Abstract

Purpose

The aim of this study is to develop a soy‐based cream cheese (SCC) with textural characteristics comparable to that of commercial dairy cream cheese (DCC) via the addition of microbial transglutaminase (MTG), soy protein isolate (SPI) and maltodextrin (MD).

Design/methodology/approach

Response surface methodology (RSM) was employed in this study to determine the effects of MTG, MD and SPI on firmness of SCC.

Findings

The second‐order model generated via RSM was significant with only a 9.76 per cent variation not explained by the model. The coefficient of regression revealed that MTG, MD and SPI showed significant linear effects (P<0.0001) on the firmness of SCC, while MTG and SPI showed significant quadratic effects. The model successfully predicted and developed a SCC model with similar firmness as that of DCC; via the combination of 2.57 per cent (w/w) of MTG, 19.69 per cent (w/w) of SPI and 19.69 per cent (w/w) of MD. Physicochemical analyses revealed that SCC possessed lower fat content, reduced saturated fatty acid and zero trans fat. Further rheological measurements revealed that SCC was more solid‐like at room temperature, but less elastic at refrigerated temperature compared to DCC. SEM and SDS‐PAGE analyses affirmed that the textural changes of SCC were attributed to MTG‐induced cross‐linking.

Originality/value

The research demonstrated that a non‐dairy cream cheese could be developed using soy. In addition, the SCC also contained better nutritional properties compared to its dairy counterpart.

Abstract

Purpose

The aim of this study is to examine the bioactive properties of lactobacilli‐fermented B‐vitamin soymilk, namely the in‐vitro antihypertensive property and bioconversion of isoflavone glucosides to aglycones.

Design/methodology/approach

Lactobacillus acidophilus BT 1088, L. fermentum BT 8219, L. acidophilus FTDC 8633 and L. gasseri FTDC 8131 were investigated for their bioactive potential and enhanced bioconversion of isoflavones in soymilk supplemented with individual B‐vitamins at a concentration of 1 mg/L.

Findings

The supplementation of thiamine, riboflavin, niacinamide, calcium pantothenate, biotin and folic acid enhanced the ACE‐inhibitory activity of lactobacilli in soymilk accompanied by a lower IC50 value compared to the control (P<0.05). The β‐glucosidase specific activity of lactobacilli was also enhanced on supplementation of B‐vitamins, leading to increased bioconversion of isoflavones in soymilk. The concentration of genistein was decreased, accompanied by an increased concentration of genistein on fermentation in the presence of thiamine, niacinamide, biotin, calcium pantothenate and folic acid. Additionally, the supplementation of niacinamide, calcium pantothenate, biotin and folic acid also led to lower concentrations of malonyl daidzin, indicating increased hydrolysis of malonyl daidzin to daidzin. Results from the present study indicated that the supplementation of B‐vitamins could enhance the bioactive potential and bioconversion of isoflavones in lactobacilli‐fermented soymilk.

Originality/value

This work has shown that the supplementation of B‐vitamins in lactobacilli fermented soymilk has exerted in vitro ACE‐inhibitory activity and increased the accumulation of bioactive isoflavone aglycones. To the authors' knowledge, this is the first evaluation reporting on such aspects.

Abstract

Purpose

The purpose of this paper is to develop a new salad cream formulation from a mixture of tofu and coconut oil for replacement of egg yolk and soy oil, respectively.

Design/methodology/approach

A salad cream formulation mainly composing of edible oil, egg and vinegar was formulated. Ratios of egg yolk and soy oil were replaced by tofu and coconut oil, respectively. The formulated salad creams were determined for pH, color, viscosity, protein and fat. Sensory acceptances of formulated products was evaluated by using a seven-point hedonic scale test and untrained panelists (n=30). The formulated salad creams were stored in a refrigerator for 14 days and determined for pH, color and viscosity.

Findings

The results showed that the formulated salad creams using the mixture of 50 percent tofu and 50 percent egg yolk (RE) by weight of egg yolk ratio in control presented 4.25+0.01 of pH which was comparable to control. The highest scores in the sensory test were obtained in the formula using 37 percent coconut oil by weight of salad cream. The formulated salad creams using tofu and coconut oil (REC) presented 4.42+0.03 of pH, 4.25+0.05 cm. of viscosity, and 87.36+0.44 (L), −1.13+0.04 (a), 16.32+0.22 (b) of color values. Protein and fat contents were 4.79 and 27.59 percent (w/w) in the REC, respectively. After storage under refrigerated, pH, color and viscosity of the modified product were less changed.

Originality/value

Replacement of egg yolk and soy oil with tofu and coconut oil in salad creams was feasible. The REC was less changed in its quality both fresh and after storage. It was accepted in sensory evaluation. The REC could prepare at home and being a food choice for consumers.

Abstract

Purpose

Among soy products, soy ice cream with neutral pH, high total solids contents and prebiotic oligosaccharides is an appropriate vehicle for probiotics. The purpose of this paper is to survey soy ice cream as a carrier for the efficient delivering of Lactobacillus casei, or L. casei.

Design/methodology/approach

Probiotic soy ice cream containing L. casei was produced via the powder of soy milk. The physicochemical and organoleptic properties of the product were assessed. Also, the viability of L. casei was surveyed over a 180-day period of storage at −25 °C.

Findings

The density characteristic of probiotic soy ice cream demonstrated a significant rise (P < 0.05). The result of the viability analysis showed significant alterations in the number of probiotics in this product after freezing and throughout the 180-day period (P < 0.05). The most noticeable drop was seen throughout the first 60 days about 1.83 logs after that the trend of survival of this probiotic strain leveled off over the next 120 days. Also, no significant differences were found in the organoleptic properties of both ice creams.

Originality/value

Soy ice cream with prebiotic elements protected the growing and activity of probiotic bacteria. The results showed that L. casei is a good probiotic for soy ice cream.

Abstract

In connection with the suggestion recently made in the BRITISH FOOD JOURNAL to the effect that a National Pure Food Association should be established it is of importance to call attention to the fact that a society describing itself as the “League for the Defence of Human Life” has been recently formed in Paris with the object of preventing the frauds practised by dishonest traders upon their customers. One of the obligations entered into by the members of the League is to discover and prosecute persons engaged in the sale of adulterated or injurious articles of food and drink. Judging from the recent reports of the proceedings of certain Parisian tradesmen it would appear that a society of this description has much scope for its operations in the French Metropolis, and, as we have suggested, a society with similar objects might with advantage be formed in this country, with branches in all the principal cities and towns. With the legal machinery placed at the disposal of local authorities, cumbrous, inadequate and weak as it is, much more might be done in the way of repression if only the responsible authorities could be brought better to appreciate their duty.

Abstract

This Bill was read a second time without a division in the House of Commons on July 23rd after a debate lasting nearly five hours. Opposition speakers, including particularly Dr. Edith Summerskill and Mr. Willey (former Parliamentary Secretaries to the Ministry of Food between 1945 and 1951), attacked the Government for having whittled down, very extensively, the contemplated Regulations (to be made when the Bill is on the statute book) dealing with cleanliness in the handling of food. As is generally known, the draft regulations have for several months been the subject of many discussions between trade organisations and the Ministry of Food. As a result, the Minister has decided to modify or drop several of the proposals which he had at first intended to carry into effect by regulations, and to substitute for some of them “codes of practice.”

Abstract

Salt (sodium chloride) is used in a variety of processed foods. It not only confers its own specific flavour on products, it is also used to enhance and modify the flavour of other ingredients. The reasons for using salt can be divided into three broad categories: processing reasons, sensory (taste) reasons, and preservative reasons. In some cases it performs all three of these functions, and in many situations the distinction between them is not clear‐cut.

Abstract

This is indeed the age of revolution, when timeless attitudes are changing and new ways of living being born. To most it is a bewildering complex, with uneasy forbodirtgs of the outcome. Improvement and change, there must always be—although change is not necessarily progress—but with unrest in the schools, universities and industry, one naturally questions if this is the right time for such sweeping reorganization as now seems certain to take place in local government and in the structure of the national health service. These services have so far escaped the destructive influences working havoc in other spheres. Area health boards to administer all branches of the national health service, including those which the National Health Service Act, 1946 allowed local health authorities to retain, were recommended by the Porritt Committee a number of years ago, when it reviewed the working of the service.

Abstract

The initial shock of devaluing the currency, after so many promises that it would not take place, has passed; only the uncertainty and apprehension remain. It seems an idle exercise to compare the present state of the country's economy with other periods in recent history, such as when in the first Labour Government, we went off the gold standard; at that time, shock was indeed profound and again, the French were cock‐a‐hoop, but the position was complicated by the huge inter‐indebtedness of the Allies in the First War. Or the first devaluation after the Second World War, but both periods were also characterized by public waste and profligate spending. Now, we have to obtain foreign loans and financial backing to keep going, and it is this aspect of the present devaluation which will probably far outweigh any positive advantages. The country's massive external debts were increased by approximately one‐seventh overnight, probably wiping out completely all the repayments made at such great effort since the War. Devaluation of the currency cannot be seen as anything but a grievous blow to the country, presaging hard times ahead for everyone. When promises were being made that devaluation would not take place, there can be little doubt that these were honestly made and, at the time, believed in, for no Government of a country with imports always exceeding exports, would impose such a burden on its people willingly. It must then have been forced upon them.

Abstract

Purpose

This paper aims to investigate the respective influences of price and country of origin (COO), as extrinsic cues, on consumer evaluations of product quality when all intrinsic cues are experienced through sensory (taste) perception.

Design/methodology/approach

Taste‐testing experiments were conducted (n = 263) using Brie cheese as the test product and a 3(COO) × 3(price) × 3 (fat content) conjoint analysis fractional factorial design.

Findings

Price was clearly found to be the most important attribute contributing to perception of Brie quality, followed by fat content. COO also exerted a substantial influence on respondents’ evaluation. In the case of this sensory experiment, reliance on the extrinsic cues tested was found to remain extremely robust even when all intrinsic cues (through sensory experience) were available for respondent evaluation when objective product quality was manipulated to three differing levels.

Research limitations/implications

The research presents a number of limitations. Convenience sampling was employed, limiting one's ability to generalize results. Further, the use of conjoint analysis for taste‐testing experiment methodology is limited, particularly with a sample of this size with objective quality manipulations that are quantified and precise. A laboratory environment is also a limitation.

Practical implications

The research demonstrated that, even when evaluating a relatively low involvement product, consumer belief in the price value schema dominates quality assessment. These findings mean that marketers cannot assume that intrinsic product attributes, even when experienced, will be interpreted or used accurately when evaluated by consumers. Hence results provide an illustration to managers of the importance of ensuring that consumers take the intended meaning from communicated intrinsic cues in particular.

Originality/value

The research significantly advances understanding of consumers’ use of extrinsic cues (price and COO specifically), and their respective influence in their determination of both expected and experienced quality.
