摘要:

AbstractThe lead content of 55 Australian wines was determined, the values ranging from 0.04 p.p.m. to 0.86 p.p.m. with a mean of 0.23 p.p.m. The wines comprised both export and home consumption samples and represented white and red, sweet and dry, and unfortified and fortified types.The results are discussed in relation to the legal limit of one part per million of lead in wine recently introduced by the British Ministry of Food.The literature relating to the lead content of wines is reviewed.

摘要:

AbstractChemical analyses of fodder‐beet harvested at approximately fortnightly intervals from a (single) crop left in the ground all the winter showed no marked changes with the passage of time. The quality and palatability of the roots were almost unchanged. The results indicate the possibility of reducing costs by leaving fodder‐beet in the ground over winter and folding pigs on

摘要:

AbstractA method suitable for investigating the penetration of herbicide spray into ground‐crop foliage is presented. The sampling variation is likely to be rather high, but the method can at least differentiate between broadly different treatments. Under the conditions of the trial, a high‐volume application resulted in a greater retention of spray at the level of the weeds than did a low‐volume applic

摘要:

AbstractA number of estimations have been made of the amount and composition of the expressible fluid obtained from gutted cod iced for various periods. The amount of expressible fluid increased rapidly as the fish passed out ofrigor mortisand then only slowly for a period, followed by a further fairly rapid increase after 168 hours on ice. It is suggested that the values‐obtained are associated with the physical changes in texture that occur during the gradual resolution ofrigor mortisand with subsequent slight changes in texture and in the colloidal proteins of the protoplasm. The amount of expressible fluid obtained does not appear to be related to the size of the fillet

摘要:

AbstractA graded extraction procedure has been applied to the polysaccharides present in the kernels of oats,Avena sativaL. Analyses of the sugar, protein and ash content of the fractions obtained are reported. A method for the purification of the starch present in the kernels is given. Oxidation of the unfractionated starch with potassium metaperiodate showed that the ratio of terminal to non‐terminal glucose units was 1 to 27.4. Differential potentiometric iodine titrations indicatied the presence of 26.0% of amylose in the starch, and hence the average length of unit‐chain in the amylopectin component was calculated to be 20.3 glucose units. Examination of the impure intermediate starch products showed that the protein impurity interfered considerably with the interaction of the starch with potassium metaperiod

摘要:

AbstractIn this paper experiments on ethylene dibromide fumigation of different cereal species are described in which the influence of various fumigation conditions on the content of bromine is studied. Two bromine forms were found to be present in fumigated grain: a volatile bromide (unchanged ethylene dibromide), and a non‐volatile, water‐soluble bromide. Differences in sorption of ethylene dibromide by various cereals seemed to result from differences in seed structures.By airing of fumigated grain free ethylene dibromide is removed gradually, but the content of bound bromine is not markedly changed. Under usual conditions of fumigation of whole grain in silos, the volatile bromide disappears after airing for 6‐7

摘要:

AbstractFeeding experiments with laying hens showed that ethylene dibromidesorbed by grain is injurious to egg production. When grain containing 200 p.p.m. of free EDBThe abbreviation EDB is used throughout this paper for ethylene dibromide.was fed to hens for 56 days, or that containing 300 p.p.m. for 46 days, the hens ceased laying completely. Feeding of grain containing 10 p.p.m. caused a slight diminution of egg size after 12 weeks. The residual bromide has no influence on laying and therefore fumigated grain that has been sufficiently aired can be safely used for poultry feeding.

摘要:

AbstractPreliminary experiments designed to ascertain whether extracts of seaweed afford suitable media for the propagation of yeasts are described. Various extracts from seaweeds as well as carbon‐rich compounds isolated from seaweeds have been used as media or as media supplements for the cultivation of 46 strains of yeast, representing a wide range of yeast genera. Further, the effects of variations in. the environmental conditions upon such cultures have been studied. In general, extracts fromLaminaria cloustoni(frond) were found to afford the most suitable media, andCandida krusei, Candida solani, Nadsonia fulvescens, Pichia membranaefaciensandOospora lactiswere the most prolific yeasts. Aeration of the cultures tended to increase the yield. No appreciable increase in yield was obtained when yeasts were cultivated in media prepared from seaweed treated with 0.1 and 1.0 N‐hydrochloric a
