study investigates sensory properties of fishy ice cream

ice cream enriched with fish proteins may be acceptable after production, but storage is a problem, according to new research. the study, published in journal of the science of food and agriculture, investigated the effects of enriching the frozen confectionery product with fish protein to enhance its nutritional value. the authors, from the university of iceland and the iran fisheries research organization (ifro), found that that enriching ice cream with fish protein powder did not influence the sensory or chemical characteristics of the products after production, however unwanted attributes including fish flavour and off-odour were increased after more than 2 months of storage. “the objective of this work was to study the influence of fortifying ice cream with fish protein on chemical characteristics and sensory quality of the product in order to provide some useful information to food industry on how to develop such products and with the specific aim of increasing fish protein consumption,” said the authors, led by dr gholam shaviklo. “from the results it can be concluded that ice cream with fish protein can have good sensory quality for up to 2 months after production,” they added. fish fortification dr shaviklo and his colleagues explained that a variety of food products can be fortified without distinguishing them from non-fortified foods. they said that several ingredients are used for enhancing the functional value of food products, including fish protein, soy protein, whey protein, olive oil, fish oil, certain fruits, nuts and minerals and vitamins. ‘fishy’ flavours could be a problem when using fish protein ingredients, although, the researchers noted that most of the “fishy flavour components are removed” during fish protein production. the protein product (surimi) can then be dried and used for fortifying food products. “there are a growing number of food products enriched with fish ingredients on the market,” said shaviklo and colleagues. “fish ice cream is produced in japan by using different types of aquatic products,” they added. fish ice cream with crab (kani aisu), eel (unagi aisu), octopus (taco aisu), and with shrimp (sakura ebi aisu) are all available and accepted on japanese markets, said the authors. however, they said that many studies report negative effects both on flavour and odour if fish proteins they are used to enrich foods at inappropriate levels.

in-house trials on an optimised egg replacer formulation for pound cakes show it can match the quality of conventional recipes, and also improve on them through enhanced crumb structure and even air distribution, claims bakery ingredients supplier arla foods. kim jensen, technical manager for bakery, said recent analyses of water activity, resilience, crumb moistness and softness involving its milk protein-based nutrilac bk-7781 demonstrated that crumb taste and texture are similar to that of the standard egg-based recipe.

wacky food products are nothing new - take heinz’ launch in 2000 of green tomato ketchup - but the recent development of flavour-changing chewing gum still leaves the question: which trends will stick? as part of our special series on food in the future foodnavigator.com asked david jago, director of trends and innovation at market research firm mintel, to help us separate out the latest mad launches from the potentially mainstream, and to predict possible trends.
