Physical and chemical parameters and vitamin composition of powders from dried fruit and berry squeezings out

Abstract

The article presents the investigation results of physical and chemical indexes (mass fraction of dry substances, mass fraction of pectines, mass fraction of moisture, mass fraction of crude fiber, mass fraction of total sugar in invert form, mass fraction of titrable acid concentration), powders vitamin composition (β-carotene, E, C, B1, B2, PP) prepared from squeezings of fruit and berry dry crops such as Japanese quince (Chaenomeles јaponica (Thumb.), European elder (Sambucus nigra L.), gooseberry (Grossularia reclinata (L.) mill), raspberry (Rubus idaeus L.), sea buckthorn (Hippophae rhаmnoidеs L.), plum tree (Prunus L.), red currant (Ribes rubrum L.), black currant (Ribes nigrum L.), mountain ash (Sorbus aucuparia L.), black chokeberry (Aronia melanocarpa (minch) Elliott.) and apple tree (Malus domestica Borkh.). As a result of the investigation the largest content of pectines was found at the sea buckthorn ‘Otradnaya’ (20.7%), crude fiber from raspberry of the variety ‘Barnaulskaya’ (38.6%), sugars from apple tree variety ‘Antei’ (48.9%), titrable acid from black currant variety ‘Katusha’ (8.4%), β-carotene from sea buckthorn variety ‘Otradnaya’ (32.77 mg/100 g), vitamin E from sea buclthorn ‘Botanicheskaya’ (44.5 mg/100 g), vitamin C from black currant variety ‘Katusha’ (83.1 mg/100 g), vitamin B1 from gooseberry variety ‘Masheka’ (0.83 mg/100g), vitamin B2 from gooseberry variety ‘Ravolt’ (3.77 mg/100g) and vitamin PP from raspberry squeezings of the variety ‘Barnaulskaya’ (5.68 mg/100g). Powders prepared from squeezing of various dry fruit and berry crops gotten in the production process of fruit and berry canned goods may serve as an additional vitamins and organic substances entering in a man’s body necessary for its normal activity.
