食品安全监管的法学价值思考

近年来,食品安全问题屡屡发生,不断引起人们和政府的重视。对于食品安全监管的法学理论依据,从已有的文献来看很少涉及,特别是从价值法学的角度更是鲜见,这不能不说是一个遗憾和缺失。在本文中笔者站在法学的立场透视食品安全监管的立足理论根基,以期给食品安全监管模式的构建以及具体制度建设提供更加充分的理论指导。     

基于旅游需求的饮食文化资源开发——以淮安为例

随着旅游者需求的不断变化,作为旅游资源的饮食文化必须基于旅游者需求基础上进行开发,才能获得旅游者的认可。淮安是著名的淮扬菜发源地之一,饮食文化历史悠久,内涵丰富。在现今旅游者需求日益变化的市场条件下,淮安饮食文化旅游产品的开发只有以终端市场的需求为核心,运用主题化、个性化、多样化、生态化开发策略,才能重振淮扬菜雄风。

论餐饮食品安全管理

把握和控制食品安全问题,必须从食品安全源的角度对食品安全进行科学、合理的分类,明确餐饮食品生产及消费过程中各关键环节安全控制的标准,构建餐饮食品危害分析与关键控制点体系,完善餐饮食品安全管理制度,实现餐饮食品安全的科学管理。     

Coupling System for Food Wastes Anaerobic Digestion and Polyhydroxyalkanoates Production with Ralstonia eutropha

A new technology was developed to couple the anaerobic digestion of food wastes with production of polyhydroxyalkanoates (PHAs). Acetic, propionic, butyric and lactic acids were produced during food wastes anaerobic digestion and their concentrations reached 5.5, 1.8, 27.4 and 32.7 g/L, respectively under appropriate digestion conditions. The fermentative acids were transferred through a dialysis membrane to an air-lift reactor for PHA synthesis by Ralstonia eutropha. Dry cell concentration and PHA content reached 22.7 g/L and 72.6%, respectively. The obtained PHA was a copolymer of b-hydroxybutyrate (HB) and b-hydroxyvalerate (HV) with 2.8% (mole ratio) of HV units in polymer.     

Ozone: An Advanced Oxidation Technology for Starch Modification

ABSTRACT

Ozone processing is one of the encouraging non-thermal and bio-friendly techniques in the food processing sector. The applicability of ozone technology in food industry is increasing due to its antimicrobial action and modification of functional properties of the foods. The structural modifications of starches have major applications in the food and bakery industry for producing products with increased shelf life, improved texture, and retention of moisture content. The positive response of ozonation in carboxyl and carbonyl group alters the viscosity of starch molecules. Rheological characteristics like low viscosity even at an increased concentration, desirable binding properties, and film-forming ability have increased its use in the food processing industry. The influence of ozonation in the physicochemical properties is mainly retrogradation and cross-linking of amylose and amylopectin molecules and enzymatic modifications. Ozonation cause change in crystallinity, viscosity, expansion ratio, and gelatinization temperatures. Finally, ozonation induces many possible changes in native starches for the effective utilization in the processing sectors. In this review, starch modifications utilizing ozone and various research achievements and scientific reports focusing on the effect of ozonation in terms of physical, chemical, and thermal properties of native starches and on the possible modifications have been summarized and discussed. In conclusion, ozone is a green technology that can be effectively used as an alternative oxidation technique for starch modification.

Consumer‐diet discrimination of δ13C and δ15N: Source‐ and feeding‐oriented patterns based on gut content analysis in a large subtropical river of China

Understanding the trophic discrimination (?¹³C and ?¹⁵N) between consumers and diets in fluvial systems remains difficult because of the variable food sources and complex predator–prey interactions from headwaters to the estuaries. Here, stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotopes in fish and invertebrates from a large subtropical river in southern China were determined to explore trophic discrimination in conjunction with a gut content analysis. The ?¹³C values showed significant differences (p < .05) among functional feeding groups, with fish, shrimp, and insect scrapers presenting higher ?¹³C values (1.20 ± 0.23‰ to 1.51 ± 0.31‰) than other groups. The ?¹⁵N values varied significantly between invertebrates (0.64 ± 0.17‰ of insect collector‐gatherers to 1.63 ± 0.36‰ of shrimp predators) and fish (1.98 ± 0.19‰ of detritivores to 2.71 ± 0.43‰ of crustaceavores) and exhibited an increasing tendency from primary to secondary consumers. A linear regression analysis revealed that the longitudinal changes in ?¹³C and ?¹⁵N were closely associated with the δ¹³C of periphyton, the δ¹⁵N of particulate organic matter (POM) in water, and the relative contribution (%) of periphyton and organic detritus to the diet composition of consumers. These results indicated that discrimination factors might not only be influenced by the isotope signatures of basal food sources but also downstream shifts in dominant food items utilized by consumers. In particular, trophic discrimination between periphyton– and detritus–based food chains, such as “epilithic diatoms–shrimp scrapers–crustaceavorous fish” and “POM–bivalves–molluscivorous fish,” displayed regionally specific patterns. When back‐calculating to the diet assimilation and trophic position in subtropical streams and rivers, we suggest using the basin‐scale ?¹³C value of 0.96 ± 0.26‰ for all consumers and ?¹⁵N values of 1.07 ± 0.32‰ for invertebrates and 2.38 ± 0.37‰ for fish.     

论食品安全领域权利救济的预防性行政诉讼

从《食品安全法》中规定的或推定的权利救济途径来看,事后救济明显存在不足,预防性行政诉讼尤显必要。预防性行政诉讼的适用前提是明确其与尊重行政的首次性判断权、风险预防原则以及成熟原则的矛盾与联系问题。在食品安全领域,行政相对人在以下两种情况应该有权提起预防性行政诉讼：一是食品安全主管机关拟作出的责令停产停业、吊销许可证或执照、行政处罚决定;二是行政机关公布有毒有害食品信息可能对行政相对人造成不可弥补的损害。
