Commercially processed sauerkraut, packaged in plastic bags, was evaluated for product stability following storage at 2, 20, 32 C. When stored at 2 C in the presence of benzoic acid and potassium metabisulfite, the product was stable for more than 8 months, whereas at 20 and 32 C the shelf life was reduced to 20 and 13 weeks, respectively. The reductions in shelf life were due to development of excessive discoloration (browning) and objectionable flavor formation. These defects appear to be caused by chemical rather than microbiological actions. In addition to serving as effective anti-microbial agents, the chemical preservatives (presumably sulfur dioxide) showed protective effects in retarding losses of naturally-occurring ascorbic acid found in sauerkraut. Under similar temperatures of storage, fresh sauerkraut containing no chemical additives had shelf life values of 22, 1.5, and 0.75 weeks, respectively. When stored at 32 and 20 C, the major defects (swollen or broken bags) were attributed to the actions of yeasts. Storage at 2 C markedly arrested and reduced viable yeasts counts, thereby extending the shelf life of the bagged product.

Natural Preservatives

Sugarcane juice is liquid extract as a drinking beverage in India, possesses therapeutic value. Stability or shelf life is very less due to spoilage or degradation of sugarcane juice because of presence of simple sugar in sugarcane juice. Microorganisms like bacteria prone to degradation of sugarcane juice. Which convert sucrose into dextran as deteriorating agent. Shelf life or stability can be improved by using natural preservatives also chemical preservatives; having a therapeutic value. In this article improvement of stability of sugarcane juice by using natural preservatives such as lemon extract, ginger extract, also may be moringa extract over the chemical preservatives. Citric acid in lemon extract acts as antimicrobial agent while ascorbic acid in ginger extract both improves stability of sugarcane juice. Stabilization of sugarcane juice improved by using naturally obtained preservatives up to several days with good quality.
