Chapter 8 Food Texture Characteristics – Fattiness, Cooking Method, Protein, and Body Chapter 8 Outline • Aperitif: Canoe Restaurant & Bar • Textures in Food • Fattiness in Food • Cooking Method and Protein Interactions • Overall Food Body Wine and Food Texture Interactions Chapter 8 Key Concepts •Food texture sensations •The impact of animal or vegetable fats and oils •Light-to-light and rich-to-rich matching How is Food Texture Traditionally Defined? • A standard scientific definition of texture is “the arrangement of the particles or constituent parts of a material that gives it its characteristic structure”. • The following sensations can be identified as part of food texture and tactile sense: smoothness, stickiness, graininess, fibrousness, and consistency. Food Texture Considerations • Whether light, medium, or full-bodied depends on a number of factors. • Primary elements: fat level, cooking method, and an overall feeling of body. • The above texture elements interact to impact the perception of the body, power, or weight of a particular dish. • Texture preferences are somewhat driven by cultural and personal differences. Fattiness in Food • Fats can be separated into numerous categories: saturated/unsaturated, fats/oils, invisible/visible, vegetable/animal, etc. • When considering pairing, it is important to establish whether a fat is natural or an added textural element. • Natural fats are found in foods like: dairy products, meats, seeds, and nuts. Fattiness in Food (2) • Added fats are found in: oils, shortenings, lard, butter, and margarine, and used for flavoring and mouth-feel. • The main objective of assessing fattiness in food from a texture perspective is determining mouth-feel characteristics such as smoothness, richness, and moistness. • Generally, a richer, fatter dish will require a richer, more full-bodied wine to compliment it. What Impact does Cooking Method and Protein Type Have on Texture Sensations? • Poaching or steaming maintains a light texture. • Frying or grilling provides additional texture. • A lighter protein prepared using a more robust cooking method will create a more powerful texture to supersede the texture of proteins in the higher body levels based on protein type alone.

Moist vs. Dry Methods • Moist heat cooking methods: are those where heat is conducted to the food item by a liquid and include: steaming, boiling, and braising. • Dry heat methods: are those where heat is conducted to the food item by: hot air (roasting, baking), hot metal (grilling, blackening), radiation (broiling), and hot fat (stir-frying, sauté, pan-frying, deep-frying). Overall Body • The overall food body is based on a person’s perception of the overall power or body of the prepared dish. • The following factors are considered: protein type, fat level, cooking method used, what the item is served with, and basically the range of texture factors that provide a feeling of weight or structure throughout the mouth. • The most basic assessment of food body is based on a continuum from light to very rich. • The type of food item and temperature at which it is served impact the perception of its food body. Light to Rich Pairing Implications Rich Take care to ensure the rich food does not overpower the light wine Usually reliable unless the combination is too rich Always a reliable combination Take care to ensure the rich wine does not overpower the light food Light Rich Food Light Wine What Wine Elements Interact with Food Fattiness and Body? • Wine tannin levels, • alcohol levels, • the presence and level of oak, • and overall body all have a strong relationship with food fattiness. Chapter 8 Lagniappe “Something extra” Body and Texture Matches in Food and Wine Results from Exercise 8.2 The old adage of “white wine with fish and red wine with meat” • Based on perceived texture and body rather than color. • The following findings are based on perceptions of an earlier class using Exercise 8.2 in Chapter 8. • Your perceptions may vary based on wine selections and food item preparation. Textures in Wine • A variety of terms and techniques to assess the level of texture in wine. • ‘Mouth-feel’ wheel. Characteristics included: – – – – surface smoothness, drying sensations, dynamic elements, weight, complexity and ripeness. • Too complex for even experienced wine judges. Primary Wine Texture Elements • Tannin level • Level of alcohol • Presence and level of oak • Overall feeling of body Issues: • High level of correlation among these elements • Study focus - tannin and overall body Definitions – Wine Texture • Tannin level: – Defining factor on the smooth (soft) to rough (hard) continuum. – Create tactile sensations of dryness, puckeriness and astringency. • Body: – The consistency or viscosity of wine. An impression of weight, size and volume. – Influenced primarily by the presence of alcohol. •Also, the presence of sugars, glycerol and tannins in wine. Textures in Food • Whether a food item is light, medium or full-bodied depends on a number of factors. • Primary considerations include: – Type of protein – Fat level in the protein or additional plate elements (natural or added) – The cooking method employed – Overall feeling of body across all of the food dish elements.

The bottom row is the mean for all wines. • Each food item column (chicken, pork and beef) provides the average level of match with each wine. What do the mean levels of match indicate? •Riesling provided a neutral match for across all three proteins. But, with much disagreement among students (standard deviation [s.d.] is relatively high). •The Pinot provided a neutral match with the chicken and a good match with the pork and beef. But, with substantial disagreement for the beef dish in particular. What do the mean levels of match indicate (2) ? • The Merlot had a good match with the pork and beef. The match with the chicken dropped to a refreshment level. There was substantial disagreement in match level with the beef dish. • The Cabernet Sauvignon had a neutral to good match with the pork and beef dishes. The match with the chicken dish was the lowest of all wines. What does this indicate overall? • The pork dish was perceived as the most wine-friendly at this tasting. • The Pinot Noir was perceived as the most versatile to serve with this selection of food dishes. • The braised beef dish lacked consensus on level of match. This may be due to the “bridging” technique of cooking with wine.

Deviation from Body-to-Body Match: Chicken •The Riesling and Chicken en Papillote had the closest body match and was perceived as nearly equal. •Pinto Noir was perceived as the next closest. •The Merlot and Cabernet clearly dominated this relationship. Deviation from Body-to-Body Match: Pork •Pinot Noir had the closest match with the grilled pork followed closely by the Merlot. •The Riesling and Cabernet were clearer not a close body match with the grilled pork. Deviation from Body-to-Body Match: Braised Beef • The Merlot had the closest body match with this dish. • The Cabernet Sauvignon slightly dominated the relationship. • The beef slightly dominated the Pinto Noir and completely overpowered the chicken dish. So What! •Table 1 and Figure 1 point out the strong relationship between evaluators perception of match and deviations from body-to-body match in wine and food. •Supports the notion of pleasant sensations through a matching perspective.
