“…As these belong to the macro elements, high amounts are to be expected. Several studies reported potassium, magnesium, and calcium as the highest concentrated elements in roasted coffee beans [56][57][58][59]. Ballesteros et al reported potassium as the most abundant element in a mixture of arabica and canephora CS, followed by magnesium [12].…”

Coffee silver skin is produced in large amounts as a by-product during the coffee roasting process. In this study, coffee silver skin of the species Coffea arabica L. and Coffea canephora Pierre ex A. Froehner as well as silver skin pellets produced in the coffee industry were characterized with respect to both nutritional value and potential heat-induced contaminants. Enzymatic-gravimetric/chromatographic determination of the dietary fiber content showed values ranging from 59 to 67 g/100 g with a comparably high portion of soluble fiber, whereas low molecular weight soluble fiber was not detected. Compositional and methylation analysis indicated the presence of cellulose and xylans in the insoluble dietary fiber fraction, whereas pectic polysaccharides dominate the soluble dietary fiber fraction. The protein content as determined by the Kjeldahl method was in the range of 18 to 22 g/100 g, and all essential amino acids were present in coffee silver skin; whereas fat contents were low, high ash contents were determined. Elemental analysis by inductively coupled plasma mass spectrometry (ICP-MS) showed the presence of macroelements in large amounts, whereas toxic mineral elements were only detected in trace amounts or being absent. Acrylamide was quantified with levels of 24–161 µg/kg. Although 5-hydroxymethylfurfural was detected, its concentration was below the limit of determination. Furfuryl alcohol was not detected.

Coffee is the most worldwide accepted beverage, which has become the second most valuable commodity after oil (Bae et al., 2014). It is the paramount commercialized product with over 3 billion cups of coffee drinks consumed worldwide every day (International Coffee Organization, 2020; Al-Dalain et al., 2020). Coffee is a complex mixture of thousands of chemical compounds responsible of its flavor and aroma, carbohydrates, lipids, nitrogenous compounds, vitamins, minerals, alkaloids, and phenolic compounds (Gonzalez & Ramirez-Mares, 2014). Coffee is rich in many bioactive substances (trigonelline, chlorogenic acid, diterpenes, caffeine), and its consumption has been associated with many beneficial effects (Chu et al., 2009). These include, but not limited to, reduced risk of hepatocellular carcinoma (Johnson et al., 2011), anti-proliferative effect against some human cancer cell lines (Tai et al., 2010), and therapeutic potential against Alzheimer's disease (Arendash & Cao, 2010), and coffee consumption prevents diabetes and fights liver disease (Cano-Marquina et al., 2013). Specialty coffee is coffee which is standardized by the whole coffee process cycle from choosing coffee plantation criteria's till coffee brew serving to client. Specialty coffee flavor is focused on

Tea is a highly common beverage worldwide. In addition to other particles, it contains a range of minerals and trace elements. Even though many are necessary for humans, some could be hazardous. Scientists have long been interested in the toxicity of trace metals and how they affect human health. By using Flame Atomic Absorption Spectrophotometer, the amounts of Ni, Cu, Cd, Zn, Pb, Cr, and Mn in eight black tea leaves, five green tea leaves, and their infusions were examined. The tea samples were collected from Bangladeshi local markets. The infusion time in boiling water was 5 and 10 minutes. Results revealed that the concentration ranges of Ni, Cu, Cd, Zn, Pb, Cr and Mn in black and green tea leaves and their infusions of 5 minutes and 10 minutes were 1.82 to 41.32, 13.54 to 29.87, 0.48 to 2.16, 0.30 to 36.52, 0.04 to 3.89, 0.00 to 4.95 and 112.67 to 187.98 ppm respectively. Concentrations of the elements found in samples were compared with maximum values reported by World Health Organization (WHO). To verify the accuracy of the work, standard reference material (SRM) and certified reference material (CRM) were also tested alongside tea samples. Geographical fluctuations, seasonal changes, chemical characteristics of the soil of the cultivated area, plant age, manufacturing, and packaging process are responsible for the variances in metal content of several tea brands. Cd, Pb, Cr, and Ni’s target hazard quotients (THQ) and the hazard index (HI) from drinking tea were both below one, indicating no risk to human health.
