“…However, higher-value rice with geographical indication status can be affected by fraud, which damages consumer trust and leads to food safety issues. , Therefore, it is increasingly important to promote the supervision of the quality and safety of Chinese rice by government departments and regulatory agencies. In recent years, stable isotopes have been widely applied for the authenticity determination and origin traceability of agricultural products. − Stable isotope characteristics of rice and rice plant tissues are affected by geographical environment factors , such as local water quality and abundance, but the influence of different water isotope compositions on the stable isotopes of rice is not clear.…”

Rice origin authenticity is important for food safety and consumer confidence. The stable isotope composition of rice is believed to be closely related to its water source, which affects its origin characteristics. However, the influence of water availability on the distribution of rice stable isotopes (δ 2 H and δ 18 O) is not clear. In this study, three irrigation waters with different isotopic values were used to investigate isotopic water use effects of Indica and Japonica rice, using pot experiments. Under three different water isotope treatments, the δ 2 H values of Indica polished rice showed significant differences (−65.0 ± 2.3, −60.5 ± 0.8 and −55.8 ± 1.7‰, respectively, p < 0.05) compared to δ 13 C and δ 15 N, as did Japonica polished rice. The values of δ 2 H and δ 18 O of rice became more positive when applying more enriched (in 2 H and 18 O) water, and the enrichment effect was higher in rice than in the corresponding plant tissue. In addition, the δ 2 H and δ 18 O values of Indica rice leaves decreased at the heading stage, increased at the filling stage, and then decreased at the harvest stage. Japonica rice showed a similar trend. δ 2 H changes from stem to leaf were more negative, but δ 18 O changes were more positive, and δ 2 H and δ 18 O values from leaf to rice were more positive for both brown and polished rice. The results from this study will clarify different water isotopic composition effects on rice and provide useful information to improve rice origin authenticity using stable isotope-based methods.

“…The main aim of these studies was related to the authenticity control of honey in terms of its geographical origin, without further correlation with its medicinal properties. Thus, reliable models for origin discrimination have been reported for honey originating from Romania [15], France [15], Greece [29,30], Italy [31,32], China [33,34], and Brazil [35]. However, these studies were not performed with the aim of identifying the compositional differences in a certain type of honey produced in several countries.…”

Nowadays, in people’s perceptions, the return to roots in all aspects of life is an increasing temptation. This tendency has also been observed in the medical field, despite the availability of high-level medical services with many years of research, expertise, and trials. Equilibrium is found in the combination of the two tendencies through the inclusion of the scientific experience with the advantages and benefits provided by nature. It is well accepted that the nutritional and medicinal properties of honey are closely related to the botanical origin of the plants at the base of honey production. Despite this, people perceive honey as a natural and subsequently a simple product from a chemical point of view. In reality, honey is a very complex matrix containing more than 200 compounds having a high degree of compositional variability as function of its origin. Therefore, when discussing the nutritional and medicinal properties of honey, the importance of the geographical origin and its link to the honey’s composition, due to potential emerging contaminants such as Rare Earth Elements (REEs), should also be considered. This work offers a critical view on the use of honey as a natural superfood, in a direct relationship with its botanical and geographical origin.

“…In recent years, consumers have become increasingly drawn towards organic tea products as they believe that organic tea is safer and healthier than conventional tea [ 6 , 7 , 8 ]. However, the superior market prices of organic tea relative to conventional tea increase the risk of adulteration or mislabeling [ 9 ]. Previous studies have shown that nitrogen-stable isotopes ( δ 15 N) are useful to identify organic products from their conventional counterparts [ 10 , 11 ], but the temporal change in the nitrogen isotopes in tea plants by different fertilizers is still unclear.…”

The nitrogen-stable isotopes of plants can be used to verify the source of fertilizers, but the fertilizer uptake patterns in tea (Camellia sinensis) plants are unclear. In this study, potted tea plants were treated with three types of organic fertilizers (OFs), urea, and a control. The tea leaves were sampled over seven months from the top, middle, and base of the plants and analyzed for the δ15N and nitrogen content, along with the corresponding soil samples. The top tea leaves treated with the rapeseed cake OF had the highest δ15N values (up to 6.6‰), followed by the chicken manure, the cow manure, the control, and the urea fertilizer (6.5‰, 4.1‰, 2.2‰, and 0.6‰, respectively). The soil treated with cow manure had the highest δ15N values (6.0‰), followed by the chicken manure, rapeseed cake, control, and urea fertilizer (4.8‰, 4.0‰, 2.5‰, and 1.9‰, respectively). The tea leaves fertilized with rapeseed cake showed only slight δ15N value changes in autumn but increased significantly in early spring and then decreased in late spring, consistent with the delivery of a slow-release fertilizer. Meanwhile, the δ15N values of the top, middle, and basal leaves from the tea plants treated with the rapeseed cake treatment were consistently higher in early spring and lower in autumn and late spring, respectively. The urea and control samples had lower tea leaf δ15N values than the rapeseed cake-treated tea and showed a generalized decrease in the tea leaf δ15N values over time. The results clarify the temporal nitrogen patterns and isotope compositions of tea leaves treated with different fertilizer types and ensure that the δ15N tea leaf values can be used to authenticate the organic fertilizer methods across different harvest periods and leaf locations. The present results based on a pot experiment require further exploration in open agricultural soils in terms of the various potential fertilizer effects on the different variations of nitrogen isotope ratios in tea plants.
