Postharvest Effects of Temperature and Food Wrap on Three Banana Varieties (Musa sp.) | Chapter 10 | Research Advances and Challenges in Agricultural Sciences Vol. 7

The objective of this study was to determine optimal factors for conservating banana fruit postharvest. Bananas are agricultural products being susceptible to quality changes after harvesting. The experiment was conducted to determine factors affecting storage condition and the ripening process leading to changes in post-harvest quality of 3 popular banana varieties grown in Vietnam within 20 days after harvest. Experimental results showed a statistically significant difference between the three banana varieties: (1) evaluating the influence of temperature and wrapping on the increase or decrease in reducing sugar and soluble solids content of the banana varieties. During storage, fruit samples stored at room temperature rapidly increased the reducing sugar content and soluble solids compared to the original sample after only 2 days of storage; (2) sample volume gradually decreased over storage period. Unwrapped samples at room temperature had a larger mass loss than unwrapped samples at cool temperature; samples using cool temperature wrapping had the least mass loss, only about 3% of the initial mass. The loss of volume and quality of bananas after harvest for many reasons affect farmers' income. At the same period, the results of this project can contribute to limiting post-harvest damage of bananas and prolonging ripening period as well as ensuring the nutritional value and quality of the fruit during storage.

In Modern Diet, Meat and Sugar Food Components Contribute to Worldwide Obesity at Similar Levels | Chapter 4 | Current Research in Agricultural and Food Science Vol. 3

 The public has been told that to prevent obesity, sugar consumption should be reduced, but there is no such guideline for meat. Country-specific levels of obesity and obesity were derived from the Body Mass Index (BMI). These were linked to the per capita per day country-specific availability of major food groups (meat, sugar, starch, fibre, fat and fruit crops), total calories, per capita Gross Domestic Product (GDP PPP), urbanisation and prevalence of physical inactivity. The overlapping of Fisher's r-to-z transformation and Beta (B) spectrum (B ± 2 Standard Error) was used to search for possible variations between the effects of correlations and regressions. The Pearson correlation showed that the supply of sugar and meat both associated substantially with the incidence of obesity to the same degree. In regulating the supply of calories, physical inactivity, urbanisation and GDP PPP, these relationships persisted in partial correlation analysis (r=0.359, p<0.001 and r=0.354, p<0.001 respectively). Fisher's r-to-z transformation showed no substantial difference in Pearson correlation coefficients (z=-0.53, p=0.60), partial correlation coefficients (z=-0.04, p=0.97) between sugar and meat Multiple linear regression analysis found that in both Enter (B=0.455, SE=0.113, p<0.001 and B=0.381, SE=0.096, p<0.001, respectively) and Stepwise (B=0.464, SE=0.093, p<0.001 and B=0.433, SE=0.072, p<0.001, respectively) models, the two most important predictors of obesity prevalence were sugar and meat availability. The overlapping B ranges observed in the Enter (0.289-0.573) and Stepwise (0.294-0.582) models showed no statistically significant difference in the supply of sugar and meat associated with obesity. The availability of sugar and meat is comparably related to the prevalence of global obesity. To stop obesity, dietary recommendations should also recommend minimising meat intake. Taking into account the results of the adverse effects of meat on obesity and the environmental impact of meat processing, similar to the public campaign against unnecessary sugar intake, the national authorities should also warn the public not to follow a high-meat diet for long-term, balanced weight control.
