Preservation of sugarcane juice/Bottling of sugarcane juice

Introduction

Process to prepare ready to serve sugarcane juice

ICAR- Sugarcane Breeding Institute has developed a process to prepare ready to serve sugarcane juice having longer shelf life (up to three months). Sugarcane juice contains 18-20% solids and the juice obtained from it is a popular beverage. This natural product is highly beneficial for the health of the consumers. Raw sugarcane juice is a carbohydrate-rich, low acid food (about pH 5.0) and is susceptible to the growth of moulds, yeasts, spoilage bacteria and pathogenic bacteria. Freshly crushed juice ferment very quickly and cannot be preserved even for a few hours. Its colour changes to greyish or brownish very quickly. Major problem is the lack of hygiene during crushing operation which results in the contamination of the juice with a heavy load of micro-organisms. So, there was a great need for standard protocols for the preparation of long-term shelf stable ready-to-drink sugarcane juice. There are two methods by which juice can be preserved and bottled in either glass or plastic bottles. Juice properties are same as in fresh sugarcane juice. Preserved juice is ready to serve so it can be consumed at any time. Sugarcane juice has many health benefits due to its high nutritional value. Processing cost is low. Hence, it is an easy replacement of soft drink and other sugar added juice. Bottling of juice is important as it ensures availability of good quality of sugarcane juice throughout the year..

Method 1

Process of preservation of sugarcane juice by sulphitation:

We have standardized a protocol for preservation of sugarcane juice with 100 ppm suphitation treatment (permissible potassium meta bi sulphite level as per FSSAI). It can preserve sugarcane juice in refrigerated condition without any loss in colour, taste and consumer acceptability up to 90 days.

Different steps for sugarcane juice preservation process:

  1. Harvesting: Harvest the cane at 10 - 12 months crop age at ground level.
  2. Cleaning of canes: Discard the moulds and insect infected canes, clean the good canes and wash them with heavy flow of water to remove dirt, soil and microorganism. Handling area should be cleaned with disinfectant.Scrap the rind of canes. After rind scraping wash the cane with boiling water.
  3. Cleaning of juice crusher: Wash the crusher with boiling water followed by 10ppm sodium hypochlorite solution to avoid any contamination from the juice crusher.
  4. Crushing: Crush the canes in stainless steel crusher.
  5. Juice collection and filtration: Filter the juice through multi layer clean muslin cloth to remove the suspended and floating material and collect the juice in sterilized containers.
  6. Cleaning of glass bottle: Clean the glass bottle thoroughly and sterilize them before filling the juice.
  7. Sulphitation: Add 100 ppm potassium meta bi sulphite in the juice by weight.
  8. Bottling: Fill the juice in sterilized glass bottle under aseptic conditions and packed air tight. Allow for In-bottle pasteurization (65°C/25 min) followed by cooling to room temperature and then keeping in refrigerator.

Method 2

Process of preservation of sugarcane juice by steaming:

Different steps for sugarcane juice preservation process by steaming:

  1. Harvesting: Harvest the cane at 10–12 months crop age at ground level.
  2. Cleaning of canes: Discard the moulds and insect infected canes, clean the good canes and wash them with heavy flow of water to remove dirt, soil and microorganism. Handling area should be cleaned with disinfectant.Scrap the rind of canes. After rind scraping wash the cane with boiling water.
  3. Steam treatment of canes: Autoclave the cleaned canes for 15minutes at 7 psi.
  4. Cleaning of juice crusher: Wash the crusher with boiling water followed by 10ppm sodium hypochlorite solution to avoid any contamination from the juice crusher.
  5. Crushing: Crush the canes in stainless steel crusher.
  6. Juice collection and filtration: Filter the juice through multi layer clean muslin cloth to remove the suspended and floating material and collect the juice in sterilized containers.
  7. Cleaning of glass bottle: Clean the glass bottle thoroughly and sterilize them before filling the juice.
  8. Bottling: Fill the juice in sterilized glass bottle under aseptic conditions and packed air tight. Allow for In-bottle pasteurization (65°C/25 min) followed by cooling to room temperature and then keeping in refrigerator.
