Bolu steamed is one of the cakes that is enough to be contaminated by the community. The basic ingredient is wheat flour. Excessive use of wheat flour can interfere with the health of small bowel damage, so it is necessary to do substitution efforts with other flour such as cassava flour and green bean flour. Using cassava as the basic ingredient of steamed cakes is an alternative to adding nutrients. But the cassava is low in protein, so it is necessary to increase the source of proteins. Green beans have a fairly high protein content. Therefore, it is necessary to review the influence of the addition of green bean flour in steamed cakes made from cassava flour. The results showed the cassava flour affects the level of delight in the colour and flavor of the steamed bolu, while the addition of green bean flour is influential against the color, texture and flavor but does not affect the aroma of the steamed bolu. Based on proximate testing, moisture content of ash, protein levels, fat content and carbohydrate levels contained in the steamed Bolu does not exceed the standard based on the wet cake SNI, while the moisture content of the steamed Bolu exceeds the standards that can be influential On the shelf power of steamed cakes.
ABSTRACT Sweet potato is a plant that is easy to be cultivated and very potential to be processed into flour. But the quality is still low compared to other flour especially when heated. Because it is done to improve the quality especially when heated. Modification done crosslink using sodium tripolyphosphate reagent (STPP). The purpose of this study was to determine the effect of modified flour on flour characteristics when heated. Parameters used in this research are water absorption, Swelling Power, and flour solubility. The data processing used is RAL of 1 factor at the 0.05 level and further test using Duncan test. The results showed that the characteristics of flour modification is better than natural flour. The higher the concentration of STPP used, the water absorbency increases, the swelling power increases, and solubility decreases. Sweet potato flour has optimum absorption limit and optimal development on reaction process for 1 hour, and will decrease at longer reaction process.. Key words: sweet potato, sweet potato flour, modified flour, crosslink modification, STPP ABSTRAK Ubi jalar merupakan tanaman yang mudah dibudidayakan dan berpotensi diolah menjadi tepung, namun kualitasnya masih rendah dibandingkan dengan tepung lainnya, khususnya saat dipanaskan. Oleh karena itu, perlu dilakukan upaya meningkatkan kualitas tepung ubi jalar terutama saat dipanaskan. Modifikasi dilakukan secara crosslink dengan pereaksi sodium tripolyfosfat (STPP). Tujuan penelitian ini adalah menentukan pengaruh modifikasi terhadap karakteristik tepung saat dipanaskan. Parameter yang digunakan pada penelitian ini adalah daya serap air, swelling power, dan solubillitas tepung. Pengolahan data menggunakan RAL faktorial pada taraf 0,05 dan uji lanjut menggunakan uji Duncan. Hasil penelitian menunjukan bahwa karateristik tepung modifikasi lebih baik daripada tepung alami. Semakin tinggi konsentrasi STPP, daya serap air meningkat, nilai swelling power meningkat, dan solubilitas menurun. Tepung ubi jalar memiliki batas optimum penyerapan serta pengembangan optimal pada reaksi selama 1 jam dengan konsenrasi STTP 3%, serta menurun pada reaksi yang lebih lama.

The study aimed to determine the oil content and identify fatty acid methyl esters such as stearate, palmitate, linolenate, linoleate, and oleate in seeds and nuts like candlenut, peanut, sesame, sunflower, and sacha inchi. Oil extraction was carried out using Soxtec 8000 TM and n-hexane solvent. The samples were dried at 50 o C. The extraction conditions optimized were temperature 135 o C, n-hexane 50 mL, boiling time 40 min, and total extraction time 115 min. Identification of fatty acids was carried out using Attenuated Total Reflection (ATR), Nuclear Magnetic Resonance (NMR), and Gas Chromatography-Flames Ionization Detector (GC-FID). The oil percentage detected in each sample was candlenut (59.95%), peanut (40.08%), sesame (57.06%), sunflower (43.97%), and sacha inchi (51.71). The ATR results show that the flour of nuts and seeds has a strong vibrational frequency of the O−H molecule. Linolenate was detected at a chemical shift of 0.975 ppm in NMR spectra and was found in sacha inchi and candlenut. The ATR, NMR, and GC-FID results showed that all samples contained unsaturated fatty acids. Candlenut, peanut, sesame, and sacha inchi were rich in linoleate (ω-6) as much as 25.68%, 20.15%, 26.38%, and 20.73%, respectively. Oleate was abundant in sesame (21.87%) and sunflower (16.78%). Linolenate was found only in sacha inchi (22.88%). The maximum percentage of stearate was found in sunflower (4.02%) followed by sesame (2.96%), candlenut (1.81%), sacha inchi (1.52%), and peanut (0.71%). This research provides useful information on fatty acid profiles beneficial for health, especially stearic acid, which can substitute trans fatty acids harmful to health.
Edible film berbahan dasar tebung jagung putih dimodifikasi dengan karagianan dan gliserol. Gel dari karagenan dapat meningkatkan kekuatan dan homogenitas suspensi edible film. Sementara gliserol dapat meningkatkan permeabilitas film, selain itu menjadikan film lebih halus dan tidak mudah retak. Tujuan penelitian antara lain mengetahui Kualitas edible film dari tepung jagung putih diketahui dengan cara: karakterisasi dan uji proksimat tepung jagung sebagai bahan baku, analisis sifat fisik dan mekanik edible film, optimasi konsentrasi optimal gliserol dan karagenan. Optimasi konsentrasi dilakukan dengan melakuakan variasi konsentrasi gliserol (5%, 10%, dan 15%) dan konsentrasi karagenan (1%, 2% dan 3%). Karaktistik dan kualitas tepung jagung putih dari Kabupaten Sumbawa menggunakan FTIR dan uji proksimat serta uji warna. Spektra IR menunjukkan bahwa tepung jagung Sumbawa tersusun dari gugus fungsi alkana, alkohol, keton/aldehid, hemiaketal dan hemiasetal yang merupakan gugus fungsi dari molekul karbohidrat. Sementara hasil uji proksimat menunjukkan bahwa tepung jagung Sumbawa memiliki kadar air, abu, lemak, protein, karbohidrat, amilosa, amilopektin serta pati berurut – turut: 12,61%; 0,72%; 0,08% ;0,41% ;86,17% ;55,40%; 19,84% ;77,30%. Hasil uji warna tepung jagung menunjukkan bahwa tepung jagung tanpa perlakukan memiliki warna putih tulang dan gelap, sehingga dalam penggunaanya sebagai bahan edile film perlu dimodifikasi dengan cara perendaman dalam natrium metabisulfit kemudian difermentasi untuk mengurangi kadar asam fitat yang bersifat antinutrisi dalam tepung jagung. Sifat fisik dan mekanik dari edible film berbahan dasar tepung jagung putih diketahui menggunakan uji warna, kuat tarik dan persen pemanjangan film didukung oleh FTIR. Hasil FTIR menunjukkan pengaruh gliserol dan karagenan terlihat dari vibrasi ikatan O–H (3400-3300 cm-1), vibrasi ikatan CH2 (1465 ) overlap dengan vibrasi ikatan S–O, S═O pada karagenan, vibrasi ikatan C–O, C═O (1600 cm-1, 1200-1020 cm-1) yang terlihat pada spektra IR edibe film G5%K2%. Konsentrasi optimal gliserol dan karagenan dalam pembuatan edible film tepung jagung putih yakni: gliserol 5-10% dan karagenan 3% sebab memiliki elongasi dan kuat tarik optimum serta warna edible film yang cerah. Elongasi dan kuat tarik optimum berturut - turut : 40 – 43.33%; 2,4 – 3,6 N. Hasil uji warna sampel edible film dengan kandungan gliserol 5-10% dan karagenan 3% menunjukkan index keputihan 54-58.
The Averrhoa Blimbi L. is spread all over in Indonesia as home garden plant. It has not been yet cultivated and developed its utilization. The utilization of this Averrhoa Blimbi L. that can be attempted is that as an instant powder. This fruit contains of chemical elements functioning as natural antioxidant. This study attempts to investigate the variation concentration of Averrhoa Blimbi L. extract on antioxidant activity by using DPPH (1, 1-difenil-2-pikrilhidrazil) method and UV-Vis spectrophotometer. Based on the result of the antioxidant activity test, it is found that different treatment shows different antioxidant activity. At concentration of Averrhoa Blimbi L.: sugar, Y1 (1:1) is -7.8%, Y2 (2:1) is -3.4%, and Y3 (4:1) is 48.4%. This indicates that the more the extract of Averrhoa Blimbi L. is added, the higher antioxidant activity is. The organoleptic test in this study includes colour, aroma, texture, and taste. The most preferred treatment is Y3 (Averrhoa Blimbi L.: sugar: = 4:1). The level of panelist acceptance score on the test parameter is shown as follows: the colour is 2.34 (bright yellow), the aroma is 2.45 (a little bit of sour aroma), the texture is 2.21 (smooth), and the taste is 2.15 (sweet and a bit of sour).
