Selected biscuit formulation (F2) per 100 g contains 534.8 kcal of energy, 18.8 g of protein, 33.0 g of fat, 40.49 g of carbohydrate, and 18.08 g of dietary fibre.

Development of Banana Peel Powder Incorporated Functional Cookies

Nendran Banana is one of the most common fruits consumed worldwide, and it contributes significantly to the waste produced by food consumption. Banana peel waste has a significant amount of food fibre, phenols, flavonoids, antioxidants, antibacterial, and anticarcinogenic substances. Repurposing banana processing waste, such as peel, has the potential to boost raw material output and, as a result, reduce food industry waste while simultaneously improving the availability of nutritional and nutraceutical potential among the human population. This study is aimed to assess the nutritional, functional and bioactive compounds of prepared nendran banana peel flour and its incorporation in to various proportion of cookies formulation. Nendran bananas were purchased from a local market, sorted, peeled, soaked in 2% lime juice for 15 minutes, dried, powdered with a mixer grinder, sieved to produce a fine powder, and analysed for physical and functional properties such as length, width, and dimension, water and oil holding capacity, swelling powder, and proximate composition such as moisture, ash, carbohydrate, protein, fat, and fibre. The approximate composition of the banana flour was determined using AOAC standard techniques. Bioactive components were also assessed. The two varieties of cookies were prepared with the incorporation of nendran banana peel powder at the rate of 5 % and 10% and analysed for their nutritional components. The functional features of nendran banana peel powder revealed that it had a higher water-holding capacity, good oil-holding capacity, high solubility, and a high swelling capacity. Nendran Banana Peel Flour was discovered to be high in protein and crude fibre. It possesses greater antioxidant scavenging activity as well as possible polyphenolic substances. The produced food formulation was organoleptically evaluated using a 5-point hedonic rating scale, and the best product was chosen based on the sensory scores. The study suggested that the nendran banana peel flour is a versatile nutritional supplementation and provides a great health impact.

Carbon quantum dots with ultra-high quantum yield for versatile turn-on sensor of gluten and cyanide Ions

In this work, we reported the synthesis of carbon quantum dots (CQDs) with high fluorescent quantum yield (90.7 %). These nanoparticles were applied in a turn-off/turn-on sensor able to detect cyanide ions. In this sensing strategy, Fe3+ ions were added to the aqueous suspension of CQDs to quench the fluorescence of the system, which was recovered from the presence of cyanide ions. Furthermore, a sensor array was developed using the LDA chemometric tool, to classify different species present in cookie formulations, including gluten. The turn-off/turn-on sensor proved to be sensitive and effective for detecting cyanide ions, with a detection limit of 3.77 ppm. This high sensibility and selectivity allowed quantifying the analyte in a real sample of tap water.

Pigmented sweetened rose petal crush enriched multi-millet cookies: investigating the physical properties, phytochemistry, molecular and structural transformations

Purpose This study aims to investigate the use of rose petals rich in bioactive components possessing several health benefits in the form of pigmented sweetened rose petals crush (P SRP C) at varying levels in the formulation of cookies to develop consumerfavored natural flavored food products. Design/methodology/approach PSRPC was used as functional ingredient in millet cookies at varying levels of 5%, 10%, 15% and 20%. Developed cookies were evaluated for physical parameters, bioactive components along with their associated antioxidant activity, texture (hardness, fracturability), surface morphology and molecular interactions. Most acceptable cookies were selected on the basis of sensory evaluation. Findings Cookies formulated from millet flour were significantly different from wheat flour cookies. Furthermore, the incorporation of PSRPC in millet cookies increased the total phenolic content, flavonoid content and antioxidant activity. Texture analysis results showed that cookies with higher level of PSRPC had lower hardness and fracturability. PSRPC-incorporated cookies were darker and redder due to the pigments found in rose. Surface morphology and functional groups were altered on addition of PSRPC. Cookies incorporated with 10% PSRPC were highly acceptable on the basis of sensory score. Originality/value The current study developed newer conditions for development of cookies from PSRPC. Results foresee the potential of PSRPC as a functional ingredient in value-added food products having health benefits.

Valorization of Pumpkin Flour in Cookie Formulations: Effects on Nutritional Composition and Mineral Content

Pumpkin is a highly nutritious food that offers protective benefits against various health conditions, such as diabetes, cardiovascular diseases, constipation, appendicitis, hemorrhoids, and colon cancer. This study aimed to examine the proximate composition of pumpkin-wheat cookies. An experimental research approach was employed to produce pumpkin powder, incorporate it into cookie production, and analyze its nutritional constituents. The results revealed that as the proportion of pumpkin flour in the composite flour increased, there was a corresponding increase in moisture, ash, fat, protein, and fiber content. Additionally, the study demonstrated an increase in mineral content with higher amounts of pumpkin. The iron and manganese levels ranged from 244.1mg/kg to 312.1mg/kg and 74.52mg/kg to 88.17mg/kg, respectively. Calcium and potassium contents also ranged from 0.24% to 0.40% and 0.39% to 0.57%, respectively. The beta-carotene content of the samples varied between 0.18mg/kg to 0.57mg/kg, while the folic acid content ranged from 13.7ug/g to 144.95ug/g.

Strategies to mitigate acrylamide development in bakery products: Effect of asparagine content in flour and tartaric acid addition in biscuit formulation

This paper explores strategies to mitigate acrylamide formation in bakery goods, with a focus on using tartaric acid as an acid neutralizer in biscuit recipes. Initial analyses involved screening the asparagine content in various flours, aiming to encompass a wide range of samples, including those that presented substantial challenges. Subsequently, experimental biscuits were produced with various treatments (tartaric acid addition, steam release during baking, and both steam/acid). Results showed a correlation between asparagine content in flours and acrylamide formation. Tartaric acid was remarkably effective, achieving a 57%–87% reduction in acrylamide production. Colorimetric measurements assessment demonstrated that tartaric acid treatment reduced browning, while the aw (<0.15) was not affected even using steam during cooking. Sensory analysis indicated slight sour taste in acid-treated biscuits, but overall acceptability remained high. Texture analysis revealed improved friability, crucial for preventing oral mucosal lesion, especially in children's products. PCA highlighted the impact of treatments on variables like acrylamide content, color, water activity, and sensory attributes. The study suggests that using tartaric acid as a neutralizing agent is a solid strategy to mitigate acrylamide without compromising sensory qualities in biscuits. Further research will include exploring other acids, optimal dosage, and variations in flour composition.

Milk Proteins as Alternative Ingredients Replacing Sugar and Their Effects on Chemical, Technological and Sensory Quality of Cookies

ABSTRACT This paper aims to evaluate nutritional, technological and sensory characteristics of cookies with reduced sugar content and added milk proteins. Five formulations of cookies had their weight, height, weight loss, yield, apparent volume, specific volume, spread ratio, color, pH, texture, proximate composition, acceptability, purchase intention and acceptability index were evaluated. Cookies made with low sugar presented promising quality for apparent volume, specific volume, spread ratio and yield. High protein and ashes content, lower moisture and low sugar concentration were also observed. Treatments added with whey protein highlighted in the sensory analysis and reached a satisfactory acceptability index. Cocoa powder can covered up the sugar reduction and can be used in cookies formulation to diminish sugar. Casein did not show potential as an alternative for cookies. Cookies produced with low sugar and added with whey protein had appropriate chemical, technological and sensory characteristics.

Sensory evaluation of pumpkin flour-wheat flour composite cookies: Exploring nutritional enrichment and consumer acceptance

The study comprehensively evaluated the consumer acceptability and sensory characteristics of cookies made from varying ratios of pumpkin flour and wheat flour. The researchers incorporated pumpkin flour at four different levels - 0%, 40%, 50%, and 80% - into the cookie formulations. To assess the sensory profile of these cookie samples, the researchers conducted a thorough evaluation using a 7-point hedonic scale. This scale allowed panelists to rate their level of liking or disliking for key sensory attributes, including color, aroma, taste, aftertaste, and texture. The results of this sensory analysis revealed some interesting trends. As the substitution level of pumpkin flour increased, there was a significant decrease in consumer preference for the color, aroma, and taste of the cookies. However, an intriguing finding was that the aftertaste was actually improved with higher pumpkin flour content. Notably, the cookies made with a 50% pumpkin flour to 50% wheat flour ratio were most preferred by panelists in terms of texture. This suggests that a balanced approach to the flour blend, incorporating a considerable amount of pumpkin flour, can produce cookies with an acceptable and even desirable textural profile. The study demonstrates the potential of pumpkin flour as a nutritious ingredient that can be incorporated into cookie production. The nutritional benefits of pumpkin flour, such as its high content of beta-carotene, fiber, and other vitamins and minerals, make it an attractive alternative to traditional wheat flour. However, the researchers caution that higher substitution levels of pumpkin flour, beyond the 50% ratio, may require further optimization to enhance the overall sensory acceptance of the cookies. Finding the right balance between nutritional enhancement and maintaining desirable sensory attributes will be crucial for the successful development of pumpkin flour-based cookies that appeal to health-conscious consumers.

Pasta Drying Defects as a Novel Ingredient for Hard Dough Biscuits: Effect of Drying Temperature and Granulation on Its Functionality.

Various drying temperatures impact the texture of pasta and cause different drying defects. These by-products could reflect techno-functional characteristics which are suitable for cereal products. This research addresses the influence of low (LT) and high (HT) drying pasta defects with two granulations on the theoretical and functional characteristics of hard dough biscuits. By shifting from a LT to HT drying temperature, a higher onset and peak temperature was found due to the higher mobility of starch molecules with increasing crystalline stability. The lowest transition enthalpy of biscuit formulation was also observed for higher incorporation of fine HT pasta regrinds. The algebraic model of dough with consistography determined the poor-extensible gluten and a high resistance with a greater value of P/L and P indices for LT regrinds. Scanning electron microscopy revealed a heavy and dense texture with immersed starch granules for additional fine regrinds while coarse samples caused swell granules with greater diameter. Moreover, fine HT regrinds reflected the lowest L* value for biscuit due to heat gradient tension with the hard milling process which leads to protein denaturation with decreasing nitrogenous.

Circular bioeconomy for cocoa by-product industry: Development of whey protein-cocoa bean shell concentrate particles obtained by spray-drying and freeze-drying for commercial applications

The revalorization of cocoa (Theobroma cacao L.) processing wastes, mainly cocoa bean shells, involve some strategies to obtaining maximum benefits of the bioactive compounds and reducing the amounts of waste through its use in new products in the context of the circular bioeconomy. Cocoa bean shells were used to obtain a phenol concentrated and formulate a matrix with isolated whey protein particles. Spray-drying and freeze-drying were used to pulverize the samples. The results indicated that both methods improve the stability of the compounds and the antioxidant capacity of the phenol-protein matrix powder, with significative differences (p<0.05), being the spray-dried matrix the sample with the higher amounts of the total polyphenols. Different amounts of the phenol-protein matrix powder obtained by spray-drying and freeze-drying were used for the formulation of the cookies, and significant differences (p<0.05) were observed in the physicochemical characteristics, proximal analysis, bioactive compounds and antioxidant capacity, among the formulations. The cookies with the highest protein content were those to which a 12.5 and 20% of the matrix obtained by freeze-drying was added. While the cookies with the highest content of total phenolic compounds (4118.72±27.43) and highest values of antioxidant capacity (521.33±33.68 mmol Trolox/g and 4249.10±51.24 FeSO4/g, by DPPH and FRAP assay, respectively) were those that were added with 20% matrix obtained by spray drying. Likewise, the discriminating variables identified between the cookie formulations were the results of polyphenols, DPPH, FRAP and proteins. This indicate that the addition of a phenol-protein matrix powder as an ingredient in cookies, as comercial application, exhibited an increasing of proteins and polyphenols content, including higher values of antioxidant capacity, in the final product.

Development of cookies made from red kidney beans, oyster mushroom, catfish and fermented soybean flours as a food alternative for stunting kids in Indonesia

The study developed cookie formulation using available local-based ingredients as an alternative for wheat-based cookies. The cookies were formulated using 2 main ingredients dominated by a mixture of red kidney bean with tempeh flour (BT-OC) or with catfish flour (BC-OT) in addition to oyster mushroom and tempeh flour as 2 minor ingredients. Compared to the high-catfish flour, the high-tempeh formulation allowed a higher rate water evaporation from the cookie matrix. All the cookies met the required standards for protein, fat content and calorie. High-tempeh formulation contained a higher level of ash content compared to that in high-catfish formulated. All formulated cookies contained a higher level of Fe (24.1–66.2 mg/Kg) than that in wheat-based cookies; Zn content ranged at 1.5 – 21 mg/Kg which was comparable with wheat-based cookies. High-tempeh formulated cookies had higher acceptability compared to the high-catfish one in terms of color, texture, taste and aroma. The results demonstrated the potential of developed cookies as functional food and as alternatives for wheat dependency thus providing low-price and nutritious food products which is expected to improve the nutritional status of stunted kids.

Biscuit production from composite flours of wheat and yellow maize: A linear programming, physicochemical, and quality-based approach

Food enrichment plays a critical role in the food industry, with a significant influence on the nutritional value of various food products and their potential health advantages when consumed. The demand for nutritious food products has led to significant advancements in the technology used for the production of biscuits, with the aim of enhancing their nutritional characteristics. Therefore, the objective of the present work was to develop nutritionally optimised biscuits using a linear programming model. The study focused on the optimisation of biscuit ingredients, specifically wheat and yellow maize flour, with or without moringa leaf. The formulation process involved the use of conventional methods and a linear programming model. The resulting biscuits were then analysed for their proximate, sensory, functional, and anti-nutritional properties. The biscuits formulated using the linear programming (LP) model exhibited superior qualities compared to other groups. These biscuits had a protein level ranging from 17.5 to 15.4%, and significantly improved organoleptic properties. The concentration of anti-nutritive compounds showed a notable decrease in the LP group compared to the conventionally prepared biscuits. Therefore, the use of a linear programming model can be adopted for the formulation of biscuits that have high nutritional value.

Peach palm flour had low moisture content (6.15%), protein (4.82%), and fiber (5.07%); however, it had a considerable carbohydrate content (77.62%), energy value (386,84 kcal), and carotenoids. The technological properties showed a high rate of water and oil absorption and emulsifying activity; however, it did not show foaming capacity or gel formation. The replacement of corn flakes by peach palm flour showed an increase in fiber, ash, lipids, and carotenoids and intensified the orange color of the cookies.

The effect of germinated black lentils on cookie quality by applying ultraviolet radiation and ultrasound technology.

Black lentils contain protein, carbohydrates, dietary fiber, minerals, and vitamins, as well as phytochemicals and various bioactive compounds. Ultraviolet (UV) radiation and ultrasound (US) methods are innovative technologies that can be used to increase the efficiency of the germination process in grains and legumes. To improve the nutritional value and bioactive compounds of the cookies, black lentils germinated by applying UV radiation and US technology were used in the cookie formulation. Before the germination process, UV, US, and their combination (UV+US) were applied, and pretreated and unpretreated germinated black lentil flours were used at a level of 20% in the cookie formulation. The results revealed that pretreatment application increased the total phenolic content and antioxidant activity more than the lentil sample germinated without any treatment. In addition, the pretreatments applied further reduced the amount of phytic acid in black lentils and the lowest phytic acid content was obtained with the UV-US combination. Compared to cookies containing unpretreated germinated black lentil flour, higher L* values and lower a* values were obtained in the cookie samples containing pretreated germinated black lentil flour. Cookies containing all pretreated germinated lentils generally exhibited higher Ca and K content. This study demonstrated that UV radiation and US improved the nutritional value and bioactive components of the germinated black lentil flour and the cookies in which it was used, compared to the black lentils germinated without any treatment. PRACTICAL APPLICATION: Pretreatment of black lentils with UV/US application before germination resulted in a greater increase in total phenolic content and antioxidant activity compared to the control sample. The applied pretreatments caused a further decrease in the amount of phytic acid in black lentil samples. Black lentils germinated with the UV+US combination revealed higher Ca, Fe, K, and Mg content compared to the sample germinated without any treatment.

Exploitation of Aureobasidium pullulans NRRL Y-2311-1 xylanase in mulberry and rice flours-based gluten-free cookie formulation: Effects on dough properties and cookie characteristics.

Xylanases are mainly utilized in bakery industry for the hydrolysis of dietary fiber-based fractions. Their applications in gluten-free products have not been considered before. In the present study, the xylanase produced by Aureobasidium pullulans NRRL Y-2311-1 was utilized in a mulberry and rice flours-based gluten-free cookie formulation for the first time. Effects of various xylanase concentrations on gluten-free dough rheology and cookie characteristics were elucidated. Only rice flour-based cookie and only wheat flour-based cookie formulations were also prepared as comparison. Incorporation of xylanase into all cookie recipes resulted in softer cookie doughs with lower absolute stickiness. The hardness and absolute stickiness of the cookie doughs prepared by the mixture of mulberry and rice flours decreased by the addition of the enzyme into the formulation in a concentration-dependent manner. Enzyme concentrations above 100U/100g flour did not provide statistically significant further changes on gluten-free cookie doughs. Incorporation of xylanase into the cookie recipes resulted in increased baking loss and spread ratio in an enzyme concentration-dependent manner for all cookie types. Hardness values of both types of gluten-free cookies decreased by xylanase incorporation. Different effects on fracturability were observed depending on the cookie type and enzyme concentration. Enzyme concentration of 100U/100g flour provided mulberry and rice flours-based cookies with a more flexible and softer structure. No significant effects on color parameters of cookies were observed by xylanase incorporation.

Developing Healthier Biscuit Alternatives: An Analysis of Tapioca, Desiccated Coconut, and Wheat Flour Blends

This study aimed to identify the optimal biscuit formulation using blends of tapioca flour, desiccated coconut flour and wheat flour. Four formulations, denoted as F1, F2, F3, and F4 with varying ratios of wheat flour, tapioca flour, and desiccated coconut flour (30:20:50, 30:30:40, 30:40:30, and 30:50:20 respectively), were produced. Multiple methodologies were employed to study the impact of composite flour on the quality of cookies, including sensory evaluation, proximate analysis, and physical evaluations. After a hedonic test involving 50 panelists, F3 emerged as the superior formulation. Proximate and physical analyses for F3 and the control (100% wheat flour) revealed notable differences. The proximate composition results showcased distinct differences between the best formulation (F3) and the control. F3 exhibited higher values (p&lt;0.05) in moisture content (2.33±0.37%), crude fibre (4.05±0.02%), and carbohydrate content (65.04±0.74%) compared to the control. However, both formulations displayed similarities (p&gt;0.05) in terms of spread ratio, colour, and pH, despite their differing composition in formulation. Notably, F3 surpassed the control in nutrient composition, especially in moisture, crude fibre, and carbohydrate content. In conclusion, the investigation into these blended flours has demonstrated promising outcomes, emphasising their potential to not just enhance the nutritional quality of biscuits but also elevate consumer contentment.

Non-Traditional Vegetable Raw Materials Use in the Yeast-Free Biscuits Technology

Biscuits fall into the dry biscuit category, have a long shelf life and are technologically suitable for enrichment with non-traditional vegetable raw materials. The study aim is to improve the production technology of yeast-free biscuits using non-traditional vegetable raw materials – vegetable powders obtained from pumpkin and carrots. The researchers modernized classic recipe of biscuits “Arctica” by (I) the partial replacement of premium wheat flour with vegetable powders (pumpkin and carrot) at a concentration of 5 % and barley flour at a concentration of 30 % of the total weight of premium wheat flour and (II) butter replacement with a structured fat base (sunflower oil and hydrated potato starch). The thesis demonstrates the organoleptic, physico-chemical characteristics, nutritional and energy value of the developed yeast-free biscuits compared to the control sample. A man determined that the butter replacement with a structured emulsion of sunflower oil and hydrated starch enable to eliminate the saturated fat content in the biscuit formulation. The developed yeast-free biscuits have satisfactory consumer characteristics, a richer chemical composition with the same caloric content as the control sample, mainly due to the content of dietary fibers, minerals and vitamins contained in non-traditional vegetable raw materials.
