The main hypothesis that organically grown products

comparing with intensive technology are more

accumulated biological active subctances has been

confirmed when the disertations were defended during

the 2007 -2017.

The main hypothesis that biodynamic preparations could improve

the soil biological and agrochemical properties has been confirmed

when three dissertations (authors dr. E. Juknevičienė, dr. N.

Vaitkevičienė, dr. D. Levickienė) were defended in 2015, 2016 and

2018.

As a result the application of these preparations during the cultivation for the

accumulation of biocompounds and their antioxidant activity was

increased in the pumpkin fruits as well in potato with pigmented flesh.

Heavy metals residues

photo MsC. L.Neverauskaitė

Heavy metal concentrations in the skin, flesh and seeds of the analysed

pumpkin fruits did not exceed the maximum permissible concentrations

established by the EU norms

The objective of this study has been to compare the

accumulation of heavy metals in different parts of oilseed

pumpkin fruit depending on the chemical composition of

the compost the pumpkin plants had been supplied..

Heavy metals residues

INNOVATIVE PROCESSES FOR

OPTIMIZING OF QUALITY NEW FOOD

PRODUCTS

Amarantus (Amaranthus cruentus L.)

Amaranth’s balanced amino acid composition is close to the optimum

protein reference pattern in the human diet according to FAO/WHO requirements .

- The biological value of amaranthus protein is equil to 75% (as well the

protein of corn -44%, soya-68%, milk-72%) .

Jerusalem artichoke (Helianthus tuberosus L.)

The Jerusalem artichoke is known as resource of not only

valuable carbohydrates and amount those inulin but also in non-essential amino acids .

Jerusalem artichoke accumulated the highest amount of nonessential glutamic and aspartic amino acids. In Jerusalem artichoke tubers dominated - arginine in the essential amino acids group.

PUMPKINS (Cucurbita maxima L.)

The pumpkin tissue contains saccharine, high quality of protein and fibre,

are potentially excellent raw materials that might contribute to an increase for important nutrients not usually found in convenience foods.

Pumpkin pulp accumulated the highest amount of nonessential glutamic and aspartic amino acids, as well dominated leucine and valine.

The process of drying Jerusalem artichoke tubers and making to flours for following their biochemical

investigations
