HoweverSiO2/PAM nanocomposites tend to agglomerate or even desposit under harsh conditions such as high temperature-high salinity (HT-HS)which greatly decreases the potential for future field applications. In this workSiO2 NPs were modified by (3-aminopropyl) triethoxysilane (M_SiO2) to create positively charged active groups that enabled strong interaction with PAM functional groupsleading to high dispersion stability.

NATURAL CREAMER WITH HIGH TOLERANCE TO ACIDITY AND MINERALS IN BEVERAGE AuthorRousset, Philippe; Saffon, Maxne; Steffes, Peter; Fu, Xiaoping Year2020 SourceUnited States Patent Application 20200236981 LanguageEnglish 2284The creamer of claim 1wherein the ratio of proteins: fat is greater than 1:25; and wherein the Lumisizer instability index is less than 40. foodnutrition 26 more LSSOCIETE DES PRODUITS NESTLE S.A.In an embodiment the Lumisizer instability index is less than 40. For a powdered creamer it is understood that the creamer is reconstituted with water for this measurement. The creamers in embodiments of the present disclosure demonstrate a pH ranged from 5.2 to 10. A preferred pH of 5.2 to 10more preferred 6 to 9and even more preferred 7 to 7.5 is needed to neutralize the acids from coffee (e.g. a medium roasted 100% Columbian Arabic coffee) or other beverages. It is known that acidity causes emulsion to coalescence or aggregate or curdling. pH of creamer also impacts on the creamer physical stability and shelf-life. For the creamer with the most preferred pH ranged from 7 to 7.5it was most stable; while creamer shows a physical instability during its shelf life when pH is below than 6 as indicated by lumisizer data. As used hereinthe term “stable” means remaining in a state or condition having no phase separation (e.g.creamingsedimentationand/or age gelation) or spoilage or bitterness (e.g.due to storage) for an extended period of time up to 9 months at refrigerated conditions (e.g.about 0.5˜7.2° C.). MoreoverLumisizer instability index is less than 40 (FIG. 4). The Lumisizer (LUMGermany) Model 611 was used to evaluate the stability against creaming. Lumisizer (LUMGermany)is an instrument using light scattering detection under sample centrifugation. It is especially designed to assess different separation phenomena based on oil droplet creaming or particle sedimentation occurring in oil-in-water emulsions and dispersions. In the Lumisizerthe so-called STEP technology (Step and Time resolved Extinction Profiles) is used. The samples were measured without dilution and centrifugal forces were exerted up to 2 hours at 20° C. and 2300 g force. The transmission profiles of samples were taken every 20 sec. From the raw transmission profilesthe integral of transmission over time is calculated and its slope (named an Instability Index) was used as a quantitative measure for emulsion instability against creaming. Separation graphs shows movements of the interface between the dispersed phasei.e. the movement of emulsion layersand the clear phaseas a function of time. The difference in separation rates (Instability Index) between the samples allowed to assess relative stability of emulsions against creaming. The integral transmission (T) was plotted as a function of time (t)and the slope (ΔT/Δt) was calculated. A higher slope (Instability Index) indicates a faster separation and thus a less stable product. Natural Creamers for providing whitening and indulgent texture/mouthfeel of beverage and food products are provided. The creamers have long-term stabilityhigh whitening capacity and a pleasant mouthfeel when added to beverage and foodwhile being free from artificial additives the creamers comprising plant oil and plant proteinsand being further characterized in that the creamers comprise baking soda and citrus fruit juice concentratewherein the citrus fruit juice concentrate comprises acid component comprising citric acid and malic acid.
