Food Irradiation Regulations in China and other Asian countries 

The presentation will introduce regulations and national standards related to food irradiation in China. There are about 200 commercial irradiation facilities, and 0.6 million ton of irradiated food per year, so the legal issues for ensuring the application of food irradiation technology in China will also be analyzed. The regulations on both sanitary and phytosanitary uses in Asian countries will be summarized.

Abstract

55 years applying Nuclear Techniques to Agricultural sciences in Brazil

The Center for Nuclear Energy in Agriculture (CENA) is a specialized Institute of the University of São Paulo (USP) dedicated to generate and disseminate knowledge related to agriculture and environment, using nuclear and related techniques. CENA is located at the municipality of Piracicaba, São Paulo state, Brazil, and it was established in 1966 after an initiative made by a group of professors from USP that started using nuclear techniques in studies with soil nutrition, tractor engines and other areas. In 1967, IAEA donated a 60Co irradiator and its research areas expanded to include food irradiation, mutation breeding, animal nutrition, the Sterile Insect Technique, among others. Today, CENA has 3 scientific divisions with 21 Laboratories, 32 professors and 115 technicians. There are two postgraduation courses with ca. 200 students currently. Some of CENA’s remarks include 11,454 scientific publications since 1970, more than 900 postgraduates, 11 commercial cultivars obtained by mutation breeding, and provision of sterile insects and irradiation services to agricultural products for domestic and export markets.

Monique Lacroix

Monique Lacroix is a Professor and Director of the Research Laboratories in Sciences, Applied to Food and of the Canadian Irradiation Centre, at INRS, Armand-Frappier Health & Biotechnology Centre. She is Fellow of the International Academy of Food Science and Technology. 

Prof. Lacroix is a distinguished member of numerous national and international scientific societies and expert committees such as the World Health Organization (WHO) and of the International Atomic Energy Agency (IAEA).  Her research program focuses on using irradiation to assure food security and sustainability, to reduce food loss and waste, and food packaging waste. Her works respond to consumer demands to replace chemical additives with natural antimicrobial extracts while preserving the nutritional value, assuring the safety and long shelf life of foods. Her contributions include the integration of structure, chemistry and function of natural extracts and food composition for the development of efficient antimicrobial edible coatings; the incorporation of nanotechnology for the development of new method of encapsulation to improve the efficiency and to assure a controlled release of the immobilized natural extracts; the advancement of irradiation and non-thermal technologies in combination with natural extracts for the development of unique methods of preserving food; the combined use of green chemistry and physical treatment and valorisation of industrial sub-products for the development of nano – biomaterials and insoluble food packaging and active films.

Abstract

Active natural polymers and new combined treatments with irradiation

Packaging or edible coating based on natural polymers containing plant-extract play an important role in food industry. When encapsulation under nanoscale, their bioactivity can be enhanced, thereby enabling the reduction of the doses required to ensure the biological activity. Combining irradiation with active natural polymers can increase microbial radiosensitivity and reduce the dose of individual treatment while maintaining the quality and safety of the food product.Radiation treatment can also serve as a tool for crosslinking, surface grafting and for reactive compatibilization of natural polymers. In this presentation I will present a summary of the different opportunities that irradiation can bring for the development of active polymers or new combined treatments to assure food safety.

Anuradha Prakash

Anuradha Prakash is Professor and Director of the Food Science Program at Chapman University.  She serves as Science Advisor to the FDA office (Pacific Southwest Food and Feed lab) and is a Fellow of the Food Systems Leadership Institute.

Anuradha teaches Food Processing and Food Product Development.  Her research program focuses on using irradiation to enhance the safety and shelf-life of fresh-cut fruits and vegetables and ready-to-eat meals.  At present, she is evaluating the effect of irradiation on the quality of fruit treated by irradiation for insect disinfestation with the goal of eliminating global trade barriers by reducing the threat posed by invasive pests.  

ABSTRACT

 “Effect of phytosanitary irradiation of fresh fruit and vegetable quality”

The use of irradiation to mitigate insect pests on fruit and vegetables continues to increase worldwide.  At the low doses, (<= 400 Gy), used for phytosanitary purposes, the effect on quality can be negligible.  Still, since the fresh fruit and vegetables continue to be metabolically active, the impact is highly dependent upon the type of fruit being treated, whether it is climacteric or not, how it is transported and how long it is stored following treatment.  In this presentation I will provide an overview of these impacts, and the latest research on produce quality.

Matthew Murdoch

Dr Matthew Murdoch is a Physicist at Buhler AG providing dosimetry and radiation expertise for the LEEB product line. He has 10 years of experience in radiation measurement and Monte Carlo simulations in both academia and industry. Since joining Buhler he has created simulations for both product dosimetry and radiation safety as well as designing dosimetry trials for process control.

Abstract

Monte Carlo simulations for low energy electron beam

Monte Carlo radiation simulations are commonly used in high energy electron beam processing to estimate doses where they cannot be reliably measured. The use of these simulations range from product dosimetry to radiation safety. While high-energy electrons have ranges of order a few centimetres, low-energy electrons have ranges of a few hundred microns in water. At this short length scale additional details in the simulation model become important and must be balanced against hardware and software limitations. This talk will discuss some of these details and limitations. Results from low-energy electron beam simulations will be presented.
