Elaidic acid is the 9-trans isomer of oleic acid. It is a monounsaturated trans-fatty acid, which can be found in partially hydrogenated cooking oils. It was revealed, that elaidic acid inhibits HHT and HETE formation in human platelets incubated with arachidonic acid. Also was shown, that trans oleic acid increased plasma CETP activity, which increases low-density lipoprotein (LDL) cholesterol and decreases high-density lipoprotein (HDL).

2-Hexenal belongs to the aldehyde and exists in two isomeric forms: cis (Z) and greater importance form, trans (E). Trans-2-hexenal was studied as a potential antifungal compound that can inhibits Aspergillus flavus Spore Germination. The inhibition takes place by the disruption of mitochondrial energy metabolism and the induction of early apoptosis. Besides, trans-2-hexenal can be an alternative fumigation agent for controlling M. incognita on tomato crops. Botanical nematicides have recently received increasing interest because of the high risks of some traditional nematicides to human health and the environment.

Erythorbic acid, an epimer of L-ascorbic acid, is used in the United States as a food additive. It was studied, that erythorbic acid enhanced of iron absorption and could play a major role in enhancing iron bioavailability from mixed diets that include foods preserved with erythorbic acid. In addition, was investigated if the erythorbic acid could influence on the metabolism of vitamin C in young women, and obtained results showed, that prolonged ingestion of erythorbic acid had no effect on vitamin C uptake or clearance from the body.

Amaranth is an artificial dark red to purple azo dye. It is also used to color cosmetics. Amaranth is commonly used in fish roe, aperitif wine drinks and Americano. It has been banned in the United States since 1976 by the FDA, because it is a suspected carcinogen. Amaranth (E 123) is an azo dye authorised as a food additive in the EU and has previously been evaluated by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) in 1972, 1975, 1978 and 1984, and by the EU Scientific Committee for Food (SCF) in 1976, 1979 and 1983. Derived from the small herbaceous plant of the same name. A purplish-red (blackcurrant) synthetic coal tar or azo dye found in ice creams, gravy granules, jams, jelly, tinned fruit pie fillings and prawns and packeted cake mixes, soups and trifles. It appears to cause allergic and/or intolerance reactions, similar to nettle rash, particularly amongst those with an aspirin intolerance or asthmatics. can provoke asthma, eczema and hyperactivity; it caused birth defects and foetal deaths in some animal tests, possibly also cancer. Not recommended for consumption by children. It is banned in Norway, United States, Russia and Austria with a very restricted use in France and Italy (caviar only).
