Rapid visible–near infrared (Vis–NIR) spectroscopic detection and quantification of unripe banana flour adulteration with wheat flour

ABSTRACT Cake is made from wheat flour, sugar, and eggs. The supply of wheat flour depends on wheat import. The wheat imports predicted to continue to increase, so it is necessary to find an alternative to reduce the use of wheat flour as a primary ingredient of cake sourced from local raw materials which low utilized. Balbisiana banana was a low class of banana which had a low optimal utilization because it was disliked by the people. Balbisiana banana had a dark lightness so it was needed to add the yellow sweet potato flour to increase the brightness of the cake. Balbisiana banana and yellow sweet potato flour could be used as wheat to substitution because had high starch content, good nutritional value and low IG value. The purpose of this research was to know the influence of the proportion of balbisiana banana and yellow sweet potato flour on the physical and organoleptic characteristics of cake, to know the proportion of balbisiana banana and yellow sweet potato flour on cake with good properties and high preference, and chemical properties of cake high preference. The results showed that the proportion of balbisiana banana and yellow sweet potato flour significantly affected on color (lightness), loaf volume, and staleness, and there were difference on preference of color, flavor and overall but not difference taste and staleness (p <0.05). Cakes with good properties and high preference were P5 (10% balbisiana banana flour: 40% yellow sweet potato flour) and P6 (50% yellow sweet potato flour). This cake had moisture content 26,21% - 27,58%, ash content 1,19% - 1,26%, fat content 20,42% - 21,23%, protein content 11,45% - 11,74%, and carbohydrate content 38,26% - 40,65%. Keywords: balbisiana banana flour, yellow sweet potato, cake ABSTRAK Cake adalah kue berbahan dasar terigu, gula, dan telur. Ketersediaan terigu tergantung pada hasil impor gandum. Impor terigu diprediksi akan terus mengalami peningkatan, sehingga perlu dicari alternatif untuk mengurangi penggunaan terigu sebagai bahan dasar cake yang bersumber dari bahan baku lokal yang belum termanfaatkan secara optimal. Pisang batu termasuk pisang kelas rendah yang pemanfaatannya kurang optimal karena kurang disukai. Tepung pisang batu memiliki warna cenderung gelap sehingga perlu penambahan tepung ubi jalar kuning untuk meningkatkan kecerahan warna cake. Tepung pisang batu dan ubi jalar kuning dapat digunakan sebagai bahan substitusi terigu karena adanya kandungan pati yang tinggi, memiliki nilai nutrisi yang baik dan juga memiliki nilai IG yang rendah. Tujuan dari penelitian ini adalah mengetahui pengaruh proporsi tepung pisang batu dan tepung ubi jalar kuning terhadap karakteristik fisik dan organoleptik cake, mengetahui proporsi dengan tepung pisang batu dan tepung ubi jalar kuning pada cake dengan sifat-sifat yang masih baik dan disukai, serta kandungan kimia cake perlakuan yang masih baik. Hasil penelitian menunjukkan bahwa proporsi tepung pisang batu dan tepung ubi jalar kuning berpengaruh nyata terhadap warna (lightness), daya kembang, dan staleness, serta terdapat perbedaan tingkat penerimaan panelis terhadap parameter warna, aroma dan keseluruhan namun tidak terdapat perbedaan tingkat penerimaan panelis terhadap parameter rasa dan tekstur (p<0,05). Cake dengan sifat-sifat yang masih baik dan disukai terdapat pada proporsi P5 (10% tepung pisang batu: 40% tepung ubi jalar kuning) dan P6 (50% tepung ubi jalar kuning). Karakteristik kimia cake yang masih baik mengandung kadar air 26,21% - 27,58%, kadar abu 1,19% - 1,26%, kadar lemak 20,42% - 21,23%, kadar protein 11,45% - 11,74%, dan kadar karbohidrat 38,26% - 40,65%.

Tongka langit banana contain high nutrients including pro vitamin A and a total of carotene. However, it is also a perishable product, and would deteriorate if not processed or not completely consumed. Therefore, this banana should be processed into diverse products. It can be processed into intermediate product such as flour, which can be further applied in crackers making. This research was conducted in two stages. First stage was the making of tongka langit banana flour and the second was crackers making. The crackers were made from tongka langit banana flour and wheat flour having different ratios, i.e. 20 %: 80 %; 40 %: 60 %; 60 %: 40 %; 80 %: 20 %. Variables observed on crackers including moisture, ash, protein, fat, dietary fiber and carbohydrate contents, as well as organoleptic properties of taste, aroma, colour, texture and overall likeness. Results showed that ratio of banana flour to wheat flour of 40%:60% produced crackers with moisture, ash, protein, fat, fiber, and carbohydrate contents of 4.60%, 4.46%, 6.64%, 17.54%, 1.18% and 4.60%, respectively. In addition, organoleptic test revealed that crackers made from 40% banana flour and 60% wheat flour were mostly liked by panelists in terms of taste, colour, aroma, texture and overall likeness. Keywords: crackers, tongka langit banana ABSTRAK Pisang tongka langit kaya akan kandungan gizi antara lain mengandung provitamin A dan total karotenoid yang sangat tinggi. Namun pisang tongka langit mudah mengalami kerusakan jika tertunda pengolahannya atau tidak habis dikonsumsi, oleh karena itu perlu dilakukan upaya diversifikasi terhadap pisang tongka langit. Pisang tongka langit dapat diolah menjadi bahan setengah jadi berupa tepung yang dapat diaplikasikan menjadi produk crackers. Penelitian ini dilakukan dalam dua tahap, tahap I adalah pembuatan tepung pisang tongka langit dan tahap II adalah pembuatan crackers dari tepung pisang tongka langit dan tepung terigu dengan empat taraf perlakuan perbandingan subtitusi tepung pisang tongka langit dan tepung terigu yaitu masing-masing 20 %: 80 %; 40 %: 60 %; 60 %: 40 %; 80 %: 20 %. Pengamatan yang dilakukan pada crackers yaitu analisa kadar air, abu, protein, lemak, serat pangan, karbohidrat dan uji organoleptik yang meliputi rasa, aroma, warna, tekstur dan tingkat kesukaan secara keseluruhan. Hasil penelitian menunjukkan bahwa formula crackers tepung pisang tongka langit 40% : 60% memiliki nilai kadar air berkisar antara 4,60%, kadar abu 4,46%, protein 6,64%, lemak 17,54%, serat 1,18% dan karbohidrat 4,60%. Sedangkan uji organoleptik menunjukkan bahwa crackers tepung pisang tongka langit 40% : tepung terigu 60% memiliki rasa, warna, aroma, tekstur dan tingkat penerimaan secara keseluruhan yang disukai panelis.

The objective of this study was to compare the compositional and functional properties of tropical flour sources (two breadfruit flours (type A and type B) and a banana flour) with a more traditional flour source (wheat flour). Macro-nutrient composition, pH, water and oil holding capacity, bulk density, particle size, solubility, swelling power, pasting properties, and thermodynamics (gelatinization and retrogradation) were determined. All flours evaluated were similar in their composition with high levels of carbohydrates (greater than 82.52 g/100 g on a dry-matter basis), with most of the carbohydrate content comprised of starch (greater than 67.02 g/100 g). The tropical fruit flours had greater (p < 0.05) water holding capacity than wheat flour. Breadfruit flour B had the lowest (p < 0.05) bulk density, while banana flour had the greatest (p < 0.05) bulk density. The swelling power of the tropical flours was greater (p < 0.05) than the wheat flour. The viscosity of the tropical flours was higher than wheat flour but decreased significantly when temperature was held at 130 °C. These results indicated that the two breadfruit flours and banana flour have great potential for application in processed food products, and have similar compositional attributes to a more traditional flour.
