Fermentation is widely used in the processing of dairy, meat, and plant products. Due to the growing popularity of plant diets and the health benefits of consuming fermented products, there has been growing interest in the fermentation of plant products and the selection of microorganisms suitable for this process. The review provides a brief overview of lactic acid bacteria (LAB) and their use in fermentation of legumes and legume-based beverages. Its scope also extends to prebiotic ingredients present in legumes and legume-based beverages that can support the growth of LAB. Legumes are a suitable matrix for the production of plant-based beverages, which are the most popular products among dairy alternatives. Legumes and legume-based beverages have been successfully fermented with LAB. Legumes are a natural source of ingredients with prebiotic properties, including oligosaccharides, resistant starch, polyphenols, and isoflavones. These compounds provide a broad range of important physiological benefits, including anti-inflammatory and immune regulation, as well as anti-cancer properties and metabolic regulation. The properties of legumes make it possible to use them to create synbiotic food, which is a source of probiotics and prebiotics.

Daluga (Cyrtosperma merkusii. (Hassk.) Schott) adalah salah satu jenis tanaman umbi kaya karbohidrat yang berasal dari Kepulauan Siau, Manado, Sulawesi Utara. Kandungan pati daluga yang tinggi berpotensi sebagai bahan baku pembentukan pati resisten (Resistant starch/RS). Tujuan dari penelitian ini adalah meningkatkan kadar RS tepung daluga melalui modifikasi Heat Moisture Treatment/HMT dan fermentasi Bakteri Asam Laktat/BAL serta mengkaji pengaruh modifikasi terhadap sifat fisikokimia tepung daluga modifikasi. Penelitian terdiri dari 3 perlakuan antara lain HMT menggunakan oven (100 ̊C, 16 jam), autoklaf (121 ̊C, 60 menit), dan kombinasi fermentasi BAL dengan Lactobacillus plantarum BSL dan HMT. Berdasarkan hasil analisis, tepung daluga hasil modifikasi oven, autoklaf, dan Lactobacillus plantarum BSL + HMT memiliki kadar RS masing-masing sebesar 7,14; 8,81; 5,31% (db). Hasil modifikasi tepung daluga juga berpengaruh terhadap kadar serat pangan, amilosa, serta perubahan viskositas dan suhu gelatinisasi. Kesimpulannya, tepung daluga dengan modifikasi HMT dan fermentasi bakteri asam laktat dapat memberikan pengaruh yang bervariasi pada berbagai sifat fisikokimianya.Physicochemical Characteristics of Modified Daluga Flour (Cyrtosperma Merkusii. (Hassk.) Schott) by Lactic Acid Bacteria Fermentation and Heat Moisture TreatmentAbstractDaluga (Cyrtosperma merkusii. (Hassk.) Schott) is one of the tubers originated from the Siau Islands, Manado, and North Sulawesi. The starch contents of daluga which were quite and have the potency as raw materials for starch resistant (SR) formation. The objectives of this research were to increase the SR content of daluga flour, to obtain a modified flour with Lactic Acid Bacteria (LAB) fermentation and Heat Moisture Treatment/HMT of daluga flour and to examine the effect of HMT and LAB fermentation on physicochemical characteristics of daluga flour. The study consist of 3 treatments of HMT, i.e. oven (100°C, 16 hours), autoclave (121° C, 60 minutes), and combination of LAB fermentation by Lactobacillus plantarum BSL and HMT. The result showed the specific value of RS from oven, autoclaves and LAB treatment i.e. 7.14, 8.81, 5.31%, respectively. The results of modified daluga flour could affect dietary fiber, amylose contents, viscosity and gelatinization temperature. As conclusion, modified daluga flour with HMT treatment and fermentation might provide specific result on its physicochemical characteristics.

<p class="Abstrak"><span lang="EN-GB">The banana of CV. Mas Kirana off-grade can be processed into banana flour with high resistant starch content which functions as a prebiotic. This study aims to optimize the content of resistant starch (RS) type 3 in the produce of banana flour. Modified banana flour cv. Mas Kirana with highest RS content will then be used to substitute skim milk in making prebiotic banana yogurt and are analyzed for its sensory properties. Data were processed using design expert 11.0 with three factors, namely X1 (Lactic acid bacterial concentration (LAB), X2 (fermentation time), X3 (retrogradation time). The optimization result was 10<sup>9</sup> CFU/mL of lactic acid bacteria concentration, 24 hours of fermentation time, and 37,60 hours of retrogradation time. The resulting banana flour cv Mas Kirana has 83,95% of resistant starch, 29,24% of yield, 3,60 of logarithmic lactic acid bacteria, and 4,49 of pH value. Its application to the production of banana yoghurt prebiotic replacing 80% skim milk, was acceptable to panelists in terms of color, aroma, viscosity, taste, and overall acceptance.</span></p>
