Fast Sequential Determination of Zn, Fe, Mg, Ca, Na, and K in Infant Formulas by High-Resolution Continuum Source Flame Atomic Absorption Spectrometry Using Ultrasound-Assisted Extraction

WITHDRAWN: Rapid quantitative analysis of calcium in infant formula powder assisted by long short-term memory with variable importance using laser-induced breakdown spectroscopy

“…As a result, several methods have been proposed for detecting whether the composition of INF meets the requirements of the standard [8 -10]. There are many traditional methods for measuring the content of calcium and other minerals in dairy products, such as ame atomic absorption spectrometry (FAAS), inductively coupled plasma optical emission spectrometry (ICP-OES), and inductively coupled plasma mass spectrometry (ICP-MS) [11][12][13]. Although these technologies are mature and have high sensitivity and accuracy [14], they all require sample preparation processes and the use of toxic chemicals.…”

The use of ultrasound in the South Cone region. Advances in organic and inorganic synthesis and in analytical methods

“… Bath-type ultrasound-assisted extraction (BUAE) was the best technique to obtain lycopene [96] Zn, Fe, Mg, Ca, Na, and K Infant Formulas UAE ES: HNO3 2.1 mol L − 1. 0.250 g of infant formula sample, 20.0 mL ES, sonicated Unique, São Paulo, Brazil) operating at 37 kHz for10 min at 80 °C use of ultrasound bath increased the best sample throughput [97] Daidzein and Genistein (isoflavones) Soybean UAE ES: ethanol 0.5 g of sample (previously defatted) and 25 mL of ES in an ice bath and sonicated UP (4 mm, 500 W, 40 kHz, 20 min). Centrifugation at 9070 g for 10 min at 10 °C High amounts of isoflavones Ultrasonic waves reduce the analysis time.…”

“… [96] used an ultrasonic bath instead of a probe because the cavitation intensity was lower, and they could achieve a higher efficiency in the extraction of carotenoids, with a less degradation of this analyte. Besides, some authors reported that the use of ultrasound baths allowed them to examine several samples simultaneously [97] . Nevertheless, da Silva et al .…”

Analytical advances in the determination of calcium in bovine milk, dairy products and milk-based infant formulas

“…Figures of commercial samples fitted well (at 95% confidence level) with those recorded by conventional wet digestion sampling and were judged in agreement with literature data. Recently, Gamela et al (2019) by HR-CS FAAS determined calcium and other minerals in commercial MIF by using ultrasound-assisted extraction. Slurry of samples by mixing with HNO 3 was agitated by ultrasonic device operating with a frequency of 37 kHz at a temperature of 80 °C for 10 min.…”

“…The application of ultrasound is normally combined with the use of acids or H 2 O 2 to intensify the sonication power. The ultrasound-assisted extraction was successfully employed to determine the presence of micro-and macro-minerals in MIF, and it resulted in a reduction of acid consumption and sample preparation time (Gamela et al, 2019).…”
