Are hemp seeds cold pressed?

Hemp seeds are usually transformed into flour or oil; in order to obtain an oil with higher nutritional and sensory qualities, hemp seeds are commonly cold-pressed. Cold pressing is a technology that does not involve the use of heat treatment or solvent (Codex Stan 210-1999; Lutterodt et al., 2010).

Does cold pressed soybean oil contain trans fatty acids?

However, Brühl (1996) detected the presence of trans fatty acids (0.10%¨C0.15%) in cold pressed soybean oils. The author thus stated that trans fatty acids may occur due to high temperature drying of seeds before cold pressing and/or deodorization of cold pressed soybean oils or blending of cold pressed oils with refined ones.

Does cold pressed hemp seed oil oxidize?

An ¡°oxidative wave¡± was observed without a subsequent degeneration of the oil. The oil, stored for 3 months in a dark-light cycle, did not significantly oxidize. Several analytical parameters were evaluated to investigate changes in the composition of a cold-pressed hemp seed oil over a period of 3 months of storage.

How is hemp seed oil obtained?

2.1. Samples Hemp seed oil was obtained by cold pressing of hemp seeds (Futura 75 variety), dried and not skinned, using a screw press with 20 kg/hour capacity (Plus model, engine power of 3.0 kW, rpm 15¨C70, voltage 400 V 3-ph, dimensions 480 × 480 × 620 mm, and weight 145 kg) supplied by Tecnoimpianti Srl (Ospedaletto Euganeo, Padua, Italy).
