“…Furthermore, during the storage of RSM, modifications of the protein digestibility and availability of amino acids can also occur. Research conducted by Bojanowska (2017) reported a statistically significant decrease in the content of most non-essential amino acids and methionine. Another factor affecting protein digestibility is its interaction with other compounds present in RSM, for example dietary fibre, phytic acid, and tannins.…”

Rapeseed is an important oil crop worldwide, with an annual production of more than 70 million tons. Rapeseed meal (RSM) is a by-product of rapeseed oil production and is second after soybean meal (SBM) in the world production of protein meal. Rapeseed meal derived from black-seeded winter oilseed rape (Brassica napus L.) usually contains between 35 and 40% of crude protein (CP), which is considered to be one of the more valuable plant proteins. It has a good balance of essential amino acids and a very high protein efficiency ratio (PER=3.29). However, full utilisation of this protein is difficult due to presence of the non-protein components of the seed which are associated with it. These are called antinutritional factors and they limit the utilisation of RSM in monogastric animal nutrition. The main antinutritional factors in RSM are dietary fibre, glucosinolates, phytic acid, and phenolic compounds (sinapine, tannins). For many years, research has been conducted in many centers around the world to improve the nutritional value of RSM, which will consequently increase its use in feeding monogastric animals. The attempts that have been undertaken include breeding strategy, optimisation, modernisation and better control of the oil extraction process, as well as technological treatments of seeds and meal. This review provides information on how RSM has evolved in recent years, as well as on its nutritive value, particularly protein, fibre and glucosinolate content. Techniques which have been used to improve the nutritional value of rapeseed products are also discussed. However, the used methods do not allow for full replacement soybean meal by RSM in monogastric animal nutrition.

“…During the drying, softening, rolling, steaming, and reserving processes, the value of the crude fat content of RSM as fed basis changes with the change of moisture content. Bojanowska reported that in comparison with fresh samples, significant differences in the crude fatcontent were observed in RSM after storage with increased saturated fatty acids and decreased unsaturated fatty acids [21]. However, as the utilization of RSM in swine diets is limited, relatively few studies are available on the crude fat content of RSM, and further research is needed.…”

Rapeseed Meal and Its Application in Pig Diet: A Review

et al. 2022

View full text Add to dashboard Cite

Rapeseed is the second largest plant protein resource in the world with an ideal profile of essential amino acids. Rapeseed meal (RSM) is one of the by-products of rapeseed oil extraction. Due to the anti-nutritional components (glucosinolates and fiber) and poor palatability, RSM is limited in livestock diets. Recently, how to decrease the anti-nutritional factors and improve the nutritional value of RSM has become a hot topic. Therefore, the major components of RSM have been reviewed with emphasis on the methods to improve the nutritional value of RSM as well as the application of RSM in pig diets.

“…Two classes of processes were considered as potential causes of this form of protective coating degradation: (1) Direct physical impact of oily fractions on the base and pigments of the coating and (2) possible effects of microbiological processes. The chemical composition of the biomass used in the experiment, previous studies [48,49], and literature data [50,51] indicate a decisive contribution of the microbiological factor to the development of this form of destruction. Previous studies on the degradation of rubbers and elastomers [19] under conditions of short-term exposure to oily fractions showed that the action of oily fractions is uniform over the entire exposed area.…”

Issues of Corrosion and Degradation under Dusty Deposits of Energy Biomass

The aim of the study is to identify and determine the role of microbial degradation taking place in dusty deposits in potential threats (i.e., destruction of protective coatings and development of corrosion) to the means of transport in conditions of transshipment of energy biomass. This paper presents the results of research on the impact of powdery fractions of wood biomass and biomass obtained from oil plants in the degradation of paint coatings and corrosion processes. During the research, exposure to simulated port climate, OM, SEM, and EDS studies were used. It has been found that the presence of the fraction containing protein compounds and amino acids (e.g., dust of rapeseed meal) stimulates the growth of microorganisms whose metabolism products favour the destruction of protective coatings and the development of corrosion. Under the same conditions, the destruction of protective zinc coatings has been observed. It was found that already 14 days of exposure to oily biomass deposits results in damage to paint coatings caused by microbiological processes. The 8-week exposure causes serious degradation of protective coatings and the base material itself. The biomass of wood origin, containing compounds of the tannin type, did not show as much aggressive activity as the biomass with protein compounds.
