Authentizität und Sicherheit von Möhrenproben im Rahmen des CORE-Organic QACCP Projektes

Consumer demand for healthy, safe and high quality food is increasing. Against this background, the demand for organically grown food has been growing rapidly. Organic farming contains the whole food chain from field to fork. An analyse system to optimise the process needs to be established (QualityAnalysisCriticalControlPoint). The aim of the transnational CORE-Organic QACCP project is a chain analysis which addresses the link between farm and fork and backwards from fork to farm. The objective is to improve product related quality management in farming and processing. The results presented here are dealing with food authenticity on farm level through biocrystallization measurements and food safety through pesticide residue and nitrate determination

Quality and Safety Aspects of Infant Nutrition

Quality and safety aspects of infant nutrition are of key importance for child health, but oftentimes they do not get much attention by health care professionals whose interest tends to focus on functional benefits of early nutrition. Unbalanced diets and harmful food components induce particularly high risks for untoward effects in infants because of their rapid growth, high nutrient needs, and their typical dependence on only one or few foods during the first months of life. The concepts, standards and practices that relate to infant food quality and safety were discussed at a scientific workshop organized by the Child Health Foundation and the Early Nutrition Academy jointly with the European Society for Paediatric Gastroenterology, Hepatology and Nutrition, and a summary is provided here. The participants reviewed past and current issues on quality and safety, the role of different stakeholders, and recommendations to avert future issues. It was concluded that a high level of quality and safety is currently achieved, but this is no reason for complacency. The food industry carries the primary responsibility for the safety and suitability of their products, including the quality of composition, raw materials and production processes. Introduction of new or modified products should be preceded by a thorough science based review of suitability and safety by an independent authority. Food safety events should be managed on an international basis. Global collaboration of food producers, food-safety authorities, paediatricians and scientists is needed to efficiently exchange information and to best protect public health. Copyright (C) 2012 S.

Effect of Dietary Advanced Glycation End Products on Mouse Liver

The exact pathophysiology of non-alcoholic steatohepatitis (NASH) is not known. Previous studies suggest that dietary advanced glycation end products (AGEs) can cause oxidative stress in liver. We aim to study the effects of dietary AGEs on liver health and their possible role in the pathogenesis of NASH. METHODS: Two groups of mice were fed the same diet except the AGE content varied. One group was fed a high AGE diet and the second group was fed a regular AGE diet. Liver histology, alanine aminotransferase, aspartate aminotransferase, fasting glucose, fasting insulin, insulin resistance and glucose tolerance were assessed. RESULTS: Histology revealed that neutrophil infiltration occurred in the livers of the high AGE group at week 26; steatosis did not accompany liver inflammation. At week 39 livers from both groups exhibited macro- or micro-steatosis, yet no inflammation was detected. Higher insulin levels were detected in the regular AGE group at week 26 (P = 0.034), compared to the high AGE group. At week 39, the regular AGE group showed higher levels of alanine aminotransferase (P<0.01) and aspartate aminotransferase (P = 0.02) than those of the high AGE group. CONCLUSIONS: We demonstrate that a high AGE diet can cause liver inflammation in the absence of steatosis. Our results show that dietary AGEs could play a role in initiating liver inflammation contributing to the disease progression of NASH. Our observation that the inflammation caused by high AGE alone did not persist suggests interesting future directions to investigate how AGEs contribute to pro-oxidative and anti-oxidative pathways in the liver

Fluorescence-based concept of Naturalness applied to organic processed fruit and vegetables

Background: According to the European regulation N°834/2007, processing of organic food should preserve the essential qualities of the fresh raw material. Thus, assessment of processed food quality should include verification of the absence of additives and contaminants and preservation of the sensorial, nutritional and health values of the raw material. In this paper, a quantifiable concept of naturalness measuring global quality loss due to processing and storage of raw organic material is proposed. This indicator is based on Front face fluorescence; a global and sensitive technique able to assess in real time and non-destructively these various dimensions of the food quality. Results: A strong relationship between the naturalness levels estimated from front face fluorescence measurements and conventional chemical quality markers was found in several applications on different food matrices. The results also show that the naturalness indicator, which provides a global appraisal of the product quality, can also be used for process optimization through the evaluation of the impact of preprocessing of raw material, thermal treatments, packaging, storage, etc. Conclusion: Front face fluorescence based measurement of quality loss during food processing and storage is a promising innovative approach which allows real time non-destructive assessment of the level of naturalness of an organic food product
