Valorisation of apple pomace for the development of high-fibre and polyphenol-rich wheat flour cookies

Apple pomace, abundant in dietary fibre and polyphenols, often goes unutilized, contributing to environmental pollution as it is discarded in open fields of Jammu and Kashmir. This study aimed to develop functional cookies fortified with apple pomace powder (APP), an industrial by-product. Wheat flour-APP formulations (0%, 5%, 10%, and 15%) were assessed. APP addition notably affected color values and functional properties, enhancing water and oil absorption capacities, swelling power, foam capacity and stability. Phenolic content increased significantly (p < 0.05) post-fortification, elevating antioxidant properties. FT-IR spectroscopy identified distinctive chemical components in wheat flour and APP. Sensory evaluation favored cookies with 10% APP, indicating their potential for consumer acceptance. Thus, APP shows promise for producing innovative functional cookies, improving consumer health, utilizing industrial by-products, and reducing waste from apple processing plants, thereby mitigating environmental pollution.

Nutritional, physicochemical, and sensorial characterisation of quinoa-millet enriched gluten-free functional cookies

AbstractThe demand for gluten-free food products is expected to grow in the coming years. Quinoa's versatility allows it to replace traditional grains and adds high nutritional value to grain blends and processed food items. The present study was designed to prepare and evaluate gluten-free cookies by substituting rice with quinoa and keeping pearl and foxtail millet constant. A significant increase in protein (8.0–13.2 g/100 g), crude fibre (2.9–6.2%), ash (0.5–1.7%), and hardness (928.9–1736.9 g) was observed with increasing quinoa supplementation. A positive correlation of crude fibre with protein, hardness, and fracturability was observed at P ≤ 5%. Organoleptic evaluation indicated that cookies with 30% quinoa were overall accepted by the consumer. Also, these cookies had lower acid and peroxide values, thus, had longer shelf-lives. This is the first report for the use of quinoa with the mixture of rice and millet, which could be a decent alternative ingredient for gluten-free cookies formulations.

Utilization of artichoke (Cynara scolymus L.) by-products for enhancing nutritional value and phytochemical content of cookies

This study was conducted to make functional cookies using powdered artichoke stems and bracts, which are rich in phytochemicals. The chemical composition and phytochemicals in wheat flour, artichoke bract powder, artichoke stem powder and the produced cookies were determined. Physical properties, color and sensory characteristics were determined in wheat flour cookies, artichoke bract powder cookies and artichoke stem powder cookies. The results showed that artichoke bract powder cookies (15%) contained the highest levels of ash and protein being 2.07% and 9.65%, respectively. The cookies with powdered artichoke stems (15%) had the greatest overall lipid content (14.65%). Furthermore, the highest total phenolic content, total flavonoid content, and antioxidant activity were found in artichoke by-products (stems and bracts). The panelists approved of up to 15% artichoke by-product powder added to wheat flour. It can be seen from the results that the artichoke by-products are a good source of phytochemicals, minerals, total protein and total lipids, which improves the quality of cookies. Therefore, it can be concluded that using artichoke by-products up to 15% enhanced the antioxidant properties and nutritional value of the baked cookies.

Chemical composition, physical properties, and sensory evaluation of wheat-based cookies enriched with different proportions of corn silk

Incorporating dried corn silk powder (CSP) into food products is considered beneficial for health and suitable for individuals of all ages. Thus, our study is designed to evaluate the effects of adding CSP to prepared cookies as a nontraditional source of dietary fiber and natural antioxidants, focusing on the chemical composition, physical properties, color attributes, antioxidant activity, and sensory properties of fortified cookies. Different CSP proportions (5%, 10%, 15%, and 20%) replaced wheat flour (WF) with a 72% extraction rate. The results revealed that CSP had significant levels of total phenolic content (TPC) and flavonoid content (TFC), measuring 86.42 mg GAE/g and 112.68 mg QE/g, respectively. CSP contained higher quantities of protein and fiber than WF, with values of 14.81 g and 15.21 g per 100 g of flour weight basis, respectively. The amounts of phenolic compounds in cookie samples increased proportionally with the increasing substitution of CSP, while total carbohydrates decreased. Adding CSP at concentrations of 5%, 10%, 15%, and 20% resulted in corresponding increases in crude fiber of 0.52, 1.2, 2.04, and 2.7 times compared to the control cookie samples. As the amount of CSP supplementation increased (0–20%), TPC and TFC in the cookies increased to 3.06 and 4.08 mg GAE/g and 0.02 to 1.28 mg QE/g, respectively. Increasing CSP proportions led to a significant decrease in diameter, thickness, spread factor, volume, and density of fortified cookies. Furthermore, the L* value exhibited a substantial decline from 65.48 to 51.12 as the amount of CSP substitution increased from 5% to 20%. The sensory evaluation characteristics of the cookie samples indicated that the sample with 15% CSP had the highest overall acceptability score. Therefore, this study demonstrates that adding 15% CSP can effectively yield functional cookies without compromising their sensory acceptability.

Formulation of nutritious and functional meal-based biscuits from mixture of soybean, papaya fruit pulp, and baobab fruit pulp flours

Background and objectiveThe current trend in the formulation of convenience foods like biscuits is directed towards using local ingredients endowed with health benefits effects. The present study aimed at valorizing local crops and fruits as substitutes for wheat flour (WF) and sugar in the formulation of healthy, nutritious and functional meal-based biscuits. MethodsSoybean (Glycine max L.), papaya fruit pulp (Carica papaya L.) and baobab fruit pulp (Adansonia digitata L.) flours were produced, characterized, and used to formulate biscuits following a simplex centroid mixing design. The physicochemical, microbiological, sensory and antioxidant properties of the biscuits were assessed. ResultsThe results showed that protein and lipid contents of the biscuits increased significantly (p < 0.05) with the proportion of soybean flour (SF) in the formulation. The significant increase (p < 0.05) in the mineral content of the biscuits was proportional to the incorporation of papaya fruit pulp (PFPF) and baobab fruit pulp (BFPF) flours in the formulation. The energetic value of the formulated biscuits was higher than those made with 100 % WF. The incorporation of SF and BFPF contributed to a significant increase (p < 0.05) in the crude fibres’ content of biscuits. Biscuits made with SF, PFPF and BFPF were safe for human consumption. They were accepted by the panelists; rich in bioactive compounds (total phenolic, flavonoids), and displayed high antioxidant activities. The optimization procedure revealed that the optimum formulation (with the highest desirability of 0.81) was WF 25 g, SF 51.86 g, PFPF 8.06 g and BFPF 15.06 g ConclusionThis study indicates that baobab fruit pulp, papaya fruit pulp and soybean flours can be used as a substitute for WF in the formulation of functional biscuits. Significance of the researchThis study suggests that the formulated meal-based biscuits might have the potential to be used to fight/prevent malnutrition and cardiometabolic diseases, and to boost the immune system while reducing the dependence on wheat.

Functional Cyperus esculentus L. Cookies Enriched with the Probiotic Strain Lacticaseibacillus rhamnosus SL42.

This study presents for the first time functional cookies for diabetics made with 100% organic Cyperus esculentus L. flour, either plain or enhanced with 5% polyfloral honey syrup containing the probiotic strain Lacticaseibacillus rhamnosus SL42. The flour's chemical composition and rheological and functional properties were analyzed, and 33 diabetic and semi-naive panelists assessed the cookies' sensory properties. MRS-cys agar cultures and SEM analysis evaluated SL42 survival and adhesion capacity over 21 days at 25 °C. Results showed that the flour and its extracts are rich in polyphenols and flavonoids, indicating strong antioxidant and antibacterial properties. Both cookie types met international standards when compared to commercial cookies and had similar physical properties. Sensory evaluation on day 1 revealed higher quality indicators for honey syrup-enriched cookies, but after 15 days, control cookies were preferred. The CIE LAB analysis confirmed the dietetic flour's typical dark color, with honey syrup-enriched cookies being darker. Despite textural differences, both cookies maintained detectable crispness over storage. Honey syrup-enriched cookies effectively carried L. rhamnosus SL42, remaining viable at 6.43 Log CFU per cookie after 21 days and adhering to the cookie's surface, as confirmed by SEM analysis. Further research is recommended to better understand the therapeutic value of these cookies.

Preparation of water-soluble dietary fiber from bamboo shoots by fungi fermentation and its supplementation in biscuits

Expanding the utilization of bamboo shoots is extremely meaningful in China because of the high output every year. In this study, the bamboo shoot powder was used as a substrate to produce water-soluble dietary fiber (WSDF) by fermentation with a screened fungi strain Trichoderma dorotheae MLG23, and the prepared WSDF was utilized in the production of biscuits. The bamboo shoots and their residues, WSDF, and biscuits were analyzed on Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), inductively coupled plasma mass spectrometry (ICP-MS), and texture analyzer. The results showed that the fungi exhibited a strong ability to express extracellular cellulase. The enzymatic activities of filter paper activity (FPA), cellobiohydrolase (CBH), and ꞵ-glucosidase (BG) secreted by the strain showed the highest at 50 °C, reaching 0.13, 0.19, and 1.20 U/mL, respectively, and the highest enzymatic activity of endoglucanase (EG) with 0.37 U/mL was obtained at 60 °C. The highest WSDF yield of 45.97 wt% was obtained under the fermentation conditions of bamboo shoot loading 30 g/L, strain inoculum 1010 CFU/L, and fermentation time 4 d at 30 °C. The cellulose and hemicellulose in bamboo shoots were partially utilized by the fungi to produce WSDF. The main metal elements in WSDF were Mg, K, Ca, and Zn. The hardness, cohesion, chewiness, resilience, and adhesion of the biscuits showed a gradual decrease with the increase of WSDF addition in the range from 0 to 10 g per 100 g of low gluten flour. The incorporation of WSDF disrupted the network structure of the gluten, leading to the reduction of some textural properties and the change of microstructure. These results showed a potential utilization of bamboo shoot in production of WSDF and functional biscuits.

Improvement of Antioxidant Activity and Sensory Properties of Functional Cookies by Fortification with Ultrasound-Assisted Hot-Air-Drying Blackberry Powders.

In response to the global challenge of food wastage and high perishability of blackberries, this study evaluated the use of ultrasound-assisted hot air drying (US-HAD) to convert downgraded blackberries into powders, comparing it with traditional hot air drying (HAD). US-HAD reduced the drying time and achieved a final moisture content of 12%. Physicochemical analyses (colourimetry, total soluble solids, titratable acidity, and total phenolic content) were conducted on fresh fruit, powders, and fortified cookies. US-HAD cookies exhibited promising antioxidant activity, with ABTS values ranging from 8.049 to 8.536 mmol TEAC/100 g and DPPH values from 8.792 to 9.232 mmol TEAC/100 g, significantly higher than control cookies. The TPC was 13.033 mgGAE/g in HAD cookies and 13.882 mgGAE/g in US-HAD cookies. UHPLC-ESI-MS analysis showed an increase in phenolic compounds content in fortified cookies compared to the control. Sensory analysis highlighted a superior blackberry flavour and overall acceptability in US-HAD cookies, with statistical analysis confirming their superior nutritional and sensory qualities. Integrating US-HAD blackberry powder into cookies helps reduce food waste and enhances the nutritional profiles of baked goods, offering functional foods with health benefits. This work provides a scientific basis for developing enriched functional cookies, offering a healthy and sustainable alternative for utilising damaged fruits.

Nano-encapsulation of epigallocatechin gallate using starch nanoparticles: Characterization and insights on in vitro micellar cholesterol solubility.

The present work investigates the in vitro cholesterol reduction bioactivity of epigallocatechin gallate (EGCG) prior to and after nano-encapsulation using potato starch nanoparticle (SNP) as wall material. EGCG encapsulation in potato SNPs was achieved through a green inclusion complexation method. The encapsulated EGCG was characterized for its morphology, thermal, and crystalline properties using FESEM, DSC, XRD, and Fourier transform infrared (FTIR) studies. The bioactivity of EGCG to reduce gut cholesterol was studied using in vitro micellar cholesterol solubility study. The encapsulated EGCG exhibited enhanced thermal and crystalline properties. The FESEM results indicated successful nano-encapsulation of EGCG at 20-120nm diameter. The melting point enhanced from 225.7°C in EGCG to 282.9°C in encapsulated EGCG. The crystallinity also enhanced and could be observed through the increased intensity in the encapsulated EGCG. The FTIR results affirmed a shifting of peaks at 3675, 2927, 1730, and 1646cm-1, which corresponds to formation of new H bonds and confirms successful encapsulation of EGCG in SNPs. Further, EGCG had significantly reduced the cholesterol concentration by 91.63% as observed through the in vitro micellar inhibition study. The encapsulated EGCG was not able to reduce cholesterol as observed in the in vitro micellar cholesterol solubility study. This effect occurred due to the unavailability of EGCG after it formed a complex with SNPs. PRACTICAL APPLICATION: This study first investigates the utilization of newly synthesized potato starch nanoparticles as a coating material for nano-encapsulation of EGCG. The enhanced thermal and crystalline properties of these nanoparticles contribute to improved attributes in the nano-encapsulated EGCG. Such properties hold promise for applications in functional food matrices subjected to high-temperature processing, including functional cookies, bread, and cakes. Furthermore, this research explores the bioactivity of EGCG concerning its capacity to reduce gut cholesterol levels. It also examines the potential application of nano-encapsulated EGCG in lowering gut cholesterol through a micellar solubility study.

The objective of the study was to formulate functional cookies enriched with oyster mushroom and to monitor the impact of enrichments on organoleptic attributes, nutritional composition, and shelf-life studies. Three different level i.e., 3 %, 5 % and 7 % of incorporation of oyster mushroom were formulated and organoleptic evaluation was carried out while comparing with control (C- without oyster mushroom). Among them, 3 % (C1) showed the highest score of overall acceptability (8.3 ± 0.69) and it was analyzed for nutritional composition along with the control cookie (C). Enriched cookies possessed higher nutritional profile in comparison to control cookies in terms of protein, fiber, vitamin D, folic acid as well as minerals such as iron, calcium, zinc, and magnesium. Antioxidant activities were found to be 33.23 % and 1.78 umol in terms of DPPH and FRAP assays, higher than control cookies.The total number of bacterial colonies in aluminium ziploc bag were lower than the rest of packaging materials after one month of storage.Hence, it can be concluded that formulated mushroom cookies showed compositional, functional and high nutritional properties and can be stored for a month with minimum growth of microbial activity.

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.

Effect of vitamins and zinc fortification on sensory properties and nutritional value in a functional biscuit

Abstract Biscuits are a popular baked food product known for their extended shelf life. Fortification with essential vitamins and minerals becomes imperative to enhance their nutritional values. This study aimed to enrich a functional biscuit with key nutrients, including vitamins C, D, and E, as well as the mineral zinc. A sensory parameter was examined by performing 9 point-hedonic scales for color, aroma, taste, and overall liking test, showing 1 as the lowest liking score, and 9 as the highest liking value. Proximate, vitamins and mineral analyses were performed to study the macro- and micronutrient content of the biscuits. The findings demonstrated that fortification with vitamins and minerals did not significantly alter the sensory attributes of the functional biscuit (P &gt;0.05). This study found that color, aroma, taste, and overall impression exhibited trivial variations (P &gt;0.05)) between the original and fortified biscuits, with scores of 5.55 vs. 5.50, 6.68 vs. 6.59, 6.09 vs. 5.95, and 6.18 vs. 6.00, respectively. Importantly, the study effectively increased the nutritional content of the biscuit through fortification per serving size of 35 g, 0.00 vs 2.36 mcg, 0.95 vs 5.84 mg, 0.00 vs 39.31 mg, and 0.90 vs 7.47 mg for vitamin C, D, E, and zinc, respectively. This study also showed the total energy, protein, carbohydrate, and fat content for each serving size of the original and fortified biscuits, resulting in 160.01 vs 161.92 kcal, 2.69 vs 2.67 g, 21.11 vs 21.70 g, and 7.20 vs 7.16 g, respectively. In conclusion, fortifying vitamins and zinc in the functional biscuit effectively heightened its nutritional profile of vitamins and minerals, while sensory properties remained largely unaffected.

Crumbling Cookie Categories: Deconstructing Common Cookie Categories to Create Categories that People Understand

Users of online services often encounter cookie banners that ask them to consent to different categories of cookies. Frequently, these categories are labelled using the four categories defined by the 2012 Cookie Guide from the UK's International Chamber of Commerce (ICC). However, prior research suggests that users have difficulty understanding what these category labels actually mean. We conducted a four-part study to identify labels that more intuitively convey the four cookie categories. First, we crowd sourced new category labels. We then evaluated users' comprehension and sentiment towards the labels in a series of surveys focused on definitions and hypothetical scenarios. Finally, we selected a new slate of category labels based on the results of the prior surveys, and conducted a between-subjects, online behavioral experiment to compare the new slate with the original labels. We ultimately recommend that the industry adopt the category label ``anonymous analytics cookies'' in lieu of the term ``performance cookies'' and ``extra functionality cookies'' instead of ``functional cookies.'' Adopting our recommended terms would both improve the usability of current cookie consent interfaces and any future privacy consent mechanisms that use the same categorization. We also recommend revisiting the categories themselves as the distinctions between these categories do not seem to be well understood and may not reflect useful distinctions for privacy decision making.

Functional Biscuits, a Healthy Addition to Your Coffee Break-Evaluating Consumer Acceptability and Willingness to Pay.

An increasing number of individuals are eating out due to work and study commitments. This trend directly influences people's food choices, especially those who frequently rely on snacks and pre-packaged foods. Consuming these foods can lead to long-term health consequences. Adding functional foods to vending machines could lead to healthier choices. Our aim is to evaluate the acceptability and willingness to pay (WTP) of workers and students for a snack pack of novel functional biscuits (FBs) made with high amylose contents. We found that the experimental flour used is effective in preventing various non-communicable diseases; two phases of analysis were carried out on 209 participants. The participants blindly tested the products and only after the sensory evaluation were they informed about the biscuits' health contents. Firstly, the blind investigation highlighted the acceptability of the FBs compared to the conventional biscuits. Secondly, the finite mixture model on WTP revealed that some consumers are interested in the health benefits associated with high-amylose test blends and others are focused on hedonistic taste. The design of a communication strategy and industry approach should aim to assist consumers in comprehending the health benefits and sensory aspects of novel functional foods available on the market.

Development of Sustainable Vegan Pea Protein-Zinc Complex: Characterization, In Vitro Cellular Mineral Uptake, and Application in Functional Biscuit Production

This study aimed to investigate the potential of pea protein concentrate (PPC) to form protein-mineral composites, with a specific focus on its zinc- (Zn-) binding capabilities. In addition, the physical and functional properties of PPC were evaluated. PPC, a potential protein source, was found to possess lipophilic properties, suggesting its suitability for various applications in food production. The investigation involved a comprehensive characterization of pea protein concentrate-zinc complex (PPC-Zn) composites, utilizing various analytical techniques such as Fourier transform infrared spectroscopy, scanning electron microscopy, particle size analysis, zeta potential measurement, and thermogravimetric analysis. The findings of this study indicated that the protein content of PPC-Zn (79.02 ± 1.33%) insignificantly increased as compared to PPC (78.86 ± 1.16%). Furthermore, PPC demonstrated improved functional properties, including increased protein solubility (2.55%), enhanced water-holding (13.09%) and oil-holding capacity (11.17%), and improved foaming capacity and stability (2.08% and 6.07%, respectively). These improvements in functional properties were likely attributed to the unique surface structure observed in SEM micrographs. The research also highlighted the maximum binding capacity of PPC for zinc, which was observed at concentrations of 5 mM (95.35 ± 1.86%). This binding of zinc ions to PPC induced changes in the characteristics and internal structures of the protein concentrate. Notably, the presence of functional groups such as -COOH, -OH, and –NH2 in PPC suggested their involvement in coordinating with zinc ions to form PPC-Zn composites. This investigation demonstrated a significant increase (2.26%) in the mineral bioavailability of PPC-Zn. Additionally, the cellular uptake, retention, and transport of PPC-Zn were improved by 9.79%, 7.84%, and 9.51%, respectively. Fortified biscuits (B2) demonstrated enhanced cellular uptake (2.79%), retention (4.84%), and transport (3.51%) compared with control biscuits. Fortified biscuits (B2) had higher microbial counts (total plate count is 3.57 ± 0.03 and the yeast-mold count is 3.96 ± 0.07 cfu/g) than control biscuits (B1) (total plate count is 2.49 ± 0.13 and the yeast-mold count is 3.44 ± 0.11 cfu/g) at the end of storage, and there is no difference in sensory evaluation between the control and fortified biscuits. Furthermore, the key findings indicated that PPC could serve as a promising carrier for mineral supplements, binding with zinc effectively.
