“…Lecithin exhibits a concentration optimum for viscosity and yield stress reduction, whereas, for PGPR and YN, yield stress and equilibrium viscosity decrease with increasing emulsifier concentrations (Chevalley, ; Schantz et al ., ; Schantz & Rohm, ). The emulsifier concentrations were adjusted to fulfil the legal specifications for confectionery applications (5 g kg −1 for PGPR; Afoakwa (), and 10 g kg −1 for YN; Norn ()), or to follow a previous study (4 g kg −1 for soybean lecithin; Schantz & Rohm ()), with regard to the final product. Assuming that the emulsion accounts for 30% of the final product, for example a confectionary product that serves as the basis for a chocolate drink, the experimental concentrations were adequately increased.…”

Summary In a first step of designing tailored confectionery masses using water‐in‐oil emulsions, a parameter screening on emulsion rheology and stability was carried out. The experimental set‐up included cocoa butter as continuous phase and the variation of the disperse phase (water, or 50% sucrose in water), two volume fraction levels and the type of emulsifier (lecithin, polyglycerol polyricinoleate (PGPR), ammonium phosphatide (YN) and blends of lecithin or YN with PGPR). Emulsions were characterised by microscopy, laser diffraction, analytical centrifugation and shear rheology. Results show multimodal droplet size distributions in lecithin‐ or YN‐stabilised emulsions, and droplets which tend to form aggregates and an internal network responsible for shear thinning. PGPR emulsions are characterised by monomodal droplet size distributions and smaller droplets without networking tendency. They exhibit Newtonian flow behaviour and a much higher stability against phase separation. In emulsifier blends, PGPR is mainly responsible for the modulation of physical properties of the emulsions.

“…The physical appearance depends on the source of the fatty acid moiety. The presence of fully saturated fatty acids results in a product with a melting point above 50°C, while the presence of unsaturated acids yields soft or liquid ammonium phosphatides with a melting point below 40°C (Palsgaard, 2007 [Documentation provided to EFSA n. 4]; Norn, 2015).…”

“…canola oil, sunflower oil, maize oil (Anon, 2002). According to Norn (2015), today low erucic acid rapeseed oil like canola and other non-erucic oils are used for the manufacturing of ammonium phosphatides. Bradford (1976) and Palsgaard (2007 [Documentation provided to EFSA n. 4]) described the manufacturing of ammonium phosphatides by referring to a five-step process: in a first step, by a glycerolysis reaction under an inert atmosphere, a triglyceride is heated (temperature > 200°C) with glycerol to produce an equilibrium mixture of mono-, di-and triglycerides with an optimum yield of diglycerides.…”

The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion re-evaluating the safety of ammonium phosphatides (E 442) as a food additive. The Scientific Committee on Food (SCF) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) allocated an acceptable daily intake (ADI) of 30 mg/kg body weight (bw) per day in 1978 and 1974, respectively. The Panel noted that after oral administration of E 442 ([ 32 P]YN), a proportion of the radioactivity passed through the gastrointestinal tract and was excreted via faeces and also a quantity of radioactivity was absorbed rapidly after dosing as indicated by its presence in the skeletal tissue and liver. Acute oral toxicity of ammonium phosphatides is low and no adverse effects were observed in a 90-day rats study. The Panel considered that ammonium phosphatides did not raise concern for genotoxicity. The Panel identified no observed adverse effect levels (NOAELs) of 8,500 and 3,000 mg/kg bw per day, the highest doses tested, from dietary chronic and carcinogenicity studies with ammonium phosphatides in mice and rats, respectively. No effects on reproduction and development were observed in a dietary two-generation reproductive toxicity study at the only dose tested of 3,000 mg/kg bw per day, and in addition, no maternal or developmental effects were recognised in a dietary prenatal developmental toxicity study up to a dose of 4,774 mg/kg bw per day. Based on the available toxicological database, the Panel concluded that there is no reason to revise the current ADI for ammonium phosphatides of 30 mg/kg bw per day. Considering that the ADI is not exceeded in any population group, the Panel also concluded that the use of ammonium phosphatides (E 442) as a food additive, at the permitted or reported use and use levels, would not be of safety concern.

We study the evolution of the mass of evaporating single microdroplets of sodium dodecyl sulphate (SDS) / diethylene glycol (DEG) mixture. First, we recognise and deconvolute the influence of residual water evaporation [Kolwas et al. Soft Matter 2019;15:1825], which accelerates the composite droplet evaporation, a simple exponential decay of the evaporating droplet surface change rate. This enables us to study the influence of SDS concentration on the composite droplet evaporation. Next, we establish a simple relationship between the average SDS concentration and the droplet evaporation rate to enable the study of the evolution of SDS concentration at the droplet surface. The oscillatory nature of surface SDS concentration indicates cyclic changes in the surface monolayer associated with the cyclic creation of vesicles (micelles) at the surface. The model we developed, allows determination of SDS critical micelles concentration (CMC) in DEG as 60±2 mM.
