Abstract

Gluten-free foods have gained substantial attention due to the increasing prevalence of gluten intolerance, coeliac disease, and a growing consumer preference for functional and health-orientated bakery products [1, 2]. Cookies are one of the most widely consumed bakery items; however, conventional cookies are primarily based on wheat flour, which contains gluten and is unsuitable for gluten-sensitive individuals [1, 3]. The present review titled “Gluten-Free Cookies: Taste the Freedom” focuses on the formulation, nutritional significance, and functional attributes of gluten-free cookies developed using alternative cereals, millets, and natural ingredients [3, 4]. Special emphasis is placed on the use of ragi (finger millet), jowar, barnyard millet, gram flour, flax seeds, cocoa powder, dates, jaggery, and nuts as gluten-free substitutes [3, 5]. These ingredients not only eliminate gluten but also enhance dietary fibre, mineral content, antioxidant potential, and overall nutritional quality [4, 5]. The review discusses formulation strategies, the role of individual ingredients, processing considerations, and quality attributes such as texture, taste, and consumer acceptability [3, 4]. The use of natural sweeteners and plant-based ingredients further aligns gluten-free cookies with current trends in clean label and functional foods [2, 3]. This review highlights the potential of gluten-free cookies as a nutritious, safe, and palatable alternative to traditional bakery products, supporting their growing role in health-focused food markets [1, 4].

Introduction

Gluten is a composite protein mainly found in wheat, barley, and rye, responsible for the viscoelastic properties of dough ^[6]. While gluten contributes to the structure and texture of bakery products, its consumption can cause adverse health effects in individuals suffering from coeliac disease, gluten sensitivity, or wheat allergy ^[7]. The global increase in gluten-related disorders has driven the demand for gluten-free food products, particularly bakery items such as cookies, biscuits, and bread ^[8]. Cookies are popular across all age groups due to their convenience, taste, and extended shelf life ^[9]. Developing gluten-free cookies poses technological challenges because the absence of gluten affects dough handling, texture, and sensory quality ^[10]. To overcome these challenges, alternative raw materials such as millets, legumes, and oilseeds are increasingly being explored ^{[8, 10].} Millets like ragi, jowar, and barnyard millet are naturally gluten-free and nutritionally superior, being rich in dietary fibre, minerals, and bioactive compounds ^{[6, 8].} The objective of this review is to evaluate the potential of gluten-free cookies formulated using millet-based flours and natural ingredients, highlighting their nutritional benefits, formulation strategies, and role in promoting health and dietary inclusivity ^{[9, 10].}

What are Functional Cookies

Functional cookies are enriched bakery products containing ingredients that provide health benefits beyond basic nutrition, such as improving digestion, boosting immunity, and supporting metabolic health. ^[11]

Characteristics of Functional Cookies

What Is Gluten?

Gluten is a collective term for a group of seed storage proteins primarily found in certain cereal grains, especially wheat, barley, and rye. Chemically, gluten consists of two major classes: prolamins (such as gliadin in wheat, hordein in barley, and secalin in rye) and glutelins. [23]

Non-celiac gluten sensitivity ^[24]
Wheat allergy ^[25]
Dermatitis herpetiformis (DH) ^[26]

Why Gluten Intolerance Is Increasing Today

? Modern Wheat Has Higher Gluten Content ^[27]

? Excessive Consumption of Wheat Products ^[28]

? Poor Gut Health Due to Lifestyle ^[29]

? Highly Processed Wheat Products ^[30]

Preparation of Gluten-Free Cookies

? Date Paste Preparation

Dates are cleaned, briefly soaked in warm water, and blended to obtain a smooth paste.
The paste is kept aside for later use.

? Ingredient Mixing

Dry Ingredients
- Ragi, varai, jowar, and gram flour are combined with baking powder and baking soda.
- The mixture is sieved to achieve uniform distribution and remove lumps.
Wet Ingredients (Creaming)
- Soft butter or ghee is beaten with jaggery powder until light and fluffy.
- Date paste is incorporated to form a smooth, evenly mixed base.
- Care is taken to avoid over-mixing for proper cookie texture.

? Dough Formation

The dry mixture is gradually folded into the wet mixture using gentle strokes.
Small amounts of milk are added only as needed to bind the dough.
The final dough should be soft, pliable, non-sticky, and free from cracks.
Dough is rested briefly to allow moisture absorption and improve handling.

? Shaping

The work surface is lightly dusted with flour.
Dough is rolled evenly to a medium thickness suitable for cookies, ensuring consistent texture.

? Cutting

Cookie shapes are cut using a cutter or suitable mold.
Excess dough is gathered, re-rolled, and reused.

? Baking

The oven is preheated, and cookies are arranged on a lined baking tray with spacing.
Cookies are baked until edges are lightly browned and the base is set.
After baking, cookies are cooled first on the tray, then on a wire rack to firm up.

? Packaging and Storage

Completely cooled cookies are stored in airtight containers or food-grade pouches.
Products are kept in a cool, dry environment to maintain quality and shelf life.
All dry ingredients were weighed accurately and mixed uniformly. Butter and jaggery were creamed until light and fluffy, followed by the addition of milk and date paste. The dry ingredient mixture was gradually incorporated to form uniform dough. The dough was sheeted, cut into desired shapes, and baked in a preheated oven at 170–180°C for 12–15 minutes. The baked cookies were cooled at room temperature and stored in airtight containers for further evaluation.

The prepared gluten-free cookies were evaluated for physical, sensory, and nutritional parameters. Physical parameters included weight, diameter, thickness, and spread ratio. Sensory evaluation was carried out using a 9-point hedonic scale by a semi-trained panel. Nutritional composition was estimated based on standard food composition data.

RESULTS AND DISCUSSION

The present study focused on developing gluten-free, fiber-rich cookies using ragi (finger millet) and varai (barnyard millet), which are naturally gluten-free and high in dietary fiber ^[52,53]. Incorporation of these millets significantly enhanced the fiber content, improving nutritional quality and supporting digestive health, glycemic control, and satiety ^[54,55].Despite the absence of gluten, satisfactory dough binding and structural stability were achieved due to the starch and fiber components of millets, along with gram flour and flax seeds ^[56,57].The cookies exhibited desirable texture, color, and sensory acceptability ^[58].Overall, the study demonstrates the potential of ragi and varai in producing nutritious, acceptable gluten-free cookies ^[59].

Sensory evaluation showed good acceptability in terms of appearance, flavor, taste, texture, and overall quality ^[60]. The characteristic flavor of millets was balanced through appropriate ^[58,60]. The proximate analysis of the developed gluten-free, fiber-rich cookies revealed a nutritionally balanced product with enhanced functional properties ^[61] .Moisture content decreased from 7.0% before baking to 4.0% after baking, which is desirable for improved shelf stability and crisp texture ^[62].Reduced moisture also contributed to the concentration of macronutrients in the baked cookies ^[63].

Ash content increased slightly after baking, indicating a higher mineral density, primarily contributed by ragi, barnyard millet, gram flour, and flax seeds ^{[53, 64]}. Fat content increased marginally due to moisture loss, with butter, flax seeds, and nuts acting as major lipid sources ^{[61, 65].}Protein level of 9.1% was observed in the cookies, largely due to the presence of millets, gram flour, nuts, and milk, highlighting their nutritional advantage over traditional cookies.^{[56, 59]}.

Crude fiber content increased to 8.0% after baking, highlighting the functional value of ragi, barnyard millet, flax seeds, and dates ^{[54, 55]}. High fiber content is associated with improved digestive health, glycemic regulation, and enhanced satiety, making the product suitable for health-conscious consumers and individuals with gluten intolerance ^{[52, 54]}.

Carbohydrate content remained the major macronutrient, mainly derived from millets and jaggery, while the calculated energy value of 404 kcal/100 g indicates that the cookies provide sufficient energy along with improved nutritional quality ^{[61, 65]}. Overall, the results demonstrate that the formulated cookies successfully combine gluten-free characteristics with high fiber and acceptable macronutrient composition, supporting their potential as a functional bakery product ^{[59, 60]}.

Parameter	Before Baking	After Baking (%)
Moisture	7.0 ± 0.2	4.0 ± 0.2
Ash	2.2 ± 0.1	2.4 ± 0.1
Fat	12.0 ± 0.3	12.8 ± 0.3
Protein	8.5 ± 0.2	12.8 ± 0.3
Crude Fiber	7.5 ± 0.2	8.0 ± 0.2
Carbohydrate*	62.8	63.7
Energy (kcal/100 g)	62.8	404

Sensory evaluation revealed that the cookies scored well for taste, texture, and overall acceptability, attributed to the use of cocoa powder, nuts, and natural sweeteners.

Sensory Evaluation Scores (9-Point Hedonic Scale)

Overall Acceptability	8.5

CONCLUSION

Gluten-free cookies formulated using millets and natural ingredients present a promising alternative to conventional wheat-based bakery products ^{[60, 61]}. The combination of ragi, jowar, barnyard millet, and functional ingredients not only addresses gluten-related health concerns but also enhances nutritional quality ^[62,63]These formulations align with the growing demand for functional, clean-label, and health-oriented foods ^[64,65]. Gluten-free cookies truly represent the concept of “Taste the Freedom” by offering safe, nutritious, and enjoyable options for gluten-sensitive consumers ^[61,66].

This study established the feasibility of producing gluten-free, fiber-enriched cookies using ragi, barnyard millet, and complementary natural ingredients ^[62,67]The developed cookies showed uniform physical properties, an acceptable spread ratio, and a pleasant texture, even in the absence of gluten ^[68]. The functional role of gram flour and flax seeds was evident in improving dough cohesiveness and overall product structure ^[69,70].

Nutritional evaluation revealed an improved profile, characterized by higher dietary fiber, adequate protein and fat levels, and enhanced mineral content ^[63,71]. The reduction in moisture after baking supported better crispness and storage stability ^[72]. Sensory analysis indicated strong acceptance for taste, flavor, texture, and overall quality, largely due to the inclusion of cocoa powder, nuts, dates, and jaggery ^[73,74].

In conclusion, millet-based gluten-free cookies can serve as a nutritious and appealing alternative to traditional wheat cookies, with promising potential for application in health-oriented and gluten-free food products ^[60,64,75].
