Egg roll merupakan sejenis makanan ringan yang banyak disukai oleh anak-anak sampai dewasa, memiliki rasa manis dan gurih, dengan tekstur yang renyah, dan berbentuk gulungan utuh. Umumnya egg roll yang terbuat dari tepung terigu memiliki tekstur yang mudah rapuh, sehingga untuk mengurangi tingkat kerapuhannya dapat dilakukan dengan menambahkan tepung terigu dengan ppati pada formula egg roll. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan pati sagu terhadap karakteristik egg roll dan menentukan formulasi terbaik egg roll berbasis pati sagu.. Penelitian ini menggunakan rancangan acak lengkap faktor tunggal dengan 5 formulasi variasi perbandingan tepung terigu dan pati sagu. Produk egg roll yang dihasilkan dari kelima formulasi tersebut dilakukan analisa warna, tekstur, organoleptikc dan komposisi kimianya. Makin tinggi konsentrasi pati sagu maka egg roll menjadi berwarna kemerahan, kekerasan dan kerenyahan menjadi menurun, namun tekstur egg roll menjadi tidak rapuh. Semakin tinggi konsentrasi pati sagu, maka kadar air, karbohidrat dan pati resisten egg roll semakin meningkat namun kadar lemak dan protein egg roll semakin menurun. Perlakuan terbaik diperoleh dari formula 100% pati sagu dengan karakteristik fisik egg roll yang dihasilkan yaitu nilai kekerasan 21,96 N, kerenyahan 31,52 Nmm, dan kerapuhan 4,90 N, serta komposisi kimia egg roll yaitu kadar air 4,73%, kadar protein 7,87%, kadar karbohidrat 56,77%, kadar abu 1,42%, kadar lemak 33,94% dan RS (resistant starch) 0,98%. Egg roll berbasis pati sagu dapat diterima oleh panelis dengan nilai terhadap atribut keseluruhan tertinggi yaitu 6,03. Kesimpulannya, pati sagu dapat digunakan dalam formula pembuatan egg roll. Physicochemical and Sensory Properties of Egg roll BasedSago StarchAbstractEgg roll is a snack which were favored by children and adults, it has a sweet and savory taste, with a crunchy texture, and in the form of whole rolls. Generally, egg roll made from wheat flour which has brittle texture, and to reduce its fragility, starch addition in egg roll formula may be applied. The purpose of this study was to determine the effect of sago starch addition to egg roll formula on the characteristics of egg roll and determine the best formula. This study used a single randomized complete design with 5 formula using various ratio of wheat flour and sago starch. Egg roll products were analyzed for color, texture, organoleptic, and chemical composition. The higher the concentration of sago starch, the reddish egg roll, hardness that was appeared and the decrease in crispness was detected, and resulting in the reduction in the brittleness. The higher the concentration of sago starch might increase the water content, carbohydrate and resistant starch of egg roll but the not for fat content and protein. The best treatment was the formula with 100% sago starch with the physical characteristics of the egg roll produced with the hardness value of 21.96 N, crispness of 31.52 Nmm, fragility of 4.90 N, water content of 4.73%, protein content of 7.87%, carbohydrate content of 56.77%, ash content of 1.42%, fat content of 33.94% and RS (resistant starch) of 0.98%. Egg roll based sago starch could be accepted by panelists with the highest overall attribute value of 6.03. As conclusion, sago starch might able to apply in the production of egg role.

Adlay is a nutritious grain that has the potential as an alternative food because it has a high protein and fat content of 14.10% and 7.90%, respectively. The use of Adlay as flour still has a weakness, namely the functional properties of Adlay flour such as low swelling power. One way to improve the characteristics of Adlay flour is by fermentation using Rhizopus oligosporus. The fermentation duration is the time that allows changes in the characteristics of the flour due to the fermentation. This study aims to determine the effect of differences in fermentation duration using Rhizopus oligosporus on the physical, chemical, and functional characteristics of Adlay flour produced from fermented Adlay seeds. This study used one factor, namely the lengths of fermentation for 0, 12, 24, 30, 36 and 48 hours. The analysis in this study included whiteness, yield, pH, water content, ash content, protein content, fat content, carbohydrate content, swelling power and solubility, oil holding capacity (OHC) and water holding capacity (WHC). The results have shown that the longer the fermentation duration the lower rate of whiteness, pH, yield, water content, fat content, and carbohydrate content will become, while some functional properties of Adlay flour become better with increasing values of ash content, protein content, swelling power, solubility, Oil Holding Capacity (OHC), and Water Holding Capacity (WHC).

This study aims to determine the difference of characteristic and starch digestibility of germinated and ungerminated flour. This study used randomized complete design (RCD) three repeated. The corn germinated for 36 hours. Corn germinated flour and ungerminated flour were evaluated directly of the chemical composition of the flour content, moisture content, ash content, protein, fat, carbohydrates, fiber, starch content and starch digestibility. The results showed the corn germinated flour has increased of moisture content from 9.66% into 10.38%, increased of protein into 7.22% into 8.45%, increased of fiber content from 2.28% into 2.79% and increased of starch digestibility from 57.04% into 62.43%. While were the decreased fat content from 5.17% into 4.76%, decreased of carbohydrate from 75.41% into 73.89% and decreased of starch content from 76.10% into 69.40%. The treatmented has no effect for the flour content decreased from 41.40% into 40.36% and ash content decreased from 2.52% into 2.51%. Germinated increased starch digestibility and changed the character of corn flour.
