The need for production of more health‐promoting and affordable drinks prompted the idea of incorporating probiotic bacterial isolates into ginger‐based beverages. The purpose of this paper is to evaluate the viability of two probiotic bacterial isolates (Lactobacillus plantarum and Lactobacillus bulgaricus) in ginger and ginger with garlic beverages and to determine in vitro inhibition of Escherichia coli NCIB 85 and Staphylococcus aureus NCIB 8586 (common food‐borne pathogens) by the probiotic beverages.

Inoculation of sterilized ginger‐based beverages with isolated Lactobacillus strains was carried out and subsequently stored at ambient temperature (27 ± 1°C) and refrigeration temperature (4 ± 1°C) for four weeks. Lactic acid bacteria count of each probioticated sample was determined at intervals using standard method. In vitro inhibition of the food‐borne pathogens by the probiotic beverages was determined with broth culture method.

Results revealed the log count of Lactobacillus plantarum in the ginger beverage to be from 9.11 to 8.09 and 7.82 cfu/ml at ambient and refrigeration temperatures, respectively, at the fourth week of storage. Log count of Lactobacillus bulgaricus also ranged from 7.68 to 2.25 cfu/ml after four weeks of storage at ambient temperature while it remained at 5.57 cfu/ml after three weeks of storage at refrigeration temperature. L. bulgaricus however, failed to survive beyond three weeks in refrigerated storage. Similar trend of viability was exhibited in ginger with garlic beverage. Probiotic ginger, and ginger with garlic beverages inhibited the growth of E. coli and S. aureus to varying degrees during the period of storage.

Ginger‐based beverages could therefore be used as carriers of probiotic bacteria and thus serve as health drinks for consumers of different socio‐economic strata.

The objective of this study is to identify the optimal product design attributes for a range of chilled probiotic orange juice beverages, and to evaluate the contribution of market‐oriented research methodologies to the development and strategic marketing of innovative functional beverages.

A conjoint‐based survey was administered to 400 purchasers of chilled orange juice in both Dublin and Cork between May and September 2004.

New product development (NPD) opportunities exist for probiotic juice‐based beverages, although functionality should not be relied on solely to leverage a competitive advantage.

The survey sample only included primary purchasers of chilled orange juice, owing to the increased importance of the chilled orange juice category in Ireland. Further research that would incorporate purchasers of ambient orange juice, and end‐users of both chilled and ambient orange juice in Ireland, as well as across European states for a cross‐cultural perspective, would prove beneficial to both manufacturers and retailers.

Advanced market‐oriented research methodologies during the concept stage of the NPD process can assist both food and beverage firms and retailers to develop and market functional foods and beverages that more closely meet consumers' needs and values.

This research can assist beverage manufacturers to optimally design a range of chilled probiotic orange juice beverages targeted at specific market segments, and provide guidance for effective positioning, communication and pricing strategies of innovative functional beverages.

The purpose of this paper is to report on a study that examines the sale and provision of healthy beverages across four sectors of the hospitality industry: restaurants, cafes, pubs and quick-service/takeaways. Specifically, the research investigates perceptions of demand for healthy products, challenges to distribution and strategies for increasing supply. In addition, business managers’ attitudes and behaviours with regard to offering healthy beverages, including probiotic beverages (i.e. kombucha, kefir, etc.), are explored, as these are among the fastest growing drinks category.

Data were collected in 2018 through 400 telephone interviews with hospitality business managers from Australia (n=250) and New Zealand (n=150). Data were analysed through SPSS and Stata using descriptive statistics and Probit regression, with a binary outcome variable of “sell/ do not sell” probiotics to consumers.

Results suggest that the business’ decision to sell healthy beverages is influenced by perceptions of consumer demand, profit margins, shelf life of the products and if locally produced.

The findings from this exploratory study present new insights on how hospitality firms respond to consumer demand for healthy options, and the factors influencing their decision to incorporate healthier beverages in their menus.

In a developing country like India, consumers are shifting from high-energy diet to balanced nutritional diet, which enhances the metabolic, physiological, functional and health benefits of consumers. The growing self-care and health-embracing population made the probiotic sector as lucrative market for functional food manufacturers and suppliers. Therefore, an analysis is required to understand consumers’ knowledge and buying behavior regarding probiotic products for product innovation and development.

Awareness, knowledge and consumption patterns of probiotic products were investigated among randomly selected 306 consumers in the Sonipat city of Haryana, which comes in the proximity of national capital, i.e. Delhi, India. A structured questionnaire with exploratory characteristics was developed and face-to-face interviews were conducted as a part of data collection.

The inference is that there is immense potential for the probiotic fruit beverage market as a higher proportion of the population was interested in probiotic products delivered with fruits as a base matrix followed by dairy products. Further, government’s initiation and support are required not only for manufacturing such health-beneficial products having therapeutic value but also to spread awareness regarding the necessity of including such products in the meals of the growing children.

The study shows changing customer attitudes toward probiotic products and sheds light on consumers’ preference on the medium (food matrix) of probiotic delivery, thereby exploring market opportunities in the area of the functional food sector.

The authors aim to report a novel encapsulation technology for probiotic bacteria, through which L. casei CRL431 cells have been successfully delivered in shelf stable dry and intermediate moisture foods.

Manufacturing of the probiotic ingredient involved a proprietary technique using combination of controlled fermentation of the L. casei CRL431 cells, encapsulation in a food grade matrix and drying under controlled parameters.

The developed ingredient was stored at 25°C for a period of 12 months. The loss in cell viability was 1.9 log cfu g-1 after 12 months and maintained at 8.3 log cfu g-1. In vitro gastric juice and bile salts incubation revealed that the probiotic cells were better protected within the encapsulated than in the free form. The survival of the encapsulated cells was 5.0 and 2.1 log cycles higher than free cells in gastric juice and bile salt solution respectively. Fortification of probiotic bacteria did not have any negative impact on the sensory qualities of the foods mentioned above.

The developed technology is only applicable for fortifying dried or intermediate moisture foods with beneficial probiotic bacteria. The water activity of the products needs to be ranged from 0.2 to 0.5. A higher moisture contained food will lead to bacterial proliferations, product spoilage and loss in storage viability of the fortified probiotic cells.

A general guideline issued by FAO/WHO states that any good effect of probiotic bacteria on human health can be obtained only if consumed at a level of 10^7 to 10^8 viable cells per day. Delivery of such a concentration of live probiotic cells is particularly challenging in the case of long shelf life foods. As shown in the results, the authors' probiotic powder is able to deliver over 100 million live cells per gram after 12 months of ambient storage. Even the foods fortified with this powder are able to deliver over 1 million cells per gram after six months of ambient storage.

The developed technology rightly identified the gap for fortifying probiotic bacteria into foods stored under ambient conditions which is a real hindrance to reach out to consumers particularly in the developing countries where refrigerated supply chain and storage are not yet established in an efficient way. It is believed that millions of people in developing countries with a tropical climate would be benefited with the goodness of probiotic bacteria using the help of this technology.

The research work presented here is completely original and in-house research output of the Riddet Institute, Massey University, New Zealand. A successful commercialization of this new novel technology is deemed to be of very high value to any institution.

This research aims to generate consumer knowledge to facilitate the development of new product concepts with optimal product design attributes for new fermented functional cereal beverages (FFCBs) with high market potential.

This research employed a sequential mixed research approach which integrated both qualitative and quantitative methods. A total of 12 in‐depth interviews and three focus groups were carried out to identify product concepts for new FFCBs. A conjoint model (n=299) was then developed to evaluate product‐specific factors that influenced consumer acceptance of FFCBs.

Potential target consumers of FFCBs were more likely to be young females who had relatively high educational and income levels. “Flavour” and “health/nutritional claim” were found to be the most important product attributes for consumers. The simulation analysis predicted two FFCB concepts for target consumers.

As there is a limited range of FFCBs on the market, the concept of FFCBs may be novel to consumers. Further research would be beneficial that closely integrates the strategic marketing of FFCBs with sensory analysis conducted on a range of these beverages.

During the early stages of the new product development (NPD) process, a market‐oriented research methodology can help optimise product concepts in terms of product attributes that drive consumer acceptance.

This paper provides an important insight into the significance of market‐oriented knowledge generation techniques for the development of new cereal‐based functional foods. It provides market‐oriented information on FFCBs which can be valuable for food manufacturers to maximise NPD performance and to gain competitive advantage in the functional beverages market.

This study aims to evaluate the effect of probiotic provitamin A cassava hydrolysate with Lactobacillus rhamnosus GG (hLGG) on weight and lipid profile of Wistar rats and its glycemic index using Wistar rats and human subjects.

Adult male Wistar rats (n = 40, 120–150 g) were orally administered provitamin A cassava hydrolysate with 1 × 10¹⁰, 2 × 10¹⁰ and 4 × 10¹⁰ CFU/g encapsulated or CFU/mL free Lactobacillus rhamnosus GG for 30 days, during which weight and lipid profile of rats were monitored. Blood glucose levels of rats and human subjects were also measured in Oral Glucose Tolerance Test to determine the Glycemic indices of hLGG.

Rats administered the highest doses of free or encapsulated hLGG [(4 × 10¹⁰ CFU) (PHE4 and PHF4, respectively)] had the lowest (18.2 ± 0.7 and 8.0 ± 0.6%, respectively, p < 0.001) percentage body weight gain compared to control (40 ± 0.6%). Lowest cholesterol and triglyceride (42.4 ± 0.5 and 44.4 ± 0.7 g/dL, p < 0.001, respectively) were observed in rats administered PHE4, with the lowest plasma glucose concentrations in PHE4 and PHF4 groups (43 ± 1 and 49 ± 0.7 g/dL, p < 0.001, respectively). Oral Glucose Tolerance Test for rats and human subjects showed lower peak blood glucose levels and glycemic indices in hLGG groups compared to controls in a dose-dependent manner.

Consumption of soft drinks, which supply non-nutritive energy, may lead to degenerative metabolic disorders such as obesity and diabetes. Beverages with probiotics such as Lactobacillus rhamnosus GG, on the other hand, offer a positive weight management approach. Development of non-dairy beverages such as provitamin A cassava hLGG is ongoing. Provitamin A cassava hLGG showed its ability to control weight gain, blood glucose levels and serum lipids. Thus, the beverage can be consumed as a healthy alternative to soft drinks and for weight management.

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.

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.

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.

Interest in probiotic food products has constantly increased due to the awareness on importance of gut microbiome; an increasing demand has encouraged the development of other matrices such as cereals, vegetable and fruit juices to deliver probiotics. The purpose of this paper is to standardize and evaluate a ready to serve probiotic oats milk drink fermented with microencapsulated Lactobacillus plantarum to be further used as a therapeutic module.

Fermentation of oats milk extract with microencapsulated L.plantarum was subjected to various trials in making it favourable for consumption and tested for sensory characteristics, physicochemical parameters, nutrient content, viable colony count and shelf life.

Fermented oats milk drink with 3% inoculum of microencapsulated L.plantarum was able to achieve desirable level of 2.5 × 10⁸ and 2.3 × 10⁸ colony forming units (CFU)/mL for spice and strawberry flavoured drink, respectively. Antioxidant property significantly increased after fermentation showing inhibitory effect against 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) assay (p = 0.05).

Analysis of all the parameters were conducted only with three samples; this was the potential limitation identified in this study as large sample size always be a better representative of the results.

Spice and strawberry flavoured nondairy oats milk drink facilitated to be a suitable carrier for microencapsulated L. plantarum with good sensory attributes, low fat, moderate calorie, high fiber content, antioxidant potential and a shelf life of two-week period at 4°C.

The developed ready to serve, spice and strawberry flavoured nondairy oats milk drink with compactly packed functional components inclusive of beneficial probiotic organisms, ß-glucan and antioxidants can be prescribed as a therapeutic food for many clinical conditions and would serve as a good probiotic option for vegans.
