Sugarcane Ethanol Production. Sugarcane feedstock mainly consists of sugar in the form of disaccharide (sucrose), which is readily fermented into ethanol by S. cerevisiae. The process of making ethanol from sugarcane starts when cane stalks are crushed to extract a sugar-rich cane juice. When cane stalks passed through extractor/expeller, cane ...

Depending on processing of sugar cane juice two kinds of molasses have been reported in the literature. They are 'Blackstrap molasses' and 'High test molasses.' Blackstrap molasses has been used principally in industrial alcohol production in distilleries. It usually contains 48 to 55% of sugars mainly sucrose.

The juice obtained from milling is clarified and heated to 75 °C, followed by treatment with SO 2 for bleaching. Afterward, the juice is mixed with lime to remove all the impurities. Adjusting the pH to 7, the juice is heated in a series of heat exchangers to its boiling point. The juice is further evaporated to obtain a concentrated syrup.

Making cheese is both an art and a science. Cheesemakers rely as much on measurements of pH levels and inoculations of specific molds as they do their own senses of sight, touch, and smell. There are six important steps in cheesemaking: acidification, coagulation, separating curds and whey, salting, shaping, and ripening.

Jam, jelly and marmalade are based on preservation by high sugar concentration. All fruits can be converted to jam by mashing or slicing it fine, adding an approximately equal amount of sugar, and simmering until it reaches proper concentration or gel at 218° to 222°F (103°-105°C). A process flow chart for jam making is given in Figure 4.

Aug 11, 2022At the mills, the sugar cane is first cut up into small pieces, and then crushed to extract its juice. The juice is clarified by removing most of the impurities (sugar cane fibre and soil, for example). This sugar-rich solution is boiled down to a thick syrup to which tiny "seed" sugar crystals are added and grow to larger crystals of raw sugar.

Machines are used to harvest the sugar canes from its base. The cut cane is then transported to the sugar mill for processing. The canes are placed onto a conveyor belt that takes the cane through two separate washes. Hammers break the canes down into smaller pieces. Canes go through a milling tandem that extracts the juice from the canes.

Sugar cane must be crushed to extract the juice. The crushing process must break up the hard nodes of the cane and flatten the stems. The juice is collected, filtered and sometimes treated and then boiled to drive off the excess water. The dried cane residue (bagasse) is often used as fuel for this process.
