DAWN OF NEW ERA
Meat Industry Problems SCIENTIFIC FREEZING "New Zealand is at the rtawn of a new era in the feeding of animals, and it can be confidently expec'eJ that a still greater proportion of the .‘feezing works’ by-products will go into feeding meals, which is its proper place in the economic structure ol the industry,” stated Mr. G. A. Lawrence, of Wellington, chairman of the New Zealand section of the Institute of Chemistry, in a paper read to the combined conference of chemists at Hamilton. Mr. Lawrence said that, in New Zealand, with the waning prices of primary products in the overseas markets, with increased foreign competition, it was essential that every endeavour should be made to utilise s- lentilic resources to improve the qu ility of all primary products, increase production, seek new avenues for the utilisation of waste materials and investigate new products. These were pre-eminently scientific problems, and any curtailment of investigational work in this sphere would be a calamity Consideration With Buyer. "Tlie primary consideration with the buyer of stock for freezing purposes—the condition and-quality of tne meat the animal will yield, blemishes on the hides or skins due to branding contact with wire and the a 11-Luo-frequent blemishes in sheep skins due t» careless shearing—must lie taken as ’hey come.” he continued. “It is pleasing to note that of lath years more atr<ntion is being given to this question, and it is to be hoped that more care w ! li be taken to eliminate as far as possible the causes of these blemishes." The relative digestibility uml nutritive properties of frozen meal as emupared with fresh meat were cmiiniented on by Mr. Lawrence. lie siul it was interesting to note that it; 19t)9 the Minister of War in Englund was asked by it private' member of the House of Commons whether lie was aware experts considered that one pound of fresh meat was worth one stone of frozen meat. In view of the results of recent work on cooking losses of frozen and fresh meat published in the “Analyst" of last year. Mr Lawrence quoted results from the work carried out in 1.89 G and 1897 by the late Dr. Samuel Rideal and published in the London journal. “Hospital,” which commented: “It is clear even from one experiment that the assertion that New Zealand meat is essentially and invariably more wasteful than English cannot be supported.” Further experiments had been carried out by Dr. Rideal on the nutritive values of frozen ami chilled meal, and in 1908 in a paper read before the International Refrigeration Congress' in Paris, he had said' “In a series of quantitative cooking trials I found that tlie food value of frozen meat was not less than (lint of fresh meat." Discrepancies in Results. "There may be good reasons for the discrepancies in the results obtained by different workers Apart from inherent differences in I lie character of the meat tlie temperature end humidity. and above nil. the rate of freezing of Various lots of moat. tuny give ilso to tlie differences obtained." Mr. Lt'w renee concluded. “On the other hand, the methods of cooking and the system adopted in returning (lie figures may partly explain tlie varying results obtained by different workers. "In view of the conflicting reports which have recently been published, it seems desirable that some competent authority should appoint a committee or board of experts to carry out the necessary experimental work and make ' a comprehensive report on *tie subjeci in order that something definite ami authoritative will be available." i
