Changes in molecular weight of LDSPs during in vitro digestion and fermentation.
| Samples | Peak 1 | Peak 2 |
|---|---|---|
| Mw (Da) | Mw (Da) | |
| LDSPs | 4.59× 107 ± 0.04a | 4.30 × 106 ± 0.15a |
| LDSPs-S | 4.52× 107 ± 0.12a | 4.25 × 106 ± 0.09a |
| LDSPs-G | 4.46× 107 ± 0.23a | 4.21 × 106 ± 0.19a |
| LDSPs-I | 4.41× 107 ± 0.09a | 4.19 × 106 ± 0.13a |
| LDSPs-6 h | 4.08× 107 ± 0.14b | 3.96 × 106 ± 0.18b |
| LDSPs-12 h | 3.37× 106 ± 0.16c | 3.55× 105 ± 0.09c |
| LDSPs-24 h | 2.35× 106 ± 0.10d | 2.03× 105 ± 0.24d |
Data are expressed as mean ± SD (n = 5), and a–d mean significantly different (p < 0.05) by a Tukey test in the same group with different time points. LDSPs-S, LDSPs-G, and LDSPs–I: samples of LDSPs digested after different digestion fluids in vitro, including salivary, saliva-gastric, and saliva-gastrointestinal digestions, respectively; LDSPs-6, LDSPs-12, and LDSPs-24: LDSPs fermented by human fecal microbiota at different fermentation time points of 6, 12, and 24 h, respectively.
