Abstract
Purpose
The purpose of the present study was to plan with the objectives to optimize and find out the best level of texturized protein from sunflower, soybean and flaxseed on the basis of quality and overall acceptability of the cookies.
Design/methodology/approach
Defatted meal from sunflower, soybean and flaxseed was texturized using extruder. Texturized defatted meal of sunflower, soybean and flaxseed was blended at 10, 20, 30 and 40 per cent levels with wheat flour for making cookies using standard procedure.
Findings
Functional properties such as water absorption index, foaming capacity and protein digestibility were increased, while water solubility index and fat absorption capacity decreased with increased levels of texturized defatted meal in wheat flour. Spread ratio, sensory, colour and overall acceptability of cookies were negatively affected when level of texturized flour increased as compared with the control. The force required for breaking cookies decreased with increased level of texturized defatted meal of sunflower, soybean and flaxseed incorporation. Cookies with 10 per cent texturized sunflower, soybean and flaxseed flour received the highest sensory scores. The result showed that texturized defatted meals serve as good substitute to wheat flour with increased protein content in cookies production and utilization.
Originality/value
The study demonstrated that deoiled cake, a byproduct obtained from sunflower, soybean and flaxseed oil industry, offers great potential for supplementation of proteins in food products.

The purpose of the paper is to study the effect of the gliadin and glutenin fractions of gluten on the cookie quality.
Abstract
Purpose
The purpose of the paper is to study the effect of the gliadin and glutenin fractions of gluten on the cookie quality.
Design/methodology/approach
Ten different wheat varieties were analyzed for the flour physicochemical characteristics, gluten composition and rheological properties. The different flours were baked into cookies. The cookies were analyzed for spread ratio and texture. Relationships of various flour parameters, gluten composition and cookie characteristics were determined.
Findings
Gluten subfractions, damaged starch, protein, AWRC values were significantly correlated to the cookie spread and texture. Damaged starch (r=−0.638), protein (r=−0.508) and AWRC (r=−0.844) had a negative relationship with the cookie spread. The flours with higher SDS sedimentation value also produced cookies with lower spread ratio and harder texture. The study clearly demonstrated a positive correlation between Gli:Glu ratio (r=0.765) and spread ratio and a negative correlation (r=−0.528) with hardness of the cookies measured in terms of breaking force. Flours with lower dough development time and dough stability performed better as cookie flours.
Originality/value
The gliadins and Gli/Glu ratio had a significant effect on the cookie spread and texture and the prediction equation developed during the study could accurately predict the cookie spread from the Gli/Glu ratio and AWRC values.

The purpose of this study is to evaluate the quality and sensory properties of cookies produced from wheat flour using avocado puree as fat substitute.
Abstract
Purpose
The purpose of this study is to evaluate the quality and sensory properties of cookies produced from wheat flour using avocado puree as fat substitute.
Design/methodology/approach
Cookies were produced from wheat flour using avocado puree as fat substitute in ratio 0%, 25%, 50%, 75% and 100%, respectively. The formulation of margarine and avocado puree blends was done by using D-Optimal Mixture Design. In all, 20 samples were produced from each substitution level and analyses were done in triplicates to obtain mean values using standard methods. Means were separated by Duncan’s multiple range test, and significances were accepted at less than 5% confidence level (p < 0.05). Proximate and functional analyses were conducted on the flour samples, while cookie samples were subjected to proximate and sensory analyses.
Findings
The results of this study revealed that the values of loose bulk density, packed bulk density, oil absorption density, water absorption capacity, swelling power, solubility and dispersibility of the flours at p < 0.05 are 0.3–0.4 g/ml, 0.5–0.7 g/ml, 16.9%–94.0%, 39.7%–80.6%, 461.2%–618.2%, 6.0%–29.8% and 69.0%–82.8%, respectively. The moisture, protein, fat, total dietary fiber, total ash and carbohydrate contents of the cookies at p < 0.05 are 3.6%–16.7%, 6.5%–9.9%, 2.5%–19.2%, 1.7%–1.9%, 1.1%–3.0% and 65.0%–70.7%, respectively. The taste, color, crispiness, texture and overall acceptability of the cookies at p < 0.05 are 7.4–7.8, 6.9–7.5, 7.2–7.9, 7.3–7.7 and 7.4–8.3, respectively. The sensory scores showed that panelists preferred the taste, crispiness and texture of the cookies produced from wheat flour using avocado puree as fat substitute at varying proportion. The sensory characteristics of sample WF4 (100% avocado puree) were rated overall best in all the parameters tested followed by sample WF3 (75% avocado puree). Hence, this study established the possibility of producing cookies from wheat flour using avocado puree as fat substitute without a negative impact on the sensory characteristics and the consumers’ acceptability.
Practical implications
The cookies produced from this study are not meant for vegetarians because eggs were added in the formulations and recipes but could be valuable to ovo-vegetarians that may take food with eggs without restriction. The major challenge of this study was that avocados are very expensive in much of the world, so this is only suitable and viable where there is an excess of the fruit.
Originality/value
This study examined the use of avocado puree as fat substitute in cookie production. Effects of avocado puree on proximate composition and functionality of cookies produced from wheat flour were also determined. This approach was novel, and it will encourage the use of avocado for value-added in industrial food production.

Abstract
Purpose
This study aims to assess the quality characteristics and acceptability of cookies from sweet potato–maize flour blends and to determine nutritional quality, color and palatability traits and to compare the effects with that of wheat cookies, so as to suggest a cost-effective production method to bakers and retailers. This would ensure food security, enhanced health, combat malnutrition problems and improve the production of the crops.
Design/methodology/approach
Cookies were prepared by the method reported by Okaka and Isieh (1990), Abayomi et al. (2013), Onabanjo and Ighere (2014) with modification. Flour (200 g) from each sample of different flour blends was used for the experiment. Sugar (80 g) was creamed with margarine (100 g) until light and fluffy constituency was obtained using Kenwood chef with initial minimum speed, and the speed increased stepwise until the mark of 6 on the chef indicator was attained. Whole egg (60 g) was added, then followed by flour (200 g), powdered milk (20 g), baking powder (0.1 g) and salt (1 g) were added and mixed until a stiff paste (batter) was obtained. The batter was rolled on a floured board using a rolling pin to a thickness of 0.2-0.3 cm. The rolled batter was cut into circular shapes with a cutter and arranged on a greased tray and baked at 1500°C for 20 minutes. The cookies were brought out, cooked and packaged in cellophane bag until used for laboratory analysis.
Findings
The results revealed that substitution of sweet potato flour with maize flour significantly (p < 0.05) reduced the protein from 6.8-4.4 per cent, moisture from 5.3-5.0 per cent, crude fibre from 3.4-2.5 per cent and fat from 9.8-8.5 per cent of the composite flours and the cookies. The ash and sugar contents were increased from 4.3-5.8 per cent for ash and 2.1-3.9 per cent for sugar with increase in sweet potato flour substitution. The calorific value of the cookies decreased from 457-397 cal/100 g as the percentage of sweet potato flour increased in the maize flour cookies. Sensory evaluation results showed that the colour, texture, taste and overall acceptability changed significantly (p < 0.05) with increase in sweet potato flour substitution. The optimum substitution level was 40 per cent; above this, the product becomes less acceptable to the consumer.
Research limitations/implications
Fabrication and production processing machines that use sweet potato will be a great challenge.
Originality/value
This research is of value to the bakery industry or retailers. The optimum substitution level of sweet potato flour was 40 per cent, and it appears to be a promising measure from the view of practicability. The relative ease of getting sweet potato flour makes it superior to other imported flour like wheat and in reducing cost of importation of wheat to Nigeria.

Abstract
Purpose
The purpose of this paper was to replace totally the wheat flour for rice flour, whole soy flour and cassava starch in the formulation of chocolate cookies.
Design/methodology/approach
Chocolate cookies with wheat flour, rice flour, whole soy flour and cassava starch were produced, and compared to a commercial chocolate cookie regarding to physical properties and sensory acceptability.
Findings
The chocolate cookie made with rice flour instead of wheat flour was as liked as the cookie with wheat flour, and the greater acceptability scores received by the rice flour cookies correlated with less colour intensity and a lower specific volume thereof. The cookie with cassava starch stood out because of the intensities of its parameters, its more intense colour, and its acceptability scores among the consumers. The cookie with whole soy flour had lower sensory acceptability scores, and the commercial cookie stood out for its high cutting force (instrumental texture).
Originality/value
Celiac consumers desire products with adequate sensory characteristics. This study presents a new gluten-free product, the chocolate cookie made with rice flour, that has the potential to be produced, as this product is as accepted as a cookie made with wheat flour, and even more accepted than a commercial one also made with wheat flour. Therefore, this study offers subsidies for improving the diet of celiac consumers.

Abstract
Purpose
The demand for functional foods has been increasing tremendously throughout the globe and keeping in view the health beneficial properties of apricot fruit. The purpose of this study is to develop wheat flour based cookies enriched with apricot pulp powder in order to improve nutraceutical properties of cookies and dilution of gluten at the same time.
Design/methodology/approach
Cookies were prepared from wheat flour blended with apricot pulp powder at 0, 10, 15, 20 and 25% level and evaluated for proximate, functional, rheological, nutraceutical and sensory properties.
Findings
Fibre content of apricot powder-incorporated cookies (3.23%) was significantly (p < 0.05) higher at 25% level than control (1.64%). The water absorption and oil absorption capacities decreased significantly (p < 0.05) upon increasing level of apricot pulp powder. The ß-carotene content, antioxidant activity and total phenolic content increased significantly (p < 0.05) upon incorporation of apricot pulp powder. The thickness of cookies increased, however, diameter and spread ratio decreased with increase in the levels of apricot pulp powder. Lightness (L*) value decreased, while redness (a*) and yellowness (b*) increased when incorporated with apricot pulp powder. Cookies having 25% apricot pulp powder showed maximum hardness and overall acceptability.
Originality/value
To the best of our knowledge, the scientific literature on incorporation of apricot pulp powder in bakery products is scanty. As such the present research has a tremendous scope for the food industries to produce functional bakery products with antioxidant properties and diluted the gluten content at the same time.

Abstract
Purpose
The paper aims to report the main findings of a study for the Dutch Regulatory Authority for the Telecommunications sector OPTA to explore how the new European “cookie rules” in the ePrivacy Directive impact on behavioral advertising practices via the storing and reading of cookies. The paper identifies the main dilemmas with the implementation of the new European rules. The Dutch case provides a valuable reality check also outside The Netherlands. Even before the amendment of the directive, The Netherlands already had an opt‐in system in place. From the Dutch experience important lessons can be learned also for other European countries.
Design/methodology/approach
After a brief analysis of the legal situation in Europe and in The Netherlands (section 2), section 3 reports about the findings of a survey among the main providers of targeted advertising in The Netherlands to explore the current use of cookies and targeted advertising practices. Section 4 describes the findings of a qualitative survey among Dutch internet users with the goal to define their level of skills and knowledge, acceptance of and behavior towards the placing and reading of cookies. A concluding section (section 5) summarizes the main findings and identifies implications for the future policy debate.
Findings
The results show that the majority of the surveyed parties involved in behavioral advertising do not inform users about the storing of cookies or the purposes of data processing of the subsequently obtained data, neither have they obtained users' consent for the storage of cookies. The authors also found that the majority of users lack the skills and knowledge to handle cookies.
Social implications
The findings critically question the wisdom of the “informed consent regime” that currently lies at the heart of Europe's ePrivacy Directive. The paper concludes with reflections about the concrete policy implications of the study, and a number of concrete suggestions of how to approach the future debate with regard to the regulation of online tracking and cookies.
Originality/value
The approach of the paper is original in that it combines legal analysis with two surveys: one among behavioral advertisers and one among online users. This approach permits us to better understand the efficacy of the new legal rules, to make predictions regarding the level of compliance with the new rules and identify areas in this highly topical debate that require further attention.

Abstract
Purpose
Cookies were not generally viewed as functional contributors to well-being as they are primarily perceived as confectionery products. The purpose of this paper is to evaluate the potential of flaxseed-enriched cookies as carriers of lignans and omega-3 fatty acids – functional compounds that are lacking in the western diet.
Design/methodology/approach
An online questionnaire collected data from Croatian consumers (n=1,035). The majority of the samples were women (73 per cent) in the age range 15-65 years (97 per cent). Most participants were employed, had a higher education degree, and lived in urban areas. Questions examined the consumption of cookies and flaxseed, interest for functional cookies, nutritional knowledge, and awareness.
Findings
Majority of subjects consumed cookies (93 per cent), while 61 per cent did not eat flaxseed or ate it less than once a month. The consumers showed elevated interest for the functional cookies with flaxseed, among which elderly women with higher nutrition awareness, and nutrition knowledge were the most interested. Functional cookies with flaxseed could be used for delivery of lignans and omega-3 fatty acids in everyday diet, but in order to reach wider range of consumers producers might benefit from employing nutritional educational marketing campaigns.
Originality/value
Data from the study decreased scarcity of information on consumer behaviour related to flaxseed consumption and on potential use of cookies as a functional food. Reported findings will be useful to dieticians, food industry, and food researchers in countries with a high prevalence of cookie consumption.

Abstract
Purpose
Over the past decades, there has been a rising trend in the prevalence of non-communicable diseases and their risk factors in Malaysia. Consequently, functional food is gaining interest amongst health-conscious consumers. This study aimed to evaluate the functional potential of cookie enhanced with Strobilanthes crispus (SC) and to evaluate its physicochemical and organoleptic properties.
Design/methodology/approach
Sensory evaluation was carried out using nine-point hedonic and line scales and the ranking test amongst consumer panels (n = 150) to evaluate control, 2, 4 and 6% SC cookies. Preferred formulation and control cookies were then subjected to chemical (moisture, protein, fat, ash, carbohydrate, calcium, sodium and potassium contents) and physical (texture profile and water activity [Aw]) analyses.
Findings
There was no significant difference (p < 0.05) in terms of overall acceptability and ranking scores between control and 2% SC cookies upon gender discrimination. Results indicated that incorporation of 2% SC into cookie caused significant enhancement (p < 0.05) of moisture, fat, ash, calcium and potassium contents but did not cause a significant effect on hardness, although loss of crispiness was observed after two weeks of storage at room temperature. This study showed that the 2% SC cookie did not diminish consumers' acceptance while increasing potassium content. Most notably, it can be declared as a source of calcium.
Originality/value
This original research features the incorporation of medicinal plant SC in the development of novel functional cookie and the results constitute unique findings pertaining to its nutritional contents. Remarkably, the findings of this research have contributed knowledge to existing literature as well as benefits food manufacturers in creating nutritious functional cookie to better meet the needs and expectations of consumers, healthcare providers, governmental organisations and consumer advocacy groups while maintaining health benefits without compromising consumers' acceptance.
