Why Choose Guires's FRL as Your Food Product Development (FPD) Consultant and Partner?

There are several options in almost every product area in today’s market, and the difficulty is in coming up with unique items that stand out and connect with customers. Guires Food Research Lab (FRL) takes a holistic approach to creating food and beverage products. We define, demographically target, and build effective goods through a sequential process for category selection and comprehension. The client can visit the lab to learn the process. We offer unlimited rounds of revisions to ensure customer satisfaction. The final product prototype, along with the documentation process, including the video (through email), will be shipped to the client, and in case the client is not satisfied with the video, a food technology consultant will visit the place for the product demo at the client’s costs.

What are the different forms that you deliver the Food Product Formulations?

The food industry is witnessing a new form of consumption. Keeping that in mind, we can formulate the products in the form of ready-to-eat, ready-to-drink, ready-to-mix, ready-to-serve, and ready-to-cook food products. We use ingredients that offer an added value to the development and improve its indulgence and sustainability in terms of its functional ingredients, plant-based food dyes, and natural preservatives with a clean label.

What are the sectors Food Research Lab cover?

We cover a wide range of sectors such as soups, sauces and dips, chips, tortillas, dry beverage powder, plant-based products, masalas, puddings, instant mixes and many more.

How is sensory testing been carried out?

Our sensory examination leads to the precise formulation and recipe recommendations. We develop data-driven design models based on sensory research and customer insights. The fact-based design methodology used by Guires reduces risk and gives our clients market confidence while cutting development time in half. With our dedicated sensory lab facility, our team takes satisfaction in creating and optimizing successful products in the marketplace, generating a favourable return on investment, and developing brand advocates.

Incorporation of Fibers in Dough and Batter

Incorporating Fibres in Batters and dough to reduce the Oil Uptake

Cooking oil adds to taste, but is it healthy?

The oil used for deep-fried products not only serves as a source of cooking. The oil, however, also gets absorbed into the food by increasing the overall fat content. For the food to get cooked properly, the oil needs to be soaked completely. Foods containing higher calories and oily foods are related to obesity and heart conditions—for instance, foods such as French fries, which contain at least 340 calories. Consumers are much aware of dietary fibre for its beneficial physiological, metabolic effects. Healthier alternatives such as coconut oil and palm oil have been shown to reduced oil uptake. Olive oil is also a healthier choice for deep fry products. Whey isolates have also been shown to reduce oil uptake under pH and concentration local conditions. In boneless patties, whey protein solutions significantly reduced the oil by 37% compared to their control samples.

Aspects of oil uptake

It was found that the oil absorption was related to the content of amylose of the batter at an inverse relationship. On the contrary, the oil absorption and water loss were related linearly. It can be specified that the longer time the products stays in oil, the increased oil absorption. Batters and breading of the deep-fried snacks were also found to lower the oil absorption due to flours and starches in the batter. Blanching the chips or Pulsing the vegetable with voltage has also been shown to reduce oil uptake significantly.

High Fibre Rich products

Oats contain high levels of β-glucan, which are proven to reduce cholesterol levels and glycemic responses which affects the Glycaemic Index. Fibre extracted from wheat bran is an in effect stool bulking agent and relaxing constipation and related disorders. Many fibre-rich products are used in extruder based snacks, bakery products, breakfast cereals and roti based products have been developed.

High fibre rich products aid in fibre incorporation and the addition of enhanced functional properties with improved flavour and nutritional properties. Deep-fried items are commonly consumed in India, made from wheat flour and contains a high oil content of around 30%. The kneaded dough is shaped into different shapes, filled with various fillings and fried up in vegetable oil to form a crispy external texture. Due to the high-fat content, these deep-fried snacks are considered junk food even though the Indian and Middle Eastern consumers much enjoy them. The significant advantage of fibre incorporation in batter or dough formulations is that they reduce the uptake of oil consumption. The soluble fibres present in the oats hold water to form the viscosity and reduce oil uptake. They are also used as a fat subsitute in cake applications instead of traditional animal-based products.

The total dietary fibres, soluble and insoluble fibre contents of whole wheat flour, wheat and oat bran were investigated. Soybean fibre when used along with xanthan gum was found to inhibit the oil absorption in deep fried fish nuggets. Compared to the control samples, the soybean fibre incorporated fish nuggets had significantly lower fat content in the crust along with the core with the highest moisture retention. Moreover, enhanced crispiness, brighter golden yellow colour, and improved elasticity were achieved using soluble fibres. The overall moisture content was found to be in the range of 18.3 to 27 with respect to the oil content 19.3% to 30%. The deep-fried product with the fibre addition had an overall total dietary fibre of 4.2 grams and 1.3 grams of soluble dietary fibres per 100 grams, with the available oil content reduced by 20%. The final products’ acceptance rate increased from 65 to 95.

For extruded products, pellets play a crucial role in deciding the texture and the final properties such as hardness, density and expansion ratio. This could be based on the drying and conditioning; however, the identical factor responsible for the physical properties is not determined. The overall content and percentage of fat in potato pellets with 5-10% of fibre was found to be in the range of 32 to 37% higher than the control samples. Incorporating wheat and corn bran into the pellets increased snack fat content, but no overall results were observed in fortification.

Impact of the fibre rich products

Products with added fibre were found to influence the fat content with improved physical properties of the deep-fried snacks. Properties such as fat content, density, texture and lightness were found to be altered upon fortification. The rheology and oral processing is also impacted because of fibre incorporation. The suggested dosage amounts of fibre supplements were found to be based on the expansion degree required from the pellets. Similarly, fortifying the products with protein concentrates such as Whey protein resulted in various snack properties with different expansion and moisture contents.

Conclusion

The introduction of soluble fibres to pellets resulted in diminished starch content and higher far content. The highest degree was as high as 33 %. To achieve a suitable snacks expansion, the necessary conditions were supposed to be present with gelatinized starch. A low degree of gelatinized starch pellets was linked with common viscoelastic properties, resulting in a permanent, rough structure. Therefore, such additives like protein and fibre decide the properties of snacks to a degree based on the amount and compositions. The enhanced density of the snacks was achieved with the addition of corn germ with their interaction of gelatinizing starch and fat content during the preparation process. A few differences in the texture were observed between the fortified samples and their control. Fried snacks made with corn bran compared to the wheat bean were lighter with the addition of fibres. Corn germ also results in lighter coloured snacks.

Food Research Lab has developed numerous products for our clients. We have incorporated fibre in many of our formulations to reduce oil absoption and uptake. Some of the products include Pepperoni Chips, Ready-To-Eat Vegan omelette.
