Abstract

Background: Mangosteen (Garcinia mangostana L.) is recognized for its immunomodulatory properties, which can rejuvenate, regulate, and modulate immune system function. As a rich source of antioxidants, mangosteen peel has the potential to enhance immune responses and improve overall health status. However, further investigation into the biological mechanisms underlying its immunomodulatory effects remains limited. Objectives: This review aims to explore the various biological functions of mangosteen peel related to immunomodulation and examine its therapeutic potential in improving human health. Methods: A Systematic Literature Review (SLR) was conducted, focusing on articles published between 2013 and 2023. From a total of 132 articles identified, ten were selected based on relevance and research quality. Discussions: The review reveals significant associations between the properties of mangosteen peel, such as its anti-diabetic, anti-obesity, antidepressant, anti-inflammatory, anticancer, and antioxidant activities, and the complex network of immune cell responses. Nevertheless, most studies have not clearly identified the specific compounds responsible for these immunomodulatory effects, and the underlying mechanisms remain unclear. Further comprehensive studies are necessary to isolate and identify the bioactive compounds in mangosteen peel extract, beyond xanthones, to better understand their diverse therapeutic effects and mechanisms. Well-designed clinical trials involving diverse populations, including vulnerable groups, are essential to validate the efficacy and safety of the extract in various therapeutic contexts. Conclusions: This review provides valuable insights into the potential of mangosteen peel as an immunomodulator and lays the groundwork for future research aimed at utilizing its therapeutic properties to improve human health.

Abstract

Graphical Abstract Highlight Research Fermentation improves the biological function of proteins. Bioactive peptides increase after fermentation. Indonesia has many unexplored sources of bioactive peptides in fermented food. Indonesian high-protein fermented foods have high bioactivity potential. Research is needed on the bioactivity of Indonesian bioactive peptides sources for broader health implications.     Abstract Bioactive peptides (BPs) are short protein fragments with significant physiological functions, including antioxidant, antihypertensive, antimicrobial, and antidiabetic activities. These compounds are commonly released during fermentation, making high-protein fermented foods (HPFF) a promising source of natural health-promoting agents. Indonesia, with its rich biodiversity and long-standing tradition of fermentation, offers a unique variety of traditional HPFF. However, the potential of these indigenous products as BP sources remains underexplored and poorly represented in the global literature. This review aims to examine Indonesian traditional HPFF as a source of BPs, categorize them based on raw material, and highlight their functional and health-related properties. A literature review was conducted using publications from Scopus, PubMed, ProQuest, Google Scholar, and SINTA (2000–2023). The search applied Boolean strategies and the PEO (Population, Exposure, Outcome) framework to identify relevant studies on fermented foods, bioactive peptides, and their biological activities. Indonesian HPFF including tempeh, rusip, dangke, pekasam, and cangkuk contain BPs with diverse bioactivities. Tempeh shows antidiabetic and antihypertensive potential; rusip exhibits antioxidant and cholesterol-lowering effects; dangke and cangkuk demonstrate antimicrobial and ACE-inhibitory activities. These functional properties are influenced by substrate type (e.g., legumes, fish, milk), microbial composition (lactic acid bacteria, Bacillus spp., yeasts), and fermentation conditions. Notably, certain Indonesian HPFF exhibit multi-functional peptides with synergistic health effects, suggesting significant therapeutic promise. This review bridges a critical knowledge gap by consolidating evidence on BPs from Indonesian HPFF. It provides a foundation for future investigations into peptide bioactivity, supports functional food innovation, and highlights the global relevance of Indonesia’s fermentation heritage in health science and sustainable nutrition.

Abstract

The tempeh available on the market is predominantly made from imported soybeans, but alternative formulations using locally sourced legumes, such as koro kratok (Phaseolus lunatus), have been explored. This study investigates the potential of koro kratok tempeh enriched with Plunchea indica (beluntas) leaves to improve its functionality. The study will evaluate gamma-aminobutyric acid (GABA) levels and physicochemical changes during fermentation. Tempeh was produced using different koro kratok-to-P. indica leaf ratios (100:0, 75:25, and 50:50). Key parameters observed included mycelium development and the content of fat, moisture, ash, protein, carbohydrates, and pH. Adding P. indica increased the fat content by 0.66–2.28%, the moisture content by 68.81–78.42%, and the ash content by 0.36–1.09%. Meanwhile, the protein content ranged from 6.62–8.87%, the carbohydrate content from 12.07–21.31%, and the pH between 4.21–4.25. The inclusion of P. indica also altered the profile of dominant volatile compounds. GABA was detected in all samples, and in vivo studies showed improved blood glucose levels and glucose tolerance in prediabetic rats. These results suggest that koro kratok tempeh enriched with P. indica leaves could be a promising functional food for regulating blood glucose.
