“…In a preliminary study, anthocyanins of elderberry fruits used as a raw material for producing the concentrate have been previously identified and reported (Szalóki‐Dorkó et al ., ) that were cyanidin˗3˗ O ˗glucoside (CyG, m/z 449.1095), cyanidin‐3‐ O ‐sambubioside (Cy2G, m/z 581.1516) and cyanidin‐3‐ O ‐sambubioside‐5‐ O ‐glucoside (Cy3G, m/z 743.2041). These results are in accordance with literature data (Hong & Wrolstad, ; Wu et al ., ; Kaack et al ., ; Veberic et al ., ).…”

Elderberry concentrate is widely used for food colouring. Its production includes several processing steps, which influence pigment composition, thus affecting the quality of final product. In this study, qualitative and quantitative changes in anthocyanin components were followed during the production of elderberry juice concentrate using Haschberg and Samocco varieties. Juice concentration resulted in more than fivefold concentration increase in anthocyanins; however, clarification, filtration and evaporation steps caused slight but continuous decrease in anthocyanins relative to the dry matter of the product. Pectolytic enzymatic treatment was found to be one of the most critical processing steps that affects anthocyanin yield during production, and this effect on yield can be variety-dependent. Additionally, two condensed dimeric anthocyanin species generated after heat treatment are reported for the first time to be present in elderberry juice concentrate. Our results suggest that cyanidin-based anthocyanin conjugates with more complex saccharide moieties are more robust during production.

The aim of this study was to evaluate the effect of microfiltration (MF) on the antioxidant capacity of elderberry juice using ceramic membrane. Previous to MF measurements preliminary examination was achieved with different enzymes. Four different samples were prepared: one without any enzyme and three with different pectolytic enzymes. The resistances were determined using the resistance-in-series model and difference between four enzyme-treated samples are evaluated. The effect of this technology on the antioxidant component of the clarified elderberry juice has been evaluated in permeate and retentate samples. For ferric reducing antioxidant power was measured with FRAP and total phenolic content (TPC) was determined with Folin Ciocalteau reagent. The total anthocyanin content (TAC) was estimated using spectrophotometric method. Higher juice yield was obtained using enzyme compared with enzyme-free elderberry pulp. The analytical results show that the MF membrane retained the valuable components in different rate. Significant losses are believed to have occurred after the MF clarification process due to fouling layer resistance, what can be decreased with pectolytic enzymes treatment.

“…Some of them have antioxidant (Manimala et al, 2014;Cassia et al, 2005), antimicrobial (Vendruscolo et al, 2014) and anticarcinogenic properties (Deshmukh et al, 2009). These biopigments can be obtained from various natural sources such as higher plants like elderberries (Sambucus nigra) (Szaloki-Dorko et al, 2015), black grape skin, red beetroots (Beta vulgaris), oil palm fruits, seeds from annatto (Bixa orellana), paprika (Capsicum annum L.) and tomato (Lycopersicon esculentum). Pigments can also be obtained from animals such as insects like kermes (Kermes vermilio) and cochineal (Dactylopius coccus) (Yilmaz et al, 2014).…”

Pigments from various sources such as annatto seeds, cochineal, beet root, and microalgae are widely used in food, pharmaceutical, cosmetics, textile and other industries. However, these sources of pigments have various limitations such as toxicity and environmental pollution of synthetic pigments, and low productivity of pigments from higher organisms due to long period of growth. The objective of this study was to screen for pigment producing fungi to overcome some of the above limitations. A pigment producing fungus was isolated from soil sample collected from cassava processing site and was identified as Talaromyces purpurogenus based on the colony morphology and characteristics, microscopic observation of the conidia and conidiophores and analysis of the gene sequence of internal transcribed spacer (ITS) region of the rDNA. The nucleotide sequence was deposited in Genbank (DDBJ/ EMBL) and was assigned the accession number LC128689. Pigment production by the isolate in solid state cultures using PDA as substrate in Petri dishes was investigated. The optima culture conditions were pour plating method with agar overlay (4 mm thick) and sealed edges, inoculum spore concentration of 2×10 8 spores/Petri dish and incubation in dark at 30°C. Under these culture conditions, the red, orange and yellow pigments produced were 11.2, 7.3 and 8.21 unit optical densities per gram of wet agar respectively after 96 h of cultivation. The isolate has good potential for production of different shades of pigments for various applications.
