n.d., not detected. 1 Results are expressed as the mean ± standard deviation (n = 4). This came from obtaining at least two independent digestions (n = 2) and performing the determinations of each two times (n = 2). Superscript letters indicate statistically significant differences of specific bioaccessibility of each compound evaluated (p ≤ 0.05) between HHP treatments.
