dc.description.abstractSix antioxidant rich bars were developed using puffed wheat (30g), peanut (10g) and honey (15g) as a base materials. Flaxseed and chiaseed were then separately incorporated in the bars with different levels. In the second standardization three fruits namely mango, apple and guava were individually incorporated in different proportion to the highly acceptable level of flaxseed and chiaseed bars. The incorporation of flaxseed and chiaseed was found to be acceptable at 5g and whole mango, apple and guava fruit was acceptable at 10g, 5g and 5g respectively. The raw ingredients, control bar and acceptable bars were analyzed for physical parameters and nutritional composition to analyze the effect of incorporation of antioxidant rich components. A significant (p<0.01, p<0.05) difference was observed in terms of proximate composition among the developed bars. The micronutrient content such as calcium, iron, vitamin C, β-carotene and bioactive components such as total phenols, flavonoids and tannins were significantly increased (p<0.01). Sugar, starch, in-vitro starch digestibility and in –vitro iron digestibility decreased while anti-nutrients increased in the acceptable bars. The antioxidant activity in the bars increased significantly (p<0.01), and mango-chiaseed bar was found to have highest activity of DPPH (80.09 per cent), FRAP (480.40 µmolFe2+/g), ABTS (45.49 mmolTE/55g) and RPA (222.92 mg TE/55 g). The shelf life study revealed that the acceptable bars stored in metalized polyester films had good quality attributes in terms of sensory properties, moisture content, free fatty acid value and microbial quality. To study the impact of supplementation of developed bars, 60 hyperlipidemic subjects in age group of 35-55 years were selected from the hospitals of Ludhiana and Jaipur City respectively. The subjects of experimental group were supplemented with one bar (55g) daily for 90 days. In experimental group of both the cities a significant increase (p<0.01) in intake of fruits and other vegetables were observed. Among the nutrient intake significant increase (p<0.01) in consumption of fibre, fat, calcium, iron, zinc, riboflavin, niacin, vitamin C and β-carotene was observed after supplementation. In Ludhiana and Jaipur City significant decrease in weight of experimental group occurred with 1.36 and 1.30 per cent in males and 1.27 and 1.32 per cent in females respectively. Moreover, the blood pressure parameters also decreased significantly (p<0.05) in both the cities. A significant decrease (p<0.01, p<0.05) in total cholesterol (3.02 and 2.92%), Triglycerides level (4.18 and 5.46%), LDL-C (3.73 and 2.82%), VLDL-C (2.21 and 2.81%) while the increase in HDL-C (2.74 and 2.01%) was observed in the subjects of the experimental group in Ludhiana and Jaipur City respectively. The developed bars were highly acceptable, rich in antioxidants, have longer shelf life and can be used in the hospitals to improve the lipid profile of hyperlipidemic subjects.en_US
