Plants are essential sources of bioactive substances that promote health. For economic reasons, farmers usually focus on obtaining higher yields rather than crop nutraceutical quality. The application of non-essential elements (NEEs) is a technique used to increase secondary metabolites (SMs) in plants. This technique includes variations of the essential elements ratios in a nutrient solution or the inclusion of elicitors, such as salicylic acid or methyl jasmonate. Elicitor use is controversial because plants grow differently in inert substrates, in vitro and soil. Soil contains essential elements (EEs) and NEEs that can enhance SM synthesis and increase nutraceutical plant quality. However, any technique that modifies plant metabolism can decrease yields. Thus, developing techniques to increase both agricultural product yield and quality is necessary. This review aims to demonstrate the necessity for a new recipe or "cocktail" of plant nutrients based on EEs and NEEs, and elicitors apply to achieve both a high yield and crops nutraceutical quality.

“…Beneath varieties and substrates used, climatic and growth conditions seem to be of great influence which will be pointed out in the subsequent review. Concentration levels encountered within this work (Table 1) were similar to those reported from hydroponic cultures in Germany and Denmark [11], whereas concentration levels found in tomatoes from the Mediterranean (Spain [12], Turkey [13]) or South America [14] were much higher, particulary for Cd, Al and Fe. From Thailand, however, even lower levels have been reported [15].…”

“…Bressy et al [14] compared element contents of tomatoes of variety "Italy", organically and conventionally grown, and randomly collected from municipal markets in Salvador, Bahia, Brazil. In conventionally cultivated tomato samples (varieties Khaki, Cherry, and "Italy"), most element concentrations in dry weight steadily increased from early to final maturation, except Ba, Mn, Cd, Hg, and Se.…”

Main and Trace Element Contents of Tomatoes Grown in Austria

Tomatoes are one of the most popular and widespread kinds of vegetables on a global scale. Tomatoes of various varieties, sizes and shapes, were grown in 3 different greenhouses in Austria on solid substrates. After freeze drying, they were analyzed for main and trace elements by ICP-OES, ICP-MS, and combustion methods (for C, N). Main inorganic cation was K, whereas contents of hazardous metals (e.g. Cd, Pb), Rare Earth Elements, Si, and Ti were marginal. Due to high water contents, the contribution to the Recommended Daily Intake of essential elements is largely below 1/5 for 1 kg consumption. In spite of different varieties grown at the 3 sites, trends for concentrations versus fruit size could be noted for K, Ca, S, B, Cu, Fe, Zn and Si. Similarly, fruits with seeds + jelly tended to contain more of almost all elements, but less of Li, Ca, Sr, and Ba, whereas P and B were equally distributed. No significant correlations between the concentrations found in tomato-fruits and the amount of soil mobilizable in 0.16 M acetic acid (exchangeable + acid mobile) were found. A look into already published data from other countries reveals that element concentrations met in tomatoes presumably depend on climatic conditions and suitably adapted varieties than on the growing substrate.

“…Therefore, ICP-MS is considered to be one of the most effective tools for determining the provenance of tea (Chudzinska et al, 2012;Herwig et al, 2011). This technique has been employed for the determination of trace metals in olive oil (Llorent-Martínez et al, 2011), honey (Chudzinska and Baralkiewicz 2011), tomato (Bressy et al, 2013), and particularly in tea. The number of studies on the application of this technique to tea has increased in recent years (Chudzinska and Baralkiewicz 2011;Llorent-Martínez et al, 2012;Pilgrim et al, 2010), but these studies only dealt with identifying the geographical origin of tea samples, and not with associating location with the types of tea.…”

In this study, 35 black, oolong, and green tea samples from China were analyzed by inductively coupled plasma mass spectrometry after a digestion method was developed on the basis of a response surface methodology. Linear discriminant analysis of whole data sets was performed in order to discriminate and classify Chinese tea samples according to their origin and type. The analysis revealed an excellent separation between tea samples according to their type and origin with a discrimination efficiency of 100%. The varieties of selected elements in Chinese tea were analyzed based on their origins and types. Keywords: tea, ICP-MS, minerals and trace elements, authenticity IntroductionTea (Camellia sinensis L) is a highly popular nonalcoholic beverage consumed by over two-thirds of the world's population owing to its medicinal and refreshing effects (Karak and Bhagat 2010). Since tea contains several essential nutrients and trace elements, drinking tea is considered beneficial for human health.The presence of heavy metals at trace levels in tea has received much attention because they are directly related to health.The efficacy of discriminating the geographical origin of teas is complicated by disparities in growing conditions such as soil and climate . The attributes of tea according to its geographical origin are also often recognized and appreciated by the consumers. Therefore, the discrimination of tea according to its geographical origin is presently the focus of attention (MoredaPiñeiro et al., 2003). However, it is not easy to determine its geographical origin by sensory evaluation. On the other hand, since elemental composition can provide accurate information about the provenance (Cubadda et al., 2006) of a tea sample, it is possible to identify the origin of tea on the basis of its elemental composition.In general, based on the different processing methods, teas are classified as: unfermented green tea (GT), fully fermented black tea (BT), and partially fermented oolong tea (OT), which are the most popular and frequently consumed teas in the world (Han et al., 2014). The processing method used affects the concentrations of elements in the processed tea. Therefore, the discrimination of tea types based on elemental fingerprinting is very urgent and important.Because of its low limit of detection (LOD) and multi-element measurement capability (Salomon et al., 2002), inductively coupled plasma mass spectrometry (ICP-MS) is used in a number of food analysis laboratories for determining elements at trace and ultratrace levels (Walczyk 2001). Therefore, ICP-MS is considered to be one of the most effective tools for determining the provenance of tea (Chudzinska et al., 2012;Herwig et al., 2011). This technique has been employed for the determination of trace metals in olive oil (Llorent-Martínez et al., 2011), honey (Chudzinska and Baralkiewicz 2011), tomato (Bressy et al., 2013, and particularly in tea. The number of studies on the application of this technique to tea has increased in recent years (Chudzinska ...
