Abstract A one-day ration can be supplied to a soldier in the form of one ration pack for 24 hours or three packs of meal ready-to-eat, which equals one 24-hour ration. Based on the physical activity level and consequently energy requirements, there are two categories of military operations: a) normal operations, comparable to urban police work or firefighting, and b) combat operations which represent missions involving light-infantry. The aim of this study was: a) to analyse the EU market on the subject of a main course (MC) product in flexible packaging (n = 184), in the context of military use, and b) to develop thermostabilised MC aligning with modern health and nutrition recommendations for military use, i.e. protein, carbohydrate, fat, total energy intake, and essential amino acid composition. The greatest amount of ready-to-eat meals with shelf-life over one year are produced in the United Kingdom (n = 48) and most of the MC meals are preserved using freeze-drying (n = 135). While 90% of analysed products meet fat criteria for a physically active consumer (i.e. soldier), 39% meet carbohydrate criteria, 21% meet energy intake criteria, only 1% of the products are able to fulfill protein requirements. In this study, nine MC meals with shelf-life of three years were developed, which provide the necessary protein amount for a highly physically active consumer and cover its daily essential amino acid requirements.

This article reports the amino acid composition of the Nigerian local cheese called ‘wara’. ‘Wara’ is made by boiling cow milk with some added coagulant to cuddle the milk protein resulting in coagulated milk protein and whey. ‘Wara’ used to be an excellent source of nutrients such as proteins, fats, minerals and vitamins. Samples were purchased in Ado-Ekiti, Nigeria. Amino acid values were high (g/100g crude protein) in Leu, Asp, Glu, Pro, Phe, Arg with total value of 97.7. The quality parameters of the amino acids were: TEAA (42.6g/100g and 43.6%) whereas TNEAA (55.1g/100g and 56.4%); TArAA (12.8g/100g and 13.1%); TBAA (14.2g/100g and 14.5%); TSAA (3.10g/100g and 3.17%); %Cys in TSAA (51.4); Leu/Ile ratio (1.74); P-PER1 (2.65); P-PER2 (2.48); P-PER3 (2.41); EAAI1 (soybean standard) (1.29) and EAAI2 (egg standard) (99.9); BV (97.2) and Lys/Trp ratio (3.62). The statistical analysis of TEAA/TNEAA at r=0.01 was not significantly different. On the amino acid scores, Met was limiting (0.459) at egg comparison, Lys was limiting at both FAO/WHO [24] and preschool EAA requirements with respective values of 0.966 and 0.97. Estimates of essential amino acid requirements at ages 10-12 years (mg/kg/day) showed the ‘wara’ sample to be better than the standard by 3.72-330% with Lys (3.72%) being least better and Trp (330%) being most. The results showed that ‘wara’ is protein-condensed which can be eaten as raw cheese, flavoured snack, sandwich filling or fried cake.

Deficiencies in protein and energy intakes are partly responsible for age-related sarcopenia. We investigated the effects of supplements matched in essential amino acid (EAA) content (7.5 g) on energy intake and appetite. Ten women aged 69.2 ± 2.7 years completed 3 trials in a randomised, crossover design. Composite appetite scores, peptide-YY (PYY), and insulin responses to a 200-mL whey protein (WP) isolate (275 kJ), a 50-mL EAA gel (GEL, 478 kJ), or nothing as the control (CON) condition were investigated over 1 h, followed by an ad libitum breakfast. Energy intake at breakfast (CON, 1957 ± 713; WP, 1413 ± 623; GEL, 1963 ± 611 kJ) was higher in CON and GEL than in WP (both P = 0.006). After accounting for supplement energy content, energy intake in GEL was higher than in CON (P = 0.0006) and WP (P = 0.0008). Time-averaged area under the curve for composite appetite scores (CON, 74 ± 20; WP, 50 ± 22; GEL, 60 ± 16 mm) was higher in CON than WP (P = 0.015). Time-averaged area under the curve for PYY (CON, 87 ± 13; WP, 119 ± 27; GEL, 97 ± 22 pg·mL−1) was higher in WP than CON (P = 0.009) and GEL (P = 0.012). In conclusion, supplementation with WP facilitated an increase in protein intake, whereas supplementation with GEL increases in both energy and protein intakes, when consumed before an ad libitum breakfast. Such findings highlight potential gel-based EAA supplementation intake for addressing age-related sarcopenia.

ABSTRACTWhole-body amino acid composition was determined in six male and six female 53-day-old New Zealand White rabbits. There were no significant sex differences in whole-body amino acid compositition except for arginine and glycine where whole-body concentrations (g/16 g N) were significantly lower in the females (P < 0·05). Overall mean whole-body essential amino acid levels (relative to lysine = 100 units) were methionine = 20; cystine = 41; histidine = 50; phenylalanine = 65; tyrosine = 50; threonine = 64; leucine = 112; isoleucine = 51; valine = 62; arginine = 109. The lysine concentration of rabbit whole-body tissue was 6·12 g/16 g N. There was close agreement between rabbit whole-body amino acid composition and corresponding published values for the rat and pig, although the rabbit whole-body cystine was high and methionine concentration low compared with the rat or pig. The rabbit whole-body amino acid pattern can be regarded as approximating an ideal balance of dietary amino acids and as such indicates discrepancies in current recommendations on the essential amino acid requirements for growth in the meat rabbit.
