Enriched plum filling for the confectionery

Abstract

The useful nutritional value of plum is related to the most quantity of vitamins like Vitamin A - beta carotene, Thiamin (B1), Riboflavin (B2), Niacin (B3), Pantothenic acid (B5), Vitamin B6, Folate (B9), Vitamin C, Vitamin E, Vitamin K; and minerals: Ca, Fe, Mg, Mn, Ph, K, Na and other. Plum is available in the receipts of various confectioneries: sweets, caramels, creams, jellies, cookies and others. The objective of the presented study was to develop a new of natural origin with antioxidants capacity - plum filling for the confectionery. Sensory assessment of the researched samples was provided by “Just-About-Right-Test” questionnaire for the following main characteristics: taste, colour, odour, texture or consistence and acceptance of the product. Organoleptic and physicochemical characteristics were analyzed in accordance with the GOST 32741-2014 (Interstate standard) requirements. The content of mineral substances was determined by the method of Mass-spectrometry with inductively coupled plasma (ICP-MS) and using a Scanning Electron Microscope (SEM). As a result of the «Just-About-Right-Test» most of the respondents selected a plum filling sample with gelatin and lemon. This statement was confirmed by organoleptic and physicochemical characteristics. The mass-spectrometry database verified availability of essential macro- and microelements: sodium, magnesium, phosphorus, sulphur, potassium, calcium, iron and other. The proposed plum filling has wide range applications, as inside and outside for the covering of confectionery, thereby organoleptic properties and nutritional value of final product could be enriched.
