The present invention relates to color and shelf stable beverage compositions comprising:

Color and shelf stable beverage compositions containing tea extract

A process for the production of tea extracts is disclosed comprising the steps of (a) extracting tea materials with water, (b) mixing the extract containing solution with protein, (c) acidifying the protein containing extract, and (d) separating the precipitates formed. The resultant tea extracts have reduced bitter and astringent flavors and low levels of polymerized or oxidized flavanols. The extracts are suitable for use as beverages or can be blended with fruit flavors, fruit juices and other flavors.

Tea extract and process

A process for the production of green tea extracts is disclosed comprising the steps of (a) extracting tea materials with an acidified aqueous solution comprising erythorbic acid or ascorbic acid and citric acid and mixtures thereof at specified ratios, (b) separating extract from residual tea material (c) mixing the extract containing solution with gelatin, and (d) separating the precipitates formed under a nitrogen blanket. The resultant tea extracts are stable against precipitation, have reduced bitter and astringent flavors, low levels of polymerized or oxidized flavanols and resist browning. The extracts are especially suitable for use in beverages with added colorant where brown color is not desired.

Process for making a stable green tea extract and product

Cooking oils which have a reduced tendency to produce offensive odors when heated to frying temperatures are claimed. The oils are refined, bleached and deodorized unsaturated vegetable oils, e.g. soybean and canola and from 0.1% to 5% refined and bleached, but not deodorized sunflower seed oil. The sunflower seed oil contains terpenes which mask the fishy, painty or acrid odor and improves the oil flavor on aging.

Cooking oils

This invention relates to an efficient process for separating and recovering aroma and flavor volatiles from fruit or vegetable juices and for lowering the pectin levels in cloudy juices. The process involves removing the aroma/flavor volatiles from juice by forming a microaerosol by spraying juice at a temperature of from 45.degree. C. to 110.degree. C. through a nozzle having a diameter of about 100 microns to 600 microns at a velocity of 100 m/sec. to 250 m/sec. and into a vacuum chamber at 5 mm to 200 mm Hg and at temperatures of from 10.degree. C. to about 55.degree. C. and then treating the recovered juice fraction with a pectinase which is essentially free of esterases. The decreased pectin level increases the gustatory display of the aroma/flavor and improves the mouthfeel of the beverage. Decrease of the pectin level is achieved essentially without the formation of methanol and essentially without the hydrolysis of important aroma ester compounds. Clear juices containing a virtually pristine composition of aroma volatiles are produced after ultrafiltration of the special enzyme treated cloudy juices.

Process for making concentrated fruit juice

An improved, lightly milled roast and ground coffee having high extractability, superior brew clarity, and an aroma intensity of from about 30,000 to about 55,000 G.C. counts and a method for making the same are disclosed. Roast coffee beans are cooled to below about 65.degree. F., maintained below about 65.degree. F. as they enter the grinder, coarsely ground, and lightly milled to produce particles of coffee ranging in thickness from about 30 to about 40 mils. The coffee product has the appearance of a coarse granule with a fine powder adhering to it.
