“…This was because the powder sample was already ground and mixed into one sample, and most of the protein and lipid content was inside the bean. According to Kawamura, soybean seeds have the highest protein and lipid content in the cotyledon part, containing 43% protein and 23% lipid, while the seed coat only contains 9% protein and 1% lipid (Kawamura, 1967).Therefore, the macro-and micro-components were homogenized because the sample had been ground into sample powder. However, based on the model performance, the protein model yielded better results than the lipid model.…”

Unlike standard chemical analysis methods involving time-consuming, labor-intensive, and invasive pretreatment procedures, Raman hyperspectral imaging (HSI) can rapidly and non-destructively detect components without professional supervision. Generally, the Kjeldahl methods and Soxhlet extraction are used to chemically determine the protein and lipid content of soybeans. This study is aimed at developing a high-performance model for estimating soybean protein and lipid content using a non-destructive Raman HSI. Partial least squares regression (PLSR) techniques were used to develop the model using a calibration model based on 70% spectral data, and the remaining 30% of the data were used for validation. The results indicate that the Raman HSI, combined with PLSR, resulted in a protein and lipid model Rp2 of 0.90 and 0.82 with Root Mean Squared Error Prediction (RMSEP) 1.27 and 0.79, respectively. Additionally, this study successfully used the Raman HSI approach to create a prediction image showing the distribution of the targeted components, and could predict protein and lipid based on a single seeds.

“…They have higher levels of the oligosaccharides (stachyose and raffinose) along with pectin. The pectin found in soybean meal are composed of a backbone of galacturonic acids with side chains containing rhamnose, galactose, arabinose, xylose, and fructose (Kawamura et al., 1966; Slominski, 2011). Pectin is associated with cellulose in the cell wall and become soluble in the gastro intestinal tract (GIT).…”

Poultry is an imperative domesticated livestock species that provides high quality protein and micronutrients as meat and eggs. In poultry production, feed is the single major input constituting 70–75% of total production cost. Feed mainly consists of cereal grains, those provide energy to the birds. However, these grains contain different levels of anti-nutritional factors such as non-starch polysaccharides (NSP). These NSP are indigestible by poultry birds due to the lack of vital endogenous enzymes (carbohydrases) thus increase intestinal viscosity which slower the migration and absorption of nutrients. Consequently, these NSP may also increase the chances for infection by inducing competition within gut microbiota for digestible nutrients. This affects bird's health and increases the production cost. Therefore, there is a need to find efficient and effective solutions for these problems. Carbohydrases supplementation have an important role in poultry diets with high NSP contents. Feed enzymes are being used from years to enhance growth performance and digestibility but have limited activity for selective ingredients. New generation carbohydrases with a board range of activity and stability help to degrade the complex substrates and improve growth performance of poultry. Present review summarizes the updated literature on the use of carbohydrases to improve bird's performance and intestinal health.

Summary. Automatization of a sensitive fructose assay used in the study of soya oligosides.We report the automatization of a sensitive specific assay of free fructose or that contained in various molecules. The manifold is shown in figure 1 The method is used to specifically assay saccharose and the a-galactosides (raffinose, stachyose) of various soya samples (oil meal, fermented oil meal, flour, fermented flour, soya feed) after separation by resin anion-exchange chromatography. These sugars are assayed at the same time using a total sugar evaluation method (sulfuric orcinol). Two methods for determinating fructose concentration in the column effluent are compared. One uses direct assay at the column exit at the same time as the total sugar is assayed. Oligoside concentration is obtained by comparison with the standard curves S = f(C) (S = surface, C = concentration) for each sugar. In the other method, the part of the effluent not used in total sugar assay is collected and the fructose is assayed on each carbohydratfraction. Multiplying the result by a constant measured for each sugar, oligoside concentration in the sample may be determined.Results obtained by both fructose assay methods agree and they confirm those found by assaying the total sugar (table 3). Differences between the methods are non-significant (P G 0.05). Thus, the peaks separated by the resin column contain no other carbohydrated which could interfere with the saccharose and the a-galactosides. If they did, the unseparated carbohydrates would be evaluated by difference. The results on the carbohydrate composition of soya agree with those found by other authors. Fermentation eliminates a large part of the carbohydrates from the samples. The choice of a method for evaluating saccharose and a-galactoside, using fructose, is discussed. The second is recommended because the curves S = f(C) vary in time ; this may cause errors.Introduction.
