Prickly pear (Opuntia ficus indica (L.) Mill.) is a rich source of vitamins C, B1, B2, A, and E, minerals such as calcium, potassium, magnesium, iron, and phosphorus, as well as bioactive substances, i.e., carotenoids, betalains, and phenolic compounds. Of these, the phenolic acids, betalains, and flavonoids are notable in that they are largely responsible for the health-promoting properties of this plant. The purpose of the presented research was to first determine the antioxidant properties and the content of polyphenolic compounds (including individual phenolic acids) in prickly pear fruit, then to produce an innovative gluten-free pasta from rice-field bean flour enriched with various amounts of pear prickly fruit. The content of free phenolic acids, the sum of polyphenols and antioxidant properties of pasta were subsequently determined in the supplemented pasta. Chromatographic analysis (HPLC-ESI-MS/MS) showed a wide variety of phenolic acids. In the fruit sample, 14 acids were detected, whereas in the pasta sample without additives, 9. The dominant acid was isoferulic. The total content of free phenolic acids and the sum of polyphenols increased with increasing content of the functional additive. Moreover, the content of individual acids generally increased as the Opuntia fruit was added. The antioxidant activity was also positively correlated with the addition of fruit, with the content of free phenolic acids and the sum of polyphenols. Our research has shown that our innovative pasta with the addition of prickly fruit can become a source of the free phenolic acids indispensable for human health.

AbstractThere is a growing public interest in fruits labeled as „superfood” (functional food). A “superfood” should have a high content of bioactive substances with a positive impact on human health. Seven different cultivars of goji berry fruits (Lycium chinense Mill.) grown in north-western Poland were evaluated for its physicochemical parameters, antidiabetic and antioxidant activity, and polyphenol content. The length of 1-year-old shoots ranged from 36 cm (‘Big Lifeberry’) to 82 cm (‘Korean Big’). Cultivars from the group of Big were characterized by the biggest fruits (17.3-24.2 mm) with the greatest weight of 100 fruits (96.7­122.1 g). ‘Big Lifeberry’ contained high amounts of L-ascorbic acid (408 mg 1000/g) and provitamin A (190 mg 1000/g) and showed high antidiabetic (α-amylase IC50=33.4 mg/mL; α-glucosidase IC50=9.9 mg/mL) and antioxidant activity (ABTS·+ 6.21 and FRAP 5.58 mmol T/100 g). ‘Big Lifeberry’ was also characterized by a high total content of polyphenols (43.64 mg 100/g). Furthermore, the nitrite content in all the cultivars tested was at a relatively low level. Among the examined cultivars, the most attractive one concerning the consumers’ point of view of the size, weight and high content of health-promoting compounds is ‘Big Lifeberry’.

Buckwheat is a generous source of phenolic compounds, vitamins and essential amino acids. This paper discusses the procedure of obtaining innovative gluten-free, precooked pastas from roasted buckwheat grains flour, a fertile source of natural antioxidants, among them, phenolic acids. The authors also determined the effect of the extruder screw speed and the level of moisture content in the raw material on the quantity of free phenolic acids. The qualitative and quantitative analysis of phenolic acids in pasta was carried out using high-performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS). The chromatographic method was validated. For extracts with the highest total content of free phenolic acids and unprocessed flour from roasted buckwheat grain, the TLC-DPPH test was also performed to determine the antioxidant properties of the tested pasta. The level of moisture in the raw material had an impact on the content of phenolic acids. All pastas made from buckwheat flour moistened up to 32% exhibited a higher total content of free phenolic acids than other mixes moistened to 30 and 34% of water.

Chestnut fruit abounds in carbohydrates, proteins, unsaturated fatty acids, fiber, polyphenolic compounds, as well as vitamins and micronutrients, that are behind the health-promoting properties of this plant. The purpose of the discussed research was to obtain innovative gluten-free pasta from rice and field bean flour enriched with a various addition of chestnut flour. Regarding the studied pasta, the following were determined: the content of free phenolic acids, total polyphenols, and antioxidant properties. Chromatographic analysis (HPLC-ESI-MS/MS (high-performance liquid chromatography-electrospray ionization tandem mass spectrometry)) revealed a wide variety of phenolic acids. In a sample with 20% and higher content of chestnut flour, as many as 13 acids were detected. Isoferulic acid prevailed. The total content of free phenolic acids and total polyphenols increased along with the increasing chestnut content. Moreover, in most cases, the content of individual acids increased with the addition of chestnut flour. Besides, the antioxidant activity was positively correlated with the addition of chestnut fruit flour, the content of free phenolic acids, and total polyphenols. Our research has demonstrated that our innovative gluten-free pasta, with the addition of chestnut flour, has a potential to be a source of polyphenolic compounds, including free phenolic acids, that are valuable for human health.

Goji fruit (Lycium barbarum L.) has been identified as a polyphenolic compound plant source of noted richness. It also contains polysaccharides, carotenoids, vitamins and minerals, fatty and organic acids. The purpose of the presented research was to produce innovative instant corn gruels with various dry goji berry contents (1, 3 and 5%), to determine the level of included polyphenolic compounds (including individual free phenolic acids) and to assess the antioxidant properties of these functional-food products. A further objective was to identify the optimum value of one of the most important production parameter, the rotational speed of the extruder’s screw during gruel processing. The undertaken chromatographic analysis (LC-ESI-MS/MS) showed a wide variety of available phenolic acids. In the samples with 5% addition of fruit, eight phenolic acids were detected, whereas in the corn gruel without additives, only five were noted. The antioxidant activity, the content of free phenolic acids and the sum of polyphenols increased with increase of the functional additive. For all goji content, screw speeds of 100 and 120 rpm rather than 80 rpm resulted in higher polyphenol amounts and greater Trolox equivalent antioxidant capacity, as well as higher ability to scavenge DPPH.

The content of two groups of compounds with biological activity (non-hallucinogenic indole compounds and free phenolic acids) were analyzed in extracts of fruiting bodies of four species of Phellinus: P. igniarius, P. pini, P. pomaceus and P. robustus. The presence of indole compounds in methanolic extracts was analyzed by high-performance liquid chromatography and thin-layer chromatography coupled with densitometric detection. Three metabolites (serotonin, tryptamine, and L-tryptophan) were identified. The contents of individual indole compounds ranged from 1.70 (tryptamine in P. robustus) to 8.32 mg x 100 g1 dry weight (L-tryptophan in P. robustus). Four free phenolic acids were detected in methanolic extracts by the HPLC method. The total content ranged from 9.9 mg x 100 g1 DW (P. igniarius) to 32.5 mg x 100 g1 DW (P. robustus).

The biological activity of chocolates gains more and more attention of consumers. Its antioxidant properties depend, among other factors, mainly on the origin of cocoa and the characteristics that this origin gives to the final product. Therefore, the aim of the study was to measure and compare the total content of polyphenols, antioxidant activity, and key odorants of commercial chocolates made from blend cocoa with single-origin ones. The highest content of polyphenols was found in 90% blend cocoa chocolate and single-origin samples, while the lowest content was exhibited by 100% chocolate from blend cocoa mass. The highest antioxidant activity measured by 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) and ferric reducing antioxidant power (FRAP) assays was observed in the sample of chocolate with 90% cocoa solids from blend mass, followed by single-origin chocolates. A high positive correlation between ABTS assay and the total polyphenol and phenolic acids’ content, as well as among the total content of polyphenols, flavonoids, and phenolic acids was found. Mineral composition analysis showed that dark chocolate is a valuable source of some elements, especially Mg, Fe, and Zn. Potentially toxic elements were not detected or below permitted limits. Moreover, it was noticed that the main volatile compound in all tested samples was acetic acid, but pyrazines were considered the most important group of chocolate odorants.

AbstractChokeberry fruit (Aronia melanocarpa (Michx.) Elliott) is known for its antioxidant properties and generally beneficial impact on human health. The aim of the research was to produce innovative corn porridge with a different content of chokeberry fruit percentage-wise and to test it to determine the content of polyphenolic compounds, including flavonoids and individual free phenolic acids, and determine the antioxidant properties of analysed extracts. One of the objectives was also to identify the optimum porridge production parameters, including, among other things, the rotational speed of the extruder screw during the extrusion process.Obtained results showed that an increased content of chokeberry fruit in porridge enhances its antioxidant properties, as well the content of polyphenols, flavonoids, and free phenolic acids. The greatest free radicals scavenging activity by all extracts was reported after 10 minutes of the process. The results of the above study demonstrate that extruded porridge enriched with chokeberry fruit have a potential for becoming a good source of natural antioxidants, and the extrusion process at 80 rpm does not degrade the tested active compounds.

Abstract The chemical analysis of dried pomace of chokeberry, apple, black currant, strawberries and carrot was performed to determine the composition and content of nutrients and bioactive substances, among others the content of vitamins, phenolic acids, anthocyanins, and essential fatty acids. The antioxidant properties were determined in the extracts of pomace by determining the total antioxidant potential (TRAP) and antioxidant activity against DPPH radical. Tested pomaces contained 12-15% protein, approximately 18-20% crude fibre, approximately 2.7-4.0% ether extract and 1.8-3.0% ash. The highest level of anthocyanins was found in chokeberry pomace, followed by black currant pomace and several times less in strawberries and apples. The content of phenolic acids ranged from 12.91 mg/100 g in black currants to 630.30 mg/100 g in dried chokeberries. In terms of vitamins the richest source of vitamin E was chokeberry pomace (152.3 mg/100 g), while most of the carotenoids were found in dried carrot (15.35 mg/100 g). The chain of antioxidant activity was as follows: black currant>chokeberry>apple>strawberry>carrot, while in terms of antioxidative capacity it was chokeberry>apple>black currant>strawberry>carrot.

A new type of multigrain snack has been designed containing varied additions of Moldavian dragonhead (Dracocephalum moldavica L.) seeds. The antioxidant properties and the general health benefits of this plant material have already been widely acknowledged. The research discussed herein aimed to investigate the influence of the formulation and expansion method (frying) on the content of polyphenolic compounds, individual phenolic acids, and antiradical properties of innovative snacks enriched with dragonhead seeds. The highest content of polyphenols (0.685 mg GAE/mL), free phenolic acids (47.052 µg/g of dry matter), and highest radical scavenging activity (96.23% towards DPPH) were found in the fried snacks enriched with 22% of seeds. In these samples, 11 phenolic acids were detected. Strong positive correlations were seen between the addition of dragonhead and the polyphenol content (r = 0.989) and between the quantity of the enriching additive and the content of free phenolic acids (r = 0.953). The research has shown that such innovative snacks have the potential to supply health-benefiting free phenolic acids, e.g., salicylic, isoferulic, ferulic, p-coumaric, vanillic. Our studies provide an introduction to the development of a new range of functional foods.

The main purpose was to demonstrate differences in the total content of phenolic compounds, phenolic acids and to analysis differences in the antioxidant properties of extracts obtained from seeds of several narrow-leaf lupine cultivars ( Lupinus angustifolius L.). The biological material consisted of seeds of four cultivars of narrow-leaf lupine characterized by different concentrations of alkaloids. The total content of phenolics was determined with the colorimetric method using the Folin-Ciocalteau reagent. Other determinations included the ability of seed extracts to scavenge DPPH• radicals and ABTS•+ cation radicals. The reducing power of the extracts was also determined. Chromatographic and qualitative separation of the phenolic compounds present in seeds was performed with the RP-HPLC method. Out of the four cultivars, the bitter narrow-leaf lupine produced seeds with the highest total content of phenolic compounds, which was also correlated with its antiradical characteristics. In the analyzed seeds were also found to contain three phenolic acids: ferulic, sinapinic and p-coumaric one.
