The study aimed to investigate the impact of adding plant-based protein preparations to cookie recipes on their quality and nutritional value. The results showed that the addition of plant protein preparations improved the nutritional value of cookies by supplementing with essential amino acids. Pea and sunflower proteins were found to enhance the appearance of the cookies, while cookies with the best sensory values were obtained using pea protein preparation.
BACKGROUND The objective of the study was to determine the effect of addition of plant-based protein preparations in cookie recipes on the quality and nutritional value of the obtained products. Wheat flour was replaced by 10%, 20% or 30% of pea, hemp seed, pumpkin and sunflower seed preparations. Baked cookies were analysed for chemical composition, amino acid profile, colour and texture as well as organoleptic attributes and overall acceptability. RESULTS The addition of plant protein preparations improved the nutritional value of cookies by supplementing them with threonine and part of lysine. Replacing at least 20% of wheat flour with pea protein allowed the production of cookies with a well-balanced amino acid profile. The use of pea and sunflower proteins improved the appearance of the obtained products (consumer notes from 7.4 to 8.0) in comparison to the control sample (note 7.2). The physical properties of cookies were changed while organoleptic properties worsened. Cookies with the most desirable sensory values were obtained using the pea protein preparation. Acceptable cookies were also obtained with pumpkin and sunflower seed protein preparations, if the proportion of additive did not exceed 20% in relation to the amount of wheat flour. CONCLUSION The use of protein preparations from pumpkin and sunflower as well as from hemp seeds allows the production of cookies with acceptable sensory characteristics that could diversify the range of cookie products. In the case of oilseed preparations, the amount of additive is limited primarily by the colour and taste of the finished products. (c) 2022 Society of Chemical Industry.
