Abstract

Purpose

Pumpkins are a rich source of essential nutrients, namely, β-carotene, minerals and vitamins, and they are therefore suitable for making functional juice. This study aims to develop pumpkin-based functional juice and assess the acceptability of the product by various consumers. In total, 55 per cent of the panelists disliked the pumpkin juice because of its strong off-flavor. Consequently, different blends of pumpkin juice with mango, orange, strawberry and green apple juices were prepared and evaluated for global appreciation and descriptive sensory analysis.

Methodology

Pumpkins, green apples, mangos, oranges and strawberries were obtained from the local market. Four mixtures of juices were prepared by mixing pumpkin and mango juice (750/250, v/v), pumpkin and green apple juice (750/250, v/v), pumpkin and orange juice (750/250, v/v) and pumpkin with strawberry and orange juice (750/125/125, v/v/v). The contents of moisture ash, fiber, carbohydrate, crude protein and lipids were estimated according to AOAC methods. β-Carotene, vitamin C and minerals were determined. A semi-trained panel consisting of 100 members assessed sensory characteristics of pumpkin juice and mixtures using a quantitative descriptive analysis method (QDA) for different attributes.

Findings

The findings show that the moisture, crude protein, fiber, ash and carbohydrate contents indicate that the developed pumpkin juice was rich in these essential nutrients. The fiber value in our study was lower than the value previously reported for pumpkin. The content of β-carotene and vitamin C in the developed pumpkin juice was considerably higher than that reported previously for fruits. The values of calcium and iron of the current study were much higher than those previously reported in vegetable juices and mixtures. The sensory results revealed that the developed pumpkin-based juice blends are acceptable by the consumers.

Originality value

This study was carried out to develop a suitable formula for preparing functional juices from pumpkin, which is not consumed willingly by children and the elderly; the authors aimed to improve its taste and flavor by mixing it with different fruit juices. The results demonstrated that pumpkin juice is rich in essential nutrients such as vitamins, minerals and antioxidants, suggesting its health-promoting potential. Mixing pumpkin juice with mango juice or orange and strawberry juices significantly improved the sensory quality of the products. Strikingly, the formulated pumpkin juice mixtures received good acceptance and appreciation by children and the elderly, which could promote its use as a functional juice. Generally, pumpkin-based juice blends are rich in vitamins, minerals and antioxidants and can therefore be consumed as a functional beverage with potentially increased health-promoting characteristics. Using pumpkin for developing functional juices could add commercial value to pumpkins. Future studies should specifically focus on large-scale production and commercialization of these juice mixtures.

Abstract

Purpose

The purpose of this paper is to assess the growth and viability of Lactobacillus rhamnosus GR-1 (L. rhamnosus GR-1) in carrot juice (CJ), carrot apple juice (CAJ), carrot orange juice (COJ) and carrot beet juice (CBJ) over 72 h of fermentation and 30 days of refrigerated storage at 4°C. The secondary objective is to evaluate sensory properties.

Design/methodology/approach

Four vegetable juice samples were inoculated with the probiotic strain L. rhamnosus GR-1 and fermented for 72 h. To observe the samples’ storage ability, the samples were refrigerated for 30 days. Microbial enumeration was conducted throughout the fermentation and storage periods to determine the viability of L. rhamnosus GR-1. Sensory evaluation with 106 participants was also conducted to assess the consumer acceptability of the vegetable juices.

Findings

All tested samples achieved mean microbial counts of at least 109 CFU/ml. During the 72-h fermentation period significant differences in microbial counts in juices CJ (p = 0.001), CAJ (p = 0.031), COJ (p = 0.047) and CBJ (p = 0.001) were observed. Over the 30-day storage period, significant differences in microbial counts were only found in juices CJ (p = 0.001) and COJ (p = 0.019). A significant decline in pH (p = 0.001) was also observed during 72 h of fermentation and 30-days of cold storage. Sensory evaluation of all juices showed significant differences in sensory attributes such as appearance (p = 0.001), flavour (p = 0.001), texture (p = 0.001) and overall acceptability (p = 0.001). Sensory results showed that the probiotic CBJ and CJ had the highest hedonic scores for flavour, texture and overall acceptability (p = 0.001) among participants. This study demonstrated that non-dairy vegetable juices could be an alternative to dairy-based probiotic products.

Originality/value

Commercially available probiotic dairy-based foods make up a large sector of the consumer market. However, the growing consumer interest in healthful eating has led to an increased demand for plant-based products. The probiotic L. rhamnosus GR-1 provides numerous therapeutic benefits, such as reducing the recurrence of bacterial vaginosis, yeast and urinary tract infections. The results of this study may have a significant influence on the health of individuals, especially in less economically developed countries.

Abstract

Purpose

Beer-bananas in Central Uganda are important for smallholder farmers’ livelihoods, especially for those that process the banana into beer and spirits. The purpose of this paper is to understand how actors in the beer-banana value chain are affected and how they are managing disease has become an important issue since the outbreak of the bacterial banana disease Xanthomonas Wilt.

Design/methodology/approach

The authors conducted an exploratory study focusing on producers of beer-bananas; brewers and non-brewers, and on retailers in Central Uganda and in Kampala. The authors conducted surveys with these value chain actors and we used baseline data, collected through a household survey in the project sites.

Findings

Results showed that Banana Xanthomonas Wilt (BXW) has drastically reduced productivity of beer-banana systems, resulting in reduced sales volumes of beer-bananas and processed products and consequently reduced incomes. Application of disease control measures was generally higher among those farmers that brew.

Research limitations/implications

This being an exploratory study, the samples for the different value chain actors were rather small. Future research should address: product quality and opportunities for differentiation; effects of beer-banana processing on rural communities; adoption of BXW control measures.

Originality/value

Beer-bananas are often neglected in research; this paper shows that is unfounded since beer-banana production and processing are important for many people’s livelihood. More insight into what motivates farmers to control the disease is essential to protect these people’s livelihoods.

Abstract

Purpose

The purpose of this paper is to review the advanced technologies and approaches for utilization of waste generated in dairy industry. Whey is highly contaminated, with a high organic load around 100,000 mg O2/L COD (chemical oxygen demand), and is not used for further processing. The waste generated in different food industries can be utilized in different value addition product with the help of advanced technology.

Design/methodology/approach

Major well-known bibliometric information sources are the Web of Science, Scopus, Mendeley and Google Scholar. Several keywords like nutrition value of whey, whey utilization, whey valorization, whey technologies, whey beverages, fruit-based whey beverage, carbonated beverage, probiotic or alcoholic beverages, herbal beverage, fermented beverage and current scenarios were chosen to obtain a large range of papers to be analyzed. A final inventory of 126 scientific sources was made after sorting and classifying them according to different criteria based on topic, academic field country of origin and year of publication.

Findings

The comprehensive review of different literature, data sources and research papers seeks to find and discuss various sustainable solutions to this huge waste generated from milk industry. The sustainable use of whey for production and conversion in different types of products can uplift the bio-based economy of industries and thereof national/international economy. The recent upsurge in consumer interest for health-promoting products has opened up new vistas for whey beverages and other whey products research and development.

Originality/value

The paper draws out different sustainable characteristics and technology of whey products available in market, as well as potential products to be launched in the market. Interestingly, over the past few years, dairy industries have applied various technologies to process cheese whey and are in search of new products which can be prepared from the by-product. This review discusses on the recent research development of whey valorization with particular reference to technologies used in the addition to their commercial availability and a way forward.

Abstract

Purpose

The purposes of this paper are to extend the shelf life of juice/fluids and reduce the thermal damage of their functional components. Thermal processing is a universal method used to extend the shelf lives of juice/fluids. However, combination processing thought to be beneficial in extending the shelf life with least possible thermal damage. The shelf life of the two thermally processed appetizer beverages, i.e. ginger beverage and karpurvalli beverage was established up to six months.

Design/methodology/approach

Both appetizer beverages were processed using irradiation in combination with heat treatment. A short thermal treatment at 95°C for 5 minutes was given to the bottled beverages, and these were then irradiated with different dosages of 1, 2 and 3 kGy. The samples were stored at room temperature (18-33°C), as well as at 37°C and periodically analysed for changes in pH, acidity, TSS, browning index, antioxidant activity and gingerol/carvacrol contents and for their microbiological quality.

Findings

The results revealed that in both products, the antioxidant activity and the gingerol/carvacrol content reduced, making these microbiologically safe up to eight months. However, combination of irradiation was not found suitable for the appetizer beverages due to more than 50 per cent losses in the functional components.

Research limitations/implications

The combination of thermal and irradiation processing was effective to ensure microbial safety and extend the shelf life of beverages. However, it may not be suitable for preserving all functional properties.

Originality/value

The outcome is result of original work done, and information provided can be a preamble to the researchers targeting improved stability of functional beverages.

Abstract

This paper presents a case study conducted in a sugar mill. The multi‐level lot‐sizing model suggested by Gunasekaran where the whole manufacturing system modelled as a function of total system cost (TSC) is used for this application. This study deals with minimising the TSC of a multi‐stage, multi‐facility and multi‐product manufacturing system in which the buffer in between the stages is not allowed. The model is applied to find out the TSC and hence the fluctuating purchase prices of raw material. The consequence of implementing different costs that may occur due to change in government policies is analysed. This work has been carried out in an IBM/PC compatible system.

Abstract

Purpose

The purpose of this study was to evaluate beet and orange mixed juices added with lyophilized Lactobacillus acidophilus probiotic culture.

Design/methodology/approach

Two formulations of probiotic beet and orange mixed juices (1:1 e 1:2 v/v) were prepared, stored at 4°C for 28 days and were evaluated for probiotic survival, physicochemical stability, antioxidant activity and sensory acceptance. The probiotic culture was added in a lyophilized form and was not propagated in culture media or juice.

Findings

Physicochemical characteristics (pH, titratable acidity, total soluble solids and color) and antioxidant activity showed no undesirable alterations during storage. The number of probiotics followed established minimum requirement for probiotic foods (109 CFU/200mL) during the 28 days of storage. The juices showed good sensory acceptance and purchase intention, especially regarding the color of the product.

Practical implications

The beet and orange mixed juices are suitable carriers for L. acidophilus with a shelf life of at least 28 days at 4°C.

Originality/value

Direct addition of the probiotic culture could result in high probiotic survival in mixed juices, dispensing the propagation step.
