Banana is practically non-seasonal crop that reliably grown by local farmers primarily for food. It has been categorised as the dessert bananas and the cooking bananas. Cooking banana is one of the most important staple food and cash crops in East Africa. It plays a central role in food security; it serves as a source of carbohydrate, minerals and vitamins all year- round. The banana crop provides a household annual income of about $ 1,500; this is the highest smallholder income-generating crop in the region. Currently, several indigenous and improved cultivars exist in East Africa.

Raymond Kessler, Jr., Professor of Horticulture Esendugue Greg Fonsah, Professor and Extension Specialist of Agriculture and Applied Economics, University of Georgia, Tifton Campus, Tifton, GA 31793 Abstract There has been increased interest in growing and selecting cold-hardy short- season cultivars to offer an alternative to the industry standard, the Cavendish (genome AAA). In addition to expansion of production, these specialty cultivars have advantages such as increased nutritional qualities, resistance to disease, and favorable postharvest attributes. The determination of suitable alternatives to the Cavendish subgroup is a relatively new concept; therefore very little research has been done regarding the postharvest and nutritional properties of these specialty cultivars. The goal of the first experiment was to determine the effect of common postharvest practices and length of storage on the quality and nutrition of specialty bananas grown in the southeastern

  • Phytonutrient Bioaccessibility and Metabolism in Vitro and in Vivo Dorrain Low Yanwen B.App.Sci
    Phytonutrient bioaccessibility and metabolism in vitro and in vivo Dorrain Low Yanwen B.App.Sci. (Food Science and Nutrition) (Hons) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2015 Queensland Alliance for Agriculture and Food Innovation, Centre for Nutrition and Food Sciences. i Abstract Mangoes and bananas, two of Queensland’s major tropical crops are sources of bioactive phytonutrients linked to dietary health based on antioxidant, cardio-protective and vasodilatory properties. Bioaccessibility of macro-, micro- and phytonutrients from whole foods is first determined by mastication followed by gastrointestinal liberation from food matrices (cell wall and membrane). Intact plant cell walls effectively encapsulate cellular components e.g. starch, lipid, protein, carotenoids and polyphenols, physically preventing entry of the mammalian digestive system, which is unable to enzymatically break down plant cell walls. Once bioaccessible, ‘free’ nutrients are available for absorption, while the unreleased fraction travels to the colon for fermentation. Nutritional recommendations are usually based on extracted contents of raw plant material; therefore true dietary concentrations have not been well established. This thesis focuses on studying the effects of sequential digestive processing of mango (Kensington Pride) and banana (Cavendish) flesh in the mouth, stomach, small intestine and colon using in vitro and in vivo approaches. In vitro nutrient bioaccessibility studies often favour mechanical processing over mastication. Investigating the effect of mastication (Chapter 3) in mango demonstrated microstructural changes, conferring a range of chewed particle sizes (large particle clusters to cell fragments). Actions not replicable with a cutting blade i.e. compression, squashing and formation of bolus were observed in these masticated particles, collectively enhancing encapsulation of carotenoids.

  • Chapter 1 Genetic Improvement of Banana
    Chapter 1 Genetic Improvement of Banana Fred´ eric´ Bakry, Franc¸oise Carreel, Christophe Jenny, and Jean-Pierre Horry 1.1 Introduction World production of bananas, estimated at 106 million tons (Lescot 2006), ranks fourth in agricultural production. Bananas make up the largest production of fruits and the largest international trade, more than apple, orange, grape and melon. Bananas are cultivated in more than 120 countries in tropical and subtropical zones on 5 continents. Banana products represent an essential food resource and have an important socioeconomic and ecological role. Current varieties are generally seedless triploid clones either of the single genome A from the species Musa acuminata (group AAA) or of both genomes A and B from species M. acuminata and Musa balbisiana (groups AAB and ABB). More rarely, diploid varieties (AA and AB) and tetraploid clones are encountered. There are two major channels of banana production: those cultivated for export and those reserved for local markets. The main banana varieties cultivated for export, known as ‘Grande Naine’, ‘Poyo’ and ‘Williams’, belong to the monospecific triploid bananas (AAA) of the Cavendish sub-group. They differ from each other only in somatic mutations such as plant height or bunch and fruit shape. Their production relies on an intensive monoculture of the agro-industrial type, without rotation, and a high quantity of inputs. Banana cultivation for local consumption is based on a large number of vari- eties adapted to different conditions of production as well as the varied uses and tastes of consumers. Diploid bananas, close to the ancestral wild forms, are still cultivated in Southeast Asia.

Analyses were conducted using the standard methods to ascertain their potential in food-based strategies in order to improve nutrition- sensitive agriculture, address hidden-hunger. Data were subjected to analysis of variance and means were compared. There were significant differences in all parameters assessed. Results further indicated that the moisture content ranged from 65.53 to 74.44 g/100 g; ash 0.66 to 1.45 g/100 g; fat 0.1 to 0.6 g/100 g; fibre 0.9 to 2.8 g/100 g; carbohydrate 21.6 to 30 g/100 g. Mineral content ranged from 306 to 469 mg/100 g; 2.6 to 6 mg/100 g; 0.4 to 0.8 mg/100 g and 0.1 to 0.2 mg/100 g for K, Ca, Fe and Zn, indicating potential nutritional significance.
