Chemical Composition and Nutritional Evaluation of the Lupine Seeds (Lupinus albus L.) from Low-Alkaloid Varieties

Abstract

The aim of this paper is to analyse the chemical compositional and nutritional profiles of a two number of white lupine cultivars (Lupinus albus, cultivars Amiga and Energy) suited to the pedoclimatic conditions in Romania, collected in the year 2015. No significant differences were observed among lupine cultivars in their dry matter (DM), crude ash or alkaloid contents. The highest protein content (36.4�1.1% of DM) and crude fat (10.1�1.2% of DM) was found in seeds from lupines belonging to cv. Amiga, while the highest crude fibre content (15.2�1.7% of DM) was found in cv. Energy. Both varieties examined were characterised by a shortage of methionine and lysine, but lysine deficiency was higher in cv. Energy. Amiga cultivar was found to be a nutritionally more valuable crop than cv. Energy by the standards of nutrition for mature human and animals (chicken broilers and growing pigs). Amiga lupine was characterised by a higher essential amino acid index (EAAI) as well as chemical score (CS) of lysine, and the high nutritional index (NI) and biological value (BV) of protein as compared to cv. Energy. The white lupine seeds examined can serve as a source of good quality food protein for adult humans, meet the requirement for exogenous amino acids (EAA) and Lys in chicken broilers and to a lesser degree in the case of growing pigs, according to the standards of nutrition used. Fatty acid (FA) composition showed that oleic acid (C18:1 n-9) was the major fatty acid, followed by linoleic (C18:2 n-6) and linolenic (C18:3 n-3) acids. Apart from the highest level of polyunsaturated fatty acids (PUFA) the seed oil of Amiga cultivar showed and the largest content of linolenic acid (n-3) and the most favourable report n-3/n-6 FA.

Study of Fatty Acids Profile and Oxidative Stability of Egg Yolk from Hens Fed a Diet Containing White Lupine Seeds Meal

“…The decrease LA:ALA ratio in diets containing WL resulted from the fact that white lupine seed meal were a rich source of ALA (C18:3 n-3) and a poor source of LA (C18:2 n-6). Our results are consistent with the findings of Strakova et al [30] and Mierlita et al [7] who demonstrated that white lupine oil is characterized by the high concentrations of n-3 PUFA levels. White lupine seeds meal showed a substantial content of tocopherols (table 2) which can ensure high oxidative stability to fat from egg yolk.…”

“…Amiga) were obtained under the pedo-climatic conditions of Transylvania (Romania) and were also analyzed for CP (33.80%), crude fat content (9.84%, as-is basis) and DM (92.18%) in the laboratory. This cultivar is characterized by a low alkaloid content of seeds [7]. The white lupine seed meal was used as a substitute for soybean meal in the diets of laying hens.…”

“…Carrier gas was helium at 1.0 mL/min ratio. The temperature of injection port was 230 o C with the split ratio of 1:80, temperature program was 80 o C/5 min, 200 o C/30 min, and 230 o C/15 min [7]. The FAME were identified using external standards (Supelco 37 Component FAME mix; Supelco Bellefonte, PA, USA), and the FA contents were calculated from the peak area of the corresponding fatty acid in relation to the total area of all peaks.…”

“…Apart from low levels of anti-nutritional factors, modern lupine varieties are also characterized by higher concentrations of high-quality protein [7], and a higher yield [8]. The seeds of white lupine can be a valuable ingredient of laying hen diets due and to high concentrations of unsaturated fatty acids (UFAs) [2,7] which can enrich the egg yolk with essential FAs.…”

Contributions on the Sensorial, Physico-Chemical and Nutritional Characterization of Meat in Flemish Giant Rabbit Breed

“…These nutritional properties satisfy the desire of modern consumers to have a healthy lifestyle [1-3, 6-9, 12-66]. Rabbit meat fits perfectly to these requirements; the main feature in its assessment is the increased content of monounsaturated and polyunsaturated fatty acids [63][64][65] that are directly involved in human health [68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85].…”
