Biochemical Composition and Shelf Life Study of Mixed Fruit Juice from Orange & Pineapple

Development retort pouch packaged Ramasseri idli was undertaken with specific objectives of standardisation of thermal process in retort pouch package, shelf life study and quality evaluation. The Ramasseri idli, an indigenous cereallegume based food of south India, was procured and packaged in retort pouches with one idli in each pouch. The idlis were pasteurized at different time temperature combinations to achieve desired F0 values (110°C for F0=3 min, 110°C for F0=6 min 100°C for F0=3 min, 110°C for F0=6 min). After thermal processing the pouches were stored for shelf life studies under ambient storage (28°C) and refrigerated storage (7°C). The processed product was analysed for microbial and physico-chemical qualities viz; moisture content, pH, water activity, colour and texture using standard procedure at regular intervals. Based on physico-chemical characteristics and sensory evaluation, the thermal processed Ramasseri idli at 100°C for F0=6 min and stored under refrigeration showed best results up to three week of storage among the four treatments. The microbial analysis also showed that the product was safe up to 3 weeks of storage.

Cocos Nucifera L

Cocos nucifera L. (Family Arecaceae) commonly known as coconut, is an important fruit crop in the tropical countries.The objective of this study was to develop coconut chips with different flavours from tall, dwarf and breed varieties of coconut and to evaluate organoleptically. Also nutrient analysis of three varieties of coconut was carried out followed by the shelf life study of coconut chips. Three varieties of coconut were selected namely tall, dwarf and breed. Plain, sweet and spicy coconut chips were prepared from these three varieties and it was compared with that of the standard namely conventional traditional variety of coconut. Traditional variety is most suitable for making plain coconut chips with white pepper flavour (PSV1) followed by dwarf, tall and breed varieties of coconut. Mean acceptability score of sweet coconut chips- osmotic dehydration method (SwSV1) revealed that traditional variety was good followed by dwarf, tall and breed varieties of coconut. Sweet coconut chips prepared without osmotic dehydration method traditional variety was good followed by tall, dwarf and breed varieties of coconut. Traditional variety of coconut chips was good for making spicy coconut chips- white pepper flavour (SpSV1) followed by breed, dwarf and tall varieties of coconut. Spicy coconut chips- chilli powder (SpMV2), traditional variety of coconut chips was good followed by dwarf, breed and tall varieties of coconut

O objetivo desta pesquisa foi estudar a vida-de-prateleira de produto elaborado com garapa, parcialmente clarificadaestabilizada, e suco de maracujá (5%). A mistura foi adicionada de antioxidante, conservante e espessante em concentrações pré-estabelecidas. Após pasteurização, o produto foi resfriado, embalado em garrafas de polietileno tereftalato (PET) e armazenado sob refrigeração pelo período de um mês. Foram realizadas determinações microbiológicas (Contagem Padrão, Contagem de Bolores e Leveduras, Coliformes Totais e Fecais), físico-químicas (pH, ºBrix, acidez, relação Brix/Acidez, teor de ácido ascórbico, turbidez), e sensoriais. Os resultados da análise sensorial, considerados os mais relevantes para a pesquisa, indicaram que o produto (mistura de garapa parcialmente clarificadaestabilizada com suco de maracujá) pode ser elaborado e comercializado por até quinze dias sob refrigeração, pois as condições do processo permitiram a manutenção da qualidade microbiológica e sensorial. O teor de ácido ascórbico manteve-se em bom nível até o final da estocagem, com perda de apenas 20% em relação ao teor adicionado. SHELF-LIFE STUDY OF A BEVERAGE ELABORATE BY BLEND OF PARTIALLY CLARIFIED-STABILIZED SUGAR-CANE JUICE AND NATURAL PASSION FRUIT JUICE Abstract The objective of this research was to study the shelf-life of a product elaborated with sugar cane juice, partially clarified-stabilized, and passion-fruit juice (5%). The blend was added of antioxidant, preservative and thickener in pre-established concentration. After pasteurization the product was refrigerated in polyethylene teraftalate (PET) bottles and stored for 1 month period under refrigeration. Microbiological determinations (Standard Count, Mould and Yeasts Count, Total and Faecal Coliforms), physico-chemical (ºBrix, pH, acidity, relation Brix/acidity, ascorbic acid content, turbidity) and sensorial were accomplished. The results of sensorial analysis, considered the more relevant for the research, indicated that the product (blend of sugar-cane juice partially clarified/stabilized with passion fruit juice) may be elaborated and commercialized until 15 days under refrigeration, because the conditions of the process allowed the maintenance of microbiological and sensorial quality. Ascorbic acid content maintained a good level until the end of storage, with lost of only 20% in relation to the concentration added.
