Abstract/ Executive Summary:

The grades and classes were categorized based on the BSTI standards of rice. Moisture contents of all the samples of three districts were more or less same and below 14%. The big broken percentage was highest in Kaliziria (11.17%) followed by Chinisagar (10.83%). The small broken percentage was ranged from 3.8% to 11.52%, with an average of 7.30% which was higher than that of the upper limit of BSTI standard (7%). Other quality parameters including chalky and immature grain, damaged and dead grain admixture of other varieties, paddy foreign matters and discolored kernels were found to be at levels of almost similar to those of the BSTI standards. Kataribhog was represented grade IV, Kalizira was represented substandard grade while Chinisagor was represented grade III for all the locations. The main socio-economic problems deteriorating the quality of rice were adulteration of paddy by Faria, traditional threshing, financial crisis, lack of awareness, lack of modern drying system and proper storage facilities.

Keywords: Grading and quality, Aromatic rice varieties, Local markets

Location: Mymensingh, Sherpur and Lalmonirhat, Bangladesh

Start Date: 01-07-2003

End Date: 30-06-2004

Program Area: Quality and Nutrition

Commodity: Rice

Objectives:

To study the quality and grading of rice in modern and traditional rice mill

Methodology:

A field survey was conducted at 9 markets of 3 districts of Mymensingh, Sherpur and Lalmonirhat. The markets were selected according to popularity, situation and selling conditions. Selected 3 markets of Lalmonirhat district were Goshala Bazar, BDR Hat and Adidmari Hat. Another 3 markets of Sherpur district Noiani Bazar, Kamarchar Bazar and Nalitabarhi Bazar. The markets of Mymensingh district are Baro Bazar, Natun Bazar, Churkhai Bazar. An interview schedule was prepared according to the need of the objectives of the study. In order to collect information interview schedule was carefully prepared. The schedule was pre-tested before administration. The final schedule was prepared after necessary corrections and modifications. To gather information relevant to rice quality, grading, storage, adulteration and marketing personal contact was made with the miller, Faria, wholesaler and retailer. Samples were collected after selecting the most popular and commonly sold varieties of milled rice by taking interview with the traders and with the wholesalers. Data were collected from 3(three) popular aromatic varieties namely Kalizira, Kataribhog and Chinisagor. For each variety, 200 gm of rice was taken in polythene bag randomly by sample auger. Problems associated with the production of good quality rice were recorded during survey. Collected samples were analyzed in the laboratory using standard methodology. A Kett moisture meter (made in Japan) was used to measure the moisture content of rice samples.

Achievement/Findings:

The moisture contents of all the collected rice samples of Kataribhog, Kalizira and Chinisagor from different markets were found to be less than that of maximum limit of BSTI standard (14%), therefore, rice varieties sold in local markets satisfied the BSTI standard for moisture content. The big broken percentage of Kataribhog, Kalizira and Chinisagor were 11.17%, 4.58%, and 10.83%. The small broken percentage of Kataribhog, Kalizira and Chinisagor 10.35%, 12.38 and 4.90, respectively. The small broken percentage indicated a higher percentage than that of BSTI standards. So, the millers have to take effective care to produce less broken. The maximum percentage of admixture of other varieties was 5.63% which was less than BSTI maximum limit (15%). So, maximum limit of admixture of other varieties should be changed from 15% to 6%. Other impurities such as yellow, dead and damaged kernels, chalky and immature kernels, and discolored kernels were also within the limit of BSTI standards. Percentage of small broken of each of the collected samples of the rice varieties was more than that of BSTI standards excepting fine varieties. Aromatic varieties such as Kataribhog represented grade IV, Kalizira represented substandard grade while Chinisagor represented grade III for all the locations. The socio-economic problems as were identified to the production of good quality rice are adulteration of paddy by Faria, traditional threshing, financial crisis, lack of awareness, lack of modern drying system and proper storage facilities.
