Irradiationí and its Potential to Food Preservation

Authors: Mohammad Reza Yousefi, Ayat Mohammad Razdari
(2 downloads)
Abstract

In spite of the technologies developed during the last decade, the level of food loss is still high and is reported in many countries. According to the United Nations, more than 30 per cent of the mortality rate world-wide is caused by alimentary diseases. The desire of most countries to make food safer for consumption requires better food preservation and production techniques. In this regard, irradiation is an interesting alternative to be considered Food irradiation is a process exposing food to ionizing radiations such as gamma rays emitted from the radioisotopes 60Co and 137Cs, high energy electrons and Xrays produced by machine sources. Some agricultural products are important commodities in international trade. The trade of these products is often seriously hampered by infestation of several species of insects and mites. The presence of parasites, some microorganisms, yeast and moulds are also the source of problems, sometimes directly or indirectly through toxin formation in the food products. Irradiation alone or combined with others processes can contribute to ensuring food safety to healthy and compromised consumers, satisfying quarantine requirements and controlling severe losses during transportation and commercialization. Depending on the absorbed radiation dose, various effects can be achieved resulting in reduced storage losses, extended shelf life and/or improved microbiological and parasitological safety of foods. However, hindering factors in the way of commercial implementation of the food irradiation process are politics and consumer advocacy. This paper reviews the application of irradiation for preserving some fruit and vegetables.

Abstract

Drought is still limited in most crops is produced. Morphological and physiological knowledge to improve drought resistance under drought conditions created problems important is the fact each of these genetic relationships and processes associated with the exact amount of important plant and grain yield is unknown. The other hand, heritability of grain yield under water is reduced. Improve the performance of drought tolerant cultivars based on morphological and physiological components of plant modification as an important solution is proposed. One of the key predictions of climate change is that, in some regions, droughts are likely to increase in frequency and severity. This will have significant implications for the long-term viability of plant populations, especially where water availability plays a key role in delineating species ranges. However, while drought and overall aridity are known to be strong determinants of plant species distributions at the landscape level, much less is known about the ways in which plant populations respond to changes in drought regime, or the long-term impacts that extreme droughts have on plant community composition, structure, and function. While it is known that drought can cause significant re-structuring of plant communities, relatively few studies have quantified the environmental and biological factors that promote plant survivorship under acute moisture stress, especially in topoedaphically heterogeneous landscapes. The capacity for evolution to rescue plant populations faced with increasingly severe drought from extinction is also poorly understood. This places severe restrictions on our ability to predict the impacts of climate change on plant populations in many environments worldwide. In this paper a review Effects of climate change and Drought-stress on plant physiology.

Abstract

Mites of family Erythraeidae are parasites in their larval stage and predators in their post-larval stages on a variety of arthropods, among which are important pest species. During 2011-2013, in a faunistic survey of mites associated with beetles of the family Chrysomelidae in Oil and Gas company of Gachsaran region, Iran. Specimens were preserved in AG (alcohol 75%, glyserin 5%), cleared in lactophenol solution and mounted by Hoyerís medium. Mite of the genus Leptus (Acari: Erythraeidae) was removed from larva and adult of Cassida persica Spaeth (Coleoptera: Chrysomelidae). The first time in the world C. persica was observed as a new host of Leptus n. sp. It is concluded that Leptus n. sp. can be considered as a valuable addition to the existing IPM methods for Chrysomelid control. Description of new species is in process.

Abstract

Agriculture is a complex system science and the knowledge of it is consisting of much concepts and relationships. Examinations in connection with site-specific farming have been carried out by our institute since 1998. Precision farming is a way of agricultural production, which takes into account the in-field variability, a technology where the application-seeding, nutrient replacement, spraying, etc. has taken place to act on the local circumstances of a given field. The geographic information system (GIS) created by computing background makes possible to generate complex view about our fields and to make valid agro technological decisions. With the advent of the satellite-based Global Positioning System, farmers gained the potential to take account of spatial variability. Our goal was to compare two systems for marking out further research tasks, because in some cases there have been misunderstandings among the researchers, and the information provided by given companies seems to be complicated for potential users. This article provides an overview of worldwide development and current status of precision agriculture technologies and Application of GIS and GPS in Precision agriculture.

Abstract

Objective: Fungal agents cause disease in virtually any susceptible hosts. In the poultry production and medicine, pathogens were eliminated from a line of a breeder by injection of antifungals into hatching eggs. There is little information available describing the safety of the antifungal drugs on the birds embryonated eggs. The objective of this study was to investigate the efficiency of the injection of copper sulfate solution on the chicken embryonated egg. Methods: Fertile chicken eggs were distributed into 3 groups and set in the incubator. On 4th day post incubation, two groups were injected with the copper sulfate solution, 5 and 10 mg per Kg egg-weight, dissolved in 0.5 ml phosphate buffered saline. The rest group was used as sham control (0.5 ml phosphate buffered saline solution). Results: Macroscopic evaluation on 18th day post incubation showed that embryos were normal in all treatment groups. Microscopically, no lesions were also diagnosed in the brain, heart, muscle, liver, kidney and lung of the embryos. Based on macroscopic and microscopic findings, it is concluded that copper sulfate at abovementioned concentration is not toxic for the chicken embryo at the stage of development. So, copper sulfate egg-injection can be used to eliminate fungal agents without any adverse effect.

Abstract

Objective: In this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electroosmotic flow. Methods: The base liquid is an electrolyte which flows in a twodimensional micro-channel having electrically charged walls. Lorentz electric force, which is used as stimulating flow factor, is created by applying an external electric field on the electric double layer (EDL) aroused by adjacency of electrolyte and charged wall. Results: To ensure the convergence of the results obtained from the computer program, equations are solved iteratively until the residual amount after solving each equation is less than machine error and independence of results from the number and location of network nodes is verified for an experimental flow. To increase the mixing efficiency, some square and triangle shaped obstacles are embedded on the micro channel wall. Herein, the fundamental principles for passive mixing as well as the effect of frequency and height of the barriers on mixing efficiency are studied. The obtained results from numerical solving of electro-osmotic flow in micro-channel are compared with the theoretical results and a very good agreement is observed.

Abstract

Objective: In order to study the effect of different concentrations of IBA hormone on rooting of olive cuttings in spring and winter of 2012-2013 in a greenhouse in Jiroft, Iran. Methods: a split-plot experiment was conducted on the basis of a Randomized Complete Block Design in which hardwood cuttings of one-year-old olive plants cv. Manzanilla with the diameter of 0.7-1 cm were used. The main plot was devoted to cutting seasons at two levels of spring (late-May) and winter (late-January) and the sub-plot was devoted to IBA (indulebutyric acid) hormone treatment at five levels of 0, 1000, 2000, 3000 and 4000 ppm. Results: It was found that 3000 ppm IBA increased the number of roots, the percentage of rooted cuttings, branch length, and root:shoot fresh weight. In traits such as root length and root dry weight, the highest effect was observed under the treatment with 4000 ppm IBA. But, control treatment had the lowest effect on the traits of rooting in olive cuttings. Cuttings planted in spring showed the highest effect on their evaluated traits (by 10-15%) with a significant difference with those planted in winter. The interaction between hormone and planting time was significant only for root fresh weight.

Abstract

Objective: Wheat is the most important crop in Iran. Self sufficiency in wheat production is one of the economic and food safety policies in the country. In spite of the efforts which have been made in this area, the mean of wheat yield in Iran is less than its world average. Methods: In order to identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. Results: Significant differences were observed among the lines for all of studied traits, except the spike weight, flag leaf area and the straw yield. Higher genetic diversity was observed among the inbred lines with respect to the kernel per spike, the number of spikes, the biomass and the straw yield. The Peduncle weight, second internode weight, number of kernels per spike per spike, number of the spikes and 1000 kernel weight traits showed a high degree of heritability. The highest genetic gain was estimated for the peduncle weight, the second internode weight and number of kernel per spike. Correlation, stepwise regression and path analyses revealed the number of kernels per spike and the number of spikes in plot had highest direct effects on grain yield. The analyses were carried out using WARD algorithm and standardized data. Cluster analysis based on all traits assigned the lines into groups.

Abstract

Objective: In recent years, farmers have shown great interest to using native drill planter rather than complex planters to grow vegetables. Methods: In this study, we tested a native planter Independent variables were the two types of substrate surface (asphalt and plowed field), three ground speed (3, 5 and 7 kph) and four types of seeds (tomatoes, onions, radishes and lettuce). Dependent variables were the seedís lateral dispersion coefficient compared to the straight line, seed shedding rate per unit area. effect Percentage of metering device on seed viability, and breakage percentage of seeds after crossing the metering device. Results: The results showed that, the rate of seed shedding per hectare declines in all seeds along with increasing ground speed. However the lateral dispersion coefficient of the straight line planting has increasing trend along with increasing ground speed and the both parameters are lower in asphaltís substrate surface than the cultivated ground. breakage percentage of seeds and effect Percentage of metering device on the viability of seeds after passing through the planter are also very low. It assume that use of the planter in front of method of hand cultivation reduce some costs such as costs of seedís purchase.
