Paragis is a common grass which is abundant and can be seen everywhere but is regarded as having no economic value. To add value to this grass, the study generally aimed to formulate cookies with powdered paragis leaves and mashed bananas; and specifically, it aimed to evaluate the sensory quality of the product. A 3 x 3 factorial design was used, with three levels for both powdered paragis leaves (0, 5, 10 % w/w) and mashed bananas (0, 15, 20 % w/w). Sensory evaluation was done to determine the product’s acceptability in terms of color, taste, aroma, texture, and flavor using a sensory panel. Acceptability ratings were subjected to response surface regression analysis using STATISTICA software. Results revealed that the combination of powdered paragis leaves and mashed bananas showed a significant effect on the color, aroma, texture, taste, flavor, and general acceptability of the product. The optimum combination was 8.8 % and 1.3 to 1.8% of mashed bananas and powdered paragis leaves, respectively, based on the volume of flour. It can be concluded that paragis leaves could be utilized in cookie production, providing potential value to this unwanted commodity using the optimum combination.

Purpose Due to the rise in urbanization, demand for easily prepared foods such as pastries and noodles has risen. But the high price of wheat in the global market puts financial stress on low-income people, especially on those living in tropical regions, where wheat does not thrive well. They depend solely on imported wheat, which is expensive due to importation cost, or seek other relatively less-nutritious cereals. Therefore the purpose of this paper is to investigate the possibility of supplementing wheat flour with flour from relatively cheap and easy-to-produce root tuber, such as cassava, potato and sweet potato. Design/methodology/approach Strong-, medium- and weak-gluten wheat flours were supplemented with flour from cassava, potato and sweet potato at 10, 20 and 30 percent. Strong gluten composites were used to make bread, whereas medium and weak gluten composites were used for cookie and noodle production, respectively. Protein, ash, fat, crude fiber, moisture, carbohydrate, gluten, zeleny and energy contents of each composite were tested. Findings The nutritional and sensory quality of bread, cookies and noodles made from wheat flour supplemented with root tuber flour at 10, 20 and 30 percent was assessed. Results revealed that mixing wheat flour and root tuber flour has important effects on the moisture, protein, carbohydrate, fat, ash, gluten, zeleny sedimentation value and crude fiber content of the resulting mixture. Moisture and carbohydrate increased while protein and fat significantly (p<0.05) decreased with increasing root tuber flour levels in formulations. Gluten content also decreased significantly with rising root tuber flour concentrations. There was a mild reduction in bread’s general acceptability at 10 and 20 percent in potato composites; thus potato flour was still acceptable at 20 percent. Cassava flour composite also topped with a general acceptability score of 69.26 at 20 percent in cookies, whereas sweet potato composite achieved a score of 84.81 in noodles. Originality/value This work has successfully confirmed that wheat flour could be supplemented up to 20 percent with root tuber flour without compromising the nutritional and sensory quality of products. It has also demonstrated that different products require different root tuber flour substitution for optimum results. Potato at 10 percent substitution was found to be best for bread production. Cassava and sweet potato at 10 percent substitution were also best for cookies and noodles, respectively. With respect to protein content only, sweet potato substitution is better than cassava and potato.

Yield and cob characteristics of 6 supersweet corn (Zea mays L.) cultivars, homozygous for the recessive shrunken-2 (sh2) allele, were compared at 3 separate planting dates, in 1987-88, at Bundaberg (lat. 25�S.), Queensland. Sensory quality of the 6 sh2 cultivars and a standard cultivar, homozygous for the recessive sugary (su) allele, were compared in a separate experiment. Marketable yield (total weight of cobs-in-husks with at least 125 mm usable kernels without damage or defects) declined between each of the plantings: midwinter, early spring, late spring. Marketable yield of the cultivar Sucro was consistently high (9.18-13.7 t/ha), whereas, that of Honey Sweet was low (2.88-5.43 t/ha). Total weight of unmarketable cobs (cobs-in-husks with 125 mm usable kernels or cobs-in-husks having at least 125 mm usable kernels, but with damage or defects) was highest for Honey Sweet and ranged between 5.31 and 9.18 t/ha. Marketable yields of the 6 sh2 cultivars were similar to those obtained in other warm climates but were lower than those in cooler climates. The cobs-in-husks of Honey Sweet and Sucro from the midwinter planting were marginally heavier than the preferred cob-in-husk range (310-360 g/cob) demanded on domestic markets; those of Snosweet, Candy Sweet and Florida Staysweet were within the range; and those of Sugar Sweet were significantly (P<0.05) lower. None of the cultivars at the 2 later sowing dates achieved this desirable weight range. Because of the higher yields and larger cobs produced in the midwinter planting, and the higher incidence of disease and heat stress encountered in the later plantings, it is proposed that sh2 cultivar production should be limited to a midwinter sowing in subtropical Bundaberg. Taste panel testing indicated preference for all sh2 cultivars over the standard su cultivar in terms of both general acceptability and texture (P<0.05), and the su cultivar was rated least sweet (P<0.05). Snosweet was rated highest in terms of both general acceptability and texture scores and was also rated the sweetest cultivar.

<p>The objective of this research was to study the effect of avocado pulp (A) and tomato paste (T) addition on the physicochemical, nutritional and sensory quality of pork frankfurters. Treatments were: 1) Control; 2) A10 = 10% A; 3) A20 = 20% A; 4) T10 = 10% T; 5) T20 = 20% T; and 6) A10+T10 = 10% A+10% T. Colour (<em>L*</em>, <em>a*</em> and <em>b*</em>), fatty acid profile, contents of phenols and flavonoids, and antioxidant capacity were measured. In the same way, sensory analysis was evaluated. Tomato paste decreased <em>L*</em> but increased (P &lt; 0.05) <em>a</em>* and <em>b</em>* values. On the other hand, A did not affect <em>L*</em>, decreased <em>a*</em> and increased <em>b*</em>. Avocado pulp increased (P &lt; 0.05) the proportion of monounsaturated fatty acids in the finished product. Antioxidant activity increased (P &lt; 0.05) with incorporation of T, much higher than that observed by adding A. Frankfurters with T and with a combination of T and A had the best acceptance by the sensory panel. The use of T and A can be a good strategy to improve nutritional quality and antioxidant properties of pork frankfurters.</p>

Continuously Cast

Free-cutting steel gains specific working properties thanks to the high content of sulfur and phosphorus. These elements, especially sulfur, have a rather high tendency to segregation. Therefore, segregation defects in free-cutting steel continuously cast billets can be significantly developed. The aim of the work was to study the influence of the chemical composition of freecutting steel and casting technological parameters on the quality of the macrostructure of continuously cast billets. A metallographic assessment of the internal structure of cast metal made of free-cutting steel and data processing by application of correlation and regression analysis were the research methods. The array of production data of 43 heats of free-cutting steel of grade A12 was studied. Steel casting on a five-strand radial type continuous casting machine was carried out by various methods of metal pouring from tundish into the molds. Metal of 19 heats was poured with an open stream, and 24 heats – by a closed stream through submerged nozzles with a vertical hole. High-quality billets had a cross-sectional size of 150×150 mm. The macrostructure of high-quality square billets made of free-cutting steel of A12 grade is characterized by the presence of central porosity, axial segregation and peripheral point contamination, the degree of development of which was in the range from 1.5 to 2.0 points, segregation cracks and strips – about 1.0 points. In the course of casting with an open stream, almost all of these defects are more developed comparing with the casting by a closed stream. As a result of correlation and regression analysis, linear dependences of the development degree of segregation cracks and strips both axial and angular on the sulfur content in steel and on the ratio of manganese content to sulfur content were established. The degree of these defects development increases with growing of sulfur content in steel of A12 grade. These defects had especially strong development when sulfur content in steel was of more than 0.10%. To improve the quality of cast metal, it is necessary to have the ratio of the manganese content to the sulfur content in the metal more than eight.

Perkembangan dunia perbankan syariah tidak lepas dari peran para nasabah yang memberikan kepercayaan terhadap pihak perbankan untuk penyimpanan asset keuangannya. Faktanya banyak kelompok nasabah yang memutuskan untuk menjadi nasabah di perbankan syariah karena faktor religiusitasnya. Faktor lain yang dapat ikut mempengaruhi keputusan nasabah adalah kualitas produk. Di mana kualitas produk merupakan karakteristik yang melekat dari suatu produk. Kemungkinan yang terjadi bahwa kebanyakan nasabah pada perbankan syariah juga masih merupakan nasabah perbankan konvensional.Tujuan yang ingin dicapai dalam penelitian ini adalah untuk mengetahui pengaruh kualitas produk dan tingkat religiusitas nasabah terhadap keputusan nasabah untuk menyimpan dananya atau tidak di BSM Cabang Purwokerto. Alat analisis yang digunakan adalah analisis regresi linier berganda, dengan jumlah sampel 100 nasabah. Diperoleh hasil Y = 5,046 + 0,101X1 + 0,218X2. Berdasarkan uji F yang sudah dilakukan maka dapat diketahui bahwa variabel kualitas produk dan religiusitas secara bersama – sama berpengaruh terhadap keputusan nasabah untuk menyimpan dananya di BSM Cabang Purwokerto. Berdasarkan uji t yang sudah dilakukan dapat diketahui bahwa secara partial baik variabel kualitas produk maupun variabel religiusitas berpengaruh terhadap keputusan nasabah untuk menyimpan dananya di BSM Cabang Purwokerto. The progress of the Islamic bank cannot be separated from the role of its customers who give trust to the bank to deposit their financial assets. It is a fact many groups of customers decide to be the customers of the Islamic bank because of their religiosity. The other influences factor of a customer’s decision is the quality of the product. The aim of this research was to determine the effect of product quality and level of customers’ religiosity towards customers’ decision whether to keep their funds in Syariah Mandiri Bank, Branch of Purwokerto, or not. The analytical tool used was multiple linear regression analysis, with a sample of 100 customers. The results indicate Y = 5,046 + 0,101X1 + 0,218X2. Based on F, it can be seen that both variables of product quality and religiosity simultanously affect the customers’ decision to keep theirfunds in BSM Branch of Purwokerto. Based on t test, it can be seen that independently, either variable of product quality or variables of religiosityinfluences the customers’ decision to keep their funds in BSM Branch of Purwokerto.
