Abstract

Abstract: This study aims to evaluate the effects of asparagus pomace with different particle size (~10 μm, ~30 μm, and ~80 μm) on intestinal function and health. One hundred and forty male Kunming mice were divided into fourteen groups and were used for small intestine movement experiment, defecation experiment, and intestinal function and health experiment, respectively. Results showed that, asparagus pomace samples treatment could markedly alleviate the constipation caused by loperamide with improved intestinal propulsion rate, reduced initial time of the first black stool, and increased the total mass of faeces within 6 h ( P < 0.05), and finer samples worked better. All asparagus pomace-treated groups could significantly reduce the cecum ammonia concentration, increase the faeces dry weight and moisture content, and lower the β-d -glucosidase and β-d -glucuronidase activities. However, the difference in aforementioned properties between ~10 μm and ~30 μm groups were not significant ( P > 0.05), and the respective maximal efficiency were observed when the sample was ranged within the size in ~30 μm, which indicated that a rational granularity can meet its objectives. This paper is expected to provide new insights of pulverization on functional properties of fiber-rich food materials. Highlights: Two finer samples (<30 μm) were better for intestinal function and health. There was no significant difference between ~30 μm group and ~10 μm group. Rational processing should be considered rather than pursuing fineness excessively.
