Abstract

Beberapa orang menghindari susu hewani, yaitu seperti penderita intolerasi laktosa dan vegetarian. Berdasarkan masalah tersebut, yoghurt berbahan dasar susu nabati dari kedelai atau biasa disebut dengan soyghurt dapat menjadi solusi. Jenis karbohidrat yang digunakan sebagai sumber energi pertumbuhan bakteri adalah madu. Tujuan penelitian ini adalah untuk menganalisis pengaruh konsentrasi penambahan madu yaitu 0,0%, 2,5%, 5,0%, 7,5%, 10,0%, 12,5% terhadap karakteristik fisik (pH dan kekentalan) dan organoleptik soyghurt. Tahapan yang dilakukan adalah pembuatan susu kedelai kemudian pembuatan soyghurt. Data dianalisis menggunakan metode One-Way ANOVA dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa terdapat perbedaan nyata pH pada konsentrasi madu 7,5% dan 10% dengan nilai penurunan sebesar 4,85. Perbedaan nyata viskositas terlihat pada konsentrasi madu 5% dengan nilai peningkatan sebesar 6,3 dpa.s. Perbedaan nyata karakteristik organoleptik terlihat pada parameter rasa, tekstur dan keseluruhan dengan tingkat kesukaan tertinggi terdapat pada konsentrasi madu 12,5%. Penambahan madu dengan konsentrasi yang berbeda (0,0-12,5%) memberikan pengaruh nyata pada pH, viskositas dan tingkat kesukaan panelis terhadap sifat organoleptik khususnya untuk parameter rasa, tekstur dan keseluruhan soyghurt.

Abstract

This study evaluated the effects of botanical water from various raisin varieties on the sensory and textural qualities of sourdough bread. Black, green, and yellow raisins were used to make botanical water, which was then used as a natural fermentation medium. Conventional sourdough was used as the control. Hardness, cohesiveness, springiness, gumminess, chewiness, fracture force, adhesiveness, and stiffness were all measured by texture analysis. Fifty-five untrained panelists used a five-point hedonic scale to rate sensory acceptance. Significant differences were noted in hardness, springiness, gumminess, and stiffness; however, other textural parameters showed no significant variation. Hardness, gumminess, springiness, and stiffness values were highest in sourdough made with yellow raisin botanical water, while the control had the lowest hardness. The sourdough samples stayed within the acceptable range in the sensory evaluation, but the control sample scored highest for color, texture, and overall acceptability. Among the botanical water treatments, green raisin sourdough was the most well-liked. According to the findings, raisin botanical water has an impact on bread structure and fermentation behavior, resulting in quantifiable texture changes and mild variations in sensory perception. Therefore, it is possible to use botanical water from raisins as a natural fermentation medium for making sourdough bread without experiencing severe sensory rejection.
