    Notizen: A laboratory version of orgoro; a low alcohol plantain beverage was found to possess a better odour, taste and colour after 7 days of fermentation compared with a native brew. The pH of the native brew decreased from 3.90 to 1.93 after 21 days of fermentation while the filterable acidity increased from 0.100 to 0.157%. The laboratory brew showed a decrease of pH from 4.60 to 2.72 and an increase in filterable acidity from 0.250 to 0.485%. Both brews had alcohol contents of 0.109 and 0.197% (v/v) respectively after this period. The total sugars content, soluble protein and total nitrogen contents of the native brew were 2.0 mg/ml, 1.3 mg/ml and 2.05 mg/ml respectively while values for the laboratory brew were 5.0 mg/ml, 2.2 mg/ml and 4.0 mg/ml respectively.

    Notizen: Millet (Pennisetum typhoideum) its malt and wort were evaluated to ascertain the suitability of the grain for beer production. Thousand grain weight was 8.03 g while foreign material and broken cernels represented 3.23%. Germination energy, germination capacity and moisture content of the grain were 75.67, 92.33 and 10.43%, respectively, while the carbohydrate, total nitrogen and protein contents were 53.88, 1.34 and 8.40%, respectively. Millet malt had a moisture content of 5.03% while its carbohydrate, total nitrogen, protein content and malting loss were 48.47, 1.87, 11.7 and 8.3%. pH and specific gravity of the worth were 5.70 and 1.5927, respectively; its protein content was negligible while % titratable acidity was 1.35. The low nitrogen and protein contents of the grain as well as the low malting loss make millet an attractive alternative cereal for beer production in Nigeria.

    Notizen: A controlled brew of pito was produced and compared with a native brew. The former contained a higher alcohol content than the latter brew and was brighter in colour (13 as against 18.5 EBC units) thus making it more attractive. Of various heat and chemical preservative treatments used to prolong the shelf life of both products, pasteurization at 75°C for 30 min. and treatment with sorbic acid at a concentration of 5% were best able to arrest microbial proliferation in the bottled products during a 4 week storage period.
