Abstract

Introduction:

In the present study, the effects of gamma irradiation and packaging on storage quality of partially matured peach was studied. The fruit was irradiated in the dose range of 2.5 and 5.0 kGy and was stored in paper and wooden boxes at ambient temperature (25±2 OC).

Methods and Materials:

The samples were evaluated at regular intervals (weekly) for moisture, ash, ascorbic acid, crude carbohydrate, crude protein, crude fibre and crude fat. Maximum increase (0.23%) of ash content was recorded for sample irradiated with 5.0 kGy stored in wooden box during the second week. The decrease in moisture contents, crude protein, fat, fibre and ascorbic acid was observed in all packed and irradiated (5.0 kGy) samples.

Results:

The results clearly indicate the effect of paper packaging and radiation doses on fruit (peach) quality. The shelf life of peach was increased up to 17 days.

Conclusion:

Radiated Pakistani China peach grown in Khyber Pakhtunkhwa was studied for the first time. No significant difference was observed between controlled and irradiated peach samples. However, storage for more than two weeks is not advisable because of the loss of firmness of fruit.No adverse effect of gamma irradiation was observed in the current study. However, further studies are needed to explore the exact biochemical mechanism of actions.

Keywords: Gamma Irradiation, Peach and Nutritional Components, Peach, Radiation, Ambient Temperature.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."


Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."
