Nata de coco rich in high dietary cellulose microfiber of low calories and thus suitable to be promoted as healthy drink is derived from bacterial fermentation of coconut water (an agricultural by-product). In this study the optimal amount of nata de coco to be added to mao juice was investigated. Nata de coco was produced by using Acetobacter xylinum TISTR 86 cultured at 30oC for 15 days in a plastic box containing culture medium which was composed of 92.5% coconut juice 0.5% ammonium sulfate 5.0% sucrose and 2.0% vinegar. Hedonic scale (1-9 point) sensory evaluation was used to select the optimal ratio of nata de coco from the 3 ratios of 5 10 and 15% to be added to mao juice. Based on taste and overall liking the most favorable mixture is to add nata de coco of 10% to mao juice. Finally the chemical physical and microorganism properties of mao juice with nata de coco in a 180 ml clear-glass bottle were measured after it was stored at room temperature for 1 month. This mixture product was found to beneficially contain fiber two times the amount of that of sole mao juice. The result suggests that these variable parameters of mixture product were accepted base on the Thai Community Product Standard (486/2547).

The objective of cereal bar (Khao Mao Mee) development project is developing project is developing formula and production process.- to increase nutritive value and convenience in carrying comfortably. according to study of 3 basic formulas by randomized complete block design (RCBD)the results showed that the overall liking of like moderately (7.67)the study of hot air dried carrot at 70c by randomized complete block design (RCBD)...

The aims of this research was to study the general situation in aspects of productivity and marketing of Mao fruits in Sakonnakon. Cost and return marketing channel and marketing margin of Mao fruits were investigated during 2007–2008 using purposive sampling and descriptive analysis. Twelve gardeners who own the average 7 years Mao orchards in Pupan Kudbak Sawangdandin Nikomnam-oon and Warichapoom District in Sakornnakon province informed that the productivity of Mao fruits was 750 Kg/annum in average. The average price of Mao fruits was 25 Baht/Kg. The net returns of Mao fruits was 7216.89 Baht/rai/annum. Marketing channel of Mao fruits were fresh fruits eaten and used as raw material in fruit juice processing plants. The whole commodity of Mao in orchard was traded and distributed by middleman. Earnest money deposit was required. The price of Mao fruits was 25 -35 Baht/Kg for the processing plants. The profit was 9104.50 Baht/ton or 36.41% of net income.

In this study the mao berry marc which was divided into 5 varieties including Fapratan Phusung Phupanthong Yaykhamta and mixed variety were dried in tray dryer at low temperature (50?C) and high temperature (60?C) for 72 hr. All samples were investigated their properties including yield color water activity pH tannin total phenolic total anthocyanin antioxidant activity in term of %DPPH activity total microorganism and yeast & mold content. It was found that the yield color in term of ?h aw tannin and anthocyanin content of low temperature drying sample showed the highest value. However the total microorganism and yeast & mold content of high temperature drying samples were not present in all samples which less than those recommended in the Thai Community Product Standard (dried fruits: 136/2003). Eight trained-panelists were used for Hedonic scale (1-9 point) sensory evaluation including clarity color odor taste and overall linking of high temperature drying samples were similar in five varieties (P>0.05).
