ABSTRACT The effort to develop yogurt is by reprocessing it into ice cream products. The yogurt added to ice cream is made from fermented milk using probiotic LAB. Foods that have the potential to grow probiotics are foods that contain prebiotics; mung beans are one of the foods that contain α-galacto-oligosaccharides so that they can act as prebiotics. This research was conducted experimenta…
ABSTRACT Sago bark is a byproduct of the sago starch filtering process that contains lignocellulosic components. The separation of these lignocellulosic components can be achieved through a lignification process. One chemical method of delignification employs an organosolv solvent. This research aims to determine the optimal concentrations of formic acid and acetic acid to achieve the highest …
ABSTRACT Red cayenne pepper is one of the commodities in Riau that has a shelf life that only a few days at room temperature, then it needs to be handled after a post harvest. Edible coating is a thin layer that will prevent the water movement then the respiration process is inhibited. Edible coating can be made by starch, such as corn starch because it has a high content of amylose and amylop…
One of the problems that occurs in Ultisol soil is the low availability of P because it is bound by bonds of Al, Fe and clay minerals. The application of arbuscular mycorrhiza and solid compost to Ultisol soil in the pre-nursery is very important to increase nutrient uptake and growth of oil palm seedlings. The aim of this research is to study the response of P uptake and growth of oil palm…
The addition of synthetic PGRs, especially in in vitro media, has been widely reported with various advantages and disadvantages. Although synthetic PGRs are more practical in their application and their PGR content is known for certain, synthetic PGRs have several disadvantages such as being quite expensive and also having side effects on health and the environment caused by residues from the …
ABSTRACT Shampoo contains active substances and additives such as viscosity thickeners, surfactants, foam stabilizers, preservatives and other additives. One of the things that need to be considered in formulating shampoo includes the viscosity. Carbopol 940 has a high viscosity as a thickener.
