## Abstract

A method of producing processed brown rice, containing at least the steps of: subjecting raw brown rice to heat-moisture treatment using water vapor having a temperature of from 110 to 150° C. for from 5 to 90 minutes; and subjecting the brown rice after the heat-moisture treatment to heat treatment at a temperature of from 80 to 100° C. for from 5 to 90 minutes.

## Claims

### Claim 1

A method of producing processed brown rice, comprising at least the steps of:
washing raw brown rice, and then subjecting the raw brown rice to heat-moisture treatment using water vapor having a temperature of from 110 to 150° C. for from 5 to 90 minutes; and
subjecting the brown rice after the heat-moisture treatment to heat treatment at a temperature of from 80 to 100° C. for from 5 to 90 minutes.

### Claim 2 (depends on 1)

The method of producing processed brown rice according to claim 1, wherein the mass of cycloartenol contained in 100 g of dried form of the processed brown rice is 1.4 times or more the mass of cycloartenol contained in 100 g of dried form of the raw brown rice before processing.

### Claim 3 (depends on 1)

The method of producing processed brown rice according to claim 1, wherein the mass of 24-methylenecycloartanol contained in 100 g of dried form of the processed brown rice is 1.5 times or more the mass of 24-methylenecycloartanol contained in 100 g of dried form of the raw brown rice before processing.

### Claim 4 (depends on 1)

The method of producing processed brown rice according to claim 1, wherein the total mass of cycloartenol and 24-methylenecycloartanol contained in 100 g of dried form of the processed brown rice is 1.4 times or more the total mass of cycloartenol and 24-methylenecycloartanol contained in 100 g of dried form of the raw brown rice before processing.

### Claim 5 (depends on 1)

The method of producing processed brown rice according to claim 1, comprising subjecting the brown rice after the heat treatment to a drying treatment.

### Claim 6

Processed brown rice comprising cycloartenol in an amount of 6.4 mg or more per 100 g of dried form of the processed brown rice.

### Claim 7

Processed brown rice comprising 24-methylenecycloartanol in an amount of 4.5 mg or more per 100 g of dried form of the processed brown rice.

### Claim 8

Processed brown rice comprising cycloartenol and 24-methylenecycloartanol in an amount of 11.0 mg or more in total per 100 g of dried form of the processed brown rice.

### Claim 9 (depends on 1)

The method of producing processed brown rice according to claim 1, wherein the time for the heat-moisture treatment is from 20 to 90 minutes.

### Claim 10 (depends on 1)

The method of producing processed brown rice according to claim 1, wherein the heat-moisture treatment is performed so that water content of the brown rice immediately after the heat-moisture treatment is from 20 to 70% by mass.

### Claim 11 (depends on 1)

The method of producing processed brown rice according to claim 1, wherein the time for the heat treatment is from 5 to 60 minutes.

### Claim 12 (depends on 1)

The method of producing processed brown rice according to claim 1, wherein the treatments are performed so that water content of the brown rice immediately after the heat treatment is from 25 to 60% by mass.

### Claim 13 (depends on 5)

The method of producing processed brown rice according to claim 5, wherein the drying treatment is performed under the condition of a humidity of from 30 to 70% RH.

### Claim 14 (depends on 1)

The method of producing processed brown rice according to claim 1, wherein water activity of the processed brown rice produced is 0.6 or less.

### Claim 15 (depends on 6)

The processed brown rice according to claim 6, wherein the content of cycloartenol per 100 g of the dried form of the processed brown rice is 16 mg or less.

### Claim 16 (depends on 7)

The processed brown rice according to claim 7, wherein the content of 24-methylenecycloartanol per 100 g of the dried form of the processed brown rice is 14 mg or less.

### Claim 17 (depends on 8)

The processed brown rice according to claim 8, wherein the total content of cycloartenol and 24-methylenecycloartanol per 100 g of the dried form of the processed brown rice is 30 mg or less.
