Producing Cherry Tomatoes in Urban Agriculture

In-package atmospheric pressure cold plasma treatment of cherry tomatoes.

Cold plasma is increasingly under research for decontamination of foods, especially fresh fruits and vegetables. The effect of cold plasma on food quality, however, remains under researched. This study investigates the effects of cold plasma generated within a sealed package from a dielectric barrier discharge on the physical quality parameters and respiration rates of cherry tomatoes. Respirat...

Influence of Heat Treatments on Carotenoid Content of Cherry Tomatoes

Tomatoes and tomato products are rich sources of carotenoids-principally lycopene, followed by β-carotene and lutein. The aim of this work was to study the effect of heat treatment on carotenoid content in cherry tomatoes. Raw and canned products were sampled and analysed; furthermore whole, skin and pulp fractions of cherry tomatoes were analysed when raw and home-processed, in order to better...

Urban agriculture

This paper describes the scale and nature of agricultural production in urban, suburban and peri-urban zones of Mexico City and how these have adapted to the changing demands from urban populations for food, wood and recreation. It also demonstrates how agricultural producers have successfully adapted their products and their production methods, including building on traditional production syst...

Shape-based Segmentation of Tomatoes for Agriculture Monitoring

In this paper, we present a segmentation procedure based on a parametric active contour with shape constraint, in order to follow the growth of the tomatoes from the images acquired in the field. This is a challenging task because of the poor contrast in the images and the occlusions by the vegetation. In our sequential approach, considering one image per day, we assume that a segmentation of t...
