Detoxication of tung meal

Claim 2

The process of claim 1 wherein step (a) is conducted in conditions substantially resistant to fermentation and continued for at least 1 hour.

Claim 3

in process step (c) the dewatered swollen tung meal is treated with from about one to about 10 times its weight of a lower alcohol at a temperature of about 0* C. to about 100* C. for a period of at least one-half hour.

Claim 4

in process step (b) the sifted tung meal is soaked in water at a temperature of about 0* C. to 100* C. for a period of from about 1 to about 96 hours; and

Claim 5

in process step (b) the sifted tung meal is soaked in three times its weight of water at a temperature of about 80* C. for about 12 hours while being agitated;

Claim 6

in process step (d) the toxic matter is extracted by contact with about three times its weight of an alcohol selected from a group consisting of methanol, ethanol, propanol, butanol, and pentanol at a temperature of about 60* C. for about an hour while being agitated, and wherein the tung meal is dried following process step (e).

Claim 7

in process step (d) the water-soaked swollen dewatered tung meal is treated with about one to 10 times its weight of the alcohol at a temperature of about 0* C. to about 100* C. for a period of about 1/2 to 24 hours.

Claim 8

The process of claim 1 wherein the organic solvent is selected from the group consisting of saturated alcohols containing from one to nine carbon atoms.

Claim 9

The process of claim 3 wherein step (a) is conducted in a substantially acid condition to provide substantial resistance to fermentation.

Claim 10

The process of claim 1 wherein the organic solvent is ethanol.

Claim 11

The process of claim 1 wherein the acid condition is a pH value of 1 to 3.

Claim 12

The process of claim 1 wherein:

Claim 13

The process of claim 1 wherein:

Claim 14

The process of claim 8 wherein step (c) is repeated from one to 19 times and the alcoholic solution of toxic matter is removed between treatments with alcohol.

Claim 15

The process of claim 9 wherein the alcohol is ethanol.

Claim 16

The process of claim 10 wherein the step (c) is repeated three additional times.

Claim 17

A sequential process for preparing a foodstuff from tung meal containing particulate tung hull, which comprises: a. removing a portion of the hull mAterial from the tung meal; b. soaking the tung meal in from about one to about 10 times its weight of water at a pH from about 0.1 to 7.0, to macerate, and swell the meal and to dissolve water-soluble toxic matter; c. separating the water and dissolved toxic matter from the swollen tung meal; d. extracting toxic matter from the dewatered swollen tung meal with a lower aliphatic alcohol; and e. separating the alcohol and toxic matter from the tung meal.

Claim 18

The process of claim 12 wherein the sequence (d) through (e) is repeated two to 20 times.

Claim 19

The process of claim 12 wherein the tung meal is dried after step (e).

Claim 20

The process of claim 12 wherein:

Claim 21

The process of claim 15 wherein:

Claim 22

The process of claim 16 wherein the alcohol is ethanol.

Claim 23

The process of claim 16 wherein the sequence of process steps (d) thru (e) is repeated three additional times prior to the drying step.

Claim 24

The process of claim 18 wherein the alcohol is ethanol.
