Development of Nutrient-rich Cake with Supplementation of Pea Shells Powder and Nutritional Evaluation

Abstract

Background: Bakery products like cakes are rich in starch, fat, and energy but deficient in fiber, vitamins, and minerals. The cake is becoming a well-known delicacy during festival periods between all age groups mostly in urban areas. Providing a healthy and nutritious cake remains a main problem on account of extreme sugar or fat content that predisposes the buyers to obesity. Mixing the flours with plant components helps solve problems of low nutritive value of cereals. Pea shells are an excellent source of nutrients and have excellent functional properties, the substitution of flour with pea shells powder is the best way for consuming the nutrients which are likely to contribute substantially to the fight against targeted hunger and to bridge the gap of malnutrition. Keeping the view of the potential of pea shells powder in formulated products the healthy and nutritious cakes were investigated. Methods: Three cakes were developed with different formulations that include refined flour and pea shells powder in the ratio of 100:0, 90:10, and 80:20 with other basic ingredients of baking. The developed cakes were analyzed for organoleptic and nutritional properties such as proximate, dietary fiber, and minerals. Result: The sensory mean score was increased by the supplementation of pea shells powder. The result showed that 10% level was the optimum level of incorporation. A significant increase (0 greater than 0.05) in the nutrient contents such as protein (10.97 to 12.38%), crude fiber 90.31 to 1.85%), ash, calcium (53.33 to 193.33 mg/100 gm), potassium (162.48 to 335.42 mg/100 gm), magnesium (56.75 to 253.33 mg/100 gm), iron (3.94 to 5.49 mg/100 gm), and potassium (162.48 to 335.42 mg/100 gm) of incorporated cakes and decreased the fat (25.55 to 21.72%), energy (451.83 to 413.76 kcal/100 gm) content compared to control cake. The calcium and magnesium content increased two or four times more than control cakes. From the present study, it can be concluded that cakes containing 20% pea shells powder were nutritionally rich.
