The sucrose content of the media was 2,3 and 4%, and the process Carriedout for 3 days at 27,32 and 37 c. High yields of dry mycelium were obtained on the media containing 4% sucrose at 37 C, 3.g.3,43 g/i for R. oliogosporus and 5.08 g/l for N. sitophila. Thehighest protein content of dry mycelium were 53.9% (N. sitophilia) and 49.7% (R. oligosporus). N. sitophilia more effectively utilized sucrose and nitrogenous compounds in the media.

Juanda 5-9, Bogor b) Akademi Kimia Analis Jalan Ir. H. Juanda7, Bogor Abstract Cassava pellets were fermented for 1, 2, 3 and 4 days at room temperatureusing tempeh moulds (Rhizopus oliogosporus) and soya sauce moulds (Aspergillus oryzae). After 2 days fermentation, the protein content of products were slightly increased from 1.29% (unfermented to 1.52% (fermented by R. oliogosporus ) and to 1.58% (fermented by A. oryzae), however afer 3 days fermentation the protein content end to decrease. The ph of products drop after 2 days fermentation from 6.39 to 4.42 (R. oligosporus) and to 5.62 (A. oryzae). Organoleptic test showed that the acceptability of products were decreased after one day fermentation (taste and flavor) and after two days fermentation (colour).

Fresh and dried nutmeg were distilled by cohobation method for 2, 5, 8, 11 and 14 hrs. The optimum yield of fresh and dried nutmeg essential oil were 15.8% (14 hrs. Distillation) and 14.6% (11 hrs. Distillation), respectively. The evaporation residues of both oils were increased from ca. 0.25% (2hrs. Distillation) to ca. 0.54% (14 hrs. Distillation). Fresh nutmeg essential oil has a highest ester value (6.73 mg/g) and myristicin content (17.25%) after 8 hrs. distillation.

Balai Penelitian Makanan, Minuman dan Fitokimia, Abstract A study on the effect of preservatives (alum and bórax) and plastic packaging on the weight loss of cabbage (Brassica oleraceac) during cool storage has been done. The results showed that the shelf-life of cabbage can be prologed to one month in cool temperatura (9-10). The weight loss of cabbage during storage were 15.7% (without packaging), 5.6% (packed in perforated plastic bag) and 4.2% (packed in un-perforated plastic bag). The preservatives did not significantly have positive effects on the prevention of weight loss.

An Experiment on the Distillation and Physico-chemical Determination of Mentha (Mentha arvensis LINN.) essential Oils GASIK DARMA Balai Pengembangan Kemurgi dan Aneka Industri, Abstract Experiments on the distillation and characterization of mentha leaves essential oil have been done using three types of leaves, e.g. M. arvensis var. Piperascence ex Sukabumi and Bogor, and M. arvensis var. Javanica ex Bogor. The yield of oil were 2.0%; 1.8% and 2.7%, respectively. Menthol content of the oil were 67.6% (M. arvensis var. Piperascence ex Sukabumi ) and 53.6% (M. arvensis var. Piperascence ex Bogor). No menthol can be detected in the oil of M. arvensis var. Javanica.
