Abstract:

The aim of current research was to assess the nutritional value of breakfast cereals containing germinated spring grain flakes and its changes after 6 month storage. Three types of breakfast cereals were prepared and packaged in two types of Standup pouches – Pap50g/Alu7/Pe60 (AL), Pap40g/PELD20/PE40 (PE). For the accelerated shelf life test the samples were stored at 35 ± 2 °C and dietary fibre, protein, fat, B-group vitamins, sugars, total phenol content and DPPH, ABTS+ radical scavenging activity were determined. Developed breakfast cereals have high nutritional value and all are high in fibre and thiamine. Additionally, sample S2 is source of protein, riboflavin, niacin, and S3 – is source of riboflavin and high in niacin. Comparing total phenolic content and antioxidant capacity of tested samples S3 showed the highest values. Storage and selected packaging influenced stability of nutrients, and for S1 and S2 AL showed better results whereas for S3 – PE.

Abstract:

Weeds were investigated in the stands of field pea (Pisum sativum L.), barley (Hordeum vulgare L.), wheat (Triticum aestivum L.), oat (Avena sativa L.) and triticale (Triticale hexaploide Lart.) grown as pure and as mixtures at the Lithuanian Institute of Agriculture. Results revealed that annuals dominated in the weed flora composition (7–19 species) while perennials were more recessive (2–11 weed species). The total weed number was higher by 1.3–1.6 fold in the peas stand compared to the weed number in peas-cereals stands. In barley, wheat, oat and triticale stands the number of weeds was significantly lower than that for peas. Cereals and their mixtures with peas had the best suppressing ability compared to peas investigated. The dry mass of weeds in the peas stand was essentially higher than in the other stands of crops. The effect of pea mixtures with cereals crops on weed mass was similar as compared to that of pure cereals crops.
