Description

VEGETABLE-OIL-BASED FAT SYSTEMS COMPRISING LONG-CHAIN POLYUNSATURATED FATTY ACIDS AND USES THEREOF

TECHNICAL FIELD

[0001 ] The present disclosure relates generally to vegetable-oil-based fat systems including long-chain polyunsaturated fatty acids and uses of the same.

BACKGROUND

[0002] Consumers are paying increasing attention to not only the total fat content in food products, but also the nature of those fats. In general, foods low in saturated fats and trans-fats are viewed as healthier. Consumers also perceive some health benefits in increasing the levels of omega-3 fatty acids in one's diet.

[0003] Omega-3 fatty acids, also referred to as n-3 fatty acids, are polyunsaturated fatty acids having a carbon-carbon double bond in the third position from the end of the carbon chain. From a nutritional standpoint, the most important omega-3 fatty acids are probably a- linolenic acid ("ALA"), eicosapentaenoic acid ("EPA"), and docosahexaenoic acid ("DHA"). ALA is an 18-carbon fatty acid moiety having three carbon-carbon double bonds (commonly referred to as CI 8:3 in shorthand notation), one of which is at the n-3 position. EPA is a 20- carbon fatty acid moiety having 5 carbon-carbon double bonds ("C20:5") and DHA is a 22- carbon fatty acid moiety having 6 carbon-carbon double bonds ("C22:6").

[0004] Unfortunately, ALA, EPA, and DHA are all polyunsaturated fats that tend to oxidize, and thus rancidify, fairly readily. EPA (with 5 carbon-carbon double bonds) is significantly more prone to oxidation than ALA; DHA (with 6 carbon-carbon double bonds) is even more prone to oxidation than EPA. As a consequence, increasing the omega-3 fatty acid content tends to reduce the shelf life of many food products. These problems become particularly acute with fat systems including significant amounts of EPA and DHA.

SUMMARY

[0005] In one aspect, provided is a vegetable-oil-based fat system including long-chain polyunsaturated fatty acids, where the polyunsaturated fatty acids are selected from the group consisting of EPA and DHA. In some embodiments, the EPA and/or DHA are derived from a canola plant source. [0006] In another aspect, provided are methods for making vegetable-oil-based fat systems of the present disclosure.

[0007] In another aspect, provided are food products including the vegetable-oil-based fat systems.

DETAILED DESCRIPTION

[0008] Disclosed herein are vegetable-oil-based fat systems comprising canola oil including long-chain polyunsaturated fatty acids, where the polyunsaturated fatty acids are selected from the group consisting of EPA and DHA.

Vegetable Oil

[0009] As used herein, the term "vascular plant" refers to a plant having the vascular tissues xylem and phloem (e.g., palm plant, canola plant, cotton plant).

[0010] As used herein, the term "vegetable-oil-based fat system" means a solid fat composition including fats and/or oils derived entirely from a vascular plant source or more than one vascular plant source, such as, for example, a mixture of a palm oil, palm stearin, and a canola oil, or a mixture of a fully hydrogenated cotton oil and a canola oil. A vegetable-oil-based fat system of the present disclosure does not include fats and/or oils such as, for example, fats and/or oils derived from an animal source (e.g., butter, lard), a marine animal source (e.g., menhaden, anchovy), or a non- vascular plant source (e.g., an algae).

[001 i] As used herein, the term "canola oil" means an oil derived from a Brassica napus plant which produces seed that yields oil having less than 2% erucic acid and meal that contains no more than 30 micromoles of the following glucosinolates per gram of air-dry, oil- free solid: 3-butenyl glucosinolate, 4-pentenyl glucosinolate, 2-hydroxy-3 butenyl glucosinolate, and 2-hydroxy-4-pentenyl glucosinolate, i.e., a canola plant. The canola oil may include one or more omega-3 fatty acids, such as, for example, a-linolenic acid

("ALA"), docosahexaenoic acid ("DHA"), eicosapentaenoic acid ("EPA"), and stearidonic acid ("SDA"). In some embodiments, the DHA and EPA in the canola oil are produced by a vascular plant.

Preparation of a Vegetable-oil-based Fat System

[0026] Vegetable-oil-based fat systems of the present disclosure may be prepared by methods known to those or ordinary skill in the relevant arts. Preparation of fat systems are disclosed, for example, in U.S. Patent Pub. 2015/0064329.

Food Products

[0027] The vegetable-oil-based fat systems described herein can be incorporated into food products such as, for example, doughs or mixes to make food products such as donuts pizzas, crusts (e.g., pie crusts), cookies, biscuits, pastries (e.g., toaster pastries), bread, coffee creamers, the cream in a cream-filled food product, a frosting, or an icing.

[0028] Nutrition Facts label serving sizes are based on the amount of food customarily eaten at one time (called the "reference amount") as reported from nationwide food consumption surveys. (USDA & DHHS, 2000, Nutrition and Your Health: Dietary

Guidelines for Americans, Fifth Ed., Home and Garden Bulletin No. 23). Serving sizes are based on reference amounts in one of three ways (FDA Center for Food Safety and Applied Nutrition, 2000, Food Labeling and Nutrition). For bulk products, such as cereals and flour, the Nutrition Facts labels use common household terms such as cup, tablespoon, teaspoon, and fluid once at a quantity that is closest to the reference amount for that item. For products that are usually divided from consumption, such as cake or pizza, the serving size is a fractional amount of the product (e.g., " 1/4 pizza"). Products that come in defined, discrete units— such as eggs and sliced products-are normally listed as the number of whole units that most closely approximates the reference amount. For example, cookies have a reference amount of 30 g. Thus, the serving size on a package of cookies weighing about 30 g each would be " 1 cookie."

[0029] Food products can be evaluated using mechanized procedures such as DIPIX instrumentation (Ottawa, Canada). DIPIX technology provides inspection systems for food products. DIPIX Inspection Systems can inspect the 3-dimensional features such as thickness, height, and end-to-end or center-to-end slope, the 2-dimensional features such as length, width, minimum diameter, maximun diameter, and ovality, and bake color features such as bake color of edges, background, and ridges and valleys. DIPIX Inspection Systems also can inspect the optical density of a food product to detect holes and/or uncooked portions of a food product.

[0030] A food product and the effect of a particular ingredient or process also can be evaluated by examining the sensory attributes of a food product. Sensory attributes include, for example, color, tenderness, amount of cracking, gumminess, chewiness, moistness, hardness, flavor quality, mouth coating, finger oiliness, and graininess. Sensory attributes of food products may be determined by a trained sensory panel. A sensory panel refers to those individuals involved in the sensory evaluation of the edible food product. Panelists are pre- screened to be able to detect the flavor differences in the particular product tested and are trained in sensory descriptions. A panel provides qualitative and quantitative scores for the sensory evaluation that are referenced against calibrated standards.

[0031] Either or both the DIPIX results and the sensory panel results can be analyzed for statistical significance. Statistical significance generally refers to a p- value of less than 0.05, e.g., a p-value of less than 0.025 or a p-value of less than 0.01, using an appropriate parametric or non-parametric measurement, e.g., a one-tailed two-sample t-test. Standard deviation may also be measured for many features. EXAMPLES

Example 4. Sugar Cookies Including Vegetable-oil-based Fat Systems

[0044] The recipe shown in Table 4 is used to evaluate the prototype vegetable-oil- based fat systems in sugar cookies. The control sugar cookies included a Control Formula vegetable-oil-based fat systems in the dough instead of a Prototype vegetable-oil-based fat system.

Table 4. Sugar Cookie Recipe

[0045] The sugar, vegetable-oil-based fat system, salt, sodium bicarbonate and vanilla are mixed in a KITCHEN AID. 5 quart mixer on low speed (1) for 3 min. The eggs are added and mixed on low speed for 3 min. The milk is added and mixed on low speed for 1 min. The flours are sifted and added to the mixture. The mixture is mixed on low speed for 1 min. The cookie dough was deposited on a sheet pan liner using an ice cream scoop. The dough is baked at 400°F. for 12 min, and the cookies were placed on a rack to cool.

[0046] The cooled cookies were visually evaluated for size and color. Cookies prepared using Prototypes 1-3 were visually comparable (e.g., in size, color, surface texture, flatness, edge appearance) to cookies prepared using Control Formula 2. Oven smell and aroma of cooled cookies prepared using Prototypes 1-3 were comparable to cookies prepared using Control Formula 2. Surprisingly, cookies prepared using Prototypes 1-3 exhibited no "fishy" or other off-aromas.
