Abstract

Prebiotics are compounds with the ability to specifically enhance the population of advantageous bacteria in the gastrointestinal tract. Starch is a polysaccharide which has prebiotic activity. Agricultural waste like banana peel contains prebiotic polysaccharides including starch. The prebiotic effect of starch from many varieties of banana peel has been explored by researchers. Although Ambon banana is a variety that is commonly consumed in Indonesia, the prebiotic activity of its peel, particularly the peel starch,  has not been studied yet. Thus, this study aims to research the prebiotic activity of Ambon banana peel starch against probiotic bacteria of the Lactobacillus acidophilus and the opportunistic pathogen bacteria of Eschericia coli. In this research, starch was extracted from banana peel (var. pisang Ambon) and prebiotic activity of the starch was tested on L. acidophilus and E. coli.  The number of bacteria was calculated at 0 and 24 hours of incubation using plate count methods.The result showed that at the concentration of 1% w/v, Ambon banana peel starch increases the number of L. acidophilus while inhibiting the growth of E. coli. The L. acidophilus culture in the starch-containing media had SCFAs (acetic, butyric and propionic acid) that were  known to have good impact to human health.

Abstract

Propionibacterium acnes is a bacteria which causes acne. This bacteria is hypothesized to be inhibited by Staphylococcus epidermidis. Prebiotics have been shown to enhance the number of S. epidermidis and decrease the growth of P. acnes. The prebiotic action of starch and pectin from diverse plant sources is known in the skin microbiome. The prebiotic activity of Ambon banana peel starch and pectin on skin microbiota has not been researched. This study aims to investigate the prebiotic activity of starch and pectin from Ambon banana peels on skin microbiota, represented by S.epidermidis and P.acnes. The results showed that starch, and pectin have a prebiotic activity because they promoted the growth of S. epidermidis while suppressing the growth of P. acnes. P. acnes inhibitor percentages were 1.62% for starch and 65.07% for pectin. Negative inhibition values were -184.95% for starch and -5.80% for pectin suggesting an increase in S. epidermidis proliferation.

Abstract

Purple sweet potatoes are recognized for their prebiotic properties including againts Lactobacillus casei and L. bulgaricus bacteria. This prebiotic effect is due to the high starch content in purple sweet potatoes. The amylose content in starch which is difficult to digest in gastointestinal tract, functions as a prebiotic. To enhance the prebiotic effect of purple sweet potato starch, modification into resistant starch can be performed. Resistant starch exhibits a higher prebiotic effect compared to regular starch because it cannot be broken down by digestive enzymes, allowing it to reach the large intestine in significant amounts. Additionally, the prebiotic effect can be further enhanced by creating mucoadhesive granule formulations that increase the contact time of a substance on the mucosa of the digestive tract. This study aims to evaluate the prebiotic effect of resistant starch from purple sweet potatoes and to develop its mucoadhesive granule formulation. The resistant starch from purple sweet potatoes was prepared using the heat moisture treatment method. The prebiotic activity of resistant starch was tested against Lactobacillus acidophilus and Escherichia coli. The granule formulation was prepared by varying the concentration of polymers used, namely a combination of HPMC and carbopol as mucoadhesive polymers. The results showed that resistant starch from purple sweet potatoes had a prebiotic index of 0.930. The granule formulation F3 with an HPMC and Carbopol polymer ratio of 1:2 was identified as a good mucoadhesive granule formulation. It met pharmaceutical evaluation with a mucoadhesive percentage value of 40%.

Abstract

Prebiotics, including carbohydrates and phenols, promote beneficial gut bacteria (probiotics). Red ginger (Zingiber officinale var. rubrum) rhizomes, rich in these compounds, have been traditionally used in medicine but their prebiotic potential remains unexplored. This study investigated the in vitro prebiotic effects of Z. officinale var. rubrum rhizomes on Lactobacillus acidophilus (beneficial) and Escherichia coli (opportunistic) bacteria. Prebiotic activity was assessed using a turbidimetric method, measuring bacterial growth via UV-Vis spectrophotometry at 600 nm. The prebiotic index and percentage inhibition were calculated to evaluate the impact on bacterial growth. Additionally, total phenol content was determined using the Folin-Ciocalteu method. Results indicate that Z. officinale var. rubrum rhizomes exhibit prebiotic properties, stimulating L. acidophilus growth (prebiotic index of 156.035 and percentage inhibition value of -153.128%) while inhibiting E. coli growth (54.343% inhibition). The rhizomes contained 31.15 mg GAE/g extract of total phenols and 23.55% carbohydrates. These findings suggest that Z. officinale var. rubrum rhizomes possess prebiotic potential, warranting further investigation for potential applications in gut health management.
