This work describes the bioaccessibility in vitro simulated gastric digestion for levels of Zn, Ca, and P in milk and soybean extract samples. Total and dialyzed levels were determined by ICP OES. According to results of the dialyzed samples, it can be concluded that in 250 mL of milk (a glass) the body can be absorb about 1.2 ± 0.2 mg, 14.8 ± 1.2 mg, 4.5 ± 0.8 mg, 2.2 ± 0.4 mg and 4.9 ± 0.6 mg of Zn; 2079 ± 133 mg, 305 ± 4 mg, 2396 ± 16 mg, 2444 ± 54 mg, and 1527 ± 71 mg of Ca; and 2023 ± 275 mg, 811 ± 14 mg, 2688 ± 39 mg, 5089 ± 474 mg and 3467 ± 63 mg of P for raw sheep’s milk, soybean, raw cow’s milk, UHT goat’s milk, and UHT cow’s milk, respectively. These results correspond to approximately 45, 118, and 267% of diary human needed of Zn, Ca, and P, respectively. Accuracy was verified using CRM (NIST 8435) for total levels, and dialyzed samples were compared with FAAS, statistically evaluated by Student’s t-test. Results confirmed the methodology efficiency and allowed an estimate of the bioacessibility of nutrients. (AU) | |
