Abstract: A natural grapefruit juice concentrate prepared from natural grapefruit ingredients is disclosed. The concentrate has at least 35% solids including pulp, non-volatile compounds, pectin and volatile compounds. The concentrate has at least 65% of the aroma and flavor volatile compounds of the natural juice. The concentrate is prepared by separating natural grapefruit juice into a particulate solids portion (such as pectin or pulp) and a serum portion. The serum portion, which comprises 7 to 20% solids and from 80 to 93% water, is concentrated by removing essentially pure water. The concentration step can be accomplished by freeze concentration or by sublimation concentration. When sublimation concentration is used, the particulate solids do not have to be separated from the serum. Substantially 100% of the non-volatile solids are retained, and the concentrate is substantially free of oxidative degradation products.

Abstract: A natural orange juice concentrate prepared from natural orange compounds is disclosed. The orange juice concentrate has at least 35% solids including pulp, non-volatile compounds, pectin and volatile compounds. This orange juice concentrate has at least 65% of the aroma and flavor volatile compounds of the natural juice. The aroma and flavor volatile compounds comprise a low boiling fraction and a higher boiling fraction in a ratio of at least 4:1. The ethyl butyrate level is at least 0.1% of the total volatile compounds, the proportion of ethyl butyrate to limonene being in the range of 0.0015:1 to about 0.6:1.The orange juice concentrate is prepared by separating natural orange juice into a pulp portion and a serum portion. The serum portion which comprises 7% to 20% solids and from 80% to 93% water is concentrated by removing essentially pure water. The concentration step can be accomplished by freeze concentration or by sublimation concentration.
