B arley protein research es. Prediction of extract.

II . Effect of variety on relation betw een nitrogen content and extract. L . 11. Bi s h o p and F. E. Da y

( J . Inst. Brew., 1933, 39, 545—551).—The extract

equation derived previously (B., 1930, 1087) is modified to E — A — 10 • 5N + 0 • 20G, where A is a const, depend­

ing on the variety of barley. Average vals. of A are 108 and 101-5 for English and Californian barleys, respectively. Differences between prediction and analy­

sis arc due to sampling errors, variations in malting conditions, and an unknown factor in the barley.

D evelopm ent of a m y la se during germ ination of barley. H. Lu e r s and W. Ru m m l e r (Wocli. Brau., 1933, 50, 297—300).—After 3 days’ germination the ratio of liquefying power (I) to the dextrinification const, (cf. Sabalitsclika, A., 1929, 721) is approx. const. A close relation thus exists between the dextrinogen (a-) amylase and (I). The increase in saccharifying power caused by digestion of the barley with papain (cf.

Weichherz and Asmus, A., 1931, 1089) is due to the liberation of protein-bound amylase by the proteasc of

the papain. R . H. II.

The cover of the vessel is annular, and a disc of the dough under examination is placed over the opening ; as the disc deforms it causes the manometer curve to vary in a manner which indicates the mechanical characteristics of the dough. The results are expressed in terms of the tenacity, elasticity, and extensibility of the specimen. The theory and method of operation of the apparatus are described in detail, and typical results are reproduced and discussed. H. F. G.

E. MamJjEi and R. Cu l t r e r a (Ind. ital. Conserve aliment., 1 9 3 3 , 8 , 12 5 ; Chem. Zentr., 1 9 3 3 , i, 2 4 7 8 ) .Fresh milk (I) contains vitamins -A , -B, -C, and -D.

Curds (II) and whey (III) contain the same vitamins in concn. corresponding w ith their proportion in (I). In cheese (IV) the content increases with progressive ripening. Autoclaving (IV) a t 1 4 0 ° for 3 hr. destroys v itam in -/); vitam in-5 is destroyed by heating (II), (III), or (IV) a t 5 25 4 ° . Vitamin-/? is again formed in (IV) on ripening.

D ry residue of m ilk determ ined indirectly by Fleisch m an n ’s form ula. M. Cdji (Boll. Chim.- Farm., 1 9 3 3 ,72, 6 8 56 8 7 ) .—The dry residue is given by

2 - 6 6 5 ( 1 0 0 < i1 0 0 ) + 0 - 2 ^ , where d is sp. gr. and g

Fleischmann’s relation between d and fat (I) and dry substance contents is confirmed. W ith increase in (I) the solids-not-fat (II) increase. The different quantities of milk of particular cows do not markedly affect the d of the mixture, but affect its (I). The ash of moming is > th a t of evening milk. The ratio (I) : (II) is characteristic of the breed of cattle. A. A. E.

W hy does a tallow y flavour develop in straw ­ berry ice cream ? 0 . E. Ross (Ico Cream Trade J., 1933, 29, No. 7, 23—25).—F a t oxidation is probably the cause of the flavour d efect: oxidising enzymes, Fe, and strawberries do not appear to be concerned. Ice cream (I) made with condensed milk developed the oll-flavour more readily than did (I) made with skim- milk powder, possibly owing to the higher Cu content of the condensed milk. Ch. Abs.

Butter from sh e e p ’s and g o a ts’ m ilk. T. G.

St a t h o p o u l o (J. Pharm. Chim., 1933, [viii], 1 8 , 287—

289).—The physical consts. of (Grecian) butters from sheep and goats differ markedly from those of cows’

butter, particularly in regard to the Reichert Meissl (R.-M.) val., which is low. Figures for <Zl0l), butyro refractive index, and the acid, sap., R.-M., Polenske, Hclmer, and I vals. are tabulated. H . D.

1932, 795, 1131).—Chemical and physical data arc given for 13 commercial specimens of casein (I) and for 5 specimens made by different methods from the same sample of milk. No correlation exists between the method of manufacture and either the paper-coating quality or tendency to foam (F). Neither F nor adhesive strength (A) is related to the % fat in (I).

“ Self-sour ” lactic-(I) gives smoother-surfaced coatings but has lower A than HC1-(I). The % ash is an index of A, but the % CaO is an index only when one type of (I) is being considered. Neither F nor the viscosity (r;) of clay-casein slips varies as the r, of solutions of (I).

quent thaw ing of fruits and vegetables. M. A.

Jo s l y n and G. L. Ma r s h (Fruit Prod. J., 1933, 12, 330—332).—Treatment with S 0 2 necessary to preserve the colour of certain apples, apricots, and peaches after freezing and thawing has been studied. Peas, beans,

and asparagus blanched in steam for 1 min. retained their flavour during storage for 1 year. Changes in flavour due to changes other than oxidation occur in prolonged storage. The development of PhCHO flavour in peaches and cherries and off-flavours due to anaerobic respiration were especially noticeable.

III. Exposure to an atm . containing 20% 0 2 and >

10% C 02 induced changes in the rate of 0 2 intake by certain fruits and vegetables. The effect varied both in direction and intensity with the nature of the material and the [C 02].

IV. A decrease in the of the sap of various plant tissues resulted from treatm ent with C 02 in the presence of 0 2. Subsequent storage in air caused a return to normal conditions. The rates of change and of recovery varied with the nature of the tissue. The natural p n gradient in potato tubers (increasing from surface to centre) is reversed by C 02 treatm ent in the presence of 0 2. In the absence of 0 2 the treatm ent increases the

acidity of the sap. A. G. P.

D eterm ination of chlorogenic acid in coffee.

H. Ju r a n y (Z. anal. Chem., 1933, 9 4 , 225—232).—The coffee is extracted with 80% EtOH, and fats and waxes are removed from the extract by addition of H 20 and solid paraffin. Pb chlorogenate is pptd. by adding Pb(OAc)2, filtered off, and decomposed in suspension by H 2S. The free chlorogonic acid so formed is determined (1) with 0 • 1 Af-NaOH (bromothymol-blue), (2) polar- imetrically. Raw coffee contains 7 • 6—9 • 1 % and roasted coffee 2— 4% of the acid. H. J . E.

P acking of ground coffee. J. W. Bl a c k (Food, 1933, 3, 39—40).—Carrasco’s remarks ( B ., 1933, 844) are criticised. Some results of the quantity and composition of gases given off by ground coffee are given, and a method of packing coffee in its own gas is

Univ. Sofia Agric. Fak., 1931—32, 10 , 225—252 ; Bied.

Zentr., 1933, A , 3, 417).—Daily administration to sheep of 20 g. CaC03 in conjunction with an oats-hay ration had no effect on digestibility. The Ca balance was changed from negative to strongly positive, and the P balance in the reverse direction. The N balance remained positive although there was increased elimin­

Influence of acetic, lactic, and butyric acids on resorption of nutrients and on the calcium and phosphorus m etab olism of rum inants. W . Li e b- s c h e r (Z. Tierzucht., 1931, B , 23, 95—121 ; Bied.

Zentr., 1933, A , 3, 416—417).—Addition to sheep’s rations of small amounts of AcOH (I), lactic acid (II), or

P rC 02H (III) did not affect the digestibility of the total org. m atter, N-free extractives, or crude fibre, but im­

proved th a t of crude fa t [except in the case of (III)] and decreased th a t of crude protein. Administration of a mix­

ture (approx. 1 : 2) of (I) and (II) practically eliminated the ill effects of the individual acids. Small doses of (II) (0 • 7 g.) raised the N, Ca, and P balances ; larger amounts had no further effect. Highest N retention occurred w ith additions of (III). (I) reduced the N balance.

All acids favourably affected Ca metabolism. P m eta­

bolism was improved by small amounts of all acids.

Larger proportions of (I) had an unfavourable action, which was corrected by admixture with (II). A. G. P.
