Peeling is one of the first operations in the manufacture of whole peeled and diced tomatoes, and the peelability of processing tomatoes is significantly affected by the presence of various tomato defects, in particular yellow eye and blossom-end rot. Tomato maturity also impacts both the percentage of peeled fruit and yield. Immature fruits are typically undercolored and small in size. Sunburn...

abstract         background and objective: hirudin is an anticoagulant polypeptide secreted from the salivary glands of leeches. recombinant hirudin is a strong anticoagulant agent in arterial and venous thrombosis. the aim of this study was to evaluate the effect of inserting protein a signal peptide sequence of pezz18 plasmid on expression and secretion of the recombinant hirudin in e.coli.  ...

The conventional method of grading Harumanis mango is time-consuming, costly and affected by human bias. In this research, an in-line system was developed to classify Harumanis mango using computer vision. The system was able to identify the irregularity of mango shape and its estimated mass. A group of images of mangoes of different size and shape was used as database set. Some important featu...

Grading of agricultural produce especially the fruits and vegetables has become a perquisite of trading across borders. In India mostly fruit and vegetable growers grade the fruit manually. Manual grading was carried out by trained operators who considered a number of grading factors and fruit were separated according to their physical quality . Manually grading was costly and grading operation...

Pathogens feed on fruits and vegetables causing great food losses or at least reduction of their shelf life. These pathogens can cause losses of the final product or in the farms were the products are grown, attacking leaves, stems and trees. This review analyses disease detection sensors and algorithms for both the farm and postharvest management of fruit and vegetable quality. Mango, avocado,...

In this paper we introduce a cascaded-classifier approach to localize stem-ends and calyxes of ‘Jonagold’ apples. First classifier (artificial neural network) extracts candidate objects, whereas the second one (nearest neighbor) discriminates stem-ends and calyxes from others. Overall system is tested by 616 fruits from which first classifier found 414 candidate objects. Several features are ex...

Enterovirus 71 (EV71) causes seasonal epidemics of hand-foot-and-mouth disease associated with fatal neurological complications in young children, and several major outbreaks have occurred recently. This study developed an effective antiviral agent by transforming the gene for VP1 protein, a previously defined epitope and also a coat protein of EV71, into tomato plant. VP1 protein was first fus...

Image processing has been proved to be effective tool for analysis in various fields and applications. Agriculture sector where the parameters like canopy, yield, quality of product were the important measures from the farmers’ point of view. Many times expert advice may not be affordable, majority times the availability of expert and their services may consume time. Image processing along with...
