Abstract

Objective: Lansium domesticum Corr. is a fruit tree species belongs to the family Meliaceae. There are numerous forms of the species and grouped into two main types: Duku and Langsat. The objective of this study is to screen the ability of adding extracts of freeze-dried duku and langsat to stimulate the growth and stability of selected Bifidobacteria spp in skimmed milk.Methods: Samples were prepared by adding either 5% or 12% of oligosaccharides from duku, langsat, inulin, galacto-oligosaccharides (GOS) and fructo-oligosaccharides (FOS) to 5% and 12% (w/v) reconstituted nonfat dry milk (NDM), respectively. The specific growth rates (µ) for each sample were calculated. All experiments were replicated ten times.Results: The mean doubling time (Td) for Bifidobacterium longum, was lowest in the presence of freeze-dried duku and langsat compared to GOS, FOS and inulin. Retention of the viability of five Bifidobacterium species was greatest in the presence of freeze-dried duku and langsat followed by GOS, FOS and inulin. The highest percentage of acetic and lactic acids were produced by B. longum, B. infantis and B. adolescentis with freeze-dried duku and langsat. The pattern of results was similar to the commercial product, oligosaccharides (inulin, GOS and FOS). Conclusion: Therefore, this study provides promising results on promoting growth and probiotic activity of natural oligosaccharides compound from freeze-dried duku and langsat.

Highlights

In current years, local species of plant and fruit tree have been scientifically studied for their potential medicinal applications [1]
The results from this study showed a certain stimulatory effect upon addition of fruit prebiotics from duku and langsat on B. longum and B. breve in skimmed milk
Doubling time of Bifidobacterium species grown with prebiotics decreased as compared to the control

Summary

Introduction

Local species of plant and fruit tree have been scientifically studied for their potential medicinal applications [1]. Is a fruit tree species derived from the family of Meliaceae. This popular tropical fruit found mainly in South-East Asia, especially in the Philippines, where it is known as Lanzones, and South Sumatra in Indonesia [2]. It grows in Surinam, Puerto Rico and Australia [3]. There is a fairly clear distinction between the two major types of L. domesticum: Langsat and Duku.
