As a direct consequence of understanding the importance of the relationship between health and food, the interest in healthy recipes has increased. In the present study, wheat flour was used to replace chia seed (CS) in the cracker formulation (control) at levels of 10, 20, and 30% (w/w) and fat content was reduced by 25, 50, and 75% for the production of low-fat crackers. The physicochemical, textural, sensorial properties of the crackers were investigated. It was determined that CS had high a dietary fiber (38.7%), protein (21.78%), and fat (28.69%) content. The cracker sample containing 25% fat and 30% chia seed had the highest amounts of protein (14.49%) and dietary fiber (16.70%). CS could provide positive effects on health in terms of its high fiber content and low carbohydrate value. Six different fatty acids (FAs) were determined in the cracker samples. By reducing fat and increasing chia seed amount; oleic, linoleic, α-linolenic increased compared to the control sample, whereas the palmitic acid amount decreased significantly. According to the sensorial evaluation, the crackers were acceptable. It was also determined that CS was a suitable supplementation for low-fat products.
The aim of this study was to analyse the production of gluten-free, low protein cookies, which can easily be consumed by celiac and phenylketonuria (PKU) patients. The formula was adopted to prepare the control cookies (without dried fruits) from maise starch, stabilisers, salt, sodium bicarbonate, protein-reduced milk powder, and sunflower oil. Different cookies were made by adding raisins (R), dried black currants (Cu), dried dates (D), dried apples and cinnamon (A) separately. In cookies, two different stabilisers were calculated according to starch weight [pectin (P): 0.15%, glycerol monostearate (GMS, G): 0.4%]. The effects of stabilisers and dried fruits on the physicochemical and sensory properties of cookies were investigated. The protein content was significantly higher (P < 0.05) in the cookies including R with pectin (PR), Cu with pectin (PCu), and A with pectin (PA). The amount of phenylalanine (Phe) was significantly higher (P < 0.05) in PR. The values of dietary fibre were the highest in the A cookies, while the lowest values appeared in the control (C). In the sensory evaluation (appearance, tasting properties, and affordability), it was found that PD (pectin with dries dates) was chosen as the best cookie (P < 0.05).
Although having functional properties, fat is known to be adversely effective in case of high consumption. High fat consumption causes health disorders such as obesity, cardiovascular diseases and high blood pressure, insulin balance disorders and cancer. For this reason, it is important to reduce fat consumption and create food formulations rich in bioactive components. In the scope of this study, CS (Chia seed) was replaced with wheat flour 10%, 20%, and 30% (w/w) and the fat amount was decreased in 25%, 50%, 75% (w/w) ratios for formulating low-fat crackers, and the antioxidative potential of the samples was evaluated. Extractable, hydrolysable, bioaccessible phenolic fractions of samples were analyzed in terms of TEAC ABTS , TEAC CUPRAC , TEAC DPPH and Total Phenolic Content (TPC) (Folin Ciocalteu's method). CS replacement was determined to be more effective than a fat reduction on AC and TPC results of samples. By 25, 50 and 100% fat reduction of extractable, hydrolysable and bioaccessible phenolic fractions, TEAC ABTS values increased respectively as 5.87%, 9.33% and 12.11%. 75% fat reduced-30% CS supplemented sample was 91.0% higher than 100% fat including-30% CS supplemented sample and 143.4% higher than the control sample in terms of TEAC ABTS for bioaccessible phenolic fractions. The dietary fiber, protein content and fatty acid composition are thought to be effective in the potential of CS. It is proved that CS could be expressed as a convenient pseudo-cereal for functional food formulations.
