- The pouches were stored for 24 hours for discriminating the poucfies that were unsuccessfully packaged by the vacuum packer. Eight successfully vacuum-packed pouches and one non-vacuum-packed pouch were randomly chosen and stored at room temperature(20~27 ℃) to investigate the effects of vacuum packaging on the moisture content, whiteness, peroxide value, and acid value of Wiite rice with embryo.
- In this study, an automatic vacuum packer designed with functional virtual prototyping technology(Yan et al., 2003 and Erdman et al., 2001) to prolong the shelf life of white rice with embryo was manufactured and evaluated. The specific objectives of this research were to: 1.
- The effect of vacuum packaging on insect control was analyzed by counting the number of the insects suffocated in each sample in 15 days after packing rice. It was found thatall the insects in the pre-contaminated 5 samples were deadowing to lack of oxygen.
- The acid value was assayed by the method of AOCS Cd 3a-63(1973). The procedures of the method used in this study were as follows: (1) A sample was grinded using a mill, and 5 g of the powdered rice sample was measured, and then it was put into an Erlenmeyer flask;(2) 100ml diethyl ether-ethanol mixture solution(2 :1) wasadded into the flask; (3) the mixture was shaken in a shaking incubator(250C, 200 rpm) for 3 hours. The indicator of this experiment was 1% phenolphthalein.

- The vibrating conveyor module also adopted cam-follower mechanism with the eccentricity of 1 mm. An induction motor(Model 51K91A-SF90, Oriental Motor Co., Japan) was used to drive the vibrating board module. Another geared motor with a reduction rate of 1:10(Model GM JB, Mitsubishi Co.
- The developed vacuum packer was tested to pack the pouches of 2 kg(Pouch size: 25 by 30 cm), 3kg(Pouch size: 30 by 35 cm), and 5 kg(Pouch size: 30 by 45 cm).The relationship between vacuum level and vacuum time at the different pouches was investigated to improve the productivity and efficiency of the vacuum packer.
- 1 Torr accuracy was used to measure the vacuum level in a pouch.The digital vacuum gauge consisted of a 16-bit analog to digital converter, a sensor of diaphragm type, a 4-bit digital displayer, and a needle. A piece of 5 by 5 by 0.
- The procedures of the method used in this study were as follows: (1) A sample was grinded using a mill, and 5 g of the powdered rice sample was measured, and then it was put into an Erlenmeyer flask;(2) 100ml diethyl ether-ethanol mixture solution(2 :1) wasadded into the flask; (3) the mixture was shaken in a shaking incubator(250C, 200 rpm) for 3 hours. The indicator of this experiment was 1% phenolphthalein. The solution was titrated with a 0.
- Paddy(Rice variety: Dongjinbyeo) freshly harvested in September 2001 was bought from JinWon Agricultural Union, Chonnam Province. The paddy was processed into white rice embryo at the mill of Chonnam National University and was used as experimental material. The white rice with embryo had embryo adherence rate of 52% and moisture content of 16.

- The acid value is the amount of free acid present in fet as measured by the milligrams of potassium hydroxide needed to neutralize it. The acid value was assayed by the method of AOCS Cd 3a-63(1973). The procedures of the method used in this study were as follows: (1) A sample was grinded using a mill, and 5 g of the powdered rice sample was measured, and then it was put into an Erlenmeyer flask;(2) 100ml diethyl ether-ethanol mixture solution(2 :1) wasadded into the flask; (3) the mixture was shaken in a shaking incubator(250C, 200 rpm) for 3 hours.
- the amount of peroxides in the white rice with embryo by determining the milliequivalents(meq) of active oxygen per kilogram of fat. The peroxide value was determined using the method of AOCS Cd 8-53(1973). The method involves an extraction of the fat phase from the white rice with embryo using chloroform.
