Summary
Diabetic-friendly cookies made with organic tiger nut flour offer antioxidant benefits. Enriched cookies initially rated higher but control versions were preferred long-term, with the probiotic surviving storage.
Area of Science:
- Food Science
- Nutritional Science
- Microbiology
Background:
- Developing functional foods for diabetic management is crucial.
- Tiger nut (Cyperus esculentus L.) flour offers potential due to its nutritional profile.
- Incorporating probiotics into food matrices presents challenges for viability and stability.
Purpose of the Study:
- To create and evaluate functional cookies for diabetics using organic tiger nut flour.
- To assess the impact of polyfloral honey syrup with Lacticaseibacillus rhamnosus SL42 on cookie properties.
- To determine the antioxidant, antibacterial, and sensory characteristics of the developed cookies.
Main Methods:
- Chemical, rheological, and functional analyses of tiger nut flour.
- Sensory evaluation by 33 diabetic and semi-naive panelists.
- Microbiological (MRS-cys agar) and SEM analyses for probiotic survival and adhesion.
- CIE LAB color analysis and physical property assessment.
Main Results:
- Tiger nut flour exhibits rich polyphenol and flavonoid content with antioxidant and antibacterial properties.
- Both cookie types met international standards; honey-enriched cookies initially scored higher sensorially, but control cookies were preferred after 15 days.
- Lacticaseibacillus rhamnosus SL42 remained viable (6.43 Log CFU/cookie) and adhered to the surface of honey-enriched cookies after 21 days.
Conclusions:
- Functional cookies for diabetics can be successfully produced using organic tiger nut flour.
- Honey syrup enrichment supports probiotic viability and adhesion, though long-term sensory preference favors control cookies.
- Further research is needed to explore the therapeutic potential of these functional cookies.

01:29Microbes in Food Production
Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...
01:27Microbes in the Production of Fermented Foods
Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
01:22Probiotics
Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...
01:22Bioreactor Controls-III
Strain improvement is a foundational strategy in industrial microbiology aimed at maximizing microbial productivity, particularly because natural isolates typically yield commercially valuable products in very low concentrations. Although optimizing the culture medium and environmental conditions can improve yields, these adjustments are inherently limited by the organism’s genetic potential. As a result, the focus shifts toward genetic modifications to enhance biosynthetic capacity. The...
01:25Production of Organic Acids
Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...
01:27Microbiota of the Large Intestine
The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...
