Development оf the Recipe Composition of a Functional Snack Bar Based on Vegetable Ingredients

Abstract

Advances in the development of modern snack bar formulations demonstrate the wide variety of ingredients used and their combinations. At the same time, the prevailing trends in the food market orient manufacturers towards the active use of ingredients of plant origin. Analysis of literary sources made it possible to substantiate the choice of recipe ingredients for creating a functional snack bar: processed products of raspberries and blueberries, apples, dates, cashews, soy protein isolate. The use of a new combination of known ingredients requires solving a number of problems that make a key contribution to the creation of product technology and the development of its formulation. The aim of the study was to experimentally substantiate and develop a recipe for a ready-to-eat functional snack bar based on herbal ingredients. The work used raw materials that meet the requirements of GOST, TU, and generally accepted methods of analysis: determination of polyphenolic compounds, flavones, flavonols was carried out by spectrophotometric method; organic acids and vitamin C - by titrimetric method; nutritional value of snack bar samples by protein, fat, carbohydrates and dietary fiber content - by calculation method. As a result of the research carried out, the recipe for the snack bar was experimentally substantiated and developed, taking into account the new composition of the selected herbal ingredients; technological solutions for its implementation are proposed. It has been shown that berry ingredients used in work (concentrated raspberry and blueberry juices, freeze-dried blueberry powder and freeze-dried raspberries) are a source of natural components useful for human health - organic acids, polyphenolic compounds, including flavones and flavonols, as well as vitamin C. The combination of berry ingredients with other recipe components - date paste, apple syrup, apple fibers, soy protein isolate, cashew nuts - results in a finished product with acceptable taste and consumer properties and an increased content of protein and functional food ingredients - vitamin C and dietary fiber. It was found that the consumption of one serving (50 g) of a snack bar obtained according to the proposed recipe allows satisfying the physiological need of an adult in protein by 5.7-10.8%, fats - 1.1-2.5%, digestible carbohydrates - 5.4 -12.6%, dietary fiber - 14.4 -18.0%, vitamin C - 11.2%, covering an adequate level of consumption of flavones and flavonols - by 45.5%. The snack bar obtained according to the developed recipe contains only natural sugars and can be positioned as a product that is a source of protein, vitamin C and a product with a high dietary fiber content. The results of the research carried out can be recommended for use in production to expand the assortment line of healthy snacks. For the development of a complete package of technological solutions, directions for further research are outlined, which will be aimed at finding and justifying effective packaging solutions that ensure the quality, safety of the product and the safety of biologically active substances during storage
