## 3 Results and Discussion  
The yield, basic chemical composition and molecular properties of fenugreek and sweet basil seed hydrocolloid (non-starch polysaccharide) preparations are shown in Table 1.  
The yield of hydrocolloids obtained from milled fenugreek seeds by extraction with water at 70 \({}^{\circ}\)C was higher (\(p<0.05\)) than by extraction with water at room temperature (Table 1). However, the yield of hydrocolloids obtained from milled sweet basil seeds was comparable for both preparations, regardless of the extraction temperature used (Table 1). The yield of hydrocolloids extracted with water at room temperature from milled fenugreek seeds (PERT) was similar to data in the literature, where the yield of hydrocolloids by water extraction with ultrasound was 25.10-33.75% [8]. On the other hand, the yield of hydrocolloids extracted with water at 70 \({}^{\circ}\)C from fenugreek seeds (PF70) was higher than the yield presented in the literature [7]. The differences in the results were likely due to the use of different batches of raw material, the degree of milling, as well as differences in the extraction and purification process of the preparations. The yield of hydrocolloids extracted from sweet basil seeds (PSBRT and PSB70) was about 41% (Table 1). Previously, only polysaccharides were extracted from whole basil seeds with yields ranging from 2.1% to 18.0% [13; 15; 16; 17]. It should be noted that [PERSON] et al. [16] showed that the yield of polysaccharides extracted from sweet basil seeds was affected by pH, temperature and the ratio of seeds to water. Both preparations obtained from milled fenugreek seeds PERT and PF70 were characterized by a similar composition of sugar residues released after acid hydrolysis (Table 1), as the preparations contained mainly galactose, mannose and glucose, as well as small amounts of xylose and arabinose, which was consistent with data presented in the litera \begin{table}
