“…The determination of As in rice milk has attracted attention this year, perhaps reflecting the increase in consumption, mainly by individuals intolerant to lactose or allergic to cow milk. 65 In this study, As III , As V , DMA and MMA species in rice milk were determined using LC-ICP-MS. The LOQs ranged from 0.25 to 0.43 μg L −1 As, with recoveries of 81 to 116% for samples spiked to 1.00 μg L −1 or 5.00 μg L −1 As.…”

“…In this context, the re-greening of table olives can be achieved by complexation of CDP with Cu 2+ , to form stable bright green copper CDP (Cu-CDP) complexes. To study this process a novel method was developed to separately extract lipophilic and hydrophilic Cu-CDP and quantify Cu-CDP by UHPLC-ICP-MS using post-column isotopic dilution with 65 Cu as the spike isotope. 124 Table olives spiked with Cu were prepared by boiling commercial pale yellow olives in aqueous CuSO 4 (50, 100, and 250 mg L À1 ) while table olives spiked with sodium copper chlorophyllin (SCC) were obtained by leaving table olives overnight at 20 C in 1 L of SCC solution (1000 mg kg À1 ).…”

“…Lipophilic CDP/Cu-CDP were separated with an elution gradient of (A) 0.1% HAc : MeOH and (B) 50 : 50 ACN/acetone whereas Hydrophilic CDP/Cu-CDP were submitted to an elution gradient of (A) 0.1% formic acid in water and (B) acetonitrile. The column effluent was mixed with a 65 Cu solution. Quantication of Cu-CDP in both fractions was performed by measuring the 63 Cu : 65 Cu isotope ratio although no mention is made of how mass bias was corrected for, if at all.…”

“…One of the problems when consuming rice milk is that it contains arsenic (Table 3), arsenic is a metalloid that has intermediate properties between metals and nonmetals [38]. It is a toxic substance, which in humans will depend on the dose, however, consuming small prolonged doses can cause problems in the future, so it is advisable to vary the consumption of products derived from rice to avoid exposure to arsenic [39] especially when consumed by babies and pregnant women. It is also very low in calcium and its total protein content in the rice drink is lower than that of milk proteins, therefore, it is necessary to supplement it with calcium and the essential amino acids that it lacks [32].…”

One of the areas of research and innovation of greatest interest in the food industry has been the development of new functional beverage products, specifically those that are used as an alternative to milk of animal origin, since nowadays protein allergy, lactose intolerance and other problems generated by the consumption of cow's milk, has influenced consumers to choose this type of product. Among them are Fermented Vegetable Milks (FVM) with microorganisms whose consumption has been important due to the beneficial effects on health seen in the increase in quality of life. Non-FVM lack nutritional balance compared to cow's milk, however, by fermenting them, functionally active components with beneficial health properties, also improving sensory acceptability, which is an important factor that limits their consumption and hearing. A review of five vegetable milks is carried out: soy milk, almond milk, rice milk, oat milk and coconut milk. Where studies have found that fermented soy milk offers significant benefits compared to coconut milk which provides fewer benefits. In addition to the nutritional, physicochemical and sensorial properties of FVM, mostly dependent on the raw material, the fermentation process and the microorganisms used. Research on FVM will require efforts in the coming years to prepare new and nutritionally adequate functional products.

“…The sample loop volume for conventional chromatography column is generally more than 100-200 μL (Son et al 2019;Rosa et al 2019;Nogueira et al 2018). The amount of sample required for analysis using this sample loop is typically 0.5-1.0 mL or more.…”

Quantitation and speciation of inorganic arsenic in a biological sample by capillary ion chromatography combined with inductively coupled plasma mass spectrometry

The toxicity and biological activity of arsenic depend on its chemical form. In particular, inorganic arsenics are more toxic than organic ones. Apart from the determination of total arsenics, their accurate speciation is important for toxicity assessment. To separate arsenic species using a cation or an anion separation column, at least 0.5–1.0 mL of sample is required because conventional ion chromatography columns use a sample loop of 100–200 μL. It is thus difficult to analyze samples with small volumes, such as clinical and biological samples. In this study, a method for separating arsenic species using a 5-μL sample loop combined with a capillary ion exchange column has been developed for analyzing small volume of samples. The separated arsenics were determined by inductively coupled plasma mass spectrometry. By oxidizing As(III) to As(V) prior to analysis, the total inorganic arsenics, As(III) and As(V), could be well separated from the organic ones. Linear calibration curves (0.5–50 μg/kg) were obtained for total inorganic arsenics dissolved in water. Sub-picogram-level detection limit was obtained. The analytical capability of this method was successfully validated for certified reference materials, namely water and human urine, with total inorganic arsenic recovery efficiencies of 100% and 121%, respectively. Our method requires less than ~ 10 μL of sample and will be very useful to analyze valuable samples available in limited amounts.
