Both, the bakery properties and sensory evaluation a conventional tillage system bread were higher. The addition of 1-moll lactic acid to bakery...
The investigation aimed at analyzing the variability in winter wheat cultivars yielding as depending on the tillage system, density and term of sowing. There were used two systems of tillage: conventional (plughing) and simplified. In each of them regarded were the following factors: I – terms of sowing: a) 14–16 September (early sowing); b) 1–3 October (optimum sowing); 15–17 October (delayed sowing);...
There was examined the influence of citric acid (in concentrations of 0.5 and 1%) and ascorbic acid (in concentrations of 0.025 and 0.05%) on changes in colour of sterilized (118 and 121ºC) vegetable pulps. Obtained results of colour objective estimation (verified statistically) displayed that the addition of citric and ascorbic acids caused significant changes in colour parameters L*, a*, b*. The...
