ABSTRACT Sago starch is one of the carbohydrate-producing plants extracted from the pith of the stem. The use of natural sago starch as a source of starch in food products is still limited because it has deficiencies in physicochemical characteristics. Modified combination of fermentation and annealing method was carried out on sago starch which has limitations in physicochemical characteristi…
ABSTRACT Sugar palm starch pulp is waste from the processing of palm starch which contains cellulose, hemicellulose and lignin. The cellulose isolation process is carried out to remove lignin and hemicellulose content through a delignification process using sodium hydroxide. This study aims to obtain the optimal extraction time used in the delignification process with sodium hydroxide solution.…
ABSTRACT Wet noodles that are widely consumed are usually made from wheat raw materials. The use of wheat flour results in the need for diversification of food ingredients. One of them, moringa leaves, has high protein and antioxidant values. The purpose of this research is to get the concentration of moringa leaf extract in making wet noodles and get the physicochemical and sensory characteri…
ABSTRACT Indonesia is known as an agricultural country that relies heavily on the agricultural sector, one of which is oil palm plantations. Oil palm plants produce oil palm trunk waste which can be used as a substrate for the growth of lactic acid bacteria (LAB). One of the LAB strains that can produce amino acids and antioxidants is Enterococcus faecalis. The purpose of the research was to d…
ABSTRACT Lemang bamboo is classified as a semi-wet food product with moisture content ranging from 10-40%, and water activity (Aw) ranging from 0.65-0.90 so that it can be used as a medium for the growth of microorganisms that can cause damage. This study aims to determine changes in chemical, microbiological and sensory characteristics of bamboo lemang in various types of packaging (banana l…
Universitas Riau ABSTRACT Marshmallow is a type of candy that has a soft foam like texture and melts in the mouth when eaten. The use of natural dyes such as butterfly pea flower extract and the addition of gelatin concentration in making marshmallows is expected to produce good marshmallow characteristics.
