Abstract

ABSTRACT Kembang goyang snack is a traditional Indonesian food with a crunchy texture. The main ingredient for this snack is rice flour. Utilization of soybean waste flour formulated with rice flour in kembang goyang snack will increase the nutritional value however, it will decrease the crispness. The purpose of this study was to determine the effect of different formulations of rice flour and soybean waste flour (100:0, 90:10, 80:20, 70:30, and 60:40) on the quality of the kembang goyang snack. The quality of the cakes consists of physical quality (crisp), chemical (moisture content, ash content, protein content, fat content, carbohydrate content, crude fiber content), and organoleptic (color, aroma, taste, and texture). This study used an experimental method with a single factor Completely Randomized Design (CRD) with five levels. Each level consisted of 3 replications. The data will be analyzed by analysis of variance (ANOVA) and further test with Duncan’s test if the results of the ANOVA test are significant. The results showed that the different formulations of rice flour and soybean waste flour affected the physical, chemical, and organoleptic qualities (α=0.01). The more formulations of soybean waste flour used, the water, ash, protein, fat, crude fiber, and unpleasant aroma content will increase, while the crispness, carbohydrate content, color, taste, and texture will decrease. The acceptable formulations of rice flour and soybean waste flour in kembang goyang snack are 80:20, with 11.37 g/mm2 crispness, 2.51% water content, 1.02% ash, 8.43% protein, 24.23% fat, 63.81% carbohydrates, 3.60% crude fiber and 8.35% dietary fiber as well as an organoleptic quality which includes brownish yellow color, not strong soybean aroma, slightly sweet and savory taste, and crispness texture. The moisture content of the kembang goyang snack complies with Indonesian National Standard for rice crackers SNI 01-4307-1996.   ABSTRAK Kembang goyang adalah kue tradisional Indonesia dengan tekstur renyah. Bahan utama kue kembang goyang adalah tepung beras. Pemanfaatan tepung ampas kedelai yang diformulasikan dengan tepung beras pada kue kembang goyang akan meningkatkan nilai gizi, tetapi akan menurunkan kerenyahannya. Tujuan dari penelitian ini untuk mengetahui pengaruh formulasi tepung beras dan tepung ampas kedelai yang berbeda (100:0, 90:10, 80:20, 70:30, dan 60:40) terhadap mutu kue kembang goyang. Mutu kue kembang goyang terdiri dari mutu fisik (kerenyahan), kimia (kadar air, kadar abu, kadar protein, kadar lemak, kadar karbohidrat, kadar serat kasar) dan organoleptik (warna, aroma, rasa dan tekstur). Penelitian ini menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL) faktor tunggal dengan lima taraf. Masing-masing taraf terdiri dari 3 ulangan. Data akan dianalisa dengan analisis varian (ANAVA) dan uji lanjut dengan DMRT, bila hasil uji ANAVA signifikan. Hasil penelitian menyatakan bahwa formulasi tepung beras dan tepung ampas kedelai yang berbeda memengaruhi mutu fisik, kimia dan organoleptik (α=0.01). Semakin banyak formulasi tepung ampas kedelai yang digunakan maka kadar air, abu, protein, lemak, serat kasar, dan aroma langu akan semakin meningkat, sedangkan kerenyahan, kadar karbohidrat, warna, rasa, dan tekstur semakin menurun. Formulasi tepung beras dan tepung ampas kedelai pada kue kembang goyang yang masih dapat diterima adalah 80:20, dengan kerenyahan 11.37 g/mm2, kadar air 2.51%, abu 1.02%, protein 8.43%, lemak 24.23%, karbohidrat 63.81%, serat kasar 3.6% dan serat pangan 8.35% serta mutu organoleptik yang meliputi warna kuning kecoklatan, aroma langu kedelai tidak kuat, rasa agak manis dan gurih, serta tekstur renyah. Kadar air kue kembang goyang memenuhi Standar Nasional Indonesia kerupuk beras SNI 01-4307-1996.

ABSTRACT The glucomannan in iles-iles tubers needs to continuously develop the production procedures to increase the economic value of tubers, which are export commodities with a high level of demand. This study aimed to determine the effectiveness of increasing the α-amylase concentration on glucomannan levels, degree of whiteness (DoW), and their interactions. The method was modified to increase α-amylase concentration (2.5, 4.5, 6.5, and 8.5 % (v/v)) in 3 Litter of Water with a mixture of 100 grams of iles-iles flour. Meanwhile, the determination of DoW analyzed was used chromameter. The results showed that the best treatment was the α-amylase concentration of 2.5% (v/v) in 2 hours resulting in the highest glucomannan content compared to other concentrations. Based on the results of analysis of variance (ANOVA), it showed that the interaction between time and concentration and treatment time (2, 4, and 6 hours) and concentration (2.5, 4.5, 6.5, and 8.5% (v/v)) had a significant effect on glucomannan levels. However, the level of DoW was still experiencing an enlargement result compared with DoW of commercial glucomannan flour.   ABSTRAK             Glukomanan dalam umbi iles-iles perlu terus dilakukan pengembangan prosedur produksi untuk meningkatkan nilai ekonomis umbi yang merupakan komoditas ekspor dengan tingkat permintaan tinggi. Penelitian ini bertujuan untuk mengetahui efektifitas peningkatan konsentrasi enzim α-amilase terhadap kadar glukomanan, derajat putih dan interaksinya. Metode yang dilakukan merupakan metode modifikasi peningkatan konsentrasi enzim α-amilase 2.5, 4.5, 6.5 dan 8.5 % (v/v) dalam 3 L air dengan campuran 100 gr tepung iles-iles. Sedangkan penentuan derajat putih dianalisis dengan alat chromameter. Hasil menunjukkan bahwa perlakuan terbaik didapatkan dengan konsentrasi enzim α-amilase 2.5% dengan waktu 2 jam menghasilkan kadar glukomanan tertinggi dibandingkan dengan kadar glukomanan perlakuan lainnya. Berdasarkan hasil analisis variansi (ANOVA) memperlihatkan interaksi antara waktu dan konsentrasi serta perlakuan waktu (2, 4, dan 6 jam) dan konsentrasi (2.5, 4.5, 6.5, dan 8.5 %) berpengaruh nyata terhadap kadar glukomanan. Akan tetapi tingkat keputihan masih mengalami pelebaran hasil dengan derajat keputihan tepung glukomanan komersial.

Abstract

ABSTRACT Secang (Caesalpinia sappan) is known as a red coloring agent in histological staining. One of the active components found in Secang is the brazilin compound. These compounds are reported to have biological activities such as hypoglycemic and antioxidants. The formation of resistant starch in traditional food processing such as secang rice as an effort to reduce blood glucose levels has never been reported. The aims of this study were to determine the total phenolic and antioxidant activity of secang wood extract in the manufacture of secang rice, and to determine the levels of resistant starch of secang rice with different concentrations of addition of secang wood extract. This research was conducted using 4 treatments of secang wood extract, control (without secang wood extract), 5 mL, 7.5 mL, and 10 mL of secang wood extract. The parameters analyzed were total phenolic, antioxidant activity (DPPH) in secang extract and secang rice, and content of resistant starch in secang rice. The results showed that the total phenolic extract of secang wood was 3524.03 ± 20.42 mg GAE / 100 g of the sample and the percent inhibition of free radicals was 94.01 ± 1.76%. The higher the addition of secang wood extract to 10 mL is, the higher the total phenolic and percent free radical inhibition in secang rice. The highest total phenolic and percent free radical inhibition was found in rice which was added with 10 mL of secang extract, i.e. 13.75 ± 0.96 mg GAE / sample and 75.77 ± 0.77%, and the highest resistant starch content was 1.6 ± 0.24%.   ABSTRAK             Secang (Caesalpinia sappan) dikenal sebagai bahan pewarna merah dalam pewarnaan histologi. Salah satu komponen aktif yang terdapat pada secang adalah senyawa brazilin. Senyawa ini dilaporkan memiliki aktivitas biologi seperti hipoglikemik dan antioksidan.
