sensory evaluation of biscuits

Physicochemical, Textural, and Sensory Evaluation of Reduced Fat Gluten- Free Biscuit Prepared with Inulin and Resistant Dextrin Prebiotic N. Emami1, P. Dehghan2, F. Mohtarami3, A. Ostadrahimi2, M. H. Azizi4 ABSTRACT The aim of this study was to evaluate the effects of inulin (IN) and resistant dextrin (RD) as fat replacer and prebiotic on gluten-free biscuit and its dough. Sensory attributes of all kind of samples were evaluated in fresh condition and after 60 days of ambient storage. Ash content also increased but not significantly [6] . During the sensory evaluation, the highest scores were received with addition of 1 and 3% chicory fiber extract. Water was used to neutralize the taste between samples testing. 3.3. In our case, the acceptability of the biscuits formulated with artichoke fiber‐rich powders was similar to that of the biscuits with pea fiber. wheat germ in, biscuit making at level of 20% Dough and biscuits were evaluated for physical, nutritional and textural properties, particle size, colour and sensory evaluation and compared against refined-flour biscuits (C). PRODUCING AND SENSORY EXAMINE THE BISCUIT USING WHEAT FLOUR CASSAVA FLOUR ABACHA FLOOR AND AFRICAN YAM BEAN FLOUR. On the contrary, the variables appearance and texture are not explained well by the model, since they are close to the centre of both principal components. As the control for each group of biscuits, the values were taken at time 0, which was the day after preparation. Yacon (Smallanthus sonchifolius) is a sweet-tasting tuber, grown in the Andes Mountains and considered a functional food because of its fructooligosac… The intensity of the attributes was classified on non‐structured, continuous graphic scales. Thereafter, a 50-member panel evaluated coded biscuit The order of presentation of the biscuits was balanced using all of the presentation combinations possible on the tasting sheet. 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. Sensory Evaluation 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 tempera- ture. 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. In conclusion, the evolution of the sensory qualities of the biscuits formulated with artichoke fiber‐rich powders (W, Ca) was similar to that of the biscuits formulated with pea commercial reference fiber (P), and thus that its better sensory appreciation would be maintained throughout the accelerated storage. Afterwards, the biscuits were cooled at ambient temperature (18–20°C) and wrapped in heat‐sealed bags of high‐density polyethylene. Sensory attributes evaluated include flavour, colour, crispiness, appearance, sweetness, after taste attributes, texture, and overall acceptability. The study carried out the production of biscuit spiced with four different spices which have nutrition and health benefit. Values are means ±, Organoleptic properties (Color; Appearance, Flavor, Taste, Texture, Overall acceptability). These results agreed with Chioma and Chizoba (2015) who reported that incorporation of African yam bean flour with wheat flour at ratio of 10:90 enhanced the color and aroma of wheat biscuit [14] . 2) Studying some chemical and sensory properties of this product (biscuit enriched with germ wheat). Dough was sheeted and cut into round shape with same sizes of about 5 mm in thickness and 50 mm in diameter. M. Collado‐Fernández, Departamento de Biotecnología y Ciencia de los Alimentos, Universidad de Burgos, Burgos, Spain. Thus, the absence of characteristic flavor and taste was rated below the standard value, like loss of characteristic flavor or taste when tastes or smells related to oxidative processes were detected, being a strong flavor and taste of rancidity the lower end of the scale. Before the sensory analysis sessions, the samples were tempered for 30 min, at a temperature of the sensory analysis room (25°C). 2.3. Ahmed. 2, No. Storage at accelerated temperature of biscuits formulated without fiber (B), and with fiber of Pea (P) and fiber‐rich powder of Artichoke (W, Ca), for 0, 2, 4 months. The result of proximate composition of the flour sample indicated a protein content of 7.8%, ash content of 3.2%, fibre content of 0.5%, fat content of 4.5%, moisture content of 11.5% and carbohydrate content of 72.5%. 3.1. Biscuits sensory evaluation was carried out using 10-points hedonic scale. When looking at the groups that were formed in the PCA‐statis plot individually, it is observed that throughout the 4 months of storage at ambient temperature the groups of biscuits formulated with vegetal fibers remained grouped more closely. Numerous studies confirm that vegetable fiber prevents diseases such as gastrointestinal disorders, duodenal ulcer, constipation, hemorrhoids, Type II diabetes, obesity, cardiovascular diseases, (Afaghi, Kordi, & Sabzmakan, 2015; Vitaglione, Napolitano, & Fogliano, 2008) and kidney stones (Sorensen et al., 2014). Sensory and textural evaluation of gluten-free biscuits containing buckwheat flour. The samples tested during the sensory analysis were samples randomly selected from each of the three pilot plant batches. Total calories of biscuit without germ were 477.84 kc/100 g, while those for biscuit with WG were 462.13 kc/100 g in difference of 15.71 kc/100 g in comparison with the control one. (2015) who concluded that incorporation of maize bran and carrot extract into wheat flour in biscuit production enhanced consumer’s taste and flavor [13] . Comparable objective and sensory results indicated that crust colour was lightened … Addition of wheat germ in biscuit making at the level of 20% (w/w) enhanced its nutritional value by increasing protein and total mineral contents, as well as decreasing fat, total carbohydrates and total calories. *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 biscuits stored under ambient conditions were analyzed bimonthly, during the 4 months, while the biscuits stored under accelerated conditions were analyzed every 3 months until completion of the 6 months of storage. The presentation of the biscuit samples was performed in a blind fashion, coding each sample with a random numeric code of three digits. In recent years, there has been an increase in demand of gluten free products that are suitable for people with celiac disease. Sensory characteristics of biscuits. This is conducted on randomly selected biscuit samples that are evaluated for the above factors in order to make sure they are within the ideal ranges (Larmond, 2007). 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 effect of other added wheat germ concentrations and storage time on this product was not studied [7] . Thus, the present finding suggests that value-added biscuits could be produced by supplementing purple rice flour up to 50%. These results conclude that the utilization of fiber‐rich powders from artichoke by‐products (Ca, W) can be a viable alternative for the enrichment of biscuits as well as other oven‐baked products and that it could be a suitable substitute for commercial pea fiber. Use the link below to share a full-text version of this article with your friends and colleagues. The ways of extraction of by‐products of artichoke into fiber‐rich powders modify their industrial applications in biscuits, as the sensory evaluation may change compared with the reference fiber (Pea fiber, P) used with commercial biscuit. width, aspect ratio at max. Wholegrain buckwheat and rye flours were used to partially replace wheat flour in honey biscuit formulation. Blends were carried out using concentrations of 5%, 10%, 15%, 20% and 25% (w/w) added wheat germ as described in 2.1. Final Preparation of Biscuit Treatment. Laboratory Report For Practical – Sensory Evaluation And Biscuit Shelf LifeIntroductionThe introduction should state the problem and outline the method for tackling the problem. Therefore, it is recommended to utilize this valuable byproduct in production of biscuits to gain more nutritional and sensorial properties of this product. CLICK HERE TO DOWNLOAD THE COMPLETE MATERIAL (CHAPTER 1 -5) While sensory evaluation gives a judgement of the overall acceptability of a product, and objective method to evaluation is only able to measure one aspect of food, and this may not always be sufficient to determine whether a quality of the product is acceptable. Sensory characteristics of the all four samples were determined by taking the sensory attributes flavour, colour, taste, texture, and overall acceptability. The parameters evaluated such as appearance, colour, flavour, aroma, taste, texture and overall acceptability. With respect to color, the use of both artichoke fiber‐rich powders (Ca, W) modifies the color of the biscuits, making them darker than the biscuits formulated with pea fiber, due to its more neutral color. They have good shelf life at ambient temperature. Sensory quality characteristics were evaluated by a panel of 10 semi-trained members using a 9-point Hedonic By H.M. E. Hag, A.H. El Tinay and A.R. The results indicated that protein, fat content, fiber, iron and energy value of soy flour-supplemented biscuits increased.

This is explained by a lack of significant variation in the sensory qualities and therefore, due to an effect of protection of the sensory qualities by the enrichment of the biscuits with vegetal fiber, or at least an effect of masking the changes in color and taste. Storage at accelerated temperature of biscuits formulated without fiber (B), and with fiber of Pea (P) and fiber‐rich powder of Artichoke (W, Ca), for 0, 2, 4 months. Five differently coded samples i.e. (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. The presentation of the sample to the panelist was as follows: using white light, the four hold biscuits were presented together on a piece of white paper divided into four equal parts, in which the codes of the biscuit were printed randomly. The panelists were from both sexes, and from different ages, they were requested to taste each sample separately without comparing it with another sample. However the color and taste of cookies made from 50% rolled oats was good and acceptable. Then the prepared biscuits were sensorially evaluated by 5 trained panelists chosen from the teaching staff and technicians of the Department of Nutrition and Food Technology, Al-Huson University College. Protein and total minerals increased by about 29% and 49%, respectively. increasing protein and total The score of taste reduced significantly to 2.53. Control treatment was prepared without addition of wheat germ to conduct subsequent comparisons. In this study, biscuits were prepared by enrichment with onion residue (OS). This work aimed at determining the maximum acceptable level of wheat germ that can be added to one of homemade biscuits in Jordan, studying some chemical and sensory properties of this product, moreover, studying the effect of storage time after two months at room temperature on the sensory parameters of this product. The dough was kneaded with a pilot mixer during 10 min at minimum speed. In the first principal component, the variable color and overall acceptability were correlated with the biscuits formulated with artichoke fiber‐rich powders (Ca, W) separating them from biscuits B and P. Thus, if the color of the biscuits is darker, this is related to an increase in the values of overall acceptability.

The confectionery products such as cakes and biscuits were also developed during the course through artisanal process using a household mixer (Power Chef planetary model, PHILCO), and manual cookie modelers of various shapes. Assuming that the by‐products have a composition similar to the edible part of the artichokes, these by‐products can be a promising source of new value‐added compounds such as phytochemicals and fiber (Ruiz‐Cano et al., 2014). Biscuits were subjected to sensory evaluation at different sessions by panels of 50 untrained students drawn among the student population of the University of Ngaoundere, Cameroon. In this sensory study biscuits enriched with fiber‐rich powders of artichoke (W, Ca) are compared with biscuits with the same percentage of the reference fiber (P) and control biscuits without fiber (B). As shown from this table addition of 20% WG significantly enhanced all the sensory characteristics of wheat biscuit. The vocabularies of the sensory attributes were agreed upon in order to describe the differences between samples. Table 3. PCA‐statistical analysis explained 89.8% of the variation in the sensory attributes of the biscuits; principal component 1 (PC1) explained 75.5% and the second component (PC2) 14.3% (Figure 5). As shown from this table addition of 20% WG significantly enhanced all the sensory characteristics of wheat biscuit. In order to be able to describe the possible sensory defects, like the appearance of strange flavors and odors caused by the accelerated storage, the consensus on the sensory variables taste and flavor was differentiated.

The various fat replacers were substituted for fat in the biscuit formula at a rate of 33%, 66% and 100%. The artichoke by‐products from the canning industry are mainly used for silage, being minimally revaluated. Biscuit quality was assessed by spreading behavior, texture and surface characteristics, chemical properties, and sensory evaluation. 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. The PCA decomposes the viability of a group of data in principal components and tracks the panelist in the principal component space according to their valuations of the samples together with the average classifications of the samples or attributes. Values are means ±, Two‐way ANOVA (1 rep) sample means & LSD. This could be due to increasing fiber content of biscuit by addition of WG that modified these two parameters. 1, 1178693. Therefore, the absence of characteristic flavor and taste was rated below the standard value, while flavor and taste were rated above the standard value, up to very roasted or burnt as the upper end of the scale. In this sensory study biscuits enriched with fiber‐rich powders of artichoke (W, Ca) are compared with biscuits with the same percentage of the reference fiber (P) and … level of wheat germ, that can be added to one However, there are no commercial products of food fiber‐rich powders of artichoke yet, although it would be very interesting to study their possible industrial appliance. It was also demonstrated that the biscuits formulated with artichoke fiber‐rich powders (Ca, W) had a similar behavior during storage to that of the biscuits formulated with the commercial reference fiber (P). Biscuits are one of the low cost processed foods, which are most widely consumed. 2.8 Sensory evaluation of biscuit. Proximate analyses (Table 2) of biscuit treatments indicated that fortification of biscuit (B) with 20% WG significantly (p ≤ 0.05) increased protein and total minerals, while decreased moisture, fat and total carbohydrates. Appearance is related to the geometry and the structure of the biscuits, and the outer ends of appearance went from an irregular biscuit with an irregular surface produced by evaporation bubbles, to a very compact biscuit with a smooth surface. Values are means ±, PCA‐statis biplot of the sensory profile of the biscuits by descriptive method. The taste of all biscuits enriched with fiber was appreciated as similar by the panelist. Research Article Effect of Substituting Purple Rice Flour for Wheat Flour on Physicochemical Characteristics, In Vitro Digestibility, and Sensory Evaluation of Biscuits … She found that biscuits with added 20% wheat germ had the best chemical, nutritional and sensory characteristics than 15%. Compared to t … Evaluation of the six biscuit treatments and a commercial whole grain wheat biscuit (McVitie’s Wholewheat Digestives, United Biscuits, United Kingdom) was replicated three times in sessions of 1.5 h a day for 3 days. For the biscuits subjected to accelerated storage, the PCA‐statis analysis explained a total of 82.4% of the variation in the sensory attributes of the biscuits; the first principal component 1 (PC1) explained 65.2% and the second (PC2) 17.2% (Figure 8). Wheat flour was replaced with soy flour and Mushroom was added in biscuits. 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] . Moreover, this product is widely consumed by different ages due to cheapness, ease of handling and its nutritional value, however, this product suffers protein and dietary fiber deficiency. The CB, SB-5%, SB-10% and SB-15% were subjected to sensory evaluation of ten trained panelist from CSIR-CFTRI-RC, Hyderabad, India on their familiarity with the biscuits were used for the evaluation. This effect on the decrease in the percentage of explanation of the first principal component is caused by the conditions of accelerated storage and the increase in the explanation of the model of more sensory variables, like taste and flavor. immediately after preparation and during storage. Consumer trends demand more natural products with better nutritional characteristics which can complement nutritional deficiencies, like the low fiber ingestion (Arrillaga & Martínez, 2006; Milte, Thorpe, Crawford, Ball, & McNaughton, 2015; Mongeau, Brassard, & Verdier, 1989). Since these clear differences between biscuits without fiber and the rest were maintained throughout accelerated storage, and because the biscuits formulated with fiber‐rich powders of artichoke (W, Ca) could not be distinguished, the percentage of explanation of the first principal component decreased. Water was served to the evaluators for cleaning of the mouth between the different samples. The data were expressed as Mean ± Coefficient of variation (CV). These features improved as the level of acorn flour increased. Cassava root from one year old was used for the production of Abacha flour. Statistical analysis of the sensorial measurements was carried out with the sensory analysis software Panel Check. Both the descriptive and discriminatory evaluation methods were used (Iwe, 2002). The ration of consumption was one whole biscuit of each reference, maintained at a temperature of 25°C. Biscuits are one of the most consumed bakery products eaten by everyone. These results agreed with Youssef (2015) who found that wheat biscuits supplemented with wheat germ proved to be nutritious and healthful food by increasing crude protein and crude fiber, while lowest fat and caloric values [7] . Besides being a very palatable vehicle of nutrition and energy, these biscuits convey the goodness of flour, fat and sugar in most acceptable and economical term [1] . Cookies were placed on a baking tray inch distance and were baked at 175°C in a baking oven for 10-15 min. This was partly because of the fact that the initial color of the biscuits B was lighter than that of the rest and therefore small variations in color were more perceptible by the panelist than in the biscuits with plant fiber, which were darker due to the color of the fiber. These results agreed with [5] [15] . The samples were judged without replicate. Overall acceptability of preliminary blends.
