Abstract

The dependence of Indonesian people on consumption of wheat flour is high. In addition, wheat flour contains gluten, but not everyone can consume gluten. Indonesia has local food ingredients that can replace wheat flour, one of which is sorghum flour. Making cookies using sorghum flour and almond flour produces gluten-free cookies that are safe for people with gluten intolerants and lactose intolerants. In making cookies, a sweetener is needed, which can be used stevia sugar and crystal coconut sugar. The research aims to: 1) determine the effect of the proportion of sorghum flour and almond flour on the physical and chemical properties of cookies, 2) determine the effect of the proportion of stevia sugar and crystal coconut sugar on the physical and chemical properties of cookies, 3) determine the formulation of sorghum flour and almond flour with the addition of stevia sugar and crystal coconut sugar to produce cookies of the highest quality in terms of physical and chemical properties. The research used factorial randomized block design. The factors studied were the proportion of sorghum flour: almond flour consisted of 3 levels (1: 1; 2: 1; and 3: 1); and the proportion of stevia sugar: crystal coconut sugar consists of 3 levels (2: 1; 1: 1; 1: 2). The variables observed included ash content, moisture content, fat content, dissolved protein content, reducing sugar content and swelling volume. The best treatment is selected using the effectiveness index test. The results showed that the proportion of sorghum flour: almond flour affected the moisture content, ash content, fat content and dissolved protein content of cookies. Comparison of stevia sugar: crystal coconut sugar has an effect on water content, fat content, and reducing sugar content in cookies. The interaction between the two does not affect all variables. Based on chemical and physical variables, the selected treatment was a combination of T1K2 (sorghum 1 flour: almond flour 1 and stevia sugar 1: crystal coconut sugar 1). The physicochemical characteristics of cookies with sorghum flour and almond flour produced from the best treatment combination had a moisture content value of 4.45%, an ash content of 1.04%, a fat content of 33.57%, a dissolved protein content of 1.17%, a reducing sugar content of 5, 91%, and development volume of 60.48%

Abstract

Pragelatinisasi merupakan metode modifikasi yang dapat diterapkan untuk tepung jagung sehingga diharapkan dapat mempermudah pada proses pembuatan mi. Suhu gelatinisasi berbeda-beda bagi tiap jenis pati, dan untuk mencapai suju gelatinisasi tersebut tiap bahan memerlukan waktu yang berbeda. Setiap bahan juga membutuhkan penambhan air yang tepat agar dapat mengalam gelatinisasi. Penelitian ini bertujuan untuk (1) mempelajari kombinasi wkatu dan suhu pemasakan serta jumlah air yang ditambhakan untuk suspensi tepung jagung pragelatinisasi yang mempunyai respon maksimum terhadap kadar karbohidrat, kadar pengembangan dan tingkat penerimaan mi jagung; (2) mengetahui karakter fisiokimia dan organoleptik mi jagung pada formula optimal. Hasil penelitian menunjukkan bahwa ondisi pragelatinisasi optimal pada tepung jagung untuk pembuatan mi adalah selama pemasakan 7 menit waktu pemasakan, suhu 71C dan volume air 13% b/v. Mi jagung formula optimal memiliki kadar air 62,61%; kadar abu 0,322% bb; kadar lemak 1,37% bb; kadar protein total 4,18% bb; kadar karbohidrat 31,51% bb; daya pengembangan mi 16,67%; warna 2,5 9kuning keputihan); aroma 3,9 (tidak khas tepung); tekstur (2,5) (agak kenyal); rasa 2,6 (agak gurih); dan tingkat kesukaan keseluruhan 2,8 (suka). mi jagung ini masih memerlukan perbaikan proses untuk menurunkan kadar air yang tinggi, supaya memenuhi SNI 01-2987-1992. Pragelatinization is a modification method that can be applied for corn flour so that it can simplify the application for noodles. The temperature of gelatinization varies for each type of starch, and to reach the gelatinization temperature each ingredient needs different time. Each ingredient also needs the precise amount of water to get gelatinization. The object of this research are (1) to study the combination of cooking time and temperature and the amount of water needed for the suspension of pragelatinized corn flour which has a maximum response to carbohydrate levels, swelling power and preference of corn noodles; (2) to study the physicochemical and sensory characters of corn noodles in the optimal formula. The results showed that the optimal pregelatinization condition in corn flour for the production of noodles was during 7 minutes cooking time, temperature 71oC and volume of water 13% b / v. The optimal formula for corn noodles has a water content of 62.61%; ash content 0.322% bb; fat content 1.37% bb; total protein content 4.18% bb; carbohydrate levels 31.51% bb; power of development of noodles 16.67%; color 2.5 (whitish yellow); aroma 3,9 (not typical flour); texture 2.5 (slightly springy); flavor 2,6 (rather umami); and preference level 2.8. The corn noodles still need to improve the process to reduce the high water content so that they have not fulfilled Indonesian Nasional Standard 01-2987-1992.
