Area Of Science
- Food Science
- Microbiology
- Biochemistry
Background
- Pectin-derived oligosaccharides are emerging prebiotics.
- Dragon fruit pectin's rhamnogalacturonan-I (RG-I) positively affects Bifidobacterium animalis subsp. Lactis 3296 proliferation.
- The specific pectin region responsible for prebiotic effects requires clarification.
Purpose Of The Study
- To investigate the RG-I domain of dragon fruit pectin's role in promoting B. animalis subsp. Lactis 3296 proliferation.
- To characterize the structure of RG-I rich pectin from dragon fruit.
Main Methods
- Gel purification and enzyme digestion to isolate RG-I rich pectin (DP-AC-A2a).
- Monosaccharide analysis and Fourier transform infrared spectroscopy for structural identification.
- Bacterial proliferation assays and enzyme activity measurements.
Main Results
- DP-AC-A2a pectin features a backbone of → 4 GalpA 1-2 Rhap 1 → and galactose-rich branches.
- The galactan component in pectin branches significantly contributes to B. animalis proliferation.
- DP-AC-A2a enhances β-d-galactosidase production by B. animalis.
Conclusions
- Dragon fruit pectin's RG-I domain, particularly its galactose branches, promotes B. animalis proliferation.
- The study identifies specific structural features of pectin responsible for prebiotic activity.
- Findings support the potential application of red dragon fruit pectin as a functional food ingredient.

Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth. Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.
As a cell matures, its cell wall specializes according to its type. For example, the...
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Saliva is a watery substance secreted by the salivary glands into the mouth. Human saliva contains 99.5% water with electrolytes, mucus, white...
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...
