AB  - Cocoa beans are part of the cocoa plant fruit (Theobroma cacao L.) used to prepare various
products such as chocolate, cocoa butter, jelly, liqueurs, cosmetics, etc. Dark chocolate is consumed
worldwide by different populations and is known for its good taste, making it one of the most
favoured food products. This work aimed to determine the content of total polyphenols (TPC), total
flavonoids (TFC), and the antioxidant potential measured through the ability to scavenge DPPH
free radicals (DPPH), ferric reducing power (FRAP), and total antioxidant capacity (TAC), as well as
major and trace elements contained in twelve commercially available dark chocolate samples, with
cocoa content ranging from 40% to 99%. The total polyphenols content ranged between 10.55 and
39.82 mg/g GAE, while the total flavonoid content was from 10.04 to 37.85 mg/g CE. All applied
antioxidant assays indicate that the sample with the highest cocoa percentage shows the greatest
antioxidant activity (DPPH: 48.34% of inhibition; FRAP: 89.00 mg/g GAE; TAC: 83.86 mg/g AAE).
Statistical methods were applied to establish the differences between the samples concerning TPC,
TFC, DPPH, FRAP and TAC, as well as to differentiate the samples according to the mineral content.
The results indicated that the differences in TPC and TFC between different samples depended on
the cocoa content and the addition of dried fruit pieces. A good correlation between antioxidant
potency composite index (ACI) and declared cocoa content was noticed (R
2 = 0.8034), indicating
that the declared percentage of cocoa is a reliable indicator for antioxidant activity of analysed dark
chocolate samples. The nutritional evaluation proved that the studied chocolate samples were an
excellent source of Mg, Fe, Mn and Cu.

AB  - The goal of this study is to evaluate the quality
of seven natural mineral water sources in the Vrnjačka
Banja area used in the treatment of various diseases. The
24 macro- and microelements were determined by induc tively coupled plasma optical emission spectrometry (ICP OES). The results show that element content was within
allowed limits of concentration, except for B, As, and Se.
The evaluated content of these elements can be associated
with geological and anthropogenic factors. The sample S6
contains more than twice the concentration of As, meaning
that the use of water from this source should be limited due
to the negative impact of this element on human health.
The calculated values of weekly (EWI) and oral (OI)
intakes as well as the acute hazard quotient (HQA) of
selected toxic and potentially toxic elements indicate no
health risks to the consumers. The highest hazard quotient
(HQL) observed for As in sample S6 (2.0·10−1
)
demonstrated a significant risk of carcinogenic diseases
in long-term consumption from this source. The estimated
non-carcinogenic (DIA) and carcinogenic (DIL) dermal
intakes with acute (HQA) and long-term (HQL) hazard
quotient values for sample S3 show that there is no health
risk to those who use the water from this thermal source for
bathing. The presence of aerobic mesophilic bacteria at 22
°C and 37 °C in samples S3, S6, and S7 as well as sulphite reducing Clostridia species in sample S5 were detected,
potentially indicating some non-faecal or faecal
contamination.
