“…However, when the amount of acetic anhydride is increased to 6%, D [4,3], D [3,2], and D [0,5] of LS-6A were 13.53 ± 0.73 µm, 12.12 ± 0.46 µm, and 14.65 ± 0.54 µm, respectively. Especially when the acetic anhydride reached 12%, D [4,3], D [3,2], and D [0,5] of LS-6A were 18.50 ± 0.57 µm, 15.86 ± 0.55 µm, and 18.01 ± 0.66 µm, respectively. These phenomena suggested that the acylation treatment increased the particle size of the starch granules.…”

“…The particle size distribution of LSA is shown in Table 2. D [4,3] and D [3,2] represent the average diameter of volume and the average diameter of the superficial area of starch particles, respectively. D [0,1], D [0,5], and D [0,9] represent 10%, 50%, and 90% of the total number of starch particles smaller than this diameter, respectively.…”

“…In general, D [0,5] reflects the average particle size of the whole starch particle. The results indicated that D [4,3], D [3,2], and D [0,5] of LS were 10.37 ± 0.60 µm, 9.63 ± 0.50 µm, and 10.24 ± 0.68 µm, respectively. When the amount of acetic anhydride was 3%, there was no significant difference between D [4,3], D [3,2], and D [0,5] of LS-3A and LS.…”

The objectives of this study are to investigate the structural and physicochemical properties of a novel acetylated lotus seed starch (LSA). LSA is successfully prepared using an aqueous phase method. Fourier transform infrared spectroscopy (FTIR) proves that a carbonyl C=O vibration at 1737 cm−1 are due to the introduced acetyl groups. X‐ray diffraction (XRD) indicates that the acetylation treatment does not change the crystal structure, but reduces the relative crystallinity of starch. Scanning electron microscopy (SEM) shows that the surface of LSA with 12% of acetic anhydride (LS‐12A) becomes the roughest. Moreover, compared with lotus seed starch (LS), the particle size, transparency, swelling power, and solubility of LSA are increased to 18.01 ± 0.66 µm, 15.30% ± 0.30%, 9.59 ± 1.78 g g−1, and 6.06% ± 0.99% at 55 °C with the additional content of acetic anhydride. However, differential scanning calorimetry (DSC) shows that the melting enthalpy of LSA decreases compared with LS. This work provides some theoretical basis for the study and development of acetylated starch.

Despite their beneficial properties, cereal crops contain a number of antinutritive substances, the amount of which can be reduced by germination. In this work, we test the hypothesis about the possibility of stimulating the germination of cereal crops (on the example of oats and buckwheat) and increasing their digestibility using a dried Laminaria thalli extract. The research was conducted using hulless oats (Avena nudisativa) for germination and hulled buckwheat grain (Fagopyrum esculentum), as well as dried Laminaria thalli. Germination was carried out at a temperature of (20±2) °C for 120 h, using drinking water (control) and drinking water with addition of 1 wt% of dried kelp thalli. The germination intensity was assessed based on the mass of 1000 grains, sprout length, and the number of germinated grains. In all samples, the mass fraction of extractive substances and dry matter digestibility with modifications were determined. It was found that the addition of dried Laminaria thalli to water in the amount of 1 wt% stimulates the germination of oats and buckwheat, as well as their digestibility, significantly. The experimental samples demonstrated an improved water absorption and an increase in the weight of 1000 grains, sprout length, and the number of germinated grains. The use of dried Laminaria thalli extract in germination of oats and buckwheat for food purposes reduces the technological process up to two days with a simultaneous increase in digestibility and minimization of losses of extractive substances.
