Abstract

The disadvantage of using sun Drying are its dependance on weather, contamination of insects, unequality of the product dryness and quality, high labour and operational cost, and limitation of drying area. Mechanical dryer would lessen the above problems. This research is aimed at the making and testing of prototype of box type mechanical fish dryer of 200 kg capacity. The quality of dried product is relatively equal to commercial products. The drying condition are as follows: Temperature 40 degree-50 degree celcius, RH 40 0-50 0 %, drying air velocity 90-120 m/min. on the plenum, and temperature around the fish 29 0-36 0 C.

Abstract

The effect of sodium benzoate and citric acid to the quality of jack fruit juice during storage has been studied. The concentration of sodium benzoate used were; 500 and 1000 ppm, while citric acid were 0;0.1 and 0.2 percent. The result showed that sodium benzoate significantly affect the total acid, pH and total microbial count. The higher the sodium benzoate concentration, the lower the total acid will be, while the pH will increase and total microbial count decrease. The addition of citric acid resulted in the decrease of total acid and vitamin C, while the PH increase. Vitamin C content, pH, total soluble solid and viscosity decreased during storage and total microbial count increase. Organoleptic test showed that the addition of 0.1 percent citric acid is acceptable.

Abstract

A study on the low-temperature preservation of paddy-straw mushroom (Volvariella volvaceace) has been carried out. Stages of treatments include trimming, washing, blanching (0, 2, 4 and 6 min), cooling (cool water spraying for 30 min), packaging (without packaging, packed in polyethylene and vacuum packed films), and storage at cool temperature. Observation were done on moisture content. PH, Total acid, suluble solid, activity of catalase and peroxidase, and organoleptic  test. The Results showed that paddy-straw mushroom can be preserved for two weeks at 7 degree-9 degree celcius in vacuum packaging (4-6 min blanching).

Abstract

The essential oils from Indonesian cinnamon leaves (Cinnamomun burmanii, Cinnamomun zeylanicum, and Cinnamomun cassia) was extracted using cohobation method. The distillation process was carried out for 3 hrs. The oil was trapped at different temperature i.e 25 degree, 70 degree and 85 degree celcius. The result showed that 70 degree celcius was the optimum temperature. The yield of oil were 0.57;1.62 and 0.31% respectively. Major components of the oils were cinnamic aldehyde and small amount of eugenol (C.burmanii), eugenol and one unidentified component (C.zeylanicum) and cinnamic aldehyde and o-metoxycinnamaldehyde (C.cassia)
