Potassium sorbate is the potassium salt of sorbic acid, is a widespread and efficient antioxidant that has multiple functions in plants, traditionally associated with the reactions of photosynthesis; however, it has moderate toxicity to various species including rat, fish, bacteria and human health. The effects of potassium sorbate on the movement and photosynthetic parameters of Euglena gracilis were studied during short-term exposure. Potassium sorbate showed acute toxicity to the green flagellate E. gracilis affecting different physiological parameters used as endpoints in an automatic bioassay such as motility, precision of gravitational orientation (r-value), upward movement and alignment, with mean EC50 values of 2867.2 mg L−1. The concentrations above 625 mg L−1 of potassium sorbate induce an inhibition of the photosynthetic efficiency and electron transport rate and, in concentrations more than 2500.0 mg L−1, the Euglena cells undergo a complete inhibition of photosynthesis even at low light irradiation.
Further exploitation of PDB method led to identification of four new dithiolopyrrolone antibiotics, crotonylpyrrothine 31, sorbylpyrrothine 32, 2-hexenylpyrrothine 33 and 2-methyl-3-pentenylpyrrothine 34, in the presence of 5 mM sorbic acid in the production medium, showing the remarkable flexibility of the dithiolopyrrolone biosynthetic pathway in S.

In controlled studies in children, the incidence of adverse reactions to preparations containing annatto was much lower than previously described in adults, or was nonexistent. A study in Denmark in which 271 children (98 controls and 173 with atopic symptoms) underwent open oral challenges to a variety of food additives prepared in a lemonade solution, 17 children had positive reactions. The additives included preservatives, natural colours, synthetic colours, flavourings and acids. Twelve of the 17 children then underwent double-blind placebo-controlled challenges to the additives prepared in gelatine capsules. Of the 12, five reacted to the synthetic food colourings and one reacted positively to citric acid, but none reacted positively to the natural food colourings capsule which contained turmeric (2.5 mg/100 ml), annatto (1.6 mg/100 ml), carotene (6.0 mg/100 ml), canthaxanthine (1.0 mg/100 ml) and beet colouring (5.5 mg/100 ml) (Fuglsang et al., 1993).
® is one of the most sold brands of CLA.
The application of CLA-producing bacteria for the synthesis of CLA in foodproducts is a challenging opportunity which is the aim of many investigations ().
Besides these C18 acids there is a shorter chain compound, sorbic acid.
Sorbic acid, or 2,4-hexadienoic acid, was first isolated in 1859 by AW vonHofmann from the unripe berries of the Rowan ().

The question of the possibility of these plant fatty acids to be the precursors of the long-chain n-3 compounds (EPA and DHA) in transgenic plants has been examined (, ). Recent progress demonstrates the feasibility of using transgenic plants to synthesize long-cain polyunsaturated fatty acids.
The main source of n-3 fatty acids is fish oil but the market prices of that product are increasing significantly.
