Culinary Herb

The Pinaceae family has traditionally been used as medicine, resorted to as a famine food and for ornamental purposes as Christmas trees. In the last few years numerous restaurants have been using different species of Pinaceae family as a garnish or an aromatic spice, using them in different culinary applications like oils and infusions to flavor dressings and broths. Abies grandis (Grand fir), Pseudotsuga menziesii (Douglas fir), Pinus sylvestris (Scots pine) and Picea abies (Norway spruce) were researched on taxonomy, habitats and non-edible uses, culinary traditions, health and nutritional properties, aroma profile. The main compounds in Pinaceae family are monoterpenes, oxygenated monoterpenes, sesquiterpenes, oxygenate sesquiterpenes, diterpenes and hydrocarbons, especially α-β-pinene, limonene, α-terpinene, and even bornyl acetate, responsible for aroma compounds such as citrusy-, woody-, herbal-, or piney aromas. Modern gastronomy uses, sensory analysis and culinary applications were applied for demonstrating the possibilities on modern culinary application in this novel yet traditional spice.

The Stability

The presented study summarizes the results concerning the effects of cultivation of Douglas-fir (Pseudotsuga menziesii (Mirbel) Franco) in the Czech Republic. It focuses on more recent results, published especially in the last decades, it includes also older relevant data. It describes the intensity of production as well as non-production forest functions in the conditions of the Czech Republic. It analyses the research results concerning the volume and value production in comparison with native tree species, also documents effects on soil and herb vegetation diversity in forest ecosystems, and from point of view of stability and cultivation in the last period. Main target is defined by the comparison with the Norway spruce, which can be with advantages substituted partly by this species, with favourable impact on amount and value of the timber production, on the forest soil and ground vegetation biodiversity status. Also the stability of forest stands can be supported considerably. This species represents important alternative to the Norway spruce in lower and middle altitudes and it can contribute considerably to the competitiveness of the Czech forestry.
