The antioxidant activity of cookies prepared by the addition of sugarbeet dietary fibers was investigated in order to estimate their influence on functional characteristics and shelf-life of cookies. Treated fiber (TF) was obtained from sugarbeet by extraction with sulfurous acid (75 °C at pH = 5.7during 60 min) and treatment with hydrogen peroxide (20 g/LH2O2 at pH = 11 during 24 h). The fiber obtained was dried (80 °C), ground and sieved. TF was investigated in comparison with commercially available Fibrex®. The cookies were prepared by the addition of 0, 7, 9 and 11% of sugarbeet dietary fiber as a substitute for wheat flour in the formulation of cookies. The antioxidant properties of cookies were tested every 7 days using a DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity test during 6 weeks of storage at room temperature (23 ± 1 ºC). The obtained results indicated that substitution of wheat flour with Fibrex® in the formulation of cookies upgraded the antioxidant activity, i.e. the functional characteristics of Fibrex®-enriched cookies and could prolong their shelf-life. In contrast, TF did not increase the antioxidant activity of TF-enriched cookies. The better antioxidant activities of Fibrex®-enriched cookies could be attributed to the presence of ferulic acid.

Sugar beet pulp (SBP) is a by-product of the sugar industry in which the dietary fiber content ranges from 73% to 80%. Compared to cereal fibers mainly used in biscuit production, sugar beet fibers are gluten free and have a perfect ratio of 2/3 insoluble fiber. In this work, sugar beet pulp was extruded with corn grits (ratios of corn grits to sugar beet pulp in extrudates were 85:15, 70:30, and 55:45), and the obtained sugar beet pulp extrudates (SBPEs) were used for improving the nutritional quality of cookies. The wheat flour in cookies was replaced with SBPEs in the amount of 5, 10, and 15%. The influence of three factors (the percentage of sugar beet pulp in the SBPEs, the size of the SBPE particles, and the percentage of wheat flour substituted with SBPEs) and their interactions on the nutritional quality of cookies, as well as their physical and sensory characteristics are examined using the Box–Behnken experimental design. The addition of extruded sugar beet pulp (SBPEs) significantly increased the amount of total dietary fiber and mineral matter of cookies. On the whole, the addition of SBPEs increased cookie hardness, but the hardness decreased with an increase in extrudate particle size. Sensory characteristics (except for the taste) were the most influenced by extrudate particle size.

Effects of different levels of wheat flour as dietary fiber on the quality of fresh and preserved beef meatballs during storage were explored in this study. Ground beef (Batter) samples were divided into four treatment groups and treated with different level of wheat flour as T1 (control, 0%), T2 (5%), T3 (10%) and T4 (15%). Proximate analysis (dry matter, ash, ether extract and crude fat), sensory tests (color, flavor, tenderness, juiciness, overall acceptability), biochemical analysis (free fatty acids, Thiobarbutiric acid values and peroxide value) and microbiological examination were carried out as responses at the interval of 0, 30 and 60 days during storage at -200C. The experimental design was a 4 × 3 factorial in Completely Randomized Design replicated three times per cell. DM content was increased significantly (p<0.05) with the advancement of storage intervals. CP and EE content of all the treatments were decreased significantly (p<0.05) among the different treatment groups. FFA and TBARs values were differed significantly (p<0.05) at different treatment levels. PVs were decreased significantly (p<0.05) at different treatment levels. Color, cooking loss and overall acceptability were differed significantly (p<0.05) at different treatment levels. Raw and cooked pH were increased significantly (p<0.05) at different treatment levels. The juiciness at different treatment levels were decreased significantly(p<0.05).TVC (logCFU/g), TCC (logCFU/g) and TYMC (logCFU/g) were differed significantly (p<0.05) at different treatment levels. In conclusions, meatballs having 5% wheat flour was better in terms of color, odor, tenderness, juiciness and overall acceptability, cooking loss and microbial qualities.Bang. J. Anim.

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. Kata Kunci: crackers, pisang tongka langit

Owing to the concept of modern life and health, traditional baked foods are seeking transition. In this study, sweet corn residue (SCR) was used to replace wheat flour in cakes. We conducted sensory evaluation and texture analysis to assess sample quality. Also, we simulated digestion in vitro, and determined the content of total sugar and dietary fiber. The content of vitamin E and carotenoids were determined by High Performance Liquid Chromatography (HPLC), and the content of folate was determined by a microbiological method. With the increase of SCR, the content of dietary fiber, folate, vitamin E, and carotenoids significantly increased, and the digestive characteristics improved simultaneously. Based on the above evaluations, SCRC2 (sweet corn residue cake with 60% substitution) had similar sensory quality to the control (pure wheat flour cake) and had the characteristics of slow digestibility and high micronutrients.
