industries in Indonesia. This study disaggregates CSR into 7 dimensions: environment, energy, occupational safety and health, employee, product, community, and general. Samples consisted of 385 companies listed on the Indonesia Stock Exchange (IDX) during 2007-2014. OLS analysis shows that CSR contributes greatly to the formation of market performance of consumer goods, agriculture, and miscellaneous industries. The dimensions of CSR contribute differently to the formation of Q ratios in different industries. We also found that there are differences in the speed of effect of several dimensions of CSR on the formation of market performance; some CSR dimensions give immediate effect while others are lagged.

  • Before the advent of pasteurization and other microbiological controls in the dairy industry, milk product-borne diseases such as scarlet fever, typhoid fever, septic sore throat, and tuberculosis were globally widespread. Pasteurization was invented by Louis Pasteur, and it has been considered as one of the most effective ways to control milk product-borne diseases since the 20th century. Nevertheless, till date, various types of cheese in the EU, the USA, and other countries are made from unpasteurized milk as artisan cheese, following the specific food regulations of each nation. Furthermore, after the effectiveness of the Free Trade Agreement (FTA) negotiations between Korea and many nations, the import of various types of cheese made in different conditions and influenced by acidity, preservatives, temperature, competing flora, water activity, and salt concentration increased yearly. Hence, the objective of this review was to describe (1) the 60-day aging rule of cheese, (2) characteristics of the outbreaks linked to cheese manufactured from unpasteurized milk since 1998 to 2011 in USA, and (3) serious health risks from unpasteurized milk, to ensure food protection and safety and to use this basic information for risk assessment.

  • Given a bill of materials (BOM) tree T labeled by the breadth first search (BFS) order from node 0 to node n and a general network ${\Im}=(V,A)$, where V={1,2,...,m} is the set of production facilities and A is the set of arcs representing transportation links between any of two facilities, we assume that each node of T stands for not only a component. but also a production stage which is a possible stocking point and operates under a periodic review base-stock policy, We also assume that the random demand which can be achieved by a suitable service level only occurs at the root node 0 of T and has a normal distribution $N({\mu},{\sigma}^2)$. Then our integrated model of facility location problems and safety stock optimization problem (FLP&SSOP) is to identify both the facility locations at which partitioned subtrees of T are produced and the optimal assignment of safety stocks so that the sum of production cost, inventory holding cost, and transportation cost is minimized while meeting the pre-specified service level for the final product. In this paper, we first formulate (FLP&SSOP) as a nonlinear integer programming model and show that it can be reformulated as a 0-1 linear integer programming model with an exponential number of decision variables. We then show that the linear programming relaxation of the reformulated model has an integrality property which guarantees that it can be optimally solved by a column generation method.

Comparative Assessment of Good Agricultural Practices Standards in Agricultural Product Quality Control Act with respect to Produce Safety Rule in Food Safety Modernization Act (식품안전현대화법의 농산물안전규칙과 농산물품질관리법의 농산물우수관리기준 비교평가)

  • The US government has enacted the Food Safety Modernization Act (FSMA) in 2011, which is being phased in and planned. The final Rules of Produce Safety focus on biological hazards related to agricultural production, harvesting, packaging and storage, which are being phased in since 2017 depending on farm scale. As a result of comparison with the Korean-GAP (Good Agricultural Practices) standards, it is difficult to compare the two standards to be compared with each other by 1:1. However, many of the Korean-GAP standards are similar to FSMA Produce Safety rules. However, the Korean-GAP standards can be judged differently according to the evaluator as a comprehensive standard, so the details of the standards need to be reinforced. In terms of the provisions, the Korean-GAP standards are the most appropriate for the safety of workers (FSMA Subpart D), followed by livestock and wild animals (FSMA Subpart I), buildings, equipment and tools (FSMA Subpart L) and harvesting activities (FSMA Sub-part K). However, there are some weaknesses in the field of agricultural water management (FSMA Subpart E) and farm manager's qualifications and training (FSMA Subpart C), and the response to the biological soil amendments of animal origin and human waste (FSMA Subpart F) is weak. The FSMA regulation is not a certification standard, but it is expected that the marbling effect, which is the standard laid down by the United States leading the world food safety standards, is expected to be considerable. Therefore, we hope that the review of the Korean-GAP standards will help improve the quality of agricultural products and expand our exports, since the standard for responding to microbiological safety emphasized in the FSMA regulations is the Korean-GAP standard.
