Pinni is a popular traditional milk-cereal based sweet of northern states of India viz., Punjab, Haryana and Delhi. Market samples were collected and were evaluated for various quality attributes. Quantitative Descriptive Analysis revealed significant difference (p<0.05) in sensorial, physico-chemical, textural attributes of pinni among the market samples. Principal Component Analysis identified key six components comprising of shape, crumbliness, cooked flavour, colour, firmness, oxidized flavour, gumminess, chewiness, cohesiveness, surface appearance and coating and moisture absorption, which governed 78.66% of the variation in the sensory scores of pinni. Hence, these attributes may be given prime importance while developing technology for industrial scale production of pinni.
Pinni is an immensely popular traditional milk-cereal based sweet of northern states of India. Ingredients for production of pinni are ghee, wheat flour, sugar, pulses and khoa. In the production of pinni, slight variations in the processing parameters such as level of wheat flour, ghee, powdered sugar and roasting time can affect the quality significantly. Hence, these processing parameters were standardized using response surface methodology (RSM) and their effect on texture, microstructure, physico-chemical and sensory attributes of pinni was studied. The solution having maximum desirability of 0.773, corresponding to 44.99 parts of wheat flour, 35.62 parts of ghee, 24.99 parts sugar and 9.06 min roasting time was selected as optimized condition for pinni preparation. Scanning electron microscopy study effectively described the changes occurred in protein and starch particles of pinni during different stages of production.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
