Nutritional and sensory characteristics of local and hybrid East African Highland cooking bananas: Implications for breeding programs

JSFA reports, EarlyView.
Abstract Background Bananas (Musa species) are an important staple food and cash crop in many parts of the world. The East African Highland cooking bananas form the backbone of food security for millions of Ugandans. The demand for high quality cooking bananas is thus closely linked to their sensory characteristics (which drive consumer preference) and

Black flesh disorder in mango: a chilling injury symptom increased by early harvest and low storage temperature and reduced by 1‐methylcyclopropene

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Black flesh (BF) is an internal disorder in mango, characterized by the development of dark brown to black pigmentation in the inner mesocarp tissue during storage or transport. This study investigated the effects of harvest maturity, low storage or low transport temperatures, and 1‐methylcyclopropene (1‐MCP) on mango fruit ...
