The quality concept has changed considerably over the last decade. What are the visible results of this change in agricultural and food sectors, where markets and organizations are closely meshed in economic units - commonly referred to as filieres in France? The present paper highlights that the total quality control concept, developed in the field of management, has profoundly changed...
Banana quality varies widely throughout the year in West Indian banana plantations, especially those located in lowland areas. Anthracnose, caused by the pathogen Colletotrichum musae, develops on the fruit peel during shipping operations and as the bananas ripen. Yields from two plantations, located at two separate sites representative of special geographic zones in Guadeloupe, were monitored for...
According to an analysis of the onion subsector in Niger, Benin, Burkina Faso and Cote-d'Ivoire, carried out from April 1994 to July 1995, those involved in this subsector have different and sometimes even contradictory quality criteria, depending on their objectives and interests: producers try to grow large bulbs, while merchants mainly look for small onions that can better withstand storage and...
Onions only recently began being produced in New Caledonia. Quality is gradually becoming an important production concern, based on the results of research aimed at improving this parameter. The onion subsector includes farmers under contract with the Office de commercialisation et d'entreposage frigorifique (Ocef), along with research and extension agencies responsible for developing cropping practices...
A technical study of post-harvest conditions in the cut flower sector highlighted factors that lower the quality of these products, thus hampering market development. An inventory was drawn up of tropical and temperate flower species grown on the island and commonly sold as cut flowers. The roles of professional agents, producers and retailers were analyzed. The study closely investigated different...
Farm products can only be labelled organic if they comply with a special European regulation (1993) concerning plant products, and if they have been controlled by an independent organization. Production, cropping, harvesting and processing conditions should be checked regularly and the label has to be fully informative for the consumer. Certification that a product is of organic quality means...
Mali was the first country to begin exporting mangos (around 1970), followed by Cote d'Ivoire (early 1980s). Mango production structures have developed to address European market expectations and price fluctuations. The quality concept was gradually developed on the basis of criteria such as mango shape, color and size. This led to the creation of new varieties, with cv Kent at the forefront, and...
The concept of total quality management is described with reference to international standards in quality assurance. The relevance of quality management for horticultural products is explained in the context of legislation governing horticultural marketing in Europe, trends in consumer demands and market competition. The Natural Resources Institute's recent activities in supporting implementation...
There have been many recent research investigations aimed at developing advanced technologies to improve the aromatic qualities of food products. The present study focused on the release of terpenes from β-glycosylate precursors using a β-glucosidase enzyme complex. Hydrolysis analyses using exocellular β-glucosidase from Candida cacaoi revealed that this enzyme was able to release a fraction of...
In a study conducted by CRBP in Cameroon, the physicochemical fruit qualities of 24 plantain cultivars and hybrids, along with those of other bananas grown for self-consumption (cooking and dessert bananas), were determined. A number of parameters concerning clone yields and fruit quality were measured and variations in these characteristics were monitored from harvest to ripeness stage 7 (yellow...
Onion production has been progressing in France over the last 10 years, especially yellow onions which can withstand long storage. This increased production is the result of better control of quantities produced, and especially the maintenance of product quality throughout the season. However, both supply and demand are highly dispersed, despite the existence of a few important marketing structures...
Formulations or techniques for processing fruit-based products can be optimized through texture measurements, thus helping to improve the organoleptic or technological qualities of the product. However, the structural heterogeneity of most fruits is a major obstacle that has to be overcome to obtain reliable results. Each study leads to the development of a specific empirical method. Two applications...
In recent years, various activities have been conducted in the vegetable subsector, with the aim of supplying products that meet consumers' expectations, as defined in market surveys on tomato, onion and potato. Some farmers' production techniques were improved to ensure that the shapes and colors of these vegetable products would be regular throughout the year. Consumers' expectations were highlighted...
Introduction. The short period of storage of the yellow passion fruit, a climacteric fruit, is a limiting factor for its commercialization. In order to harvest mature but not ripe fruits and, thus, extend the conservation time, research has been aimed at characterizing developmental stages of the fruit and find indexes to apply to harvest time. Materials and Methods. Fruits of known age, obtained...
Introduction. Identification and description of breadfruit germplasm with commercially important traits are necessary to stimulate new plantings in the Carribean, to supply the export market with increased quantities of high quality fruits. This study was a step towards obtaining this information. Materials and Methods. Two surveys were conducted throughout St Vincent. Varieties were identified...
Introduction. In Southeast Asia, durian fruit is valuable culturally, socially and commercially. Distribution. Durio zibethinus Murr, the most common Durio species, is cropped in Southeast Asia, the area from which it originates. Durian seeds have been introduced on other continents. Cropping. Durian is grown traditionally in monospecific orchards of improved varieties. Propagation. Sexually-propagated...
