Animal fat in all‐chicken frankfurters (control) was replaced with pretreated linseed oil to provide 50 and 100% of recommended daily alpha‐linolenic acid intake. Linseed oil was pretreated with multifunctional corn ingredient (E25 and E50) and alginate mixture (G25 and G50). No impairments in water binding properties of the modified frankfurter matrix were observed. Significant increase in b* and h values was observed, intensively in G treatments. Significantly higher hardness was observed in E25 and chewiness in both E treatments. During storage, an increase in yellowness, hardness, cohesiveness, and chewiness was recorded in all treatments including control. Significant improvement of fatty acid profiles was recorded in all modified frankfurters. Observed differences in some parameters of technological characteristics were not confirmed in sensory evaluations. The results of sensory analysis indicate that the level of fat replacement with linseed oil and the manner of pretreatment did not lead to unacceptability. Practical applications Frankfurters are well‐known comminuted meat products usually made from pork and beef, but despite a considerable increase in poultry meat production over the past two decades, research on all‐poultry frankfurters with fat partly replaced by pretreated oil are rare. The results of this current study showed that all‐chicken frankfurters with 50% of recommended daily intake of ALA had very similar characteristics to control, while increasing content of linseed oil (to 100%) potentially can impair sensory characteristics, depending of oil pretreatment, but not below the acceptability. Since data in literature are scarce in terms of all‐chicken frankfurters with fat partly replaced by pretreated oil, the results of this research complement the results of the research on pork and beef frankfurters and the results of the study on the use of linseed oil in other meat products.

We report the results of an Ar I and Ne I line shape study in an abnormal glow discharge operating in argon and neon. The spectral lines were observed along the axis of a cylindrical glow discharge parallel (side-on) and perpendicular (end-on) to the cathode surface. The side-on spectra show spectral line shifting and sometimes simultaneous shifting and splitting in the cathode fall region of the glow discharge. The results of the measured line shift with available data for the dc Stark effect are used for measurement of electric field strength in the cathode fall region of the glow discharge. Electron temperatures of 2860 K and 4770 K in the negative glow region of argon and neon discharges, respectively, were determined from the relative intensities of Ar I or Ne I lines using the Boltzmann plot technique. An electron number density of ≈10 20 m −3 (±25%) in the negative glow region of the argon discharge was determined from the widths of two plasma-broadened Ar I lines using theoretical Stark broadening data. The end-on recorded line profiles show 10-40% larger half-widths than the side-on recorded line profiles from the negative glow. This effect is a result of the superposition of line emission in the cathode fall region under the influence of the dc Stark effect on the line profile from the negative glow.

We report the results of five Ne i line shapes study in an abnormal Grimm-type glow discharge operating in neon.
