Castor Meal to Replace Soybean Meal as Lamb Feed

Researchers at Brazil conducted a study to understand the effect of replacement of soybean meal by wet or dry castor bean meal in diets of feedlot lambs. They assessed animal performance, carcass traits, intake, digestibility and hepatic function.

Control animals were fed with soybean meal while lambs for test were casfed with dry or wet castor meal treated with calcium hydroxide for 70 days. Lambs were slaughtered and evaluated at the end of 70 days. Dry matter intake and digestibility, final body weight, average daily gain and carcass weights were not affected by the substitution of soybean meal by castor source.

Serum levels of aspartate aminotransferase and alanine aminotransferase enzymes did not differ among treatments indicating no effect of treated CM on hepatic function.

The results show that the castor meal can completely replace soybean meal in the diet of finishing lambs without negative impacts.

100% Biobased Polymer as Food Contact Substance

Evonik, German-based specialty chemicals company, has received approval for its foodmq1 contact substance ‘VESTAMID Terra DS16 natural’. VESTAMID Terra DS16 is a biobased polymer belonging to the family of PA1010 polyamides.

The polymer is based on renewable feedstock. The starting material is the castor bean and its oil derivatives. VESTAMID Terra DS is based on polyamide 1010, which is the polycondensation product of 1, 10-decamethylene diamine (D) and 1, 10-decanedoic diacid (sebacic acid – S). Both of these are derived from castor oil, which means that Terra DS is 100% Bio based.

Another polymer named Terra HS, based on polyamide 610, contains polycondensation product of 1, 6-hexamethylene diamine (H) and 1, 10-decanedoic diacid (sebacic acid – S) and is 63% biobased. Terra HS is already being approved in the EU and USA for food contact with non-alcoholic food materials.

Study of the Mechanical, Thermal Properties and Flame Retardancy of Rigid Polyurethane Foams Prepared from Modified Castor-Oil-Based Polyols

A team of researchers from China conducted study on mechanical, thermal properties and flame retardancy of rigid polyurethane foams (PUF) prepared from modified castor oil (MCOHomepagecarroussel-research1) based polyols. The polyurethane foam was prepared in two stages. The first stage is the conversion of castor oil into glycerides by alcoholysis with glycerol and pentaerythritol. Next stage is the synthesis of polyester polyols by condensation alcoholysis of castor oil and phthalic anhydride. Results from various analyses showed that components of the MCOs and commercial polyester polyol PS-3152 are similar in their foaming behaviour. Results from analyses like mechanical testing, flame retardancy testing, thermogravimetric analysis and cone calorimetry showed that PUF from modified Castor oil based polyols had a better mechanical properties and thermal conductivities than PS-3152 based Polyurethanes. High thermal stability is exhibited by MCO based PUFs, during pyrolysis.

It is also found that addition of ammonium pyrophosphate decreased their heat release rate, total heat release and mass loss, thereby having synergistic effect with phthalic anhydride polyester polyols. All of these unique properties of MCO-modified rigid PUFs were correlated to the structures of these PUFs.

These findings may lead to the development of a new type of polyurethane foam using castor oil.
