Abstract Fruits including banana are susceptible to damage especially during transportation. Nipah banana, also known as Musa acuminata balbisiana, has irregular shape and is short in length. This paper focuses on the physical and mechanical properties of Nipah banana. Mathematical models were developed to predict the mass of banana fruit based on the physical properties. Changes during ripening period in terms of the firmness and adhesiveness of Nipah banana were investigated at room temperature (25 °C) for three different positions in a finger. Peak positive and negative force was taken as firmness and adhesiveness, respectively. Results showed that the multiple regression modelling based on three dimensions had the highest R2 value. Values of firmness and adhesiveness decreased with the ripening days due to starch degradation and accumulation of soluble sugars. A similar trend was observed on the firmness for all three positions.

果实位置对香蕉品种 Nipah 硬度和附着力的质量建模及影响

摘要 包括香蕉在内的水果很容易受到损坏，尤其是在运输过程中。Nipah香蕉，也被称为Musa acuminata balbisiana，形状不规则，长度短。本文重点研究尼帕香蕉的物理和机械性能。开发了数学模型以根据物理特性预测香蕉果实的质量。在室温 (25 °C) 下，针对手指的三个不同位置，研究了成熟期间 Nipah 香蕉硬度和粘性的变化。峰值正负力分别被视为坚固性和粘附性。结果表明，基于三个维度的多元回归建模具有最高的R2值。由于淀粉降解和可溶性糖的积累，硬度和粘性值随着成熟天数而降低。在所有三个职位的稳固性上都观察到了类似的趋势。
