These biscuits are made with “strong” flour, which has a high protein content, typically 10-12%. Therefore, the chosen final treatment was prepared with 20% added WG. The sensory characteristics of the two prepared biscuits blends (with 20% added wheat germ and control without added wheat germ) after baking and storage for two months at room temperature were assessed by 25 panelists chosen from the teaching staff, graduated students and technicians of the Department of Nutrition and Food Technology, Al-Huson University College. This could be due to increasing fiber content of biscuit by addition of WG that modified these two parameters. Ruchika Mehra, Kalyan Srinivasan, in Comprehensive Handbook of Iodine, 2009. Key: — • —, color; —, thickness; • • •, weight. Thus, liquid oils are normally excluded from blends, except for some specialized ‘health’ biscuits. While water is also added to a biscuit, cookie, or cracker dough, this is not a major component of the final product since it evaporates during baking. The major producers receive blends in road tankers at temperatures several degrees above the complete melting point, store in suitable tanks, and subsequently chill and texturize as required. There must be generally less than 5% solid triacylglycerols at 35 °C and 0.5% maximum at 40 °C. level of wheat germ, that can be added to one The panelists were from both sexes, and from different ages, they were requested to taste each sample separately without comparing it with another sample. A decrease of the specific volume and density and an increase in the hardness were noticed with increasing the levels of date powders It, amongst many snack items, has certain advantages, such as being cheaper than the conventional snack items, easy to use at home or even during travel, easily being available in massive variety of shapes, sizes, tastes, and packs, and appeals to all age groups. This increment in protein and total minerals as well as decrement in fat and total carbohydrates is beneficial from nutritional point of view, since it increases the quantity and quality of amino acids and minerals, while decreases the total calories that acquired from this product. Biscuits, cookies, and crackers are enjoyed the world over by consumers who select their favorites based on flavor and appearance, but to bakers, distinguishing between these baked products can be a complex task. Copyright © 2020 by authors and Scientific Research Publishing Inc. Biscuits were analyzed for proximate composition including moisture, fat, protein and ash following AOAC (1995) [9] procedures (analyses were carried out in duplicate). Joseph B. Flours from soft wheat cultivars are preferred for biscuit manufacture for their low level of starch damage and weaker gluten. The acceptability of sensory characteristics was improved by this fortification In addition, they concluded that the gluten network should be slightly developed for the dough to be cohesive without being too elastic. Manipulation of a biscuit footplate puts the patient at increased risk for footplate mobilization and SNHL (Fig. Use of the laser allows removal of bone and performance of a footplate fenestra without significant energy transfer to the tenuous footplate. 2.5. In this article, the history and usage of biscuits, cookies, and crackers are examined. 2) Studying some chemical and sensory properties of this product (biscuit enriched with germ wheat). Changes in dimension and texture, loss of moisture, and color and flavor development are the most important. Doescher et al. The basic characteristic that separates a biscuit, cookie, or cracker from other baked products, such as bread or cake, is a moisture content below 5%. Apart from the method of manufacturing, packaging also plays a multiple role, that is, safeguards the product from contamination and attracts the consumer. These changes overlap during the baking process, but it is useful to note that the formation of the structure and texture of the biscuit will take place in the first half of the biscuit baking oven, the reduction in moisture mainly in the middle of the oven and the colour in the final third of the oven. Texture and crispness are of the most important sensory characteristics of biscuits evaluated by consumers. One of the major processing quality attributes of biscuits is their dimensional stability, with retraction and excessive spreading being the two opposite main flaws.224 WU-AXs have been recognized for a long time as detrimental to normal biscuit spreading because of their high water-absorption capacity.225,226 The role of WE-AXs has been more disputed.195,225,227 The extensive degradation of AXs leads to excessive dough spreading but the controlled enzymatic solubilization of WU-AXs appears beneficial, provided that solubilized AXs were sufficiently depolymerized to avoid dough retraction. The results showed that the addition of Therefore, the characteristics of endoxylanases used for biscuit-making should differ from those used for bread-making. 1.46 fiber % and 57.27% carbohydrates. It is known that minerals act as an important cata - lyst in the flow of a number of biochemical processes (2012) studied the effect of partial replacement of wheat flour with a 1:1 mixture of wheat bran and date palm fruit powder on nutritional quality of biscuit. Weegels and Hamer (1989) backed up this idea that soft wheat proteins affect important quality parameters, including dough consistency. This article outlines and describes the chemistry and methods associated with the manufacturing of biscuits. 100% wheat flour was used as control. Other major ingredients are fat or shortening, and sugar. Table 75.3. Fermented soy flour had higher protein content (46.28%) of about twice but lower carbohydrate content (10.14%) of about thrice those of blanched soy flour (20.40% protein and 35.90% carbohydrate). On the other hand, fat and total carbohydrates decreased by 14% and 0.6%, respectively. Biscuit requires a balanced nutritional value which can be enhanced by fortification and supplementation with a wide variety of protein rich cereal and pulses [1] . 1338-0230 1337-0960 Association HACCP Consulting PSJFS-14-1-1176 10.5219/1241 ARTICLE CHEMICAL PROPERTIES AND ACCEPTANCE IN THE BISCUIT FORMULA OF BELITUNG TARO (XANTHOSOMA SAGITTIFOLIUM) WITH ADDITION OF ANT NEST TUBERS (HYDNOPHYTUM FORMICARUM) … Biscuit constituents ranged between 6.06%-7.8% Crude protein, 16.12%-18.39% Crude fat, 1.31%-1.59% Ash and 0.61%-0.91% Crude fiber ; respectively. Studies indicated that addition of pomegranate peel powder or juice in cookies preparation could enhance its nutritional quality without affecting the rheological, sensorial and antioxidant properties [4] [5] . The average chemical composition of biscuits was 5.58% protein 28.05% fat. which contains at least 27% gluten. This is usually wheat but is sometimes oat, barley, rye, or rice. wheat biscuits with high source of protein such as legumes or soy when the texture was enhanced. sensory parameters of this product. Historically, the biscuit industry used large quantities of hydrogenated marine oils. 3.1. All data generated in the study were analysed statistically. Taste and flavor significantly were enhanced by addition of WG, it were evaluated “like moderately” in comparison to “neither like nor dislike” of control sample. Youssef (2015) studied fortification of wheat biscuit with wheat germ at two levels: 15% and 20%. R. Miller, in Encyclopedia of Food and Health, 2016. Range of iodine fortified products targeted at selected age group. RESOURCES, ERC. The dough is extruded through a nozzle and deposited directly onto the oven band. S. Zydenbos, V. Humphrey-Taylor, in Encyclopedia of Food Sciences and Nutrition (Second Edition), 2003. Crackers and some biscuits are docked by pressing blunt pins into the dough sheet. Patients operated on under general anesthesia should have no more than 8 to 10 laser pulses in a row without allowing time for cooling. This could be due to the distinguishable taste and flavor of WG itself that appeared clearly at added level of 20%. The oxidative stability needs to be high for a long-shelf-life product, typically 40 h minimum at 100 °C (measured by Rancimat instrument). Baking time is regulated by the band speed. Horsfall D. Mepba1*, Lucy Eboh2 and S.U. "A Thesis On Chemical Composition, Functional Properties, Sensory Evaluation And Glycemic Index Of Biscuits Produced From Flour Blends Of Unripe Plantain, Soybeans And Carrot". The biscuits were prepared using each ratio of mixed wheat flour and African walnut flour. It is not uncommon for the drier to consist of 5–7 zones. 75:25, and 100:0 respectively and used to produce biscuit. Protein and total minerals increased by about 29% and 49%, respectively. Chemical properties of the jujube were determined. Of importance to dough consistency and biscuit quality are the proteins of the flour, namely the gliadin and glutenin fractions. The fortification levels are determined as a percentage of the daily requirement in a single or daily serve. 20 Jul. Dough expansion and water loss reach maximum rates and colour development starts during the second phase. CHEMICAL COMPOSITION The chemical composition of flours of cassava, wheat, and fermented and blanched soybean are shown in Table 2. Biscuits are widely produced in Jordan both in home and industrial scale. Attempts were being made in recent days to improve the nutritional qualities and functionalities of cookies, due to competition in the market for more healthy, natural and functional products [3] . Therefore, this study aimed at: 1) Determining of the maximum acceptable level of wheat germ that can be added to one of homemade biscuits in Jordan. The word Biscuit derived from Latin word Biscoctum means twice baked. The fraction which is obtained as filtrate is acid-soluble portion while the other fraction is acid-insoluble, which retain on the filter membrane. L. Boothby, in Encyclopedia of Food Sciences and Nutrition (Second Edition), 2003. Biscuit fats can be supplied ready for use in boxes. Biscuit and cookie doughs that are deposited contain the highest level of shortening and sugar in the short dough category. Al-Marazeeq, K. and Angor, M. (2017) Chemical Characteristic and Sensory Evaluation of Biscuit Enriched with Wheat Germ and the Effect of Storage Time on the Sensory Properties for this Product. Preliminary study was carried out for determination of the highest sensorially acceptable level of the added wheat germ to biscuits. Table 3. Docking dough pieces before baking creates air passages through the crust and seals the top to the bottom, reducing big blisters. Biscuits containing the probiotics B. longum Bar33 and Lactobacillus helveticus Bar13 given by Rampelli et al. wheat germ in, biscuit making at level of 20% Table 1. Ash content also increased but not significantly [6] . The samples were evaluated for desirability in appearance, color, crispiness, texture, taste, flavor and overall acceptability using a 9-hedonic scale test as described by Larmond (1991), varying from 9, which means like extremely to 1, which means dislike extremely [8] . Overall acceptability of the preliminary biscuits blends (Table 1) with wheat germ (GB) showed that treatment with 20% WG had the best evaluation that fall within the range of like moderately. Control treatment was prepared without addition of wheat germ to conduct subsequent comparisons. Apart from the good taste, these foods with substantial energy having wholesome and nutritious quality are available at reasonable price. The gluten web is also important in trapping air and gas bubbles formed by yeast fermentation or by leavening agents such as sodium bicarbonate (“soda”) or ammonium carbonate (“vol”). Physical changes in biscuits during baking. Ingredients were mixed together in ratios of about 100% wheat flour, 50% butter, 7% egg, 20% sugar, 0.2% salt, 1.5% vanilla and 0.7% baking powder, then manually kneaded. *Readings were presented as an average of duplicates; **Significant differences at α = 0.05. the proposed substitution showed marked reductions in the values of fat, carbohydrate, and calories. The average energy content of biscuits was 518 Kcal/100g. Care should be used to prevent heat transfer to the vestibule, which may put the inner ear at risk. Blends were carried out using concentrations of 5%, 10%, 15%, 20% and 25% (w/w) added wheat germ as described in 2.1. 0.47% ash. Appearance and color of GB were evaluated in the range of “like moderately” that touch “like very much” in comparison to “like slightly” and the beginnings of “like moderately” of control sample. Scientific Research (1987) put forward the idea that the flour proteins swell when their glass transition temperature is reached—a continuous phase or network is formed which decreases water mobility and increases biscuit dough viscosity, thus stopping expansion of the dough. Walker, in Encyclopedia of Food Sciences and Nutrition (Second Edition), 2003. Table 3 illustrates the sensory characteristics of biscuit treatments (control and with 20% WG) at zero time and after storage for two months at room temperature. Biscuits are one of the low cost processed foods, which are most widely consumed. PSJFS Potravinarstvo Slovak Journal of Food Sciences Potr. Flour blends were produced by substituting guava flour into acha flour at 5, 10, 15, 20, and 25%. J.L. Eimear Gallagher, in Gluten-Free Cereal Products and Beverages, 2008. Biscuits are consumed throughout the world for their nutritional value and also can be stored for longer durations. Biscuit was produced from the composite flours and analyzed for sensory attribute. The flour used for biscuit produc tion is usually white wheat fl our (oatmeal fl our, corn flour, etc.) immediately after preparation and during storage. Major and minor ingredients used during manufacturing of biscuits play an important role, and the chemistry behind them must be well understood by biscuit manufacturers to maintain quality and to avoid batch variations. In general, the biscuits analyzed were low in protein, high in fat and energy. Data were subjected to standard deviation, means, and ANOVA followed by multiple comparisons at α = 0.05 using statistical package for social science [10] . The basic characteristic that separates a biscuit, cookie, or cracker from other baked products, such as bread or cake, is a moisture content below 5%. Chemical composition of biscuits Table 3 shows the content of essential nutrients and dietary fibre in biscuits. Contamine et al. 3) Evaluating the effect of storage time after two months at room temperature on the sensory parameters for this product. Cookies were rich in magnesium (576.54–735.06 mg/100 g) with favorable Na/K ratio (<1.0). Take a piece of living tissue and crush and mix it with an acid. Consumption of biscuit and bread appears in the list of top ten daily consumed foods, and they are easily available and convenient to be enjoyed as snack [2] . Understandably, biscuits and beverages (Table 75.3), the two most commonly preferred foods of children, are chosen for fortification. Web. Fortification of biscuit with 20% WG enhanced these characteristics from “like slightly” to “like moderately”. The jujube After determination of the best sensorially acceptable added level of wheat germ as described in section 2.2, the final treatment of biscuit was prepared as mentioned in section 2.1 by addition of 20% wheat germ. Chemical qualities of the jujube showed protein (1.43%), ash (3.20%), Carbohydrate (24.29%), fat (0.84 %), and moisture (3.80-5.80%). Total carbohydrates were calculated by difference. 2.4. Fortified foods which are to be consumed as such or require minimum reconstitution, provide an opportunity to include known or measured amount of iodine in the diet. Wheat flour was replaced with soy flour and Mushroom was added in biscuits. chemical composition, mineral contents and the microbial analyses of biscuits were studied. The dough pieces are placed on either a flexible metal or wire mesh band that travels continuously through the oven's length, which may reach 100 m. Baking is controlled by varying the temperatures in the individual zones within the oven. Here is a simple experiment to find the Chemical Composition Analysis in Biomolecules.
