A browning composition is prepared by mixing an oil phase containing an emulsifier with an aqueous phase containing a colorant under shear conditions to form a dispersion of the aqueous phase in the oil phase.

Process for preparing a browning composition

There is disclosed a browning composition for uncooked foods comprising a colorant and a fat or an oil. Also disclosed is a process for imparting a brown color to cooked foods by using the composition of the present invention on foods cooked, for example, in a microwave oven.

Browning composition and process for browning foods

Aqueous gel-forming compositions are prepared by reacting for 1-10 hours at 50.degree.-95.degree. C., melamine, formaldehyde and a sulfurous acid salt with the optional addition of a gel-modifying agent and/or a gelling agent which is added to the composition immediately prior to use.

Hydrocarbon recovery from subterranean reservoirs that are penetrated by either injector or producer wells is enhanced by selective permeability modification of the strata of the reservoir with gel-forming phenolic compositions. The injection of the phenolic composition follows a pH sequence specific to the reservoir environment which allows emplacement of the gel-forming composition the desired distance away from the wellbore and production of a uniform gel throughout the treated hydrocarbon-bearing reservoir. The permeability of a treated subterranean reservoir can be restored by treatment of the reservoir with either aqueous hypochlorite or mineral acid.
