Abstract

Tofu from Lembang, Tofu from Sumedang and Tofu from Garut are three types tofu that are produced in different places, but still close. Although made from the same raw material that is soy, every tofu will produce a different tofu, both in terms of taste, aroma, texture and suppleness. Differences in the type of flavour compouds used can also be a factor causing divergence of any tofu product. The characteristic of the tofu were determined by identifying the flavour compouds GC-MS, as well as organoleptic tests. To determine differences in compound-producing falvour in the tofu. The results extraction method was carried out on tofu samples using n-pentane as solvent then analyzed using GC-MS. Flavour compounds of all three types of tofu included into the ester group, alkenes and aldehydes. Organoleptic tests show that the panelists prefered. Tofu from Sumedang for test of colour appearance (82%), for the test texture panelists like Tofu from Garut (83%), for test of elasticity panelists prefered Tofu from Garut Lembang (75%), for taste test panelists prefered Tofu from Lembang (88%), panelists prefered Tofu from Lembang for flavour test (82%).

Abstract

Karies gigi merupakan masalah kesehatan mulut yang dialami 3,5 miliar orang di dunia. Karies gigi disebabkan oleh adanya aktivitas dari bakteri Streptococcus mutans. Temu mangga (Curcuma amada) yang mengandung senyawa kurkuminoid dan xylitol diketahui berpotensi menghambat pertumbuhan bakteri Streptococcus mutans. Maka dari itu, dilakukan pengembangan produk olahan pangan fungsional berbentuk fruit leather berbahan dasarkan temu mangga (Curcuma amada) dan xylitol yang diketahui memiliki aktivitas antibakteri dan berpotensi menghambat bakteri Streptococcus mutans sebagai penyebab karies gigi. Pada penelitian ini dilakukan pembuatan fruit leather dengan lima variasi penambahan temu mangga dan xylitol yaitu 80:20, 70:30, 50:50, 30:70, 20:80%, lalu dilakukan analisis karakteristik, uji organoleptik dan uji aktivitas antibakteri. Metode yang digunakan untuk mengetahui karakteristik meliputi penentuan kadar air (metode thermogravimetri), jumlah gula (sukrosa) (metode luff schoorl), kadar cemaran logam menggunakan instrumen AAS (Atomic Absorption Spectrophotometer). Metode yang dilakukan untuk mengetahui aktivitas antibakteri yaitu difusi cakram. Hasil penelitian menunjukkan variasi rasio penambahan temu mangga dan xylitol mempengaruhi kadar air, jumlah gula (sukrosa), dan cemaran logam. Semakin besar penambahan temu mangga meningkatkan kadar air, dan menurunkan nilai kadar gula, sebaliknya dengan xylitol. Selain itu, variasi rasio penambahan temu mangga dan xylitol mempengaruhi karakteristik sensoris fruit leather yang dapat dilihat dari parameter warna, tekstur, rasa dan aroma. Variasi fruit leather yang paling banyak disukai panelis yaitu variasi 20:80% dengan variasi penambahan xylitol terbesar. Nilai aktivitas antibakteri terbesar yaitu dengan zona hambat sebesar 7,10 mm dimiliki oleh variasi 80:20% dengan variasi penambahan temu mangga terbesar.
