Plant enzymes sources as protecting factors for human organism against stress and environmental pollutants induced disorders

Enzymes, notoriously known today for their importance in the normal functioning of the entire
organism, are affected by changes of the natural environment through excessive chemisation
of soil, water, air, and subsequently, food. Inadequate dietary, based mainly on industrially
processed preparations have acquired more significance even in Romania, were traditional
food was of high importance. As a result, in association with other factors, such as daily stress,
lack of exercise, continuous rush, etc., it has led to obesity, which in turn generates serious
diseases (diseases of the digestive system, diabetes, cardiovascular disease, etc.).
The authors, driven by the desire to provide new products enriched in fibers and vegetal
enzymes, have studied several plants and plant organs, as potential sources of enzymes.
Some of the studies relate to leafs of Aloe (Aloe vera), cabbage (Brassica oleracea), sea
buckthorn (Hippophae rhamnoides), that have proven representative for the recalled purpose.
The following trials have emphasized the importance of this plant material for the production
of dietary supplements containing increased enzymes content, of which mainly are digestive.
From the class of Hydrolases, also called ‘digestive enzymes’, amylase, lipase and protease
were investigated. From the class of Oxidoreductases with role of neutralizing free radicals
generated by the oxidative stress the most representative were revealed: SOD and catalase.
The selected plants were found to hold especially high intakes of digestive enzymes that are
useful in various combinations to balance the digestive system, ensuring complete and
accurate digestion of food, the main way to maintain and improve health.
