Abstract
Mineral elements are essential micronutrients necessary to constitute human tissue and maintain normal physiological functions. Micronutrient deficiencies are an important issue currently faced in the world. The best strategy to solve this problem is to breed special functional types of rice varieties rich in trace elements (special rice for short). A special type of rice that can produce rich nutrients. In order to explore the nutritional value of giant embryo rice, the contents of 17 mineral elements ((K, Ca, Fe, Se, Zn, Cu, Na, Mn, Mg, Ni, Cr, Co, Pb, As, Cd, Ag, Al)) in 5 kinds of giant embryo rice (white giant embryo, giant japonica-GB-12, giant japonica-GB-11 and giant japonica-GB-5, giant japonica-GB-1) were detected by inductively coupled plasma mass spectrometry. After comparison with ordinary rice, it was found that the content of the same mineral element in different samples has a large variation, suggesting that different rice varieties have different absorption, transformation and storage efficiency of the same element; different giant embryo brown rice in some mineral elements (such as Cr, Ni, Cu and Zn) are extremely low in content and almost undetectable. Meanwhile, the brown rice of giant embryo rice has a more powerful enrichment effect on some mineral elements, which means that embryo rice has a unique advantage in cultivating new rice varieties with special functions rich in minerals.
Highlights
Crude oil, a naturally occurring unrefined petroleum product composed of hydrocarbon deposits and other organic materials
This study showed that various important chemicals/compounds useful in traditional medicine and for industrial uses are present in crude oil, thereby making it a good raw material for industrial and medicinal purposes
Some of the chemical constituents detected may be used for various purposes such as production of fuel, pesticides, some volatile compounds, fragrance, food additives and antimicrobial agents
Summary
A naturally occurring unrefined petroleum product composed of hydrocarbon deposits and other organic materials. Crude oil can exist in several forms such as aliphatic, alicyclic and aromatic compounds. Most of these compounds when exposed to at a given lethal dose are known to be toxic to different biomass in the ecosystem [1, 2]. Crude oil is orally ingested for medicinal purposes. The ingestion of crude oil either orally or through polluted marine species represents a pathway for delivery of potential toxicants to the human system. Local population has used crude oil or its fraction for the treatment of various ailments such as gastrointestinal disorders, burns, foot rot, leg ulcer, poisoning and even witchcraft and is mostly administered orally [8, 9]
