1. Freeze-dried cod muscle and casein were subjected to various conditions of heat treat-ment. Diets containing the different products, or the unheated materials, were given to a group of four adult male rats during successive 48 h periods, and urine was collected during the second 24 h of each 48 h period. A further collection of urine was made from the rats after they had been given protein isolated from heated skim-milk powder. The content and amino acid composition of the ‘peptide’ and ‘free amino acids’ in the urines were determined.2. Heat damage to the cod-fillet protein increased the total urinary excretion of peptide-bound amino acids, from 18·6 to 48·8 µmol/rat.d. The composition of the peptide also changed, and in particular there was a marked increase in lysine, from 2·98 to 20·30 µmol %. Three amino acids - lysine, aspartic acid and glutamic acid - together comprised nearly 70 % of the total amino acid residues. There was a corresponding increase in urinary excretion of free amino acids, from 53·7 to I 14·4 µmol/rat.d. The combined losses of lysine in urinary peptide and free amino acids were 1·5 % of the total lysine ingested, as against 0·3 % for the unheated cod fillet.3. The effects of similar heat treatment of casein on the composition of the urinary peptide and free amino acids were less marked. There was no increase in total urinary peptide excretion and there was a smaller increase in the lysine content of the peptide.4. In urine of rats given protein isolated from heated skim-milk powder, the peptide hydro-lysate was rich in lysine and in furosine, which together comprised 41 mol % of the total amino acid composition. These compounds were presumably formed, together with a smaller quantity of pyridosine, from lysine-carbohydrate complex in the urine. It is probable that, as compared with free lysine, the lysine-carbohydrate complex was absorbed relatively in-efficiently from the rat intestine.5. The findings are discussed in relation to the wider question of the metabolism of the ‚unavailable peptide’ that is released in the course of digestion of heat-damaged protein.

Positive Effect

The effect of milk heat treatment (UHT vs HTST) on physicochemical properties of low-fat set-style yogurt manufactured with microbial transglutaminase was evaluated. It was also evaluated the sensory profile of microbial transglutaminase yogurt and conventional fortified yogurt using skim milk powder. The UHT treatment of milk to make yogurts treated with microbial transglutaminase showed poorer texture results (firmness, consistency, cohesiveness and index of viscosity) than the HTST treatment of milk. Yogurt texture of UHT treatment was also worse than low-fat commercial yogurts, despite of the positive effect of the microbial transglutaminase. The microbial transglutaminase addition avoided the syneresis, regardless of the type of heat treatment. A microbial transglutaminase doses at low levels (0.76 U·g-1 of milk protein) added simultaneously with the starter culture was useful for improving the textural properties and sensory characteristics of low-fat yogurt, avoiding the normal syneresis of low-fat yogurt and without increasing the protein content that happen with the addition of skim milk powder. Yogurts made with microbial transglutaminase with HTST treatment showed significantly lower whey odor than yogurt fortified with skimmed milk powder. The application of microbial transglutaminase is a useful treatment for improving textural properties of low-fat yogurt with the usual pasteurization treatment applied in the dairy industry.

Texture Parameters

The aim of this Research Communication was to investigate the changes in physicochemical, colour, apparent viscosity and texture properties in low-fat goat milk yogurts prepared with cupuassu pulp by the addition of inulin (SI), maltodextrin (SM), whey protein (SW) and skim milk powder (SP). Three batches of each cupuassu goat milk yogurt were prepared and analysed on the 1st day of storage by pH, proximate composition, colour, apparent viscosity, and texture. In comparison to yogurts from whole (W) or skimmed milk (S), all of the fat replacers improved the physicochemical properties (P < 0·05). The addition of the carbohydrates (inulin and maltodextrin) and proteins (whey protein and skim milk powder) also influenced the colour of the low-fat cupuassu goat milk yogurt (P < 0·05). All fat replacer treatments (SI, SM, SW and SP) presented a higher (P < 0·05) apparent viscosity than W and S yogurts. However, only the addition of skim milk powder increased the texture parameters (firmness and consistency) (P < 0·05). These results suggest that skim milk powder can be used to improve the texture properties of low-fat cupuassu goat milk. Furthermore, inulin, maltodextrin, and whey protein can potentially be applied in the goat dairy industry to increase the viscosity of yogurts.

Potential Use

This study investigated the potential use of fructose and stevia to improve the technological parameters of ice cream. Ice cream was made of 2 different mixtures. Low-fat ice cream mixtures (0.4% fat) were made with: sweet buttermilk, 5% fructose, 20% banana puree, and sweet buttermilk, 5% fructose, 20% pear puree. The ice cream with stevia was made with cream (13% fat), milk, skim milk powder and whey powder, cherry puree (16%) and 0.48% stevia solution (20% concentration). The ice cream with banana showed rapid melting rate and the highest acidity. On the contrary, the ice cream with pear showed lower melting rate, but caused to increase the hardness and resulted with less overall acceptability. The enrichment of the ice cream with stevia and cherry showed the same coherence of hardness and overall acceptability.

Rennet Casein

SummaryAliphatic monocarbonyls have been quantitatively estimated in casein and skim-milk powder during storage. Concurrently these products have been evaluated organoleptically. A close relationship was evident between monocarbonyl level and the flavour or age of the lactic casein. Furthermore, the greater flavour stability of rennet casein and skim-milk powder was coupled with reduced monocarbonyl content. Fractionation of monocarbonyls into classes and individual compounds has shown that the higher levels in lactic casein compared with other low-fat products can be accounted for by a high level of acetone. The absence of appreciable quantities of other odd-numbered methyl ketones suggests that either acetone is derived from a non-lipid constituent of acid casein or decarboxylation of acetoacetate is specifically catalysed at acid pH. All methyl ketones identified in these low-fat dairy products were present in subthreshold concentrations. Saturated and unsaturated aldehydes were present at similar levels in stored lactic casein, rennet casein and skim-milk powder samples irrespective of their degree of musty or stale flavour.

SummaryThe nutritional deficiencies of co-precipitate as a growth medium for a strain of Lactobacillus acidophilus have been studied. Acid production by this organism was insignificant in a medium composed of 4% low-calcium co-precipitate and 5% lactose.Additions of the amino acids phenylalanine, tyrosine, valine, cysteine and threonine as well as of nicotinic acid, manganese, magnesium and citric acid all increased acid production.When only half the milk solids of skim-milk powder was replaced by the coprecipitate, fortification with manganese only was required.
